How to specify form field and file type with Requests

Question

I want to upload an image using requests module (Python 3). Sadly, the server answers my request with an error, saying that I should only upload files of type jpg, png or gif.
I guess I should fill every field of the form, but I want to figure out how despite all my tests.

Here is the HTML form :

<form class="upload" enctype="multipart/form-data" action="?action=upload" method="post">
            <h3>Envoyez votre image !</h3>
    <input name="MAX_FILE_SIZE" value="15360000" type="hidden" /> 
    <input name="img" size="30" type="file" />
    <input value="Envoyer" type="submit" />
</form>

I use this Python code :

with open(image, 'rb') as img:
    toup = {'img': (os.path.basename(image), img)}
    res= requests.post('http://url/?action=upload', files = toup)

How can I fill the MAX_FILE_SIZE field and specify the type of the uploaded file?

Answer 1

MAX_FILE_SIZE seems to be a normal HTTP POST data:

with open(image, 'rb') as img:
    toup = {'img': (os.path.basename(image), img)}
    res= requests.post('http://url/?action=upload', files = toup, data={'MAX_FILE_SIZE': '15360000'})

You could set the mime type of the file:

toup = {'img': (os.path.basename(image), img, 'image/jpeg')}

To get exact MIME of the file, you can use mimetypes library.
