tornado-fastrpc 1.0.0

Asynchronous XML-RPC and FastPRC client for Python's Tornado

Non-blocking XML-RPC and FastRPC (see https://github.com/seznam/fastrpc) client for Python’s Tornado. If FastRPC is not available, only XML-RPC protocol will be supported. Python 2.7 and Python 3.4 (or higher) are supported.

Instalation

Requirements:

• pycurl

• Tornado 3.2 or higher

Optional requirements:

• fastrpc (libfastrpc + fastrpc Python’s module)

Instalation and tests:

python setup.py install
python setup.py test

Build Debian Jessie package (requires dpkg-buildpackage + lintian and dependencies in Build-Depends option in debian/control file.

python setup.py bdist_deb

Ussage

proxy = ServerProxy('http://example.com/RPC2:8000',
                    connect_timeout=5.0,
                    timeout=5.0,
                    use_binary=True)


class BazHandler(tornado.web.RequestHandler):

    @tornado.gen.coroutine
    def get(self):
        try:
            res = yield proxy.getData(123)
        except Exception as e:
            self.write('Error: {}'.format(e))
        else:
            self.write('Data: {}'.format(res.value))


class BarHandler(tornado.web.RequestHandler):

    @tornado.gen.coroutine
    def get(self):
        res = yield proxy.getData(123, quiet=True)
        if res.success:
            self.write('Data: {}'.format(res.value))
        else:
            self.write('Error: {}'.format(res.exception))

Documentation

ServerProxy class

class tornado_fastrpc.client.ServerProxy(uri, connect_timeout=5.0, timeout=5.0, use_binary=False, user_agent=None, keep_alive=False, use_http10=True, http_proxy=None, max_clients=10)

Async FastRPC client for Tornado, tt uses pycurl backend. Manages communication with a remote RPC server.

• url <string>

  URL address

• connect_timeout <float>

  Timeout for initial connection in seconds

• request_timeout <float>

  Timeout for entire request in seconds

• use_binary <bool>

  Force binary protocol

• user_agent <string>

  User-Agent string

• keep_alive <bool>

  Allow keep-alive connection

• use_http10 <bool>

  Force HTTP/1.0 protocol instead of HTTP/1.1

• http_proxy <string>

  HTTP proxy, eg. http://user:[e-mail]:80

• max_clients <int>

  Size of the Curl’s connection pool

Result object

class tornado_fastrpc.client.Result(success, value, exception)

Return type for FastRPC call. Contains attributes:

• success <bool>

  True if operation succeeded, else False

• value

  contains returning value if operation succeeded, else None

• exception <bool>

  contains instance of the exception if operation failed, else None

Fault object

class tornado_fastrpc.client.Fault(faultCode, faultString)

Exception, indicates an XML-RPC error.

• faultCode <string>

  Error code

• faultString <string>
