js下载文件

遇到下载MP4文件、text文件的情况 浏览器直接打开了 解决方案

js

function getDownLoadUrl(url){$.ajax({type : "post",dataType : "json",url : "vod-info!getDownLoadurl.htm",data : {url: url,},async : false,success : function(data) {if (data.success) {window.location.href=data.url;}}});}

java代码

public void getDownLoadurl(){String url = this.getPara("url");Map<String, Object> resultMap = new HashMap<String, Object>();boolean result = false;if (StringKit.isEmpty(url)) {resultMap.put("success", result);this.renderJson(resultMap);return;}String fileName = url.substring(url.lastIndexOf("/")+1);String upload_path = Constants.UPLOADS_PATH;String uploadpath = upload_path + File.separator + this.getSession().getAttribute("uid").toString()+ File.separator + fileName;final Map<String, String> headers = new HashMap<String, String>();headers.put("pragma", "no-cache");headers.put("cache-control", "no-cache");headers.put("Content-Type", "text/xml");result = HttpKit.downloadFile(url, headers, uploadpath);String downloadurl = Constants.LOCAL_SERVICE_URL+"uploads/"+this.getSession().getAttribute("uid").toString()+ File.separator + fileName;resultMap.put("url", downloadurl);resultMap.put("success", result);this.renderJson(resultMap);}
