美图秀秀头像编辑器的使用？ thinkphp+七牛方案

我用thinkphp，上传到七牛。下面是官方的一个html和一个接口
搞了半天，一天头绪都没有，请指教一下大概的方案

这里是html

/第1个参数是加载编辑器div容器，第2个参数是编辑器类型，第3个参数是div容器宽，第4个参数是div容器高/
xiuxiu.embedSWF("altContent",5,"100%","100%");
//修改为您自己的图片上传接口
xiuxiu.setUploadURL("APP/Home/Home/Staff/uploadHead");
xiuxiu.setUploadType(2);
xiuxiu.setUploadDataFieldName("upload_file");
xiuxiu.onInit = function ()
{
xiuxiu.loadPhoto("http://open.web.meitu.com/sources/images/1.jpg");
}
xiuxiu.onUploadResponse = function (data)
{
alert("上传响应" + data);
}
}

这里是官方的处理接口
