Python多线程启动http.server

OS: Windows 8.1 with update

关键字：Python3.4， http.server， Thread

 

例子代码如下：

import os

from threading import Thread

import time

import webbrowser



port_number = "8000"



def run_on(port):  

    os.system("python -m http.server " + port)

   

if __name__ == "__main__":

    server = Thread(target=run_on, args=[port_number])

    #run_on(port_number) #Run in main thread

    #server.daemon = True # Do not make us wait for you to exit  

    server.start()

    time.sleep(2) #Wait to start the server first



def test():

    url = "http://localhost:" + port_number

    webbrowser.open(url)

    print(url + " is opened in browser")



test()

代码解释：

1. os.system("python -m http.server " + port)，“python -m http.server 8000”是一个cmd，能够启动一个http server。

2. server = Thread(target=run_on, args=[port_number])， 创建一个线程用来启动http server。如果启动在主线程里面启动http server，将会阻塞主线程，而不能执行下面的代码。

3. server.start()， 启动线程。

4. time.sleep(2)，等待启动http server。

5. webbrowser.open(url)， 打开url。

 

另外一个例子启动/停止服务器

from threading import Thread

import webbrowser, http.server, socketserver

import time;



port_number = 8000



server = None

def startServer(port):

    Handler = http.server.SimpleHTTPRequestHandler

    global server

    server = socketserver.TCPServer(("", port), Handler)



    print("Start server at port", port)

    server.serve_forever()

   

def start(port):

    thread = Thread(target=startServer, args=[port])

    thread.start()

    

    startTime = int(time.time())

    while not server:

        if int(time.time()) > startTime + 60:

            print("Time out")

            break

    return server



def stop():

    if server:

        server.shutdown()

        

def openUrl():

    url = "http://localhost:" + str(port_number)

    webbrowser.open(url)

    print(url + " is opened in browser")



if __name__ == "__main__":

    start(port_number)

    openUrl()
