I am trying to replicate the following POST request using the requests module in python:
POST /example/asdfas HTTP/1.1 Host: example.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Content-Type: multipart/form-data; boundary=---------------------------241652170216373 Content-Length: 279 -----------------------------241652170216373 Content-Disposition: form-data; name="value_1" 12345 -----------------------------241652170216373 Content-Disposition: form-data; name="value_2" 67890 -----------------------------241652170216373-- The documentation for requests suggests that the files argument should be used.
When I attempt the following call:
import requests requests.post('http://example.com/example/asdfas', files={'value_1': '12345', 'value_2': '67890'}) I get the following HTTP request:
'Accept': '*/*', 'Accept-Encoding': 'gzip, deflate, compress', 'Content-Length': '264', 'User-Agent': 'python-requests/2.2.1 CPython/3.3.2 Windows/7', 'Content-Type': 'multipart/form-data; boundary=273f13699c02429db4eb95c97f757d38' --273f13699c02429db4eb95c97f757d38 Content-Disposition: form-data; name="value_1"; filename="value_1" 12345 --273f13699c02429db4eb95c97f757d38 Content-Disposition: form-data; name="value_2"; filename="value_2" 67890 --273f13699c02429db4eb95c97f757d38-- I have also tried to use the data argument:
import requests requests.post('http://example.com/example/asdfas', data={'value_1': '12345', 'value_2': '67890'}) resulting in the following HTTP request:
'Content-Type': 'application/x-www-form-urlencoded', 'Content-Length': '27', 'User-Agent': 'python-requests/2.2.1 CPython/3.3.2 Windows/7', 'Accept': '*/*', 'Accept-Encoding': 'gzip, deflate, compress' value_2=67890&value_1=12345 The issue I'm having is that using the files argument results in a call that the server doesn't recognize, presumably due to the unexpected "filename" information sent in the HTTP request. Using the data argument sends the wrong Content-Type header.
The first request is known to be working on the server I wish to send the request to - what is the correct function call to identically replicate the first HTTP request?
Edit: Sample HTML form to replicate the working request:
<!DOCTYPE html> <html> <head> <title></title> </head> <body> <form action="http://example.com/example/asdfas" method="post" enctype="multipart/form-data"> <label for="v1">Value 1</label> <input id="v1" type="text" name="value_1"> <label for="v2">Value 2</label> <input id="v2" type="text" name="value_2"> <input type="submit"> </form> </body> </html>

The solution is to use tuples when passing parameters to the files argument:
import requests requests.post('http://example.com/example/asdfas', files={'value_1': (None, '12345'), 'value_2': (None, '67890')}) Works as expected:
'Accept': '*/*', 'Accept-Encoding': 'gzip, deflate, compress', 'Content-Length': '228', 'User-Agent': 'python-requests/2.2.1 CPython/3.3.2 Windows/7', 'Content-Type': 'multipart/form-data; boundary=85e90a4bbb05474ca1e23dbebdd68ed9' --85e90a4bbb05474ca1e23dbebdd68ed9 Content-Disposition: form-data; name="value_1" 12345 --85e90a4bbb05474ca1e23dbebdd68ed9 Content-Disposition: form-data; name="value_2" 67890 --85e90a4bbb05474ca1e23dbebdd68ed9-- If you love us?
