Tcp <；类别'_pickle.UnpicklingError'>；-无效的加载键&x27\x00和x27；在ZMQ socket.recv_pyobj（）中

我已参考了相关查询，无法修复上述错误。我正在两个独立进程之间运行服务器和客户端python对象共享。客户端需要向服务器发送dict或tuple。 我已尝试将协议更改为pickle.DEFAULT\u协议和pickle.HIGHEST\u协议。问题仍然没有解决…但我们可以打印我发送的口述

服务器代码：

import zmq
import socket
import sys
import datetime
import pickle

def errorhandling(name: str, msg: str) -> None:
        """
        To handle Error in the API and Strategies, if you call this
        """
        try:
            print(f" {datetime.datetime.now().time()}| ERROR |{name} | {msg} | {sys.exc_info()[0]} -"
                  f" {sys.exc_info()[1]} | Line No:{sys.exc_info()[2].tb_lineno}")
                          
        except Exception as e:
            print("error", f" {name} | ErrorHandlingError - {e}")

ip = socket.gethostbyname(socket.gethostname())

ordcontext = zmq.Context()
ordsocket = ordcontext.socket(zmq.XREP)
ordsocket.bind(f"tcp://{ip}:7712")

def ordersocket():
    print("Order socket Running")
    while True:
        try:
            #orddata = self.ordsocket.recv().decode('utf-8', 'ignore')
            orddata = ordsocket.recv_pyobj()
            #orddata2 = pickle.loads(orddata)
            print(orddata)
        except Exception:
            errorhandling(name="ordername",
                          msg="ordersocket")
                
    print("Order socket NOT Running")
            
ordersocket()

客户端代码：

import zmq
import time
import socket
import pickle
ip = socket.gethostbyname(socket.gethostname())
orcontext = zmq.Context()
orsocket = orcontext.socket(zmq.XREQ)
orsocket.connect(f"tcp://{ip}:7712")

def sendorder():
    while True:
        data = {"A": "Nameofstg", "LTP": 1200, "QTY":200, "SS":"Now", "PP":230}
        orsocket.send_pyobj(obj=data,protocol=pickle.HIGHEST_PROTOCOL)
        time.sleep(3)
        
sendorder()

错误（打印语句时）：

-无效的加载密钥'\x00'。

11:34:49.665037 |错误| ordername | ordersocket |-加载键无效，'\x00'第35行

我不确定您的代码中有什么问题，但请尝试下面的代码，它可以工作。实际上，您不需要pickle，

套接字。send_pyobj

可以用来发送字典之类的对象

假设

master.py

和

worker.py

位于相同的

dir

下

master.py

import zmq
import sys
import pexpect 
from getpass import getuser
from socket import gethostname


python = sys.executable
context = zmq.Context()
socket = context.socket(zmq.REP)
port = socket.bind_to_random_port("tcp://*")
server_host = gethostname()
server_socket = "%s:%s" % (server_host, port)

worker_command = "%s -m worker" % python + " %i " + server_socket
children = []
for ind in range(4):
    child = pexpect.spawn(worker_command % ind)
    children.append(child)
           
active = 4
while True:
    message = socket.recv_pyobj()
    print(message)
    socket.send_pyobj('task done')
    active -= 1
    if active == 0:
        break

import os
import sys
import zmq
from socket import gethostname

    
if __name__ == '__main__':
      
      
    import logging

    logging.basicConfig(filename = f"log")
    try:
        server_socket = sys.argv[-1]
        worker_id = int(sys.argv[-2])
        port_number = int(server_socket.split(':')[-1])
        
        context = zmq.Context()
        socket = context.socket(zmq.REQ)
        socket.connect('tcp://%s' % server_socket)
        
        data = {"A": "Nameofstg_%i" % worker_id}
        socket.send_pyobj(data)
        socket.recv_pyobj()
    except Exception as e:
        logging.exception(e)

和

worker.py

import zmq
import sys
import pexpect 
from getpass import getuser
from socket import gethostname


python = sys.executable
context = zmq.Context()
socket = context.socket(zmq.REP)
port = socket.bind_to_random_port("tcp://*")
server_host = gethostname()
server_socket = "%s:%s" % (server_host, port)

worker_command = "%s -m worker" % python + " %i " + server_socket
children = []
for ind in range(4):
    child = pexpect.spawn(worker_command % ind)
    children.append(child)
           
active = 4
while True:
    message = socket.recv_pyobj()
    print(message)
    socket.send_pyobj('task done')
    active -= 1
    if active == 0:
        break

import os
import sys
import zmq
from socket import gethostname

    
if __name__ == '__main__':
      
      
    import logging

    logging.basicConfig(filename = f"log")
    try:
        server_socket = sys.argv[-1]
        worker_id = int(sys.argv[-2])
        port_number = int(server_socket.split(':')[-1])
        
        context = zmq.Context()
        socket = context.socket(zmq.REQ)
        socket.connect('tcp://%s' % server_socket)
        
        data = {"A": "Nameofstg_%i" % worker_id}
        socket.send_pyobj(data)
        socket.recv_pyobj()
    except Exception as e:
        logging.exception(e)

通过运行

python master.py

，您可以看到，四个工作程序发送的字典可以被master成功接收，实际上，您不需要

pickle

，因为我们使用

socket.sendpyobj

---

您可能还注意到，在

worker.py

中，我使用了

logging.basicConfig（filename=f“log”）

。这样做，可以捕获工作进程中的

异常。
是否有人可以回复查询…帮助我out@ManjunathanVenkatesan嗨，Manjunathan Venkatesan，你的问题解决了吗？
