python - 在MQL5中接受Python生成的套接字的输出

我已经创建了一个类似于以下内容的套接字文件，并希望该套接字的输出必须由MQL5读取。请参阅以下Python代码:

daemon.py

import socket
#import arcpy

def actual_work():
    #val = arcpy.GetCellValue_management("D:\dem-merged\lidar_wsg84", "-95.090174910630012 29.973962146120652", "")
    #return str(val)
    return 'dummy_reply'


def main():
    sock = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
    try:
        sock.bind( ('127.0.0.1', 6666) )

        while True:
            data, addr = sock.recvfrom( 4096 )
            reply = actual_work()
            sock.sendto(reply, addr)
    except KeyboardInterrupt:
        pass
    finally:
        sock.close()


if __name__ == '__main__':
    main()

client.py

import socket
import sys


def main():
    sock = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
    sock.settimeout(1)
    try:
        sock.sendto('', ('127.0.0.1', 6666))
        reply, _ = sock.recvfrom(4096)
        print reply
    except socket.timeout:
        sys.exit(1)
    finally:
        sock.close()


if __name__ == '__main__':
    main()

请帮助我通过MQL5接受套接字的输出

编辑过

我只希望reply应该在daemon.py产生的变量中的MQL5上被接受。我该怎么做？假设我希望MQL5应该打印来自Python的响应，如上例所示，我希望MQL5应该在字符串变量中以dummy_reply的形式给出输出。

ZeroMQ是否有可能？

我想使用MQL5而不是使用Python来完成client.py。请帮我。

最佳答案

请找到一个正在运行的示例。重要元素是在作为回复发送之前，创建有效负载的字节对象而不是字符串。套接字对象仅产生并提取字节

    import socket
    import threading
    import sys


    def actual_work(data):
       print(data)
       return b'ACK'

    def daemon():
       sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
       sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
       sock.bind(('127.0.0.1', 6666))
       print("Listening on udp %s:%i" % ('127.0.0.1', 6666))
       try:

          while True:
              data, addr = sock.recvfrom(4096)
              ack = actual_work(data)
              sock.sendto(ack, addr)
       except Exception as e:
          print(e)
       finally:

    def client():

           reply, _ = sock.recvfrom(4096)
           print(reply)
       except socket.timeout as e:
           print(e)
