使用uploadify插件，上传的文件成功了，却还报404错误
前端代码：
<div class="upload-pic img-wrap">
<input type="hidden" name="info[pic]" id="pic" value="">
<a href="javascript:void(0);" onclick="attachupload('single_image_images', '附件上传','single_image',thumb_images,'1,gif|jpg|jpeg|png|bmp,1,,,0','image','/Admin/Upfile/upload');return false;">
<img src="__PUBLIC__/images/admin/icon/upload-pic.png" id="single_image_preview" width="135" height="113" style="cursor:hand">
</a>
<input type="button" style="width: 66px;" class="button" onclick="attachupload('single_image_images', '附件上传','single_image',thumb_images,'1,gif|jpg|jpeg|png|bmp,1,,,0','image','/Admin/Upfile/upload');return false;" value="上传图片">
<input type="button" style="width: 66px;" class="button" onclick="$('#single_image_preview').attr('src','__PUBLIC__/images/admin/icon/upload-pic.png');$('#single_image').val(' ');return false;" value="取消图片">
</div>
点击上传图片后在iframe中打开如下页面
<body>

404错误，提示文件未找到，查看文件路径
我仅有的5个币都贡献了，求大神解答~~
/youcku/index.php/Admin/Upfile/upload你这个页面是不是做了302跳转到其他页面了？是跳转的页面出错了
不要跳转，输出success或者error这种内容提供给uploadify接收就行
