week06 07 创建RPC SERVER 换个镜像安装下载

RPC server 使用python类库

https://pypi.org/project/python-jsonrpc/

和NPM 不一样他没有global选项他安装的就是全局的安装的类库叫python-jsonrpc

但是在代码用的叫pyjsonrpc 这个要注意

但是呢？

报错

这是因为镜像的问题换一个

重装一下

成功！

简单写一个验证是否工作就是2个数相加看返回的和对不对

""" Backend service """

import pyjsonrpc

SERVER_HOST = 'localhost'
SERVER_PORT = 4040


class RequestHandler(pyjsonrpc.HttpRequestHandler):
    """ RPC request handler """
    @pyjsonrpc.rpcmethod
    def add(self, num1, num2):  # pylint: disable=no-self-use
        """ Test method """
        print "add is called with %d and %d" % (num1, num2)
        return num1 + num2


# Threading HTTP Server
HTTP_SERVER = pyjsonrpc.ThreadingHttpServer(
    server_address=(SERVER_HOST, SERVER_PORT),
    RequestHandlerClass=RequestHandler
)

print "Starting HTTP server on %s:%d" % (SERVER_HOST, SERVER_PORT)

HTTP_SERVER.serve_forever()

service.py

说明至少没有语法错误
