有人设法在响应头中添加Access-Control-Allow-Origin吗? 我需要的是这样的东西:

<img src="http://360assets.s3.amazonaws.com/tours/8b16734d-336c-48c7-95c4-3a93fa023a57/1_AU_COM_180212_Areitbahn_Hahnkoplift_Bergstation.tiles/l2_f_0101.jpg" />

这个get请求应该在响应中包含Access-Control-Allow-Origin: *

我的CORS设置桶看起来像这样:

<?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>

正如您所期望的那样,没有Origin响应头。


当前回答

@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 >

其他回答

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。

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.

在最新的S3管理控制台中,当您单击Permissions选项卡上的CORS配置时,它将显示一个默认的示例CORS配置。但是,这个配置实际上并没有激活!您必须首先单击save才能激活CORS。

我花了很长时间才弄明白,希望这能帮大家节省一些时间。

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>

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", "*");
