ExtJS Ajax（JSON）帖子无法正常工作

Question

我在stackoverflow本身以及extjs文档中看到过几个例子。但我只能看到404错误。

       Ext.Ajax.request({
            url: '/project-desktop-service/decisions.json',
            method: 'post',        
            headers: {'Content-Type': 'application/json'},
            params: {
                rolename: 'rolename'
            },
            success: function(){console.log('success');},
            failure: function(){console.log('failure');}
        });

我也尝试过删除和添加内容类型的不同组合，添加绝对URL等。但每次结果都是同样的失败。

来自Wiki：

  The 404 or Not Found error message is a HTTP standard response code indicating that 
  the client was able to communicate with the server, 
  but the server could not find what was requested.

唯一没有功能的是你的URL或你要求的东西不是。
