[英]Web API routing not working properly (action names)
I got the following code, and I can't get the action name to work or is something else wrong here? 我得到了以下代码,但我无法获得动作名称,或者这里还有其他问题吗? I want to create a custom search, where usually when you look for one object in an api you search for the id, but I would like to search for the weekday for instance, but it could really be anything.
我想创建一个自定义搜索,通常当您在api中查找一个对象时,便会搜索ID,但是例如,我想搜索工作日,但实际上可以是任何东西。
DayController.cs : DayController.cs:
[ActionName("Weekday")]
public IHttpActionResult GetDayWeek(string q_day) {
var day = controller.GetDay(q_day);
if (day == null) {
return NotFound();
}
return Ok(day);
}
Controller.cs : Controller.cs:
public Day GetDay(string q_day) {
var day = dal.GetDayByWeekday(q_day);
return day;
}
Dal.cs : Dal.cs:
public Day GetDayByWeekday(string q_day) {
var day = db.Day.Where(d = > d.Weekday == q_day).Single();
return day;
}
WebApiConfig.cs : WebApiConfig.cs:
public static void Register(HttpConfiguration config) {
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new {
id = RouteParameter.Optional
});
}
Error: 错误:
<Error>
<Message>
No HTTP resource was found that matches the request URI 'http://localhost:2096/api/Day/Weekday/monday'.
</Message>
<MessageDetail>
No action was found on the controller 'Day' that matches the request.
</MessageDetail>
</Error>
Changing this: 改变这个:
[ActionName("Weekday")]
public IHttpActionResult GetDayWeek(string q_day) {
var day = controller.GetDay(q_day);
if (day == null) {
return NotFound();
}
return Ok(day);
}
To this: 对此:
[Route("api/day/weekday/{q_day}")]
public IHttpActionResult GetDayWeek(string q_day) {
var day = controller.GetDay(q_day);
if (day == null) {
return NotFound();
}
return Ok(day);
}
Did the trick in my testing 在我的测试中成功了
Some credit goes to JLevett for making me look at the Route-attribute 感谢JLevett让我看看Route-attribute
To explain: 解释:
The Route-attribute overrides the path to the method you're trying to call. 路由属性会覆盖您尝试调用的方法的路径。 Therefore it needs to be a full path with parameter names in it.
因此,它必须是其中包含参数名称的完整路径。
Do you have a method with multiple parameters this should work: 您是否有一个具有多个参数的方法,它应该可以工作:
[Route("api/day/weekday/{q_day}/{w_day}")]
public IHttpActionResult GetDayWeekAndMore(string q_day, string w_day) {
