WebApi 接口参数传参详解

下面通过几个示例看看我们的get请求参数传递。

get请求的数据会附在URL之后（就是把数据放置在HTTP协议头中），而post请求则是放在http协议包的包体中。

1.基础类型参数

[HttpPost]public bool SaveData([FromBody]string NAME){     return true;}
$.Ajax({        type: "post",        url: "http://localhost:27221/api/Charging/SaveData",        data: { "": "Jim" },        success: function (data, status) {}    });2.实体类型参数public class TB_CHARGING    {        /// <summary>        /// 主键Id        /// </summary>        public string ID { get; set; }        /// <summary>        /// 充电设备名称        /// </summary>        public string NAME { get; set; }        /// <summary>        /// 充电设备描述        /// </summary>        public string DES { get; set; }        /// <summary>        /// 创建时间        /// </summary>        public DateTime CREATETIME { get; set; }    }[HttpPost]        public bool SaveData(TB_CHARGING oData)        {            return true;        }$.ajax({        type: "post",        url: "http://localhost:27221/api/Charging/SaveData",        contentType: 'application/json',        data: JSON.stringify({ NAME: "Jim",DES:"备注" }),        success: function (data, status) {}    });3.实体集合var arr = [        { ID: "1", NAME: "Jim", CREATETIME: "1988-09-11" },        { ID: "2", NAME: "Lilei", CREATETIME: "1990-12-11" },        { ID: "3", NAME: "Lucy", CREATETIME: "1986-01-10" }    ];    $.ajax({        type: "post",        url: "http://localhost:27221/api/Charging/SaveData",        contentType: 'application/json',        data: JSON.stringify(arr),        success: function (data, status) {}    });[HttpPost]        public bool SaveData(List<TB_CHARGING> lstCharging)        {            return true;        }4.后台发送请求参数的传递public void TestReques()　　　　{    　　　　 //请求路径            string url = "http://localhost:27221/api/Charging/SaveData";            //定义request并设置request的路径            WebRequest request = WebRequest.Create(url);            request.Method = "post";            //初始化request参数            string postData = "{ ID: /"1/", NAME: /"Jim/", CREATETIME: /"1988-09-11/" }";            //设置参数的编码格式，解决中文乱码            byte[] byteArray = Encoding.UTF8.GetBytes(postData);            //设置request的MIME类型及内容长度            request.ContentType = "application/json";            request.ContentLength = byteArray.Length;            //打开request字符流            Stream dataStream = request.GetRequestStream();            dataStream.Write(byteArray, 0, byteArray.Length);            dataStream.Close();            //定义response为前面的request响应            WebResponse response = request.GetResponse();            //获取相应的状态代码            Console.WriteLine(((HttpWebResponse)response).StatusDescription);            //定义response字符流            dataStream = response.GetResponseStream();            StreamReader reader = new StreamReader(dataStream);            string responseFromServer = reader.ReadToEnd();//读取所有            Console.WriteLine(responseFromServer);　　　　}
