Robot Framework “multipart/form-data” REST request with multiple parameters - python-requests

Question

I am trying to use requestslibrary to upload some files, goal is to achieve this:
------WebKitFormBoundary61N9vqJ7380nh6iv
Content-Disposition: form-data; name="files"; filename="photo-2.jpeg"
Content-Type: image/jpeg
------WebKitFormBoundary61N9vqJ7380nh6iv
Content-Disposition: form-data; name="fileId"
b3duLWZpbGVzL2ZmZmZmZmZmYTQyNDVmODAvMjAxNTY*
------WebKitFormBoundary61N9vqJ7380nh6iv
Content-Disposition: form-data; name="extract"
false
------WebKitFormBoundary61N9vqJ7380nh6iv--
and now I have this, as per this:
${data}= Evaluate {'files': open("C:/testautomation/resources/Assets/photo-2.jpeg", 'r+b'), 'extract': (None, 'false'), 'fileId': (None, 'b3duLWZpbGVzL2ZmZmZmZmZmYTQyNDVmODAvMjAxNTY*')}
log ${data}
${result}= Post Request rest ${url} headers=${HEADERS} files=${data}
I THINK that the only bit I am missing is the "Content-Type: image/jpeg" from the first part, but how on earth I can add that? Currently the file gets uploaded, but it is not considered to be an image file.

Answer 1

The answer was:
${data}= Evaluate {'files': ('photo-1.jpeg', open("C:/testautomation-robot/resources/Assets/photo-1.jpeg", 'r+b'), 'image/jpeg'), 'extract': (None, 'false'), 'fileId': (None, 'b3duLWZpbGVzL2ZmZmZmZmZmYTQyNDVmODAvMjAxNTY*')}
Found an example from here: https://code.i-harness.com/en/q/bcfb9b
>>> url = 'http://httpbin.org/post'
>>> files = {'file': ('report.xls', open('report.xls', 'rb'), 'application/vnd.ms-excel', {'Expires': '0'})}
In the above, the tuple is composed as follows:
(filename, data, content_type, headers)

Create a python resources and call it through robot framework:
and call it through robot framework
Call params from robotframework:
upload multipart files post request ${headers} ${url} resources/files/upload_file/testfile1_upload.pdf
