您可以将ModelBinding与GET请求一起使用吗?

我刚刚测试了这个,它确实可以工作(至少在.NETCore3.1中是这样)

[HttpGet("test")]
        public IActionResult TestException([FromQuery]Test test)
        {
            return Ok();
        }

        public class Test
        {
            public int Id { get; set; }
            public string Yes { get; set; }
        }

例如

 public class UserFilterAttribute : ActionFilterAttribute
{
        public override void OnActionExecuting(HttpActionContext actionContext)
        {
            var controller = actionContext.ControllerContext.Controller as CustomApiController;
            var queryParams = actionContext.Request.GetQueryNameValuePairs();
            var ageParam = queryParams.SingleOrDefault(a => a.Key == "age");
            var statusParam = queryParams.SingleOrDefault(a => a.Key == "status");

            controller.UserFilter = new UserFilter { 
                                          Age = int.Parse(ageParam.Value),
                                          Status = statusParam.Value
                                          };
        }
}

CustomApiController(从当前控制器继承)具有UserFilter属性,因此可以将值保留在那里。如果某些查询参数未随请求一起发送,也可以添加空检查。。

最后,您可以装饰您的控制器方法

[HttpGet]
[UserFilter]
public async Task<JsonResult> Get() 
{
    var age = UserFilter.age;
    var status = UserFilter.status;
}
