Python HTTP服务器对POST请求没有响应

我想使用python制作一个HTTP服务器来托管我的网站。我已经实现了do_GET（）方法，它工作正常，但是当我尝试POST方法时，服务器没有响应，直到我重新加载页面。然后它醒来，完成POST，但意识到连接已经结束。之后，它为GET方法提供服务（因为我重新加载了页面）并继续正常运行。Python HTTP服务器对POST请求没有响应

我在客户端使用jQuery，但我也试过html窗体。即使我在另一个浏览器中打开该页面也没有改变，所以它必须是服务器端的例外。

下面是客户端的javascript：

function Send() 
     { 
      jQuery.post("address", "Blah!", function (data) { 
       //get response 
       alert(data); 
      }); 
     }

这里是服务器端的代码（我使用python 3.3.4）：

class MyHTTPRequestHandler(http.server.BaseHTTPRequestHandler): 
    def do_POST(self): 
     print("Data: " + str(self.rfile.read(), "utf-8")) #show request 

     response = bytes("This is the response.", "utf-8") #create response 

     self.send_response(200) #create header 
     self.send_header("Content-Length", str(len(response))) 
     self.end_headers() 

     self.wfile.write(response) #send response

这是从服务器日志：

Data: Blah!

你可以看到，第一行是经典的GET请求。然后我从浏览器调用POST，直到重新加载才发生任何事情。此时服务器将写入剩余的日志。

问题解决！代码载入收到的数据（位于do_POST()）。我只需指定要读取的数据量。

所以，只是不要使用rfile.read()，但rfile.read(numberOfBytes)。有多大POST信息会储存在标题：numberOfBytes = int(self.headers["Content-Length"])

的修复方法：

def do_POST(self): 
    length = int(self.headers["Content-Length"]) 
    print("Data: " + str(self.rfile.read(length), "utf-8")) 

    response = bytes("This is the response.", "utf-8") #create response 

    self.send_response(200) #create header 
    self.send_header("Content-Length", str(len(response))) 
    self.end_headers() 

    self.wfile.write(response) #send response
