Python requests - print entire http request (raw)?

Question

While using the requests module, is there any way to print the raw HTTP request?

I don't want just the headers, I want the request line, headers, and content printout. Is it possible to see what ultimately is constructed from HTTP request?

Answer 1

Since v1.2.3 Requests added the PreparedRequest object. As per the documentation "it contains the exact bytes that will be sent to the server".

One can use this to pretty print a request, like so:

import requests  req = requests.Request('POST','http://stackoverflow.com',headers={'X-Custom':'Test'},data='a=1&b=2') prepared = req.prepare()  def pretty_print_POST(req):     """     At this point it is completely built and ready     to be fired; it is "prepared".      However pay attention at the formatting used in      this function because it is programmed to be pretty      printed and may differ from the actual request.     """     print('{}\n{}\r\n{}\r\n\r\n{}'.format(         '-----------START-----------',         req.method + ' ' + req.url,         '\r\n'.join('{}: {}'.format(k, v) for k, v in req.headers.items()),         req.body,     ))  pretty_print_POST(prepared) 

which produces:

-----------START----------- POST http://stackoverflow.com/ Content-Length: 7 X-Custom: Test  a=1&b=2 

Then you can send the actual request with this:

s = requests.Session() s.send(prepared) 

These links are to the latest documentation available, so they might change in content: Advanced - Prepared requests and API - Lower level classes

Answer 2

import requests  response = requests.post('http://httpbin.org/post', data={'key1':'value1'}) print(response.request.url) print(response.request.body) print(response.request.headers) 

Response objects have a .request property which is the original PreparedRequest object that was sent.
