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。

fwuensche“答案”是正确的设置CDN;这样做，我删除了maxagesecseconds。

<CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedHeader>Authorization</AllowedHeader>
</CORSRule>

对我来说，不加区域

Const s3 = new aws。S3({apiVersion: '2006-03-01'，区域:'us-west-2'});

我在加载web字体时遇到了类似的问题，当我点击“添加CORS配置”时，在桶属性中，这段代码已经存在了:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedMethod>HEAD</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>Authorization</AllowedHeader>
    </CORSRule>
</CORSConfiguration> 

我只是点击保存，它工作得很好，我的自定义网页字体正在IE和Firefox中加载。我不是这方面的专家，我只是觉得这个也许能帮到你。

这是一种简单的工作方法。

我知道这是一个老问题，但仍然很难找到解决办法。

首先，我用Rails 4、Paperclip 4、CamanJS、Heroku和AWS S3构建了一个项目。

你必须使用crossorigin: "anonymous"参数请求你的图像。

    <img href="your-remote-image.jpg" crossorigin="anonymous"> 

Add your site URL to CORS in AWS S3. Here is a refference from Amazon about that. Pretty much, just go to your bucket, and then select "Properties" from the tabs on the right, open "Permissions tab and then, click on "Edit CORS Configuration". Originally, I had < AllowedOrigin> set to *. Just change that asterisk to your URL, be sure to include options like http:// and https:// in separate lines. I was expecting that the asterisk accepts "All", but apparently we have to be more specific than that.

对我来说是这样的。

我把它写如下:

<?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>

为什么<AllowedHeader>*</AllowedHeader> is working and <AllowedHeader>Authorization</AllowedHeader> not?
