I'm trying to call a post rest API using python requests library. I'm able to get a proper response when I request using postman. When I tried to call it using python request library I get an internal server error.

import requests

url = "http://192.188.9.146:9886/getcontext/"

payload = "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"project\"\r\n\r\ndaynight\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"file\"; filename=\"D:\\Downloads\\GTA.Imaging.Services\\GTA.Imaging.Services.Wrapper.TestApp\\PatternMatchingdata\\Go_To_Setting_Screen.jpg\"\r\nContent-Type: image/jpeg\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--"
headers = {
    'content-type': "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW",
    'cache-control': "no-cache",
    'Postman-Token': "79668e4b-305b-404e-904f-92fc71a12f9f"
    }

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

print(response.text)

this gives me error as below 

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request.  Either the server is overloaded or there is an error in the application.</p>

When I use the postman client app I get output with the expected response Postman client what am I doing wrong? Any guidance will be very helpful thanks.

Remove the payload parameter and add files. Refer to requests documentation which explains this option of requests.request function.

import requests

url = "http://192.188.9.146:9886/getcontext/"

files = {'file': open('PATH_TO_FILE\Go_To_Setting_Screen.jpg','rb')}
data  = {'project': 'daynight'}

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

print(response.text)
