Python多線程啟動http.server

OS: Windows 8.1 with update

關鍵字：Python3.4， http.server， Thread

 

例子代碼如下：

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()

代碼解釋：

1. os.system("python -m http.server " + port)，“python -m http.server 8000”是一個cmd，能夠啟動一個http server。

2. server = Thread(target=run_on, args=[port_number])， 創建一個線程用來啟動http server。如果啟動在主線程里面啟動http server，將會阻塞主線程，而不能執行下面的代碼。

3. server.start()， 啟動線程。

4. time.sleep(2)，等待啟動http server。

5. webbrowser.open(url)， 打開url。

 

另外一個例子啟動/停止服務器

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()
