javascript - 403(CORS 未启用或未找到此请求的匹配规则。)[VueJs]

Question

我正在使用 HTTP 请求将图像上传到 Azure 存储，当存储帐户的 CORS 为通用时，它对我来说很有效，例如:

allowed origins: *
allowed methods: 7 selected (which all options)
allowed headers: *
exposed headers: *
max age: 0

在我的 Http 请求中(唱 axios):

headers: {
     "Access-Control-Allow-Origin" : "*",
     "Access-Control-Allow-Methods": "*",
     "Access-Control-Allow-Headers": "*",
     "Content-Type": "image/png",
     "x-ms-date": currentDate,
     "x-ms-version": ""2017-11-09"",
     "x-ms-blob-type": "BlockBlob",
}

它与我一起工作并上传了图像，但是当我修改 CORS 以添加一些约束时，它不起作用。例如:

allowed origins: https://XXXXXXXX.blob.core.windows.net/
allowed methods: 7 selected (which all options)
allowed headers: Authorization,x-ms-*
exposed headers: x-ms-meta-*
max age: 3600

在我的 HTTP 请求中(使用 axios):

headers: {
     "Access-Control-Allow-Origin" : "https://XXXXXXXX.blob.core.windows.net/",
     "Access-Control-Allow-Methods": "PUT,GET,PATCH,POST,HEAD,DELETE,MERGE,OPTIONS",
     "Access-Control-Allow-Headers": "Authorization,x-ms-*,content-*",
     "Content-Type": "image/png",
     "x-ms-date": currentDate,
     "x-ms-version": ""2017-11-09"",
     "x-ms-blob-type": "BlockBlob",
}

我遇到两条错误消息:

OPTIONS https://XXXXXXXXXX.blob.core.windows.net/user-avatar/XXXXXXXXXXXXXXXXXXXXXXXX 403 (CORS not enabled or no matching rule found for this request.)

Failed to load https://XXXXXXXXXX.blob.core.windows.net/user-avatar/XXXXXXXXXXXXXXXXXXXXXXXX: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.

我该如何解决这个问题？

Answer 1

更改此行

"Access-Control-Allow-Origin" : "https://XXXXXXXX.blob.core.windows.net/",

至

"Access-Control-Allow-Origin" : "localhost:8080/",

看看CORS - How do 'preflight' an httprequest?
