Uncaught DOMException: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Blocked a frame with origin "http://127.0.0.1:8079" from accessing a cross-origin frame.
at HTMLIFrameElement.<anonymous> (http://127.0.0.1:8079/static/oss/ajaxupload.3.9.js:573:33)
使用AjaxUploadFile插件出错：代码
var doc = iframe.contentDocument ? iframe.contentDocument : window.frames[iframe.id].document;
一样的请求地址,域名和端口后都一致,还提示 accessing a cross-origin
分析代码：
/** * 上传单个文件到OSS * @param request * @param response * @throws Exception */ public static void uploadFile(MultipartHttpServletRequest request, HttpServletResponse response) throws Exception { JSONObject json = new JSONObject(); MultipartFile file = request.getFile("img"); byte[] data = file.getBytes(); OssResponse ossResponse = ossUpload(data, file.getOriginalFilename()); if (ossResponse != null) { json.put("url",ossResponse.getOssImgUrl()); json.put("success","true"); } else { json.put("success", false); } String html = "<!DOCTYPE html>"+ "<html>"+ "<head>"+ "<script type="text/javascript">"+ // "document.domain = '127.0.0.1';"+ "</script>"+ "</head>"+ "<body>"+ json.toString()+ "</body>"+ "</html>"; PrintWriter writer = response.getWriter(); writer.print(html); writer.flush(); writer.close(); }
后台代码输出结果：
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
document.domain = '127.0.0.1';
</script>
</head>
<body>
{"success":"true","url":"//****44f64df0f06b40369a8cc7531ce77533.jpg"}
</body>
</html>
解决方法：去掉 "document.domain = '127.0.0.1';" 即可
