I am developing a django application that primarily uses web browsers to
upload scientific data that includes some image files. Currently, the
application works fine when Firefox or Chrome are used. Both images and
other data are correctly uploaded.
Occasionally users need to upload larger amounts of data, so I want to
automate this using Python's Requests module. My python program currently
uploads non-image data, but Django is not receiving the image files. This
may be because I am not setting HTTP-headers correctly.
When the user agent is Firefox, requests received by Django include headers
like:
HTTP_ACCEPT_ENCODING gzip, deflate
HTTP_ACCEPT
text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
When the user agent is my standalone program, only:
HTTP_ACCEPT_ENCODING identity
My questions are:
1) What HTTP-headers is Django expecting?
2) Should I be gzipping the image files?
3) What is the correct way to do this?
A code snippet from my standalone program follows.
==================================
# loop to get messages from console
while True:
message = input("Enter msg string: ")
filename= input("Enter filename (or blank): ")
# GET
print("--- GET upload_msg")
# Create a GET request (but do don't sent it)
req = Request('GET', upload_msg_url, data= {})
# Send request
forms_dct = get_response(req)
# modify forms_dct from GET, and use in next get_response()
forms_dct['message_str'] = message
# open file for upload
fobj = open(filename,'rb')
# modify forms_dct from GET, and use in next get_response()
forms_dct['photo'] = filename
# Create files dictionary
files_dct = {filename:fobj}
# POST
print("--- POST upload_msg")
# Create a POST request (but do don't sent it)
req = Request('POST', upload_msg_url, data= forms_dct, files=
files_dct)
# Send request
forms_dct = get_response(req)
# close file
fobj.close()
==================================
Thanks.
