Google app engine 在Google App Engine中移植代理服务器时出错

我正在谷歌应用程序引擎上尝试端口代理（Python代理）；当我在开发模式下运行此代码，并试图通过此代理访问任何页面时，我收到以下错误：

INFO     2013-10-09 14:50:56,539 sdk_update_checker.py:245] Checking for updates to the SDK.

INFO     2013-10-09 14:51:04,289 module.py:599] default: "GET / HTTP/1.1" 500 228

代理代码如下

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()

您似乎已经定义了一个自定义类，并将其用作响应处理程序。但是响应处理程序有一个特定的约定：它们必须接受

请求

和

响应

，然后调用

初始化

。这通常通过从

webapp2.RequestHandler

继承来完成。请参阅上的webapp2文档

---

我不知道您希望如何传递

连接

、

地址

和

超时

参数。也许您想重写

get（）

，而不是

\uuuu init\uuuu（）

？

init接受4个参数，并传递3个参数。从那里开始？有调试器吗？看看你能用什么来称呼它。
