KeyError urllib

[DavidFernandez]

Hello,

I'm trying to run a command by url and I get the following error code: KeyError: "text"

Here is my python function

with web.urlopen ('http://{0}:{1}/webapi/entry.cgi?api=SYNO.Chat.External&method=incoming&version={2}&token={3}&payload={"text":"Test message.\nDavid fait un test API"}'.format(self.ip,self.port,self.apiversion,self.token)) as url:

Here is the error message I receive:
with web.urlopen ('http://{0}:{1}/webapi/entry.cgi?api=SYNO.Chat.External&method=incoming&version={2}&token={3}&payload={"text":"Test message.\nDavid fait un test API"}'.format(self.ip,self.port,self.apiversion,self.token)) as url:
KeyError: "text"

Yet when I take the url in a web browser it works:
http://*******:*****/webapi/entry.cgi?api=SYNO.Chat.External&method=incoming&version=2&token="***************"&payload={"text":"Test message.\nDavid fait un test API"}

Can you tell me why python considers that the "text" key is in error and how I can solve this problem.

Thank you

Do you want that text bit to be part of the text formatting? If so, you need a text= parameter in the format method call. If not, you need to double the braces around that section starting with "text" ({{ and }}, this escapes them in terms of the format method call).

Should not be using urllib,but Requests.
Send payload in Post,will not work with a dictionary in a url address.
If doing all in a url address have to be in format as param1=value1&param2=value2.
Example:

>>> import requests
>>> 
>>> ip = '111.222.333'
>>> port = 20
>>> apiversion = 99
>>> payload = dict(ip=ip, port=port, apiversion=apiversion)
>>> payload
{'apiversion': 99, 'ip': '111.222.333', 'port': 20}
>>> r = requests.post('http://httpbin.org/post', json=payload)
>>> r.status_code
200

>>> r.json()
{'args': {},
 'data': '{"ip": "111.222.333", "port": 20, "apiversion": 99}',
 'files': {},
 'form': {},
 'headers': {'Accept': '*/*',
             'Accept-Encoding': 'gzip, deflate',
             'Connection': 'close',
             'Content-Length': '51',
             'Content-Type': 'application/json',
             'Host': 'httpbin.org',
             'User-Agent': 'python-requests/2.19.1'},
 'json': {'apiversion': 99, 'ip': '111.222.333', 'port': 20},
 'origin': '83.143.86.74',[]}
 'url': 'http://httpbin.org/post'}

>>> r.json()['json']['port']
20

Hi snippsat,

This code is not work.

My URL link remains unique until payload

http://"IP":"PORT"/webapi/entry.cgi?api=SYNO.Chat.External&method=incoming&version=2&token="TOKENKEY"&payload={"text":"Test message.\nDavid fait un test API"}

I want to make dynamic only the values ​​behind "text":

Can you tell me how I can do to use it with urllib and json.

Thank you
