dataType: 'json' 和 contentType: 'application/json;charset=utf-8'
不然会报js跨域啊,Method 错误啊 等等一些乱七八糟的js错误.
下面直接上代码:

(二)Asp.Net WebApi+JQuery Ajax的Post请求整理
1.WebApi 默认支持Post提交处理,返回的结果为json对象,前台不需要手动反序列化处理。
2.WebApi 接收Post提交参数需要指定([FromBody] string name)
3.WebApi 中如果只接收一个基础类型参数,不能指定key的名称
4.WebApi Post请求Action只能接收一个参数,也就是说一个Action中[FromBody]仅可指定一次
5.WebApi Post请求处理多个参数可以使用类对象方式接收参数例如:Student
6.在接收Post参数时,如果不想定义类,可以使用Newtonsoft.Json.Linq的JObject json对象容器接收参数
7.(不推荐使用)此接收参数可以使用dynamic本质是使用的JObject,但是提交参数需要指定字符串类型,contentType: ‘application/json’,类似WebServer中的指定方式
8.在WebApi的Post请求处理中,后台的Action名称不能使用“GetXXX”方式命名
二、验证代码
1.单个参数传递
Post获取请求参数需要指定参数来源 [FromBody],
Post方式提交时,Action的名称不能使用’Get’名称开头,
如果只接收一个基础类型参数,不能指定key的名称
/// Post获取请求参数需要指定参数来源 [FromBody]
public string ShowName([FromBody] string name)
return $“您传入的名字:‘{name}’”;
public Dictionary<string, string> FindList([FromBody] bool IsShow)
Dictionary<string, string> dict = new Dictionary<string, string>();
if (IsShow)
dict.Add(“name1”, “张三”);
dict.Add(“name2”, “李四”);
return dict;
JavaScript:
$.post(’/api/postuser/showname’, {
‘’: ‘张三丰’
}, function (data) {
console.info(data);
alert(data);
$.post(’/api/postuser/FindList’, {
‘’: true
}, function (data) {
console.info(data);
alert(data);
二、多个参数传递
1.指定类类型 Student
public class Student
public string Name { get; set; }
public int Age { get; set; }
/// Post获取参数可以接收对象类型,接收多个参数
public string ShowName2([FromBody] Student stu)
return $"’{stu.Name}'的年龄为:{stu.Age}";
javascript:
$.post(’/api/postuser/showname2’, {
name: ‘张三丰’,
age: 19
}, function (data) {
console.info(data);
alert(data);
2.使用JObject
/// 在接收Post参数时,如果不想定义类,可以使用Newtonsoft.Json.Linq的JObject json对象容器接收参数
public object ShowName3([FromBody] JObject obj)
return new { name = obj[“name”], age = obj[“age”], success = true };
javascript:
//如果使用JObject,使用对象提交或者使用字符串提交后台都能获取成功
$.post(’/api/postuser/showname3’, {
name: ‘张三丰’,
age: 19
}, function (data) {
console.info(data);
alert(data);
3.使用dynamic(不推荐)
/// 在接收Post参数时,如果前台传入参数为一个字符串,可以使用dynamic类型接收,不需要指定[FromBody]
/// 此处obj的真正类型:FullName = “Newtonsoft.Json.Linq.JObject”
public object ShowName3(dynamic obj)
return new { name = obj[“name”], age = obj[“age”], success = true };
javascript:
//需要指定参数类型:contentType: ‘application/json’,类似WebServer中的指定方式
$.ajax({
url: ‘/api/postuser/showname3’,
type:‘post’,
contentType: ‘application/json’,
data: JSON.stringify({ name: ‘张三丰’, age: 19 }),
success: function (data) {
console.info(data);
alert(data);
Asp.Net WebApi+AngularJs $http的Post请求整理
1.后台使用如上相同
2.$http服务的post在单个参数提交后台接收失败
3.$http的post提交后台要么使用类类型接收,要么使用JObject接收(包含单个或多个参数)
二、代码示例
1.单个参数
//单个参数提交,后台接收失败
$http.post(’/api/postuser/showname’, {
‘’: ‘张三’
}).then(function (result) {
console.info(result);
alert(result.data);
}).catch(function (err) {
console.info(err);
alert(err.data.Message);
//单个参数提交,后台使用JObject接收成功
$http.post(’/api/postuser/showlist’, {
isshow: false
}).then(function (result) {
console.info(result);
alert(result.data);
}).catch(function (err) {
console.info(err);
alert(err.data.Message);
2.多个参数
//多个参数提交,Student类型接收参数
$http.post(’/api/postuser/showname2’, {
name: ‘张三’,
age: ‘15’
}).then(function (result) { //正确请求成功时处理
console.info(result);
alert(result.data);
}).catch(function (result) { //捕捉错误处理
console.info(result);
alert(result.data.Message);
//多个参数提交,JObject接收参数
//WebApi,相应结果为json对象,不需要手动发序列化处理
$http.post(’/api/postuser/showname3’, {
name: ‘张三’,
age: ‘15’
}).then(function (result) { //正确请求成功时处理
console.info(result);
alert(result.data.name);
}).catch(function (result) { //捕捉错误处理
console.info(result);
alert(result.data.Message);
