我是用的例子里的示例代码，不应该有不安全字符啊。

$.ajax({

url: 'myorders',

"data": JSON.stringify(params), // 注意要转为json,除非data本身就是json字符串

dataType: 'json',

success: function (params) {

console.log(params);

}

});

生成的URL是这个

?{%22type%22:%221%22,%22status%22:%222%22,%22timeperiods%22:{%22startDate%22:%22%22,%22endDate%22:%22%22}}

对应的@At应该怎么写？
