AWS中使用CloudFront分发位于S3中的静态网站

这是其中一种方法，可有变化

假设主页为index.html

还要准备一个证书，要覆盖子域名（AWS Certificate Manager->Certificates）

1、S3->Create bucket->Bucket name(myweb)->Create bucket

2、S3->Buckets->myweb->Upload->Add files Add folder

3、CloudFront->Distributions->Create->Origin domain(myweb.s3.amazonows.com)->Name(myweb)->Origin access(Origin access control settings (recommended))->Origin access control->Create new OAC->复制到S3->Alternate domain name (CNAME) - optional->Add item->(www.youweb.com)->Custom SSL certificate - optional(提前准备好证书)->Create distribution

4、Amazon S3->Buckets->myweb->Permissions->Bucket policy->Edit->粘贴到S3

5、Route 53->Hosted zones->配置域名记录

6、问题：www.youweb.com不能访问，只能访问www.youweb.com/index.html

6.1、办法,CloudFront Functions：

6.2、CloudFront->Functions->Create function->Name(index)->Create function

function handler(event) {
    var request = event.request;

    // 如果请求路径是根路径（/），重写为 /index.html
    if (request.uri === '/') {
        request.uri = '/index.html';
    }

    return request;
}

6.3、CloudFront->Functions->index->Publish->Publish function

6.4、CloudFront->Distributions->myweb->Behaviors->Edit->Function associations - optional->Viewer request->Function type->CloudFront Functions->Function ARN / Name(index)
