1、json参数为json字符串
var data = {
name: '超管不是11',
password: '123456'
};
$.ajax({
type:"post",
url: url,
data: JSON.stringify(data),//这里格式为JSON字符串
dataType: 'json',//返回数据类型
contentType:"application/json;charset=utf-8",//这里注明传递参数类型为JSON字符串
success: function (rs) {
console.log(rs);
}
});
@RequestMapping(value = "/login")
//后台需要加上@RequestBody
public Result login(@RequestBody User user){
System.out.println(user);
return ResultUtil.success(ResultEnum.SUCCESS, null);
}
2、JSON参数为JSON对象
var data = {
name: '超管不是11',
password: '123456'
};
$.ajax({
type:"post",
url: url,
data: {
name: '超管不是11',//或者 "name": "xxx"
password: '123456'// "password": "xxx"
},//这里格式为JSON对象
dataType: 'json',//返回数据类型
//contentType:"application/json;charset=utf-8",//这里需要注释掉
success: function (rs) {
console.log(rs);
}
});
@RequestMapping(value = "/login")
//public Result login(@RequestBody User user){
// System.out.println(user);
// return ResultUtil.success(ResultEnum.SUCCESS, null);
//}
//后台需要去掉@RequestBody, 必须去掉
public Result login(User user){
System.out.println(user);
return ResultUtil.success(ResultEnum.SUCCESS, null);
}
