我正在使用python并尝试在我的计算机和网站之间刮取HTTP流量,其中包括所有传入和传出请求,响应,如图像和外部呼叫等。
我试图在hit_site
函数中找到网络流量,但我找不到相关信息。
hit_site("http://www.google.com")
def hit_site(url):
print url
r = requests.get(url,stream = True)
print r.headers
print r.encoding
print r.status_code
print r.json()
print requests.get(url,stream=True)
print r.request.headers
print r.response.headers
for line in r.iter_lines():
print line
data = r.text
soup = BeautifulSoup(data)
return soup
我想要捕获的信息类型的示例如下(我使用fiddler2来获取此信息。所有这些以及更多来自访问groupon.com):

我非常感谢关于如何使用python捕获网络流量的任何想法。
答案 0 :(得分:9)
dpkt是一个用于解析TCP流量的广泛工具(用Python编写),includes support for decoding packets involved in the SSL handshake。另一个从Python运行和解码捕获的工具是pypcapfile。
请注意,要解码包含数据的SSL流量,需要知道私钥。对于您无法控制的第三方服务器(例如Google)而言,这有点问题,需要付出巨大努力来解决它。其中一种方法是使用已知的私钥设置代理以播放中间人(并将自签名CA安装到本地存储中以强制浏览器接受它)。
