I'm working with wechat APIs ... here I've to upload an image to wechat's server using this API http://admin.wechat.com/wiki/index.php?title=Transferring_Multimedia_Files

url = 'http://file.api.wechat.com/cgi-bin/media/upload?access_token=%s&type=image'%access_token
files = {
    'file': (filename, open(filepath, 'rb')),
    'Content-Type': 'image/jpeg',
    'Content-Length': l

If you have CURL then you can directly get request from Postman.

import requests

url = "your URL"

payload={}
files=[
  ('upload_file',('20220212235319_1509.jpg',open('/20220212235319_1509.jpg','rb'),'image/jpeg'))
]
headers = {
  'Accept-Language': 'en-US',
  'Authorization': 'Bearer yourToken'
}

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

print(response.text)

This works for me.

import requests

url = "https://example.com"
payload={}
files=[
  ('file',('myfile.jpg',open('/path/to/myfile.jpg','rb'),'image/jpeg'))
]

response = requests.request("POST", url, auth=("my_username","my_password"), data=payload, files=files)
print(response.text)

From wechat api doc:

curl -F [email protected] "http://file.api.wechat.com/cgi-bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE"

Translate the command above to python:

import requests
url = 'http://file.api.wechat.com/cgi-bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE'
files = {'media': open('test.jpg', 'rb')}
requests.post(url, files=files)

In case if you were to pass the image as part of JSON along with other attributes, you can use the below snippet.
client.py

import base64
import json                    

import requests

api = 'http://localhost:8080/test'
image_file = 'sample_image.png'

with open(image_file, "rb") as f:
    im_bytes = f.read()        
im_b64 = base64.b64encode(im_bytes).decode("utf8")

headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
  
payload = json.dumps({"image": im_b64, "other_key": "value"})
response = requests.post(api, data=payload, headers=headers)
try:
    data = response.json()     
    print(data)                
except requests.exceptions.RequestException:
    print(response.text)

server.py

import io
import json                    
import base64                  
import logging             
import numpy as np
from PIL import Image

from flask import Flask, request, jsonify, abort

app = Flask(__name__)          
app.logger.setLevel(logging.DEBUG)
  
  
@app.route("/test", methods=['POST'])
def test_method():         
    # print(request.json)      
    if not request.json or 'image' not in request.json: 
        abort(400)
             
    # get the base64 encoded string
    im_b64 = request.json['image']

    # convert it into bytes  
    img_bytes = base64.b64decode(im_b64.encode('utf-8'))

    # convert bytes data to PIL Image object
    img = Image.open(io.BytesIO(img_bytes))

    # PIL image object to numpy array
    img_arr = np.asarray(img)      
    print('img shape', img_arr.shape)

    # process your img_arr here    
    
    # access other keys of json
    # print(request.json['other_key'])

    result_dict = {'output': 'output_key'}
    return result_dict
  
  
def run_server_api():
    app.run(host='0.0.0.0', port=8080)
  
  
if __name__ == "__main__":     
    run_server_api()

import requests

image_file_descriptor = open('test.jpg', 'rb')
# Requests makes it simple to upload Multipart-encoded files 
files = {'media': image_file_descriptor}
url = '...'
requests.post(url, files=files)
image_file_descriptor.close()

Don't forget to close the descriptor, it prevents bugs: Is explicitly closing files important?

Use this snippet

import os
import requests
url = 'http://host:port/endpoint'
with open(path_img, 'rb') as img:
  name_img= os.path.basename(path_img)
  files= {'image': (name_img,img,'multipart/form-data',{'Expires': '0'}) }
  with requests.Session() as s:
    r = s.post(url,files=files)
    print(r.status_code)

For Rest API to upload images from host to host:

import urllib2
import requests

api_host = 'https://host.url.com/upload/'
headers = {'Content-Type' : 'image/jpeg'}
image_url = 'http://image.url.com/sample.jpeg'

img_file = urllib2.urlopen(image_url)

response = requests.post(api_host, data=img_file.read(), headers=headers, verify=False)

You can use option verify set to False to omit SSL verification for HTTPS requests.

I confronted similar issue when I wanted to post image file to a rest API from Python (Not wechat API though). The solution for me was to use 'data' parameter to post the file in binary data instead of 'files'. Requests API reference

data = open('your_image.png','rb').read()
r = requests.post(your_url,data=data)

Hope this works for your case.
