如何在 python 中使用 slackbot？

Question

我正在尝试为我的小组构建一个 slackbot，我尝试了示例代码和其他一些东西，但它没有向小组发送消息。

首先我通过终端尝试

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>

但是 slack 组中没有消息。

我尝试使用此代码：

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}

我没有明白我做错了什么，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

当我使用 php 和 symfony 实现一个 slack 机器人时，我遇到了类似的问题。 正确创建和配置 Slack 应用、bot 和 OAuth 权限并不是那么简单。

如果您需要，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/

另外，我在 PHP 中的代码与解析 Slack 请求并发布到其 API 所需的代码非常相似。

总结，TL；DR：

• 转到https://api.slack.com/apps 并点击“创建新应用”。

• 在此应用配置中，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”。

• 仍在此应用配置中，转到菜单“OAuth & Permissions”并允许范围“chat:write:bot”并复制“OAuth Access Token”的值

• 从您的代码中，使用以前的令牌值调用带有“Authorization”标头的“chat.postMessage”API 方法。

根据网上找到的一些示例构建了这个：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
