py-svrkit

just another square wheel

what is this wheel?

1.a rpc based on HTTP

2.a svrkit based on the rpc mentioned in 1.

what is svrkit?

something used in Wechat, which use an seq_id to selected server(Load Balancing) in the client side.

rpc demo

###1. write some methods on the sever side, and run it with a wsgi server

from svrkit.protocol.msgpack import MsgpackProto
from svrkit.server.wsgi import WsgiApplication
from svrkit.rpc.service import Service
from svrkit.rpc.decorator import rpc

class DemoService(Service):
    @rpc
    def echo(self, words: str, times: int):
        print(words)
        print(times)
        return words

service = DemoService('demo', req_proto=MsgpackProto, resp_proto=MsgpackProto)

if __name__ == '__main__':
    # You can use any Wsgi server. Here, we chose
    # Python's built-in wsgi server but you're not
    # supposed to use it in production.
    from wsgiref.simple_server import make_server

    wsgi_app = WsgiApplication(service)
    server = make_server('0.0.0.0', 8080, wsgi_app)
    server.serve_forever()

###2. call these methods on client side like this

from svrkit.rpc.client import Client
from svrkit.protocol.msgpack import MsgpackProto

if __name__ == '__main__':
    client = Client('localhost', '8080', 'demo', MsgpackProto, MsgpackProto)
    import datetime
    ret = client.echo(words=datetime.datetime.now(), times='1000')
    print(ret)

svrkit demo

1. server side

from svrkit.server.wsgi import WsgiApplication
from svrkit.rpc.decorator import rpc

class DemoSvrkitService(SvrkitService):
    @rpc
    def echo(self, seq_id, words):
        return seq_id, words

service = DemoSvrkitService('service.ini')

if __name__ == '__main__':
    # You can use any Wsgi server. Here, we chose
    # Python's built-in wsgi server but you're not
    # supposed to use it in production.
    from wsgiref.simple_server import make_server

    wsgi_app = WsgiApplication(service)
    server = make_server('0.0.0.0', 8081, wsgi_app)
    server.serve_forever()

2. client side

from svrkit.client import SvrkitClient

if __name__ == '__main__':

    client = SvrkitClient('client.ini')
    ret, data = client.echo(seq_id=3, words='ping pong is good')
    print(ret)
    print(data)

else ?
