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": []
    }
]

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。

首先，激活S3存储桶中的CORS。使用以下代码作为指导:

<CORSConfiguration>
 <CORSRule>
   <AllowedOrigin>http://www.example1.com</AllowedOrigin>

   <AllowedMethod>PUT</AllowedMethod>
   <AllowedMethod>POST</AllowedMethod>
   <AllowedMethod>DELETE</AllowedMethod>

   <AllowedHeader>*</AllowedHeader>
 </CORSRule>
 <CORSRule>
   <AllowedOrigin>http://www.example2.com</AllowedOrigin>

   <AllowedMethod>PUT</AllowedMethod>
   <AllowedMethod>POST</AllowedMethod>
   <AllowedMethod>DELETE</AllowedMethod>

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

2)如果还是不行，请确保在你的img标签中添加一个带“*”值的“crossorigin”。把这个放在你的html文件中:

  let imagenes = document.getElementsByTagName("img");
    for (let i = 0; i < imagenes.length; i++) {
      imagenes[i].setAttribute("crossorigin", "*");

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>

S3现在期望规则是Array Json格式。

你可以在s3桶中找到这个->权限然后->向下滚动->()跨起源资源共享(CORS)

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "GET",
            "HEAD"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": [],
        "MaxAgeSeconds": 3000
    }
]

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。
