我为默认欢迎意图创建了两个答案。

一个是默认的，另一个是显示在 Slack 中的文本响应，另一个使用 Slack 作为我的机器人的通道，单击“添加响应”开始使用 Dialogflows UI 为 Slack 创建响应。

第二个如下，:

                    "value": "click_me_123"
                }
            ]
        }
    ]
}

当打招呼时，它应该给出类似下图的内容：

但是，如果在集成中启动测试后显示第一条消息，则第二条消息永远不会显示，即使在右侧的小对话框中也是如此。

我认为问题是我需要公开机器人，因为似乎要使用丰富的消息，我们必须复制 Dialogflow 给出的“事件请求 URL”值并将其粘贴到交互式的“请求 URL”字段中我的 Slack 应用程序设置的消息部分。但机器人甚至不检索默认消息。

我实施机器人所遵循的步骤

• 在 Slack 应用程序中，转到“机器人用户”部分，然后单击“添加机器人用户”按钮。
• 在 Slack 应用程序的“基本信息”部分中，复制“客户端 ID”、“客户端密钥”和“验证令牌”并将其值粘贴到下面的相应字段中。
• 启动机器人。
• 复制下面的“OAuth URL”值，并将其粘贴到 Slack 应用设置的“OAuth 和权限”部分中的“重定向 URL”字段中。保存网址。
• 从下面的字段中复制事件请求 URL，并将其粘贴到 Slack 应用程序的“事件订阅”部分中的请求 URL。
• 在“事件订阅”部分启用事件。
• 在“订阅机器人事件”部分中选择必要的事件，例如 message.im、message.group、message.channel、im_created。这些事件将定义您的机器人将对哪些消息类型（直接消息、渠道内消息等）做出反应。保存更改。我选择了message.im、message.groups、message.channels、im_created
• 在 Slack 应用程序设置中，转到“管理分发”，然后使用“添加到 Slack”按钮将机器人添加到您的 Slack 团队（那里有问题）

为了能够使用自定义负载发送所需的响应，您应该首先添加 Dialogflow 向 slack 发送请求所需的格式。

{
  "slack": {
    "text": "Testing custom payloads",
    "attachments": []
  }
}

在附件中，添加块格式，然后它应该以 Slack 方式将消息发送到您的机器人。

最终消息如下所示：

{
  "slack": {
    "text": "",
    "attachments": [{
    "blocks": [
        {
            "type": "section",
