问题描述

我正在开发一种休闲机器人.我正在实现通知功能，它将每隔一小时发送一次通知.当前，我在通知中发送普通文本，但是我需要将图像与文本一起发送.可以发送图像吗?

I am developing a bot for slack. I am implementing a notification functionality, where it will send a notification for every one hour. Currently, I am sending normal text in notification, but I need to send an image along with text. Is it possible to send an image?

推荐答案

您可以将图像作为邮件附件的一部分发送.那可以是完整图像或缩略图.

You can send images as part of the attachments of a message. That can be either a full image or a thumbnail.

只需为完整图像或添加 image_url 属性缩略图的href ="https://api.slack.com/docs/message-attachments#thumb_url" rel ="noreferrer"> thumb_url 属性，其中包含指向附件及其图像的URL将显示在您的消息下方.您还可以通过添加多个附件来发送多张图像.

Just add the image_url property for full images or the thumb_url property for a thumbnail image with a url to an image to your attachment and it will be displayed under your message. You can also send multiple images through adding multiple attachments.

示例附件:(基于官方的Slack文档示例)

Example attachment: (based on official Slack documentation example)

{
    "attachments": [
        {
            "fallback": "Required plain-text summary of the attachment.",
            "text": "Optional text that appears within the attachment",
            "image_url": "http://my-website.com/path/to/image.jpg",
            "thumb_url": "http://example.com/path/to/thumb.png"
        }
    ]
}

这适用于所有发送消息的方法，例如API方法，传入的Webhook，对斜杠命令的响应等.

This works with all approaches for sending message, e.g. API method, Incoming webhook, response to slash commands etc.
