响应带有错误对象的松弛view_submission事件

问题描述 投票:0回答:1

我使用ASP.NET Core 2.1与Slack建立集成这是我的json格式的模态。

{
  "type": "modal",
  "callback_id": "send_sms",
  "title": {
    "type": "plain_text",
    "text": "Send SMS",
    "emoji": false
  },
  "submit": {
    "type": "plain_text",
    "text": "Submit"
  },
  "close": {
    "type": "plain_text",
    "text": "Cancel"
  },
  "blocks": [
    {
      "type": "divider"
    },
    {
      "type": "input",
      "block_id": "phone_number",
      "label": {
        "type": "plain_text",
        "text": "Enter phone number",
        "emoji": false
      },
      "element": {
        "type": "plain_text_input",
        "placeholder": {
          "type": "plain_text",
          "text": "Phone number",
          "emoji": false
        },
        "action_id": "action_phone_number"
      }
    },
    {
      "type": "input",
      "block_id": "message",
      "label": {
        "type": "plain_text",
        "text": "Enter message",
        "emoji": false
      },
      "element": {
        "placeholder": {
          "type": "plain_text",
          "text": "Message",
          "emoji": false
        },
        "action_id": "message",
        "type": "plain_text_input",
        "multiline": true
      }
    }
  ]
}

因此,当用户提交表单时,我的.net核心应用程序会收到一个view_submission事件,如果电话号码的格式无效,我想对此事件做出响应并返回错误。松弛文档说我应该用这样的json对象来响应:

`{
  "response_action": "errors",
  "errors": {
    "phone_number": "Invalid phone number format"
  }
}`

[在调试过程中,我发现我的应用程序实际上确实从文件中加载json,并使用包含该json的字符串进行响应。但是仍然在我的模态上出现此错误enter image description here

控制器方法返回Task>对象,但我不确定它是否正确所以我的问题是:有人知道我应该如何使用.net core响应此松弛事件吗?据我了解,即使我的.net核心应用中出现验证错误,并且我想将错误对象返回到松弛状态,我也应该以状态200 OK进行响应
