Python HTTP服務器對POST請求沒有響應

我想使用python製作一個HTTP服務器來託管我的網站。我已經實現了do_GET（）方法，它工作正常，但是當我嘗試POST方法時，服務器沒有響應，直到我重新加載頁面。然後它醒來，完成POST，但意識到連接已經結束。之後，它爲GET方法提供服務（因爲我重新加載了頁面）並繼續正常運行。Python HTTP服務器對POST請求沒有響應

我在客戶端使用jQuery，但我也試過html窗體。即使我在另一個瀏覽器中打開該頁面也沒有改變，所以它必須是服務器端的例外。

下面是客戶端的javascript：

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

這裏是服務器端的代碼（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

這是從服務器日誌：

Data: Blah!

你可以看到，第一行是經典的GET請求。然後我從瀏覽器調用POST，直到重新加載才發生任何事情。此時服務器將寫入剩餘的日誌。

問題解決！代碼載入收到的數據（位於do_POST()）。我只需指定要讀取的數據量。

所以，只是不要使用rfile.read()，但rfile.read(numberOfBytes)。有多大POST信息會儲存在標題：numberOfBytes = int(self.headers["Content-Length"])

的修復方法：

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
