项目中正在使用kindeditor, 版本号4.1.10
非常多公司的图片会走CDN,须要单独的一台图片上传服务如:(upload.268xue.com)
kindeditor上传图片的简单内部流程:
上传button是提交到iframe。生成1个form和1个iframe,form提交到(arget)iframe
iframe的onload方法获取返回的值。然后调用配置回调方法afterUpload/afterError。
详细实现:(在a.com选中图片,上传用upload.268xue.com,返回上传的结果给a.com。我的项目springmvc):
跨域中使用须要改动2个地方:1.上传后的返回方式,2回调的页面处理。
1.upload.268xue.com的上传方法:
@RequestMapping(value = "/upload", method = RequestMethod.POST) public String upload(HttpServletRequest request, HttpServletResponse response) { try { String referer = request.getHeader("referer"); Pattern p = Pattern.compile("([a-z]*:(//[^/?#]+)?)?", Pattern.CASE_INSENSITIVE); Matcher mathcer = p.matcher(referer); if (mathcer.find()) { String callBackPath = mathcer.group();// 请求来源a.com MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request; MultipartFile imgFile = multipartRequest.getFile("fileupload");//k4中fileupload //JsonObject json =自己的处理imgFile // 同域时直接返回json.toString()就可以无需redirect String url = "redirect:" + callBackPath + "/kindeditor/plugins/image/redirect.html?s=" + json.toString() + "#" + json.toString(); logger.info(String.format("upload success url:%s", url)); return url; } else { logger.info("upload referer not find"); } } catch (Exception e) { logger.error("upload error", e); } return null; }
上传自己实现。重点是返回,我的打印结果:
upload success url:http://a.com/kindeditor/plugins/image/redirect.html? s={"error":0,"url":"http://upload.268xue.com/upload/sns/temp/20140510/1399706737140139370.jpg"}#{"error":0,"url":"http://upload.268xue.com/upload/sns/temp/20140510/1399706737140139370.jpg"}
redirect有參数s和#号是反复的,非常low,在a.com中用到。期望改动掉。
2.a.com中编辑器的初始化:
var uploadbutton = KindEditor.uploadbutton({ button : KindEditor("fileupload")[0], fieldName : "fileupload", url : "http://upload.268xue.com/upload", afterUpload : function(data) { if (data.error == 0) { //data.url 处理 } else { alert("error"); } }, afterError : function(str) { //alert(‘error: ‘ + str); } }); uploadbutton.fileBox.change(function(e) { uploadbutton.submit(); });
button:fileupload。没有特殊的地方。
3.a.com中kindeditor\plugins\image\redirect.html内容:
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>ie shit shit</title> <script type="text/javascript"> //获取url參数 function getParameter(val) { var uri = window.location.search; var re = new RegExp("" + val + "=([^&? ]*)", "ig"); return ((uri.match(re)) ? (uri.match(re)[0].substr(val.length + 1)) : null); } var upload_callback = function(){ var data=getParameter("s"); var location_hash=location.hash; //ie6取不到hash?? ?用那个方式取?暂使用url传參数s if(location_hash!=null && location_hash!="" && location_hash){ var data = location.hash ? location.hash.substring(1) : ‘‘; document.getElementsByTagName("body")[0].innerHTML = ‘<pre>‘ + data + ‘</pre>‘; }else{ var data=getParameter("s"); document.getElementsByTagName("body")[0].innerHTML = ‘<pre>‘ + data + ‘</pre>‘; } }; </script> </head> <body onload="upload_callback();"> </body> </html>
当中參数s和#号自己处理下能够仅仅用1个。
以上IE6、7、8、9、10、火狐、chrome測试通过。苹果浏览器safari測试未通过。
===========================================================
safari下原因:请求redirect.html后iframe的onload调用处理时转为json时出错:
如:http://a.com/kindeditor/plugins/image/redirect.html? s=%7B%22error%22:0,%22url%22:%22/upload/demo_web/temp/20140510/1399698690364609649.jpg%22%7D#%7B%22error%22:0,%22url%22:%22/upload/demo_web/temp/20140510/1399698690364609649.jpg%22%7D
处理后结果:%7B%22error%22:0,%22url%22:%22/upload/demo_web/temp/20140510/1399698690364609649.jpg%22%7D
转为json时出错。应该格式为:{"error":0,"url":"/upload/demo_web/temp/20140510/1399698690364609649.jpg"}
例如以下图的str转json:K.json(str).(kindeditor-all.js 4196-4206行)
应该是请求有问题,暂时解决,改动kindeditor-all.js(错误时再尝试下转码)
自己的处理,低级的地方多指正学习。
