python请求中单个文件的内容类型

Question

I want to request to my server running in python flask with file and some meta information. Hence my request content-Type will be 'multipart/form-data. Is there a way i can set the content type of file like image/jpg, image/gif etc... How do i set the content-type for the file. Is it possible or not

Answer 1

If you make each file specification a tuple, you can specify the mime type as a third parameter:

files = {
    'file1': ('foo.gif', open('foo.gif', 'rb'), 'image/gif'),
    'file2': ('bar.png', open('bar.png', 'rb'), 'image/png'),
}
response = requests.post(url, files=files)

You can give a 4th parameter as well, which must be a dictionary with additional headers for each part.

Answer 2

reference

    import requests

    url = "http://png_upload_example/upload"
    # files = [(<key>, (<filename>, open(<file location>, 'rb'), <content type>))]
    files = [('upload', ('thumbnail.png', open('thumbnail.png', 'rb'), 'image/png'))]

    response = requests.request("POST", url, files = files)
