How to print out http-response header in Python
Update: Based on comment of OP, that only the response headers are needed. Even more easy as written in below documentation of Requests module:
We can view the server's response headers using a Python dictionary:
>>> r.headers
{
'content-encoding': 'gzip',
'transfer-encoding': 'chunked',
'connection': 'close',
'server': 'nginx/1.0.4',
'x-runtime': '148ms',
'etag': '"e1ca502697e5c9317743dc078f67693f"',
'content-type': 'application/json'
}
And especially the documentation notes:
The dictionary is special, though: it's made just for HTTP headers. According to RFC 7230, HTTP Header names are case-insensitive.
So, we can access the headers using any capitalization we want:
and goes on to explain even more cleverness concerning RFC compliance.
The Requests documentation states:
Using Response.iter_content will handle a lot of what you would otherwise have to handle when using Response.raw directly. When streaming a download, the above is the preferred and recommended way to retrieve the content.
It offers as example:
>>> r = requests.get('https://api.github.com/events', stream=True)
>>> r.raw
<requests.packages.urllib3.response.HTTPResponse object at 0x101194810>
>>> r.raw.read(10)
'\x1f\x8b\x08\x00\x00\x00\x00\x00\x00\x03'
But also offers advice on how to do it in practice by redirecting to a file etc. and using a different method:
Using Response.iter_content will handle a lot of what you would otherwise have to handle when using Response.raw directly
How about something like this:
import urllib2
req = urllib2.Request('http://www.google.com/')
res = urllib2.urlopen(req)
print res.info()
res.close();
If you are looking for something specific in the header:
For Date: print res.info().get('Date')
