我正在写一个代理,可以捕获我的硒测试中提出的请求。在硒我用的是接受客户端请求如何创建可以解码SSL流量的代理?

self.socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
### 
ssl.wrap_socket(self.socket, ssl_version=ssl.PROTOCOL_TLSv1, keyfile = ??, certfile = ???, server_side=True) 
### 
self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) 
self.socket.bind((self.hostname, self.port)) 
self.socket.listen(self.backlog) 
while True: 
    conn, addr = self.socket.accept() 
    logger.debug('Accepted connection %r at address %r' % (conn, addr)) 
    self.handle(conn,addr) 

而这正是该连接twith服务器

self.conn = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
### 
ssl.wrap_socket(self.socket, ssl_version=ssl.PROTOCOL_TLSv1, keyfile = ??, certfile = ???, server_side=True) 
### 
self.conn.connect((self.addr[0], self.addr[1])) 

我曾访问所作的部分原因

host = '10.203.9.156' 
profile = webdriver.FirefoxProfile() 
myProxy = "localhost:8899" 

proxy = Proxy({ 
'proxyType': ProxyType.MANUAL, 
'httpProxy': myProxy, 
'ftpProxy': myProxy, 
'sslProxy': myProxy, 
'noProxy': '' # set this value as desired 
}) 
driver = webdriver.Firefox(proxy=proxy) 

代理部分服务器。我的问题是什么应该是客户端请求接受部分的一部分,并在###之间将其转发给服务器,这将允许我以可读的格式捕获流量?证书不是很好。任何帮助将受到欢迎。

样板

SSL是提供双方各具有在专用/公共密钥对中的键中的一个之间的端至端的加密通信的协议。通常是一个浏览器和一个Web服务器。

在正常情况下,两个端点之间的任何设备都无法解密通信。

然而,有可能使用代理服务器来解密和重新加密通信,从而允许您的情况下进行拦截和解密。但是,它确实需要向客户机上的可信证书存储区添加附加证书(自动通过软件管理系统或由用户手动添加)。

解决您的问题

总体要创建“中间人”类型的代理,这意味着传递到代理服务器的每个请求都应该被解密并再次被加密,而客户端应该有匹配的SSL私钥。 尝试使用mitmproxy/libmproxy库。

退房可能proxy.py解决方案:

我用mitmproxy如你所说后,有趣的问题。它解释了如何安装(或成为CA权威机构)。但是我没有做到这一点,并且当我通过mitmproxy进行代理时,我能够看到所有SSL流量。这对我的系统有什么影响? – user1429322

@ user1429322:这可能意味着您已经设置Selenium/Firefox来忽略证书错误,如[在此描述](http://stackoverflow.com/questions/16879566/how-to-disable-firefoxs-untrusted-connection-warning - 使用 - 硒)。 –
