Question

我的代码有问题，我想通过套接字在虚拟机上运行命令。我发现多个任务，命令有问题。例如，如果我打开Excel，我的套接字服务器已冻结，并且在手动关闭excel应用程序之前无法通过cmd运行其他命令。

在虚拟机上一次打开多个应用程序时，应该更改什么代码？（例如，我想一次打开四个xlsx文件）

Server.py

import socket
import subprocess
import os
from threading import Thread


def check_ping(hostname):
    response = os.system("ping " + hostname)
    # and then check the response...
    if response == 0:
        pingstatus = "Network Active"
    else:
        pingstatus = "Network Error"

    return(pingstatus)

def run_path(path):
    response = os.system(path)
    # and then check the response..
    return('ok')



def Main():
    host = "localhost"
    port = 5000

    mySocket = socket.socket()
    mySocket.bind((host,port))

    mySocket.listen(1)
    conn, addr = mySocket.accept()
    print ("Connection from: " + str(addr))
    while True:
            data = conn.recv(1024).decode()
            if not data:
                    break
            #print ("from connected  user: " + str(data))

            #data = str(data)
            #hostname = data.replace('ping ', '')

            print ("sending: " + str(data))
            #print(hostname)
            conn.send(data.encode())
            if 'ping' in str(data):
                hostname = data.replace('ping ', '')
                pingstatus = check_ping(hostname)
                print(pingstatus)
            elif 'open' in str(data):
                path = str(data).replace('open ', '')

                run_path(path)





    conn.close()

if __name__ == '__main__':
    Main()

Client.py

import socket

def Main():
        host = '127.0.0.1'
        port = 5000

        mySocket = socket.socket()
        mySocket.connect((host,port))

        message = input(" -> ")

        while message != 'q':
                mySocket.send(message.encode())
                data = mySocket.recv(1024).decode()

                print ('Received from server: ' + data)

                message = input(" -> ")

        mySocket.close()

if __name__ == '__main__':
    Main()

您可以在上一个命令返回之前运行新命令，而不必等待该事件。这意味着您应该使用子流程模块而不是system函数：

def run_path(path):
    response = subprocess.Process(path, shell=True)
    # and then continue without waiting...
    return('ok')

但是，如果您想将任何东西退还给对等方，则没有任何意义。此外，从远程客户端启动GUI程序而无法控制它甚至停止它也没有任何意义。

恐怕你在这里追怪怪的动物...
