Slack API invalid_block

Question

我正在构建一个简单的 Slack 机器人，并且正在使用该checkboxes元素。

当我从 API 以 JSON 响应返回以下内容到斜杠命令时，我收到错误failed with the error "invalid_blocks"，但是，当我将其放入block-kit-builder中时，它可以正常工作（包括“发送到 slack”按钮）

当我运行斜杠命令时，有什么想法会失败吗？是否可以从 slack 中看到更详细的错误消息？

Answer 1

在 Block Kit Builder 中，数据是带有blocks键的 JSON。在 Slack API 中，blocks参数只是对象list的类型JSON。

blocks = [
    {
        "text": {
            "text": "Its the list of your blocks",
            "type": "mrkdwn"
        },
        "type": "section"
    }
]
text = 'Alternative data in text'
client.chat_postMessage(channel=channel_id, blocks=blocks, text=text)

在api中，“blocks”参数需要是字符串类型。您是否将其转换为字符串或将其用作 JSON ？ https://api.slack.com/methods/chat.postMessage
