如何在python中使用slackbot？

Question

我正在尝试为我的小组建立一个slackbot，我尝试了样本代码和其他一些东西，但它不发送消息给小组。

首先，我尝试了通过终端

export SLACK_API_TOKEN="my_token_id"

然后

from slackclient import SlackClient
import os

slack_token = os.environ["SLACK_API_TOKEN"]
sc = SlackClient(slack_token)

sc.api_call(
  "chat.postMessage",
  channel="#random",
  text="Hello from Python! :tada:",
  thread_ts="283.5127(dummy_id)",
  reply_broadcast=False
)

print(sc)

#<slackclient.client.SlackClient object at 0x109b77ba8>

但在松弛组中没有消息。

我尝试使用以下代码：

from slackclient import SlackClient
import os
slack_token = os.environ['SLACK_API_TOKEN']
sc = SlackClient(slack_token)
print(sc.api_call("channels.list"))

它的重新调整：

{'error': 'invalid_auth', 'ok': False}

我没有得到我做错了什么，访问令牌是正确的，我想通过机器人发布一些消息，那么我如何在slack上创建一个机器人，并使用该机器人我可以通过python发送消息？

Answer 1

当我用php & symfony实现一个slack bot时，我也遇到了类似的问题。正确地创建和配置松弛的应用程序、机器人和OAuth权限并不那么简单。

如果你需要的话，我在这篇博文中解释了所有这些配置：https://blog.eleven-labs.com/en/en/replace-erp-by-slack-bot-with-dialogflow-and-symfony/

此外，我用PHP编写的代码与解析Slack请求和post到其API所需的代码非常相似。

摘要，TL;DR：

• 转到https://api.slack.com/apps并单击“”创建新应用程序“”。
• 在此应用程序配置中，转到左侧菜单“”机器人用户“”或从“”基本信息“”>“”添加特性和功能“”>“”机器人“”。
• 仍在此应用程序配置中，转到“”OAuth&Permissions“”菜单并允许范围“”chat:write:bot“”，从代码中复制“”OAuth Access token“”的值“”
• “”，使用以前的令牌值调用带有“”Authorization“”标头的“”chat.postMessage“”API方法。<代码>H210<代码>F211

这是从网络上找到的一些示例构建的：liza daly - brobot : github.com和How to Build Your First Slack Bot with Python : fullstackpython.com

当然不是最好的实现，但它可以作为(我认为)的适当答案
