Question

I’m trying to modify the example in the requests library documentation to include a file uploaded from a user (to an appengine app). I have tried the following:

from libs import requests

file_data = self.request.POST['file_to_upload']
the_file = file_data
send_url = "http://httpbin.org/post"
values = {
          'user_id' : '1234',
          'file_name' : 'some_file.pdf'
          }

r = requests.post(send_url, files=the_file)
logging.info(r.content)

However this returns

 {
  "origin": "81.178.201.22", 
  "files": {}, 
  "form": {}, 
  "url": "http://httpbin.org/post", 
  "args": {}, 
  "headers": {
    "Content-Length": "0", 
    "Accept-Encoding": "identity, deflate, compress, gzip", 
    "Connection": "keep-alive", 
    "Accept": "*/*", 
    "User-Agent": "python-requests/0.11.1 AppEngine-Google; (+http://code.google.com/appengine)", 
    "Host": "httpbin.org", 
    "Content-Type": ""
  }, 
  "json": null, 
  "data": ""
}

i.e. there is no file received. I’ve also tried sending the_file as

file_data.file 
file_data.file.read() 

however these also fail. Ultimately I want to include both teh “values” and the file in the same post request, so something like:

r = requests.post(send_url, data=values, files=the_file)

However this isn’t working either – I guess I need to fix the above code first. Any idea as to what I’m doing wrong?

the requests library is not supported on GAE.
