Question

我想更改异常挂钩，以返回自定义错误而不是远程错误。这是我的示例代码：

server.py

import zerorpc
import c

class ExceptionalRPC(object):
    def bad(self):
        raise KeyError

zero_ctx = zerorpc.Context()
test_middleware = c.ServerBeforeExecMiddleware()
zero_ctx.register_middleware(test_middleware)
s = zerorpc.Server(ExceptionalRPC(), context=zero_ctx)
s.bind("tcp://0.0.0.0:4242")
s.run()

client.py

import zerorpc
import c
zero_ctx = zerorpc.Context()
test_middleware = c.ServerBeforeExecMiddleware()
zero_ctx.register_middleware(test_middleware)

c = zerorpc.Client(context=zero_ctx)
c.connect("tcp://127.0.0.1:4242")

try:
    c.bad()
except Exception as b:
    print(type(b))

c.py

class ServerBeforeExecMiddleware(object):

    def __init__(self):
        self.called = False

    def server_inspect_exception(self, request_event, reply_event, task_context, exc_infos):
        args = list(reply_event.args)

        args.append({"name":"mahdieh"})
        reply_event._args = tuple(args)
        print(type(reply_event.args),reply_event.args)


    def client_handle_remote_error(self, event):
        for i in event.args:
            print(type(i),i)

当我使用python 2.7运行server.py并使用python 3.6运行client.py时，输出如下所示：

{b'name'：b'mahdieh'}

但是当我运行python 2.7的server.py和python 2.7的client.py时，输出看起来像这样： {'name'：'mahdieh'}

有解决此问题的工具吗？

如何修复python2.7和python3.x之间的问题zerorpc二进制转换？
