Ajax跨域问题

ajax提交添加下面两行代码

contentType:‘application/json;charset=utf-8‘
data:JSON.stringify(数据)

var allData = {　　　　　　　　　　name:"张三",　　　　　　　　　　age:20　　　　　　　　　};$.ajax({
            type: "POST",
            url: "xxxx",
            contentType:‘application/json;charset=utf-8‘,
            data:JSON.stringify(allData),
            success: function (data) {
                alert(data);
            }
        });
