我尝试了很多方法来解决这个问题，但最后，我还是这么做了

url.replace(/^https:\/\//i, "http://");

我不知道为什么，但这对我很有效。 如果您从s3存储桶中获取图像为“BLOB”，请执行此操作。

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": []
    }
]

对我来说，不加区域

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

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.

上面的大部分答案都没用。我试图上传图像到S3桶使用react-s3，我得到了这个

跨地域请求被阻止

错误。

您所要做的就是在s3 Bucket中添加CORS配置 进入“S3桶->权限-> CORS配置” 然后粘贴下面的内容

<CORSConfiguration>
 <CORSRule>
   <AllowedOrigin>*</AllowedOrigin>

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

   <AllowedHeader>*</AllowedHeader>
 </CORSRule>
 <CORSRule>
   <AllowedOrigin>*</AllowedOrigin>

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

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

将*替换为您的网站url。 参考:AWS CORS设置

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>
