Facebook即时文章自定义嵌入;不要提出要求

Facebook Instant Article custom embed doesn't make requests

本文关键字：文章 自定义 Facebook      更新时间：2023-09-26

我正试图将我自己的脚本（它为iframe注入一些内容）嵌入到FB Instant文章中。

它似乎只适用于某些设备（例如iPhone 5s和6s，LG G2），但其他设备（三星设备）似乎没有加载任何内容。

显然，问题在于实际请求脚本的src，但这只是一个假设。（为了演示，我把src改成了angular）。

我尝试使用Facebook建议的工具进行调试：链接

我添加了一个页面示例（仅供参考，如果您将其粘贴到文章编辑器中，它将发出警告）。

注意：当我的代码被直接插入到脚本标记中而没有来自某个来源的请求时，它会按预期运行。

怎么了？为什么FB Instant Articles没有为我的剧本打电话？

谢谢

<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker <a href="http://www.lipsum.com/">including versions of Lorem Ipsum.</a>)</p>

我在Instagram和其他社交嵌入中遇到了同样的问题。通过HTTPS加载脚本为我解决了这个问题。我在Facebook文档中找不到任何关于HTTPS要求的信息。我猜浏览器/webview正在抛出一个通用的混合内容警告。

编辑：更新这些<scripts>：
