在python中手動實現HTTP GET

我想在一個類的python中實現一個簡單的HTTP Web服務器，並且卡住了。目前我已經硬編碼讓事情變得更簡單，但我無法弄清楚它爲什麼不起作用。在python中手動實現HTTP GET

#Python 2 
import socket 
import threading 

class socketEcho(threading.Thread): 
    def __init__(self,conn): 
    super(socketEcho,self).__init__() 
    self.conn = conn 

    def run(self): 
    while 1: 
     data = self.conn.recv(1024) 
     if not data: 
     print 'Break' 
     break 
     data = """GET /index.html HTTP/1.1 
     host: www.esqsoft.globalservers.com 

     """ 
     dataList = data.split() 
     URI = dataList[1] 
     URI = URI[1:] 
     hostAddress = dataList[4]  
     try: 
     file = open(URI,'r').read() 
     result = "HTTP/1.1 200 OK \r\nContent-Type: text/html\r\n\r\n" 
     result = result + file 
     except IOError as e: #HTTP 404 
     print "Error" 
     pass  
     #conn.send(data) 
     print "Sending" 
     print result 
     try: 
     self.conn.send(result) 
     except: 
     print "Send Error" 
    HOST = '' 
    PORT = 50420 
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
    s.bind((HOST,PORT)) 
    s.listen(2) #Blocks, accept only one connection 
    while True: 
     newSock, addr = s.accept() 
     print 'Connected by', addr 
     newConn = socketEcho(newSock) 
     newConn.start()

當我嘗試我borswer（火狐）發送到本地主機：50420它得到200 OK代碼就好了，但後來它只是等待那裏，永遠不會顯示該頁面。因爲我查看了結果變量的輸出結果，它看起來很好，所以我不知道發生了什麼，有什麼建議嗎？這裏是在發送結果變量前打印出來的結果。

HTTP/1.1 200 OK 
Content-Type: text/html 

<html> 

    <head> 
    </head> 

    <body> 

     <h1>Hello World</h1> 
     <p>Yes, this does indeed work</p> 
     <p><a href="http://www.google.com">Google</a></p> 
     <!--<a href="http://knuth.luther.edu/~ranuha01/hello.html">Link Test</a>--> 
     <!--<img src="earth.jpg" alt="Earth picture" height="100">--> 
     <ul> 
      <li><b>One</b></li> 
      <ul> 
       <li>One and a half</li> 
      </ul> 
      <li><b>Two</b></li> 
     </ul> 

    </body> 

</html>

首先，您應該關閉處理程序中的conn;第二，不要在運行中放置一個循環（self），事件循環是主要的。

#!/usr/bin/env python 
# -*- coding: utf-8 -*- 
#Python 2 
import socket 
import threading 

class socketEcho(threading.Thread): 
    def __init__(self,conn): 
     super(socketEcho,self).__init__() 
     self.conn = conn 

    def run(self): 
     data = self.conn.recv(1024) 
     if not data: 
     print 'Break' 
     self.conn.close() 
     return 
     data = """GET /index.html HTTP/1.1 
     host: www.esqsoft.globalservers.com 

     """ 
     dataList = data.split() 
     URI = dataList[1] 
     URI = URI[1:] 
     hostAddress = dataList[4]  
     try: 
     file = open(URI,'r').read() 
     result = "HTTP/1.1 200 OK \r\nContent-Type: text/html\r\n\r\n" 
     result = result + file 
     except IOError as e: #HTTP 404 
     print "Error" 
     pass  
     #conn.send(data) 
     print "Sending" 
     print result 
     try: 
     self.conn.send(result) 
     self.conn.close() 
     except: 
     print "Send Error" 

HOST = '' 
PORT = 50420 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
s.bind((HOST,PORT)) 
s.listen(2) #Blocks, accept only one connection 
while True: 
    newSock, addr = s.accept() 
    print 'Connected by', addr 
    newConn = socketEcho(newSock) 
    newConn.start()
