I've set up a webhook in a chat room in my Google Hangouts Chat.
I can successfully run their example code, which generates a message from the bot associated with the webhook in the chat:
from httplib2 import Http from json import dumps # # Hangouts Chat incoming webhook quickstart # def main(): url = '<INCOMING-WEBHOOK-URL>' bot_message = { 'text' : 'Hello from Python script!'} message_headers = { 'Content-Type': 'application/json; charset=UTF-8'} http_obj = Http() response = http_obj.request( uri=url, method='POST', headers=message_headers, body=dumps(bot_message), ) print(response) if __name__ == '__main__': main() However, I wish to send this message using standard library packages, such as urllib.
But when I use urllib and run the below code, I get an urllib.error.HTTPError: HTTP Error 400: Bad Request. Why am I getting this error?
import json import urllib.parse import urllib.request def main(): # python 3.6 url = '<INCOMING-WEBHOOK-URL>' bot_message = {'text': 'Hello from Python script!'} message_headers = {'Content-Type': 'application/json; charset=UTF-8'} url_encoded = urllib.parse.urlencode(bot_message) byte_encoded = url_encoded.encode('utf-8') req = urllib.request.Request(url=url, data=byte_encoded, headers=message_headers) response = urllib.request.urlopen(req) print(response.read()) if __name__ == '__main__': main()
