Python Requests - Unable to send image in payload

Question

I have created an API test using the Python library Requests. I have a problem when i try to create a new product. The product payload contains an image. See the Postman POST request:-

I am trying to send an image as part of a JSON payload. See my code below:-

import requests
import json
import base64
from Utilities.resources import *
from Utilities.payloads import *
from Utilities.configurations import *

config = getConfig()

login_user_url = config['API']['productionUrl'] + ApiResources.userLogin
create_product_url = 'https://eshop-backend-101.herokuapp.com/api/v1/products'

print(create_product_url)

### Create a new product ###

## First get a user token - Login and get token
login_response = requests.post(login_user_url, json=userPayload(), headers=headerPayload())
get_login_json_response = login_response.json()
token = get_login_json_response['token']

## Use token to create product
print("CREATE A PRODUCT")

## https://stackoverflow.com/questions/29104107/upload-image-using-post-form-data-in-python-requests
image_file = "D:\\My Training Courses\\Python APUI Testing - Requests\\images\\testImage.jpg"

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

headerWithBearerTokenWithFormDataPayload = {
                'Content-Type': 'multipart/form-data; boundary=<calculated when request is sent>',
                'Authorization': 'Bearer ' + token
        }

bodyPayload = {
                "name": "Product API Test",
                "description": "Product API Test description",
                "richDescription": "Product API Test rich description",
                "image": im_b64,
                "brand": "Product API Test brand",
                "price": 300,
                "category": "5f15d54cf3a046427a1c26e3",
                "countInStock": 10,
                "rating": 4,
                "numReviews": 22,
                "isFeatured": True
        }

## create_product_response = requests.post(create_product_url, json=newProductPayload(im_b64), headers=headerWithBearerTokenPayload(token))
create_product_response = requests.post(create_product_url, json=bodyPayload, headers=headerWithBearerTokenWithFormDataPayload)
print(create_product_response)

I am getting the following error:-

Your payload should contain the data of the image file, or in whatever format that API is expecting it [could be base64 string]. But your exception is related to failed to make secure connection to the api url. First you should try to call any simple API and establish that you are able to make API calls to that url. — Anand Sowmithiran, Jan 23 '22 at 16:47
did you try some kind of encoding? like base64 as mentioned above — rikyeah, Jan 23 '22 at 16:47
I tried using 64 encoding. I have added my code to the bottom of the description above. — ED209, Jan 23 '22 at 17:03
I have rewritten the description section of the problem I am having — ED209, Jan 23 '22 at 17:25

According to the documentation of requests you need to pass a dictionary as a json parameter, not a string. Same with headers parameter. So remove json.dumps from

bodyPayload = json.dumps(
        {
                "name": "Product API Test",
                "description": "Product API Test description",
                "richDescription": "Product API Test rich description",
                "image": im_b64,
                "brand": "Product API Test brand",
                "price": 300,
                "category": "5f15d54cf3a046427a1c26e3",
                "countInStock": 10,
                "rating": 4,
                "numReviews": 22,
                "isFeatured": True
        }
)

I removed the 'json.dumps(' sections. But I am now getting a new error. See above updated issue section. — ED209, Jan 23 '22 at 20:26
