python - Slack 发送附件返回 500 错误

问题描述

我正在尝试将附件发送到 Slack 网络挂钩。

我遵循了 API 文档，可以发送一条简单的消息。当我尝试发送附件时收到 500 错误，我认为我的有效负载存在问题，但我终生无法解决。

如何让附件成功发布？

import slackweb

slack = slackweb.Slack(url='WEB HOOK URL HERE')

slack.notify(text="Maguro is a sushi")

attachments = []
attachment = {
    "attachments": [
        {
            "fallback": "Required plain-text summary of the attachment.",
            "color": "#36a64f",
            "pretext": "Optional text that appears above the attachment block",
            "author_name": "Bobby Tables",
            "author_link": "http://flickr.com/bobby/",
            "author_icon": "http://flickr.com/icons/bobby.jpg",
            "title": "Slack API Documentation",
            "title_link": "https://api.slack.com/",
            "text": "Optional text that appears within the attachment",
            "fields": [
                {
                    "title": "Priority",
                    "value": "High",
                    "short": False
                }
            ],
            "image_url": "http://my-website.com/path/to/image.jpg",
            "thumb_url": "http://example.com/path/to/thumb.png",
            "footer": "Slack API",
            "footer_icon": "https://platform.slack-edge.com/img/default_application_icon.png",
            "ts": 123456789
        }
    ]
}

attachments.append(attachment)
slack.notify(attachments=attachments)

解决方案

您在带有附件的 Slack 消息中缺少两个必填字段：text和channel. 您还需要将该short字段的值小写为false.

在 Slack 的消息测试器中查看更正的消息：

{
    "text": "You need this field",
    "channel": "C########",
    "attachments": [
        {
            "fallback": "Required plain-text summary of the attachment.",
            "color": "#36a64f",
            "pretext": "Optional text that appears above the attachment block",
            "author_name": "Bobby Tables",
            "author_link": "http://flickr.com/bobby/",
            "author_icon": "http://flickr.com/icons/bobby.jpg",
            "title": "Slack API Documentation",
            "title_link": "https://api.slack.com/",
            "text": "Optional text that appears within the attachment",
            "fields": [
                {
                    "title": "Priority",
                    "value": "High",
                    "short": false
                }
            ],
            "image_url": "http://my-website.com/path/to/image.jpg",
            "thumb_url": "http://example.com/path/to/thumb.png",
            "footer": "Slack API",
            "footer_icon": "https://platform.slack-edge.com/img/default_application_icon.png",
            "ts": 123456789
        }
    ]
}

创建一个包含这两个字段和您的attachments变量的 JSON 结构，您应该一切顺利。
