This article is to share with you about how to use Python simulation to send Slack messages, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

There is a seemingly simple small demand, but it is still a bit difficult for a novice to start Python. Although others also have written code, they just don't want to move other people's code directly. They just don't want to move other people's code directly. When they don't know how to do it, they can't help it. They just want to toss about themselves, and others can write it, which means there must be relevant articles in some places, so don't be afraid to toss about.

1 some links related to Slack

Python slackclient

API Methods

Slack Token

2 how to code the function

Write code, as long as it is about the platform, first search the official website of the platform for relevant api documents and so on.

Secondly, search github to see if there are official open source modules or third-party modules.

Here's what you need, Google.

3 find out how to use 3.1 to simulate method requests in browsers

Here is a reference article

Poster download address of Firefox

3.2 write your own code

Use python to send a message to the channel specified by slack

From slackclient import SlackClientslack_token = os.environ ["SLACK_API_TOKEN"] sc = SlackClient (slack_token) sc.api_call ("chat.postMessage", channel= "C0XXXXXX", text= "Hello from Python!: tada:")

Api_call is a calling interface encapsulated in the module. The function of this interface is that you use a browser to simulate the execution of the post request. It encapsulates the dots that you want to implement the post request in the browser into a black box. Just fill in the parameters according to the format.

The method of sending messages by chat.postMessage

Channel specifies the channel to which the message is to be sent

Text what you want to send

Is it clear at a glance, for example, if I want to get a list of all the channel in workspace, what can I do?

Should we first find the method of getting the list in API Methods?

You can use the above code this time, and change the method of getting the channel list.

As to what the returned object is, you can check it through Type to facilitate the next step.

From slackclient import SlackClient# import requestsimport jsonslack_token= "# do not show you" sc= SlackClient (slack_token) resp = sc.api_call ("channels.list")

Learning is the method, the rest of you have to study hard, to gain something, to share a code written by yourself, although rubbish, but can still run, in the continuous growth, I think I will see what bug at a glance

The above functions are mainly to filter out the monitoring alarms sent to the outlook mailbox and send them to the channel of Slack.
