Language: Python 2.7
Hello all. I found a really helpful script here: Python to Slack Web Hook
that shows how to send messages to a Slack web hook.
import json
import requests
# Set the webhook_url to the one provided by Slack when you create the webhook at https://my.slack.com/services/new/incoming-webhook/
webhook_url = 'https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX'
slack_data = {"text": "<https://alert-system.com/alerts/1234|Click here> for details!"}
response = requests.post(
webhook_url, data=json.dumps(slack_data),
headers={'Content-Type': 'application/json'}
)
if response.status_code != 200:
raise ValueError(
'Request to slack returned an error %s, the response is:\n%s'
% (response.status_code, response.text)
)
It works flawlessly when I run .py file.
Now, I have a file that has many lines of messages that I want to send to Slack. I have it formatted correctly already in the file, no spaces etc.. It's just a matter of grabbing it and passing it so slack_data = line1 etc..
So, I modify the file with something like this:
with open('export.txt', 'r') as e:
for line in e:
slack_data = line
Now if I do a print slack_data right after that, the information returns on the screen exactly as it should be, so I'm thinking it's good. I haven't began to get it working for each line yet, because it's not even working on the first line.
I get an invalid payload 400 when I run it.
EDIT: Slack support said the what they were receiving has escape characters inserted into for some reason.
"{\"text\": \"<https://alert-system.com/alerts/1234|Click here> for details!"}\n"
Any direction or assistance is appreciated.
Thanks!!
Since I already had the data preformatted in the file as JSON already, it was just a matter of removing json.dumps out of the code.
OLD:
#response = requests.post(webhook_url, data=json.dumps(slack_data), headers={'Content-Type': 'application/json'})
NEW:
response = requests.post(webhook_url, data=slack_data, headers={'Content-Type': 'application/json'})
Once I did that, everything worked like a charm.
