jQuery File Upload跨域上传

时间:2021-10-11 08:01:23

  最近在做一个一手粮互联网项目,方案为前后端分离,自己负责前端框架,采用了Requirejs+avalonjs+jquery三个框架完成。

  前后端通过跨域实现接口调用,中间也发现了不少问题,尤其是在富文本编辑器和上传插件跨域的处理过程中,费劲了脑汁,总算解决了。

  上传选择了jQuery File Upload,兼容性还是相对不错,并且支持跨域,但是没有一个完整的跨域Demo,只能看源码找帮助。

  页面实现方法:

  页面引入:

  <link rel="stylesheet" type="text/css" href="../../src/widget/jQueryFileUpload/css/jquery.fileupload.css">
  <link rel="stylesheet" type="text/css" href="../../src/widget/jQueryFileUpload/css/jquery.fileupload-ui.css">
  <script type="text/javascript" src=".../../src/widget/jQueryFileUpload/js/vendor/jquery.ui.widget.js"></script>
  <script type="text/javascript" src=".../../src/widget/jQueryFileUpload/js/jquery.iframe-transport.js"></script>
  <script type="text/javascript" src=".../../src/widget/jQueryFileUpload/js/jquery.fileupload.js"></script>   上传页面
  <input id="fileupload" type="file" name="files" multiple>
 $('#fileupload').fileupload({
url: config.getUrl()+"upload!upload.do",
type:"POST",
dataType:"json",
autoUpload : true,
acceptFileTypes: /(\.|\/)(jpe?g|png)$/i,
formData: {model:1},
forceIframeTransport: true,
redirectParamName:"callUrl",
redirect:"http://"+window.location.host+"/app/callupload.html?",//回调页面
done: function (e, data) {
$.each(data.result.files, function (index, file) {
model.fileVO.push({attach_root_id:file.id,file_path:file.url});
});
},
fail:function(e,data){
console.log("上传失败:"+data.errorThrown);
}
});

  创建一个回调页面callupload.html

<body>
<script type="text/javascript">
document.body.innerText=document.body.textContent=decodeURIComponent(window.location.search.slice(1));
</script>
</body>

  上传后台:

 string result = file.FileName;
context.Response.Headers.Add("Cache-Control", "no-cache");
context.Response.AddHeader("Access-Control-Allow-Origin", "*");
context.Response.AddHeader("Access-Control-Allow-Headers", "x-requested-with");
context.Response.AddHeader("Location", callUrl + "?msg=" + result);
context.Response.Redirect(callUrl + "?msg=" + result);
