在Google App Engine中移植代理服務器時出錯

我試圖在Google App Engine上移植代理（Python代理）當我以開發模式運行這個代碼，並試圖通過這個代理我收到以下錯誤訪問任何頁面：在Google App Engine中移植代理服務器時出錯

代理的代碼如下

class ConnectionHandler: 
    def __init__(self, connection, address, timeout): 
     self.initialize(request, response); 
     self.client = connection 
     self.client_buffer = '' 
     self.timeout = timeout 
     self.method, self.path, self.protocol = self.get_base_header() 
     if self.method=='CONNECT': 
      self.method_CONNECT() 
     elif self.method in ('OPTIONS', 'GET', 'HEAD', 'POST', 'PUT', 
          'DELETE', 'TRACE'): 
      self.method_others() 
     self.client.close() 
     self.target.close()

init需要4個參數，並且你傳遞它3.從那裏開始？有一個調試器？看看你可以真正調用它。 –

你似乎已經定義一個自定義類，並將其用作響應處理程序。但響應處理人員有特定的合同：他們必須接受request和response，然後致電initialize。通常通過繼承webapp2.RequestHandler完成。請參閱overriding __init__上的webapp2文檔。

我不知道你是如何期待您connection，address和timeout參數傳遞。也許你打算覆蓋get()而不是__init__()？
