项目中正在使用kindeditor, 版本4.1.10
很多公司的图片会走CDN,需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:

上传按钮是提交到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。
具体实现:(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):

跨域中使用需要修改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()即可无需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有参数s和#号是重复的,很low,在a.com中用到。期望修改掉。

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();
	});

按钮: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参数
	    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传参数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>

其中参数s和#号自己处理下可以只用1个。

以上IE678910火狐、chrome测试通过。苹果浏览器safari测试未通过。

===========================================================
safari下原因:请求redirect.html后iframe的onload调用处理时转为json时出
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"}
如下图的str转json:K.json(str).(kindeditor-all.js 4196-4206行)
bubuko.com,布布扣
bubuko.com,布布扣
应该是请求有问题,临时解决,修改kindeditor-all.js(错误时再尝试下转码)
bubuko.com,布布扣
bubuko.com,布布扣


自己的处理,低级的地方多指正学习。
