javascript - 如何使用 Slack 模态输入的数据发送 channel 消息

Question

我正在尝试构建一个 Slack 应用程序，该应用程序将在填写表单后启用发布 channel 消息。为此，我创建了一个调用模式的斜杠命令。现在我遇到一个问题，如何访问此输入数据并使用它来撰写将发送到所选 channel 的消息。

    app.command('/spotkanie', async ({ ack, body, context }) => {
      // Acknowledge the command request
      await ack();

      try {
        const result = await app.client.views.open({
          token: context.botToken,
          // Pass a valid trigger_id within 3 seconds of receiving it
          trigger_id: body.trigger_id,
          // View payload
          view_id: "view_spotkanie",
          user_id: "user",
          view: {
        "type": "modal",
      "callback_id": "zaplanuj-spotkanie",  
        "title": {
            "type": "plain_text",
            "text": "Zaplanuj spotkanie",
            "emoji": true
        },
        "submit": {
            "type": "plain_text",
            "text": "Wyślij",
            "emoji": true
        },
        "close": {
            "type": "plain_text",
            "text": "Anuluj",

        },

              "type": "plain_text",
              "text": "Wyślij do",

            "element": {

                "placeholder": {
                          "type": "plain_text",
                          "text": "Gdzie wysłać powiadomienie o spotkaniu?",
                          "emoji": true
                    }
            }
          }
        ]

    }
        });
    console.log(result);
      }
      catch (error) {
        console.error(error);
      }
    });

    app.view('zaplanuj-spotkanie', async ({ ack, body, view, context, say }) => {

现在，根据 Slack 说明，这个 app.view 应该可以让我访问输入数据，但我仍然不知道如何使用它。

Answer 1

要从模态接收输入文本，您应该使用 Slack 交互式消息。

// Example of handling a simple view submission
slackInteractions.viewSubmission('simple_modal_callback_id', (payload) => {
  // Log the input elements from the view submission.
  console.log(payload.view.state);

  // The previous value is an object keyed by block_id, which contains objects keyed by action_id,
  // which contains value properties that contain the input data. Let's log one specific value.
  console.log(payload.view.state.my_block_id.my_action_id.value);

  // Validate the inputs (errors is of the shape in https://api.slack.com/surfaces/modals/using#displaying_errors)
  const errors = validate(payload.view.state);

  // Return validation errors if there were errors in the inputs
  if (errors) {
    return errors;
  }

  // Process the submission
  doWork();
});
