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": []
    }
]

我也有类似的问题，从S3加载3D模型到javascript 3D查看器(3D HOP)，但奇怪的是，只有特定的文件类型(.nxs)。

为我修复它的是在CORS配置中将AllowedHeader从默认授权更改为*:

<?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>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>

我尝试了上面所有的答案，没有一个工作。实际上，我们需要从上述答案中总结出3个步骤来实现它:

As suggested by Flavio; add CORS configuration on your bucket: <CORSConfiguration> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> </CORSRule> </CORSConfiguration> On the image; mention crossorigin: <img href="abc.jpg" crossorigin="anonymous"> Are you using a CDN? If everything works fine connecting to origin server but NOT via CDN; it means you need some setting on your CDN like accept CORS headers. Exact setting depends on which CDN you are using.

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.

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。

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。
