我正在使用standard-redirects-for-cloudfront Lambda@Edge 函数来处理

“内部”从 /foo/ 重定向到 /foo/index.html，“外部”从 /foo/index.html 重定向到 /foo/。

我在提供自定义错误页面时遇到问题。

目前我在我的 S3 存储桶中有对象/404.html（也配置为 S3 静态网站的错误页面，无论如何都不应该请求它，因为它应该是 Cloudfront 的责任）。

在 Cloudfront 中，我将/404.html设置为 404 状态的自定义错误页面。

我应该如何设置它以返回错误页面？

看起来没有返回错误页面，因为 CloudFront 获取自定义错误页面时正在执行上述函数。

为确保在从 S3 存储桶请求自定义错误页面时不执行该函数，可以从未配置 Lambda 函数的不同缓存行为提供自定义错误页面。

例如，可以在没有任何 Lambda 的情况下配置具有路径模式/error-pages/*的缓存行为，并且可以为来自源的 404 状态代码的自定义错误页面设置/error-pages/404.html 。
