        "description": "====================================\nlti: Learning Tools Interoperability\n====================================\nThis library is a fork of lti_lti_py_\nIt has been modified to accept non-standard params and bubble up useful\nerror messages in the form of exceptions to the caller. \n\n``lti`` is a Python library implementing the\nLearning Tools Interoperability (LTI) standard.\nIt is based on lti_lti_py_,\nwhich is based on dce_lti_py_,\nwhich is based on ims_lti_py_.\n\n.. _lti_lti_py: https://github.com/pylti/lti\n.. _dce_lti_py: https://github.com/harvard-dce/dce_lti_py\n.. _ims_lti_py: https://github.com/tophatmonocle/ims_lti_py\n\n\nInstallation\n============\n\n.. code-block:: sh\n\n    pip install lti\n\n\nDependencies\n============\n\n* lxml_\n* oauthlib_\n* requests-oauthlib_\n\n.. _lxml: https://github.com/lxml/lxml\n.. _oauthlib: https://github.com/idan/oauthlib\n.. _requests-oauthlib: https://github.com/requests/requests-oauthlib\n\n\nUsage\n=====\n\nThe primary goal of this library is to provide classes\nfor building Python LTI tool providers (LTI apps).\nTo that end, the functionality that you're looking for\nis probably in the ``ToolConfig`` and ``ToolProvider`` classes (``ToolConsumer``\nis available too, if you want to consume LTI Providers).\n\n\nTool Config Example (Django)\n----------------------------\n\nHere's an example of a Django view you might use as the\nconfiguration URL when registering your app with the LTI consumer.\n\n.. code-block:: python\n\n    from lti import ToolConfig\n    from django.http import HttpResponse\n\n\n    def tool_config(request):\n\n        # basic stuff\n        app_title = 'My App'\n        app_description = 'An example LTI App'\n        launch_view_name = 'lti_launch'\n        launch_url = request.build_absolute_uri(reverse('lti_launch'))\n\n        # maybe you've got some extensions\n        extensions = {\n            'my_extensions_provider': {\n                # extension settings...\n            }\n        }\n\n        lti_tool_config = ToolConfig(\n            title=app_title,\n            launch_url=launch_url,\n            secure_launch_url=launch_url,\n            extensions=extensions,\n            description = app_description\n        )\n\n        return HttpResponse(lti_tool_config.to_xml(), content_type='text/xml')\n\n\nTool Provider OAuth Request Validation Example (Django)\n-------------------------------------------------------\n\n.. code-block:: python\n\n    from lti.contrib.django import DjangoToolProvider\n    from my_app import RequestValidator\n    from oauthlib.oauth1 import SignatureOnlyEndpoint\n\n    # create the tool provider instance\n    tool_provider = DjangoToolProvider.from_django_request(request=request)\n\n    # the tool provider uses the 'oauthlib' library which requires an instance\n    # of a validator class when doing the oauth request signature checking.\n    # see https://oauthlib.readthedocs.org/en/latest/oauth1/validator.html for\n    # info on how to create one\n    validator = RequestValidator()\n\n    # validate the oauth request signature\n    ok = tool_provider.is_valid_request(SignatureOnlyEndpoint, validator)\n\n    # do stuff if ok / not ok\n\n\nTool Consumer Example (Django)\n------------------------------\n\nIn your view:\n\n.. code-block:: python\n\n    def index(request):\n        consumer = ToolConsumer(\n            consumer_key='my_key_given_from_provider',\n            consumer_secret='super_secret',\n            launch_url='provider_url',\n            params={\n                'lti_message_type': 'basic-lti-launch-request'\n            }\n        )\n\n        return render(\n            request,\n            'lti_consumer/index.html',\n            {\n                'launch_data': consumer.generate_launch_data(),\n                'launch_url': consumer.launch_url\n            }\n        )\n\nAt the template:\n\n.. code-block:: html\n\n    <form action=\"{{ launch_url }}\"\n          name=\"ltiLaunchForm\"\n          id=\"ltiLaunchForm\"\n          method=\"POST\"\n          encType=\"application/x-www-form-urlencoded\">\n      {% for key, value in launch_data.items %}\n        <input type=\"hidden\" name=\"{{ key }}\" value=\"{{ value }}\"/>\n      {% endfor %}\n      <button type=\"submit\">Launch the tool</button>\n    </form>\n\n\nTesting\n=======\n\nUnit tests can be run by executing\n\n.. code-block:: sh\n\n    tox\n\nThis uses tox_ to set up and run the test environment.\n\n.. _tox: https://tox.readthedocs.org/\n",
