在松弛通道中未打开使用web-hook的松弛模态消息

Question

我使用web-hook在Slack频道中发布了一条模式交互消息，但该消息没有显示在Slack频道中。

Slack文档中有一些关于触发器id的信息，但这些信息非常混乱。

下面是我的JSON有效负载，我正在使用来自Slack的预构建模板，并使用web-hook将消息发送到Slack通道。

Answer 1

你需要一个trigger_id来打开一个模式。基本上，只有当用户说“显示模式！”时，Slack才会让你显示模式！这可以防止开发人员向毫无戒心的用户发送恼人的、不想要的模态。您可以在用户与其中一个应用程序“entry points”交互时获取trigger_id：

1. 快捷方式
2. 斜杠命令
3. 应用程序UI中的交互式元素(如按钮)

当用户与其中一个入口点进行交互时，他们告诉您他们想要查看该模式，因此Slack将向您发送一个带有trigger_id的interaction payload。对于全局快捷方式，该有效负载可能类似于this

{
  "type": "shortcut",
  "token": "XXXXXXXXXXXXX",
  "action_ts": "1581106241.371594",
  "team": {
    "id": "TXXXXXXXX",
    "domain": "shortcuts-test"
  },
  "user": {
    "id": "UXXXXXXXXX",
    "username": "aman",
    "team_id": "TXXXXXXXX"
  },
  "callback_id": "shortcut_create_event",
  "trigger_id": "944799105734.773906753841.38b5894552bdd4a780554ee59d1f3638"
}

所以基本上，你需要首先创建一个，并设置你的应用程序来接收来自Slack的POST请求。

一旦你知道用户想要显示模式，你可以告诉Slack打开模式。创建一个view payload (代码中的附件)，并包含您收到的trigger_id。将此有效负载发送到views.open端点。请注意，您并没有像在代码中那样发送消息有效负载，请记住，trigger_id将在3秒内过期。

var payload = {
  trigger_id: "944799105734.773906753841.38b5894552bdd4a780554ee59d1f3638",
  view: {
    "type": "modal",
    "submit": {
      "type": "plain_text",
      "text": "Submit",
      "emoji": true
    },
    "close": {
      "type": "plain_text",
      "text": "Cancel",
      "emoji": true
    },
    "title": {
      "type": "plain_text",
      "text": "Your accommodation",
      "emoji": true
    },
    "blocks": [
      {
        "type": "section",
        "text": {
          "type": "plain_text",
          "text": "Please choose an option where you'd like to stay from Oct 21 - Oct 23 (2 nights).",
          "emoji": true
        }
      }
    ]
  }
};
