An Application object represents a web service described by a WADL
file.
>>> import os
>>> import sys
>>> import pkg_resources
>>> from wadllib.application import Application
The first argument to the Application constructor is the URL at which
the WADL file was found. The second argument may be raw WADL markup.
>>> wadl_string = pkg_resources.resource_string(
... 'wadllib.tests.data', 'launchpad-wadl.xml')
>>> wadl = Application("http://api.launchpad.dev/beta/", wadl_string)
Or the second argument may be an open filehandle containing the markup.
>>> cleanups = []
>>> def application_for(filename, url="http://www.example.com/"):
... wadl_stream = pkg_resources.resource_stream(
... 'wadllib.tests.data', filename)
... cleanups.append(wadl_stream)
... return Application(url, wadl_stream)
>>> wadl = application_for("launchpad-wadl.xml",
... "http://api.launchpad.dev/beta/")
Link navigation
===============
The preferred technique for finding a resource is to start at one of
the resources defined in the WADL file, and follow links. This code
retrieves the definition of the root resource.
>>> service_root = wadl.get_resource_by_path('')
>>> service_root.url
'http://api.launchpad.dev/beta/'
>>> service_root.type_url
'#service-root'
The service root resource supports GET.
>>> get_method = service_root.get_method('get')
>>> get_method.id
'service-root-get'
>>> get_method = service_root.get_method('GET')
>>> get_method.id
'service-root-get'
If we want to invoke this method, we send a GET request to the service
root URL.
>>> get_method.name
'get'
>>> get_method.build_request_url()
'http://api.launchpad.dev/beta/'
The WADL description of a resource knows which representations are
available for that resource. In this case, the server root resource
has a a JSON representation, and it defines parameters like
'people_collection_link', a link to a list of people in Launchpad. We
should be able to use the get_parameter() method to get the WADL
definition of the 'people_collection_link' parameter and find out more
about it--for instance, is it a link to another resource?
>>> def test_raises(exc_class, method, *args, **kwargs):
... try:
... method(*args, **kwargs)
... except Exception:
... # Contortion to support Python < 2.6 and >= 3 simultaneously.
... e = sys.exc_info()[1]
... if isinstance(e, exc_class):
... print(e)
... return
... raise
... raise Exception("Expected exception %s not raised" % exc_class)
>>> from wadllib.application import NoBoundRepresentationError
>>> link_name = 'people_collection_link'
>>> test_raises(
... NoBoundRepresentationError, service_root.get_parameter, link_name)
Resource is not bound to any representation, and no media media type was specified.
Oops. The code has no way to know whether 'people_collection_link' is
a parameter of the JSON representation or some other kind of
representation. We can pass a media type to get_parameter and let it
know which representation the parameter lives in.
>>> link_parameter = service_root.get_parameter(
... link_name, 'application/json')
>>> test_raises(NoBoundRepresentationError, link_parameter.get_value)
Resource is not bound to any representation.
Oops again. The parameter is available, but it has no value, because
there's no actual data associated with the resource. The browser can
look up the description of the GET method to make an actual GET
request to the service root, and bind the resulting representation to
the WADL description of the service root.
You can't bind just any representation to a WADL resource description.
It has to be of a media type understood by the WADL description.
>>> from wadllib.application import UnsupportedMediaTypeError
>>> test_raises(
... UnsupportedMediaTypeError, service_root.bind,
... '<html>Some HTML</html>', 'text/html')
This resource doesn't define a representation for media type text/html
The WADL description of the service root resource has a JSON
representation. Here it is.
>>> json_representation = service_root.get_representation_definition(
... 'application/json')
>>> json_representation.media_type
'application/json'
We already have a WADL representation of the service root resource, so
let's try binding it to that JSON representation. We use test JSON
data from a file to simulate the result of a GET request to the
service root.
>>> def get_testdata(filename):
... return pkg_resources.resource_string(
... 'wadllib.tests.data', filename + '.json')
>>> def bind_to_testdata(resource, filename):
... return resource.bind(get_testdata(filename), 'application/json')
The return value is a new Resource object that's "bound" to that JSON
test data.
>>> bound_service_root = bind_to_testdata(service_root, 'root')
>>> sorted([param.name for param in bound_service_root.parameters()])
['bugs_collection_link', 'people_collection_link']
>>> sorted(bound_service_root.parameter_names())
['bugs_collection_link', 'people_collection_link']
>>> [method.id for method in bound_service_root.method_iter]
['service-root-get']
Now the bound resource object has a JSON representation, and now
'people_collection_link' makes sense. We can follow the
'people_collection_link' to a new Resource object.
>>> link_parameter = bound_service_root.get_parameter(link_name)
>>> link_parameter.style
'plain'
>>> print(link_parameter.get_value())
http://api.launchpad.dev/beta/people
>>> personset_resource = link_parameter.linked_resource
>>> personset_resource.__class__
<class 'wadllib.application.Resource'>
>>> print(personset_resource.url)
http://api.launchpad.dev/beta/people
>>> personset_resource.type_url
'http://api.launchpad.dev/beta/#people'
This new resource is a collection of people.
>>> personset_resource.id
'people'
The "collection of people" resource supports a standard GET request as
well as a special GET and an overloaded POST. The get_method() method
is used to retrieve WADL definitions of the possible HTTP requests you
might make. Here's how to get the WADL definition of the standard GET
request.
>>> get_method = personset_resource.get_method('get')
>>> get_method.id
'people-get'
The method name passed into get_method() is treated case-insensitively.
>>> personset_resource.get_method('GET').id
'people-get'
To invoke the special GET request, the client sets the 'ws.op' query
parameter to the fixed string 'findPerson'.
>>> find_method = personset_resource.get_method(
... query_params={'ws.op' : 'findPerson'})
>>> find_method.id
'people-findPerson'
Given an end-user's values for the non-fixed parameters, it's possible
to get the URL that should be used to invoke the method.
>>> print(find_method.build_request_url(text='foo'))
http://api.launchpad.dev/beta/people?text=foo&ws.op=findPerson
>>> print(find_method.build_request_url(
... {'ws.op' : 'findPerson', 'text' : 'bar'}))
http://api.launchpad.dev/beta/people?text=bar&ws.op=findPerson
An error occurs if the end-user gives an incorrect value for a fixed
parameter value, or omits a required parameter.
>>> find_method.build_request_url()
Traceback (most recent call last):
...
ValueError: No value for required parameter 'text'
>>> find_method.build_request_url(
... {'ws.op' : 'findAPerson', 'text' : 'foo'})
... # doctest: +ELLIPSIS, +NORMALIZE_WHITESPACE
Traceback (most recent call last):
...
ValueError: Value 'findAPerson' for parameter 'ws.op' conflicts
with fixed value 'findPerson'
To invoke the overloaded POST request, the client sets the 'ws.op'
query variable to the fixed string 'newTeam':
>>> create_team_method = personset_resource.get_method(
... 'post', representation_params={'ws.op' : 'newTeam'})
>>> create_team_method.id
'people-newTeam'
findMethod() returns None when there's no WADL method matching the
name or the fixed parameters.
>>> print(personset_resource.get_method('nosuchmethod'))
None
>>> print(personset_resource.get_method(
... 'post', query_params={'ws_op' : 'nosuchparam'}))
None
Let's say the browser makes a GET request to the person set resource
and gets back a representation. We can bind that representation to our
description of the person set resource.
>>> bound_personset = bind_to_testdata(personset_resource, 'personset')
>>> bound_personset.get_parameter("start").get_value()
0
>>> bound_personset.get_parameter("total_size").get_value()
63
We can keep following links indefinitely, so long as we bind to a
representation to each resource as we get it, and use the
representation to find the next link.
>>> next_page_link = bound_personset.get_parameter("next_collection_link")
>>> print(next_page_link.get_value())
http://api.launchpad.dev/beta/people?ws.start=5&ws.size=5
>>> page_two = next_page_link.linked_resource
>>> bound_page_two = bind_to_testdata(page_two, 'personset-page2')
>>> print(bound_page_two.url)
http://api.launchpad.dev/beta/people?ws.start=5&ws.size=5
>>> bound_page_two.get_parameter("start").get_value()
5
>>> print(bound_page_two.get_parameter("next_collection_link").get_value())
http://api.launchpad.dev/beta/people?ws.start=10&ws.size=5
Let's say the browser makes a POST request that invokes the 'newTeam'
named operation. The response will include a number of HTTP headers,
including 'Location', which points the way to the newly created team.
>>> headers = { 'Location' : 'http://api.launchpad.dev/~newteam' }
>>> response = create_team_method.response.bind(headers)
>>> location_parameter = response.get_parameter('Location')
>>> location_parameter.get_value()
'http://api.launchpad.dev/~newteam'
>>> new_team = location_parameter.linked_resource
>>> new_team.url
'http://api.launchpad.dev/~newteam'
>>> new_team.type_url
'http://api.launchpad.dev/beta/#team'
Examining links
---------------
The 'linked_resource' property of a parameter lets you follow a link
to another object. The 'link' property of a parameter lets you examine
links before following them.
>>> import json
>>> links_wadl = application_for('links-wadl.xml')
>>> service_root = links_wadl.get_resource_by_path('')
>>> representation = json.dumps(
... {'scalar_value': 'foo',
... 'known_link': 'http://known/',
... 'unknown_link': 'http://unknown/'})
>>> bound_root = service_root.bind(representation)
>>> print(bound_root.get_parameter("scalar_value").link)
None
>>> known_resource = bound_root.get_parameter("known_link")
>>> unknown_resource = bound_root.get_parameter("unknown_link")
>>> print(known_resource.link.can_follow)
True
>>> print(unknown_resource.link.can_follow)
False
A link whose type is unknown is a link to a resource not described by
WADL. Following this link using .linked_resource or .link.follow will
cause a wadllib error. You'll need to follow the link using a general
HTTP library or some other tool.
>>> known_resource.link.follow
<wadllib.application.Resource object ...>
>>> known_resource.linked_resource
<wadllib.application.Resource object ...>
>>> from wadllib.application import WADLError
>>> test_raises(WADLError, getattr, unknown_resource.link, 'follow')
Cannot follow a link when the target has no WADL
description. Try using a general HTTP client instead.
>>> test_raises(WADLError, getattr, unknown_resource, 'linked_resource')
Cannot follow a link when the target has no WADL
description. Try using a general HTTP client instead.
Creating a Resource from a representation definition
====================================================
Although every representation is a representation of some HTTP
resource, an HTTP resource doesn't necessarily correspond directly to
a WADL <resource> or <resource_type> tag. Sometimes a representation
is defined within a WADL <method> tag.
>>> find_method = personset_resource.get_method(
... query_params={'ws.op' : 'find'})
>>> find_method.id
'people-find'
>>> representation_definition = (
... find_method.response.get_representation_definition(
... 'application/json'))
There may be no WADL <resource> or <resource_type> tag for the
representation defined here. That's why wadllib makes it possible to
instantiate an anonymous Resource object using only the representation
definition.
>>> from wadllib.application import Resource
>>> anonymous_resource = Resource(
... wadl, "http://foo/", representation_definition.tag)
We can bind this resource to a representation, as long as we
explicitly pass in the representation definition.
>>> anonymous_resource = anonymous_resource.bind(
... get_testdata('personset'), 'application/json',
... representation_definition=representation_definition)
Once the resource is bound to a representation, we can get its
parameter values.
>>> print(anonymous_resource.get_parameter(
... 'total_size', 'application/json').get_value())
63
Resource instantiation
======================
If you happen to have the URL to an object lying around, and you know
its type, you can construct a Resource object directly instead of
by following links.
>>> from wadllib.application import Resource
>>> limi_person = Resource(wadl, "http://api.launchpad.dev/beta/~limi",
... "http://api.launchpad.dev/beta/#person")
>>> sorted([method.id for method in limi_person.method_iter])[:3]
['person-acceptInvitationToBeMemberOf', 'person-addMember', 'person-declineInvitationToBeMemberOf']
>>> bound_limi = bind_to_testdata(limi_person, 'person-limi')
>>> sorted(bound_limi.parameter_names())[:3]
['admins_collection_link', 'confirmed_email_addresses_collection_link',
'date_created']
>>> languages_link = bound_limi.get_parameter("languages_collection_link")
>>> print(languages_link.get_value())
http://api.launchpad.dev/beta/~limi/languages
You can bind a Resource to a representation when you create it.
>>> limi_data = get_testdata('person-limi')
>>> bound_limi = Resource(
... wadl, "http://api.launchpad.dev/beta/~limi",
... "http://api.launchpad.dev/beta/#person", limi_data,
... "application/json")
>>> print(bound_limi.get_parameter(
... "languages_collection_link").get_value())
http://api.launchpad.dev/beta/~limi/languages
By default the representation is treated as a string and processed
according to the media type you pass into the Resource constructor. If
you've already processed the representation, pass in False for the
'representation_needs_processing' argument.
>>> from wadllib import _make_unicode
>>> processed_limi_data = json.loads(_make_unicode(limi_data))
>>> bound_limi = Resource(wadl, "http://api.launchpad.dev/beta/~limi",
... "http://api.launchpad.dev/beta/#person", processed_limi_data,
... "application/json", False)
>>> print(bound_limi.get_parameter(
... "languages_collection_link").get_value())
http://api.launchpad.dev/beta/~limi/languages
Most of the time, the representation of a resource is of the type
you'd get by sending a standard GET to that resource. If that's not
the case, you can specify a RepresentationDefinition as the
'representation_definition' argument to bind() or the Resource
constructor, to show what the representation really looks like. Here's
an example.
There's a method on a person resource such as bound_limi that's
identified by a distinctive query argument: ws.op=getMembersByStatus.
>>> method = bound_limi.get_method(
... query_params={'ws.op' : 'findPathToTeam'})
Invoke this method with a GET request and you'll get back a page from
a list of people.
>>> people_page_repr_definition = (
... method.response.get_representation_definition('application/json'))
>>> people_page_repr_definition.tag.attrib['href']
'http://api.launchpad.dev/beta/#person-page'
As it happens, we have a page from a list of people to use as test data.
>>> people_page_repr = get_testdata('personset')
If we bind the resource to the result of the method invocation as
happened above, we don't be able to access any of the parameters we'd
expect. wadllib will think the representation is of type
'person-full', the default GET type for bound_limi.
>>> bad_people_page = bound_limi.bind(people_page_repr)
>>> print(bad_people_page.get_parameter('total_size'))
None
Since we don't actually have a 'person-full' representation, we won't
be able to get values for the parameters of that kind of
representation.
>>> bad_people_page.get_parameter('name').get_value()
Traceback (most recent call last):
...
KeyError: 'name'
So that's a dead end. *But*, if we pass the correct representation
type into bind(), we can access the parameters associated with a
'person-page' representation.
>>> people_page = bound_limi.bind(
... people_page_repr,
... representation_definition=people_page_repr_definition)
>>> people_page.get_parameter('total_size').get_value()
63
If you invoke the method and ask for a media type other than JSON, you
won't get anything.
>>> print(method.response.get_representation_definition('text/html'))
None
Data type conversion
--------------------
The values of date and dateTime parameters are automatically converted to
Python datetime objects.
>>> data_type_wadl = application_for('data-types-wadl.xml')
>>> service_root = data_type_wadl.get_resource_by_path('')
>>> representation = json.dumps(
... {'a_date': '2007-10-20',
... 'a_datetime': '2005-06-06T08:59:51.619713+00:00'})
>>> bound_root = service_root.bind(representation, 'application/json')
>>> bound_root.get_parameter('a_date').get_value()
datetime.datetime(2007, 10, 20, 0, 0)
>>> bound_root.get_parameter('a_datetime').get_value()
datetime.datetime(2005, 6, 6, 8, ...)
A 'date' field can include a timestamp, and a 'datetime' field can
omit one. wadllib will turn both into datetime objects.
>>> representation = json.dumps(
... {'a_date': '2005-06-06T08:59:51.619713+00:00',
... 'a_datetime': '2007-10-20'})
>>> bound_root = service_root.bind(representation, 'application/json')
>>> bound_root.get_parameter('a_datetime').get_value()
datetime.datetime(2007, 10, 20, 0, 0)
>>> bound_root.get_parameter('a_date').get_value()
datetime.datetime(2005, 6, 6, 8, ...)
If a date or dateTime parameter has a null value, you get None. If the
value is a string that can't be parsed to a datetime object, you get a
ValueError.
>>> representation = json.dumps(
... {'a_date': 'foo', 'a_datetime': None})
>>> bound_root = service_root.bind(representation, 'application/json')
>>> bound_root.get_parameter('a_date').get_value()
Traceback (most recent call last):
...
ValueError: foo
>>> print(bound_root.get_parameter('a_datetime').get_value())
None
Representation creation
=======================
You must provide a representation when invoking certain methods. The
representation() method helps you build one without knowing the
details of how a representation is put together.
>>> create_team_method.build_representation(
... display_name='Joe Bloggs', name='joebloggs')
('application/x-www-form-urlencoded', 'display_name=Joe+Bloggs&name=joebloggs&ws.op=newTeam')
The return value of build_representation is a 2-tuple containing the
media type of the built representation, and the string representation
itself. Along with the resource's URL, this is all you need to send
the representation to a web server.
>>> bound_limi.get_method('patch').build_representation(name='limi2')
('application/json', '{"name": "limi2"}')
Representations may require values for certain parameters.
>>> create_team_method.build_representation()
Traceback (most recent call last):
...
ValueError: No value for required parameter 'display_name'
>>> bound_limi.get_method('put').build_representation(name='limi2')
Traceback (most recent call last):
...
ValueError: No value for required parameter 'mugshot_link'
Some representations may safely include binary data.
>>> binary_stream = pkg_resources.resource_stream(
... 'wadllib.tests.data', 'multipart-binary-wadl.xml')
>>> cleanups.append(binary_stream)
>>> binary_wadl = Application(
... "http://www.example.com/", binary_stream)
>>> service_root = binary_wadl.get_resource_by_path('')
Define a helper that processes the representation the same way
zope.publisher would.
>>> import cgi
>>> import io
>>> def assert_message_parts(media_type, doc, expected):
... environ = {
... 'REQUEST_METHOD': 'POST',

Error conditions
================
You'll get None if you try to look up a nonexistent resource.
>>> print(wadl.get_resource_by_path('nosuchresource'))

You'll get an exception if you try to look up a nonexistent resource
type.
>>> print(wadl.get_resource_type('#nosuchtype'))
Traceback (most recent call last):
KeyError: 'No such XML ID: "#nosuchtype"'
You'll get None if you try to look up a method whose parameters don't
match any defined method.

- Remove buildout support in favour of tox. [bug=922605]
- Adjust versioning strategy to avoid importing pkg_resources, which is slow
in large environments.
1.3.5 (2021-01-20)
==================
- Drop support for Python 3.2, 3.3, and 3.4.
- Accept Unicode parameter values again when performing multipart/form-data
encoding on Python 2 (broken in 1.3.3).

1.3.3 (2018-07-20)
==================
- Drop support for Python < 2.6.
- Add tox testing support.
- Implement a subset of MIME multipart/form-data encoding locally rather
than using the standard library's email module, which doesn't have good
handling of binary parts and corrupts bytes in them that look like line
endings in various ways depending on the Python version. [bug=1729754]
1.3.2 (2013-02-25)
==================
- Impose sort order to avoid test failures due to hash randomization.
LP: #1132125
- Be sure to close streams opened by pkg_resources.resource_stream() to avoid
test suite complaints.

- Correct the double pass through _from_string causing datetime issues
1.3.0 (2012-01-27)
==================
- Add Python 3 compatibility
- Add the ability to inspect links before following them.
- Ensure that the sample data is packaged.
1.2.0 (2011-02-03)
==================
- It's now possible to examine a link before following it, to see
whether it has a WADL description or whether it needs to be fetched
with a general HTTP client.
- It's now possible to iterate over a resource's Parameter objects
with the .parameters() method.
1.1.8 (2010-10-27)
==================
- This revision contains no code changes, but the build system was
changed (yet again). This time to include the version.txt file
used by setup.py.
1.1.7 (2010-10-26)

changed to include the sample data used in tests.
1.1.5 (2010-05-04)
==================
- Fixed a bug (Launchpad bug 274074) that prevented the lookup of
parameter values in resources associated directly with a
representation definition (rather than a resource type with a
representation definition). Bug fix provided by James Westby.
1.1.4 (2009-09-15)
==================
- Fixed a bug that crashed wadllib unless all parameters of a
multipart representation were provided.
