S3现在要求它以Javascript对象符号格式出现。

[
 {
    "AllowedHeaders": [
        "*"
    ],
    "AllowedMethods": [
        "GET",
        "HEAD"
    ],
    "AllowedOrigins": [
        "*"
    ],
    "ExposeHeaders": []
 }
]

我建议根据您的需求更改AllowedOrigins和AllowedMethods。

@jordanstephens在评论中说过，但它有点丢失了，对我来说真的很容易修复。

我简单地添加HEAD方法并单击保存，它开始工作。

< CORSConfiguration > < CORSRule > * < AllowedOrigin > < / AllowedOrigin > < AllowedMethod > < / AllowedMethod弄> < AllowedMethod > < / AllowedMethod > <头!添加这个-> < 3000 MaxAgeSeconds > < / MaxAgeSeconds > < AllowedHeader > Authorization < / AllowedHeader > < / CORSRule > < / CORSConfiguration >

下面是配置，它很好地为我工作。我希望这将有助于解决您在AWS S3上的问题。

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>PUT</AllowedMethod>
    <AllowedMethod>POST</AllowedMethod>
    <AllowedMethod>DELETE</AllowedMethod>
    <ExposeHeader>ETag</ExposeHeader>
    <AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>

公认的答案是可行的，但如果直接访问资源，似乎就不存在跨源头。如果您正在使用cloudfront，这将导致cloudfront缓存没有标头的版本。当你转到一个不同的url来加载这个资源时，你会遇到这个跨源问题。

在我的例子中，我用下面的配置来解决它 首先，进入权限，然后进入跨源资源共享(CORS) 然后点击编辑并粘贴下面的代码…

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE"
        ],
        "AllowedOrigins": [
            "http://www.example1.com"
        ],
        "ExposeHeaders": []
    },
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE"
        ],
        "AllowedOrigins": [
            "http://www.example2.com"
        ],
        "ExposeHeaders": []
    },
    {
        "AllowedHeaders": [],
        "AllowedMethods": [
            "GET"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": []
    }
]

Set CORS configuration in Permissions settings for you S3 bucket <?xml version="1.0" encoding="UTF-8"?> <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <MaxAgeSeconds>3000</MaxAgeSeconds> <AllowedHeader>Authorization</AllowedHeader> </CORSRule> </CORSConfiguration> S3 adds CORS headers only when http request has the Origin header. CloudFront does not forward Origin header by default You need to whitelist Origin header in Behavior settings for your CloudFront Distribution.
