[Python]requests 得到headers解析为dic

我们看看headers的type，是CaseInsensitiveDict类.

r = requests.get("http:...")
In [99]: type(r.headers)
Out[99]: requests.structures.CaseInsensitiveDict

不能直接拿来用

• 解决方法

In [96]: json.dumps(dict(r.headers))
Out[96]: '{"x-powered-by": "PHP/5.3.3", "transfer-encoding": "chunked", "content-encoding": "gzip", "server": "nginx/1.8.0", "connection": "keep-alive", "date": "Mon, 25 Jan 2016 09:56:54 GMT", "content-type": "text/html; charset=UTF-8", "x-pingback": "http://xiaorui.cc/xmlrpc.php"}'
 
In [97]: json.loads(json.dumps(dict(r.headers)))
Out[97]:
