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

这个配置为我解决了问题:

<?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>
    <AllowedMethod>HEAD</AllowedMethod>
    <MaxAgeSeconds>3000</MaxAgeSeconds>
    <ExposeHeader>ETag</ExposeHeader>
    <AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>

其他回答

对我来说,不加区域

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

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>

@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 >

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", "*");

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。
