iview Upload组件如何实现跨域文件上传？

Question

iview upload 组件上传

问题描述

其他接口都没有问题，服务器端已经设置了跨域header 并且 其他ajax 请求接口都运行正常，唯独upload 组件文件上传会提示跨域问题

相关代码 错误提示

Access to XMLHttpRequest at 'http://149.60.61.206/api/v1/u...' from origin 'http://localhost:8081' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.

代码

 <Upload
       type="drag"
       name="imgs"
       :action="uploadUri"
       :on-success="handleUploadSuccess"
       :with-credentials="true"
       :headers=headers
       :format="['jpg','jpeg','png','gif']"
       >
    <div style="padding: 20px 0">
         <Icon type="ios-cloud-upload" size="52" style="color: #3399ff"></Icon>
         <p>点击或者拖拽上传</p>
    </div>
 </Upload>

 uploadUri:this.$baseUri+"api/v1/uploader/imageUpload/",
 headers:{'Access-Control-Allow-Origin':'*'},

Answer 1

因为你设置这个为true，他就会携带cookie凭证信息
对于附带身份凭证的请求，服务器不得设置 Access-Control-Allow-Origin 的值为“”。这是因为请求的首部中携带了 Cookie 信息，如果 Access-Control-Allow-Origin 的值为“”，请求将会失败。
也就是说Access-Control-Allow-Credentials设置为true的情况下
Access-Control-Allow-Origin不能设置为*
