扭曲的http服务器错误

Question

我正在使用python扭曲模块来截取标题。我有以下脚本：

from twisted.web import proxy, http 
from twisted.internet import reactor 

g_port = 8080 #port for listening 
g_request =() # action, params, method 

class akaProxy(proxy.Proxy): 

    def dataReceived(self, data): 

     action = None 
     params = None 
     method = None 
     global g_request 

     headers = data.split("\n") 
     request = headers[0].split(" ") 
     params = headers[len(headers)-1] 

     method = request[0].lower() 
     action = request[1].lower() 

     print method, action 

     return proxy.Proxy.dataReceived(self, data) 

class ProxyFactory(http.HTTPFactory): 
    protocol = akaProxy 


factory = ProxyFactory() 
reactor.listenTCP(g_port, factory) 
reactor.run() 

当我把它用localproxy网页浏览器上运行（this URL）给我这个错误：

Unhandled Error

    "Request.finish called on a request after its connection was lost; " 
exceptions.RuntimeError: Request.finish called on a request after its connection was lost; use Request.notifyFinish to keep track of this. 

但它继续工作，任何人都可以解释错误以及如何能我修复它？

Answer 1

此消息出现在如下描述的情况中：您有一些处理http请求的代码，并且在http连接丢失之前，请求的finish方法没有被调用（意思是现在有没有办法将结果发送给请求者）。

你可能不关心这种情况。如果你不这样做，那么当你的请求的_disconnected属性为真时，你应该在你的代码中做些什么来保持Request.finish方法不被调用。那，或者只是忽略错误。
