/*

*/
$.post(apiUrl.getOne("PostFourth"),
    { name: ‘张三‘, age: 12 },
    function (data) {
        alert(data);
    });
$.ajax({
    url: apiUrl.getOne("PostFourth"),

    type: ‘post‘,
    success: function (data) {
        console.info(data);
        alert(data);

});

//Post请求 1个或多个对象参数
public string PostFourth([FromBody]Newtonsoft.Json.Linq.JObject data)
{
    //return data.ToString();
    dynamic result = data;
    return result.name;
