个人选择:rtsp/webrtc 推流。hls 看

@tongqe
场景一:我要开发一个机器人,接受用户的命令或消息并反馈。
discord -- 这是 discord 支持的可显示在界面上的消息组件:
https://discord.com/developers/docs/interactions/message-components
里面包含多种互动组件和前端常用元素,并且都可以自定义样式。
钉钉 -- 钉钉支持的消息类型:
https://open.dingtalk.com/document/orgapp/types-of-messages-sent-by-robots?spm=ding_open_doc.document.0.0.23881563V9gXMD
按钮(固定样式)、文本图片视频显示。没了。
而且里面列出的消息类型常常会给各种限制,譬如虽然他把 markdown 列里面但并不是所有时候你发个 markdown 回去都能渲染。(这一点腾讯更加 sb, 它甚至 markdown 都不支持)
更不要说钉钉本身对 markdown 的显示支持也是一坨 x.

场景二:我想写个钉钉应用,自动生成日志
https://open.dingtalk.com/document/orgapp/create-a-log
居然只支持纯文本,别说自定义组件了,甚至它自带的组件一个都不让用,譬如日期选择什么的。
钉钉开发者是觉着自己那些组件写的太好不舍得让人用还是太菜不会写这样的接口?
对比 discord 和 telegram, 要啥给啥,前端库丰富无比。

...

例子多到根本列举不过来,如果你真的亲手在这些平台开发过,我相信你不会说出「我看了下 discord 和 telegram 的,和国内的微信和钉钉差不多啊」这种话。我姑且以善意来回复你的疑问。要是这样你还要继续觉得差不多,我只能认为你是为杠而杠了,那你说得对。
@rookiemaster 你看到「锟斤拷」不就很明显了吗,
必然是你浏览器解析用的是 gbk, 而发上来的是 utf-8 字节。
并且这串 utf-8 同样是乱码,因为有占位符。
所以推测是你哪里多了一步 把 gbk 转成了 utf-8 发给了浏览器
没用过他们家开放平台吧?
但凡尝试过在阿里平台开发过第三方工具,譬如钉钉机器人,企业应用之类的,
就绝不会对「阿里根本没技术基因」这个事实有任何怀疑
腾讯也差不多
