It lets you do all common task like -retrieving download status, manage queue, manage accounts, modify config and so on. - -This document is not intended to explain every function in detail, for a complete listing -see :class:`Api <module.Api.Api>`. - -Of course its possible to access the ``core.api`` attribute in plugins and hooks, but much more -interesting is the possibillity to call function from different programs written in many different languages. - -pyLoad uses thrift as backend and provides its :class:`Api <module.Api.Api>` as service. -More information about thrift can be found here http://wiki.apache.org/thrift/. - - -Using Thrift ------------- - -Every thrift service has to define all data structures and declare every method which should be usable via rpc. -This file is located :file:`module/remote/thriftbackend/pyload.thrift`, its very helpful to inform about -arguments and detailed structure of return types. However it does not contain any information about what the functions does. - -Assuming you want to use the API in any other language than python than check if it is -supported here http://wiki.apache.org/thrift/LibraryFeatures?action=show&redirect=LanguageSupport. - -Now install thrift, for instructions see http://wiki.apache.org/thrift/ThriftInstallation. -If every thing went fine you are ready to generate the method stubs, the command basically looks like this. :: - - $ thrift --gen (language) pyload.thrift - -You find now a directory named :file:`gen-(language)`. For instruction how to use the generated files consider the docs -at the thrift wiki and the examples here http://wiki.apache.org/thrift/ThriftUsage. - - -======= -Example -======= -In case you want to use python, pyload has already all files included to access the api over rpc. - -A basic script that prints out some information: :: - - from module.remote.thriftbackend.ThriftClient import ThriftClient, WrongLogin - - try: - client = ThriftClient(host="127.0.0.1", port=7227, user="User", password="yourpw") - except: - print "Login was wrong" - exit() - - print "Server version:", client.getServerVersion() - print client.statusDownloads() - q = client.getQueue() - for p in q: - data = client.getPackageData(p.pid) - print "Package Name: ", data.name - -That's all for now, pretty easy isn't it? -If you still have open questions come around in irc or post them at our pyload forum. - - -Using HTTP/JSON ---------------- - -Another maybe easier way, which does not require much setup is to access the JSON Api via HTTP. -For this reason the webinterface must be enabled. - -===== -Login -===== - -First you need to authenticate, if you using this within the webinterface and the user is logged the API is also accessible, -since they share the same cookie/session. - -However, if you are building a external client and want to authenticate manually -you have to send your credentials ``username`` and ``password`` as -POST parameter to ``http://pyload-core/api/login``. - -The result will be your session id. If you are using cookies, it will be set and you can use the API now. -In case you dont't have cookies enabled you can pass the session id as ``session`` POST parameter -so pyLoad can authenticate you. - -=============== -Calling Methods -=============== - -In general you can use any method listed at the :class:`Api <module.Api.Api>` documentation, which is also available to -the thriftbackend. - -Access works simply via ``http://pyload-core/api/methodName``, where ``pyload-core`` is the ip address -or hostname including the webinterface port. By default on local access this would be `localhost:8000`. - -The return value will be formatted in JSON, complex data types as dictionaries. -As mentionted above for a documentation about the return types look at the thrift specification file :file:`module/remote/thriftbackend/pyload.thrift`. - -================== -Passing parameters -================== - -To pass arguments you have two choices. -Either use positional arguments, eg ``http://pyload-core/api/getFileData/1``, where 1 is the FileID, or use keyword arguments -supplied via GET or POST ``http://pyload-core/api/getFileData?fid=1``. You can find the argument names in the :class:`Api <module.Api.Api>` -documentation. - -It is important that *all* arguments are in JSON format. So ``http://pyload-core/api/getFileData/1`` is valid because -1 represents an integer in json format. On the other hand if the method is expecting strings, this would be correct: -``http://pyload-core/api/getUserData/"username"/"password"``. - -Strings are wrapped in double qoutes, because `"username"` represents a string in json format. It's not limited to strings and intergers, -every container type like lists and dicts are possible. You usually don't have to convert them. just use a json encoder before using them -in the HTTP request. - -Please note that the data have to be urlencoded at last. (Most libaries will do that automatically)
