 public class peopleController : ApiController
 {
     [HttpGet]
     public IHttpActionResult getAllPeople(string Name, string Age)
     {
        //Return something
     }
 }

我的WebApiConfig是这样的:

config.Routes.MapHttpRoute(
            name: "getAllPeopleApi",
            routeTemplate: "people",
            defaults: new { controller = "people", action = "getAllPeople" }

        );

http://localhost:xxx/people?Name=&Age= . 它工作得很好。

http://localhost:xxx/people http://localhost:xxx/people?Name= , http://localhost:xxx/people?Age=

我收到了这个错误信息:

{"Message":"No HTTP resource was found that matches the request URI 'http://localhost:xxxx/......'.","MessageDetail":"No action was found on the controller 'people' that matches the request."}

routeTemplate: "people/{Name}/{Age}" Error 404.0 Not Found

routeTemplate: "people/{Name}/{Age}"

这部分不是查询字符串,而是动态路径。这意味着你的道路 Domain/people/SomeName/SomeAge?QueryString=Whatever

通过显式设置参数解决了这个问题 Name Age Null .

public class peopleController : ApiController
 {
     [HttpGet]
     public IHttpActionResult getAllPeople(string Name = null, string Age=null)
     {
        //Return something
     }
 }

这将使参数成为可选参数。现在可以使用或不使用查询字符串参数调用控制器。
