MVC 6多種獲取方法

Question

我試圖支持每個控制器的多個Get（）方法，以及通過web api可訪問的特定命名方法。我已經在MVC 5中做了這個，但似乎無法弄清楚它是如何在MVC 6中完成的。任何想法？謝謝。

您可以使用屬性路由鏈路上，這 -

[Route("api/[controller]")] /* this is the defualt prefix for all routes, see line 20 for overridding it */ 
public class ValuesController : Controller 
{ 
    [HttpGet] // this api/Values 
    public string Get() 
    { 
     return string.Format("Get: simple get"); 
    } 

    [Route("GetByAdminId")] /* this route becomes api/[controller]/GetByAdminId */ 
    public string GetByAdminId([FromQuery] int adminId) 
    { 
     return $"GetByAdminId: You passed in {adminId}"; 
    } 

    [Route("/someotherapi/[controller]/GetByMemberId")] /* note the/at the start, you need this to override the route at the controller level */ 
    public string GetByMemberId([FromQuery] int memberId) 
    { 
     return $"GetByMemberId: You passed in {memberId}"; 
    } 

    [HttpGet] 
    [Route("IsFirstNumberBigger")] /* this route becomes api/[controller]/IsFirstNumberBigger */ 
    public string IsFirstNumberBigger([FromQuery] int firstNum, int secondNum) 
    { 
     if (firstNum > secondNum) 
     { 
      return $"{firstNum} is bigger than {secondNum}"; 
     } 
     return $"{firstNum} is NOT bigger than {secondNum}"; 
    } 
}

不能有多個具有相同url模式的Get方法。您可以使用屬性路由併爲不同的url模式設置多個GET方法。

[Route("api/[controller]")] 
public class IssuesController : Controller 
{ 
    // GET: api/Issues 
    [HttpGet] 
    public IEnumerable<string> Get() 
    { 
     return new string[] { "item 1", "item 2" }; 
    } 

    // GET api/Issues/5 
    [HttpGet("{id}")] 
    public string Get(int id) 
    { 
     return "request for "+ id; 
    } 

    // GET api/Issues/special/5 
    [HttpGet("special/{id}")] 
    public string GetSpecial(int id) 
    { 
     return "special request for "+id; 
    } 
    // GET another/5 
    [HttpGet("~/another/{id}")] 
    public string AnotherOne(int id) 
    { 
     return "request for AnotherOne method with id:" + id; 
    } 
    // GET api/special2/5 
    [HttpGet()] 
    [Route("~/api/special2/{id}")] 
    public string GetSpecial2(int id) 
    { 
     return "request for GetSpecial2 method with id:" + id; 
    } 
} 

你可以看到，我用兩個HttpGet和Route屬性來定義的路由模式。

通過上述配置，你會得到以下答覆

請求URL：yourSite/API /問題/

結果["value1","value2"]

請求的URL：yourSite/api/issues/4

結果request for 4

請求URL：yourSite/API/SPECIAL2/6

結果request for GetSpecial2 method with id:6

請求URL：yourSite /另一/ 3

結果request for AnotherOne method with id:3
