AWS S3配置x-amz-website-redirect-location重定向不生效问题

操作流程：

• 在AWS S3中创建存储桶，开启静态网站托管功能
• 上传两个HTML文件到存储桶：
  • page1.html 文件内容：

    This is page1
    

  • page2.html 文件内容：

    This is page2
    

• 在S3管理控制台为page1.html对象添加元数据：x-amz-website-redirect-location = /page2.html

故障现象：
通过Chrome浏览器访问S3静态网站地址时，访问page1未触发重定向，页面仍显示page1原有内容，没有跳转到page2。已对照官方操作指引检索排查相关方案，仍未定位问题。

访问端点用错了，当前使用的是S3 REST API对象端点，不是静态网站托管专属端点，重定向逻辑不会触发。
从curl结果可以直接看到，请求的地址是https://aws-redirect-test.s3.ap-northeast-1.amazonaws.com/page1.html，这个是S3原生的对象访问接口，只会原样返回对象内容和配置的自定义元数据，不会处理x-amz-website-redirect-location对应的重定向规则——这个重定向逻辑只有访问S3静态网站专属端点时才会生效。
S3静态网站端点的域名格式和REST端点有明显区别，以ap-northeast-1区域为例，格式为http://<桶名>.s3-website-ap-northeast-1.amazonaws.com，域名标识段是s3-website，而非REST端点的s3。

• 打开S3控制台，进入对应存储桶的「属性」页面，拉到最底部的「静态网站托管」板块，复制面板中官方给出的静态网站端点地址，不要使用对象详情页提供的原生对象访问URL。
• 用复制的静态网站端点拼接/page1.html路径访问，此时S3会识别对象上的重定向元数据，返回301 Moved Permanently状态码，携带Location: /page2.html响应头，自动完成跳转。
• 静态网站端点默认仅支持HTTP协议，如果需要HTTPS访问，需要在端点前挂载CloudFront分配，配置SSL证书后转发请求到静态网站源站，直接访问静态网站端点的HTTPS地址无法连通。
