SpringBoot editorMD 图片跨域上传问题.

Question

editor配置

##callbakc.html

##后台

##我接受文件的后台都做了跨域的处理，目前是上传请求能到后台且文件存储成功，但是editorMD 还是判断为跨域，

出现错误
image-dialog.js:171 Uncaught DOMException: Blocked a frame with origin "http://localhost:8080" from accessing a cross-origin frame.
at HTMLIFrameElement.uploadIframe.onload (http://localhost:8080/plugins/image-dialog/image-dialog.js:171:129)

    js对应
    var body = (uploadIframe.contentWindow ? uploadIframe.contentWindow : uploadIframe.contentDocument).document.body;
    标红的document.body

Answer 1

在后台代码层加注解@CrossOrigin
例如：

@RestController
@RequestMapping(value = "/api/index")
@CrossOrigin
public class IndexController {

解决跨域问题
