How to upload images using wordpress REST api in python?

I've figured it out!

With this function I'm able to upload images via the WP REST api to my site (Photo Gear Hunter.) The function returns the ID of the image. You can then pass that id to a new post call and make it the featured image, or do whatever you wish with it.

def restImgUL(imgPath):    url='http://xxxxxxxxxxxx.com/wp-json/wp/v2/media'    data = open(imgPath, 'rb').read()    fileName = os.path.basename(imgPath)    res = requests.post(url='http://xxxxxxxxxxxxx.com/wp-json/wp/v2/media',                        data=data,                        headers={ 'Content-Type': 'image/jpg','Content-Disposition' : 'attachment; filename=%s'% fileName},                        auth=('authname', 'authpass'))    # pp = pprint.PrettyPrinter(indent=4) ## print it pretty.     # pp.pprint(res.json()) #this is nice when you need it    newDict=res.json()    newID= newDict.get('id')    link = newDict.get('guid').get("rendered")    print newID, link    return (newID, link)

To specify additional fields supported by the api such as alt text, description ect:

from requests_toolbelt.multipart.encoder import MultipartEncoderimport requestsimport osfileName = os.path.basename(imgPath)multipart_data = MultipartEncoder(    fields={        # a file upload field        'file': (fileName, open(imgPath, 'rb'), 'image/jpg'),        # plain text fields        'alt_text': 'alt test',        'caption': 'caption test',        'description': 'description test'    })response = requests.post('http://example/wp-json/wp/v2/media', data=multipart_data,                         headers={'Content-Type': multipart_data.content_type},                         auth=('user', 'pass'))

thanks to @my Year Of Code.

my final working code:

import HOST = "https://www.crifan.com"API_MEDIA = HOST + "/wp-json/wp/v2/media"JWT_TOKEN = "eyJxxxxxxxxjLYB4"    imgMime = gImageSuffixToMime[imgSuffix] # 'image/png'    imgeFilename = "%s.%s" % (processedGuid, imgSuffix) # 'f6956c30ef0b475fa2b99c2f49622e35.png'    authValue = "Bearer %s" % JWT_TOKEN    curHeaders = {        "Authorization": authValue,        "Content-Type": imgMime,        'Content-Disposition': 'attachment; filename=%s' % imgeFilename,    }    # curHeaders={'Authorization': 'Bearer eyJ0xxxyyy.zzzB4', 'Content-Type': 'image/png', 'Content-Disposition': 'attachment; filename=f6956c30ef0b475fa2b99c2f49622e35.png'}    uploadImgUrl = API_MEDIA    resp = requests.post(        uploadImgUrl,        # proxies=cfgProxies,        headers=curHeaders,        data=imgBytes,    )

return 201 means Created OK

response json look like:

{  "id": 70393,  "date": "2020-03-07T18:43:47",  "date_gmt": "2020-03-07T10:43:47",  "guid": {    "rendered": "https://www.crifan.com/files/pic/uploads/2020/03/f6956c30ef0b475fa2b99c2f49622e35.png",    "raw": "https://www.crifan.com/files/pic/uploads/2020/03/f6956c30ef0b475fa2b99c2f49622e35.png"  },...
