使用 python 在 slack 中创建模态

Question

我正在使用 python 松紧螺栓。 https://api.slack.com/start/building/bolt-python#create

我在链接中创建了示例，并且能够制作主页标签页，但我想从频道中的消息创建模式，而不是主页视图。 我到处寻找一个基本示例，但我无法让任何 MODALS 与我从 slack 自己的文档中学到的东西一起工作。 这是我能找到的唯一示例（在您阅读起始页面后来自 slack 自己的文档）。

这是一个有效的测试示例，但显示的是主页而不是模式：

SLACK_BOT_TOKEN="slackbottokenstring"
SLACK_SIGNING_SECRET="slacksigningsecretstring"

import os
# Use the package we installed
from slack_bolt import App

# Initializes your app with your bot token and signing secret
app = App(
    token = SLACK_BOT_TOKEN,
    signing_secret = SLACK_SIGNING_SECRET
    # token=os.environ.get("SLACK_BOT_TOKEN"),
    # signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
)

# Add functionality here
@app.event("app_home_opened")
def update_home_tab(client, event, logger):
  try:
    # views.publish is the method that your app uses to push a view to the Home tab
    client.views_publish(
      # the user that opened your app's app home
      user_id=event["user"],
      # the view object that appears in the app home
      view={
        "type": "home",
        "callback_id": "home_view",

        # body of the view
        "blocks": [
          {
            "type": "section",
            "text": {
              "type": "mrkdwn",
              "text": "*Welcome to your _App's Home_* :tada:"
            }
          },
          {
            "type": "divider"
          },
          {
            "type": "section",
            "text": {
              "type": "mrkdwn",
              "text": "This button won't do much for now but you can set up a listener for it using the `actions()` method and passing its unique `action_id`. See an example in the `examples` folder within your Bolt app."
            }
          },
          {
            "type": "actions",
            "elements": [
              {
                "type": "button",
                "text": {
                  "type": "plain_text",
                  "text": "Click me!"
                }
              }
            ]
          }
        ]
      }
    )
  
  except Exception as e:
    logger.error(f"Error publishing home tab: {e}")


# Start your app
if __name__ == "__main__":
    app.start(port=int(os.environ.get("PORT", 3000)))

这有效：

但是，如果我尝试将其更改为模态，则会失败：代码：

@app.event("app_home_opened")
def update_home_tab(client, event, logger):
  try:
    # views.publish is the method that your app uses to push a view to the Home tab
    client.views_publish(
      # the user that opened your app's app home
      user_id=event["user"],
      # the view object that appears in the app home
      view={
  "type": "modal",
  "callback_id": "modal-identifier",
  "title": {
    "type": "plain_text",
    "text": "Just a modal"
  },
  "blocks": [
    {
      "type": "section",
      "block_id": "section-identifier",
      "text": {
        "type": "mrkdwn",
        "text": "*Welcome* to ~my~ Block Kit _modal_!"
      },
      "accessory": {
        "type": "button",
        "text": {
          "type": "plain_text",
          "text": "Just a button",
        },
        "action_id": "button-identifier",
      }
    }
  ],
}
    )

错误：

127.0.0.1 - - [14/Aug/2022 15:21:15] "POST /slack/events HTTP/1.1" 200 -
Error publishing home tab: The request to the Slack API failed. (url: https://www.slack.com/api/views.publish)
The server responded with: {'ok': False, 'error': 'invalid_arguments', 'response_metadata': {'messages': ['[ERROR] failed to match all allowed schemas [json-pointer:/view]', '[ERROR] unsupported type: modal [json-pointer:/view/type]']}} 

我正在遵循 json object 中的视图结构设计，就像这里所说的： https://api.slack.com/surfaces/modals/using#composing_views

Answer 1

我知道我必须做什么，但这有点烦人，我想先说一下。 有几个原因可以解释为什么它很烦人。

1. 网站上没有直接的 python 示例，但 slack 确实有 github ，其中显示了模态示例。
2. 专门使用 Modals 不仅仅需要在聊天中制作文本块。 它需要一些称为trigger_id的奇怪东西，您可以通过启动特定响应获得该响应，该响应会导致松弛将 object 发送到您的端点。 问题是没有这样的例子。 如果您正在阅读 slack 的教程，它们只会向您展示如何创建 url 以使事件侦听和响应消息的机器人。 You can make your own url using flask but since I am using the bolt slack module, they wrap there own stuff around flask which makes it hard to make basic decorators for flask. - 换句话说，slack 文档对于模态模型来说非常混乱，并且他们没有任何带有螺栓 python 的模态模型的真实示例。

在业余时间进行了几天的研究之后，我终于能够获得一个可以复制和粘贴此代码的示例。 如果您只是在本地计算机上进行测试，您只需要您可以在环境中设置或作为字符串设置的机器人令牌密钥和签名密钥。

SLACK_BOT_TOKEN="slackbottokenstring"
SLACK_SIGNING_SECRET="slacksigningsecretstring"

import os
# Use the package we installed
from slack_bolt import App
from slack_bolt.adapter.flask import SlackRequestHandler
from flask import Flask, request

flask_app = Flask(__name__)

# Initializes your app with your bot token and signing secret
app = App(
    token = SLACK_BOT_TOKEN,
    signing_secret = SLACK_SIGNING_SECRET
    # token=os.environ.get("SLACK_BOT_TOKEN"),
    # signing_secret=os.environ.get("SLACK_SIGNING_SECRET")
)
handler = SlackRequestHandler(app)

@flask_app.route("/slack/events", methods=["POST"])
def slack_events():
    return handler.handle(request)

@app.shortcut("SearchMessagesID")
def handle_shortcuts(ack, body, logger,client):
    ack()
    logger.info(body)
    print(body)

    res = client.views_open(
        trigger_id=body["trigger_id"],
    view={
  "type": "modal",
  "callback_id": "modal-identifier",
  "title": {
    "type": "plain_text",
    "text": "Just a modal"
  },
  "blocks": [
    {
      "type": "section",
      "block_id": "section-identifier",
      "text": {
        "type": "mrkdwn",
        "text": "*Welcome* to ~my~ Block Kit _modal_!"
      },
      "accessory": {
        "type": "button",
        "text": {
          "type": "plain_text",
          "text": "Just a button",
        },
        "action_id": "button-identifier",
      }
    }
  ],
}
    )

# Start your app
if __name__ == "__main__":
    app.start(port=int(os.environ.get("PORT", 3000)))
