实施搜索不能在网络API中工作

Question

在我们的移动应用程序的网页API上工作，我们似乎无法让我们的搜索方法工作。 当我们试图从我们得到以下结果对我们的搜索方法

<Error> 
<Message> 
No HTTP resource was found that matches the request URI 'https://hippokros-  api.azurewebsites.net/api/Recommends/GetCardRecommendsByFriendId/100000097477513'. 
</Message> 
<MessageDetail> 
No action was found on the controller 'Recommends' that matches the request. 
</MessageDetail> 
</Error> 

API调用我们提琴手得到一个502的HTTP请求，但是当我们调用GetRecommends/1，并通过在id我们得到的成绩。

是控制器代码很短，所以我将只显示它的所有

public class RecommendsController : ApiController 
{ 
    private mtgServiceEntities db = new mtgServiceEntities(); 

    // GET: api/Recommends 
    [HttpGet] 
    public IQueryable<Recommend> GetRecommends() 
    { 
     return db.Recommends; 
    } 

    // GET: api/Recommends/5 
    [ResponseType(typeof(Recommend))] 
    [HttpGet] 
    public IHttpActionResult GetRecommend(int id) 
    { 
     Recommend recommend = db.Recommends.Find(id); 

     if (recommend == null) 
     { 
      return NotFound(); 
     } 

     return Ok(recommend); 
    } 

    // GET: api/Recommends/5 
    [ResponseType(typeof(Recommend))] 
    [HttpGet] 
    public IHttpActionResult GetRecommend(string cardname) 
    { 
     List<Recommend> recommend = db.Recommends.Where(x => x.card_name == cardname).ToList(); 

     if (recommend == null) 
     { 
      return NotFound(); 
     } 

     return Ok(recommend); 
    } 

    //GET: api/Recommend/Search/cardname 
    [ResponseType(typeof(Recommend))] 
    [HttpGet] 
    public IHttpActionResult GetFriendRecommendsByCardName(string cardname) 
    { 
     List<Recommend> recommends = db.Recommends.Where(x => x.card_name == cardname).ToList(); 
     return Ok(recommends); 
    } 

    [ResponseType(typeof(Recommend))] 
    [HttpGet] 
    public IHttpActionResult GetCardRecommendsByFriendId(string friendId) 
    { 
     List<Recommend> recommends = db.Recommends.Where(x => x.facebookId == friendId).ToList(); 
     return Ok(recommends); 
    } 

    // PUT: api/Recommends/5 
    [ResponseType(typeof(void))] 
    public IHttpActionResult PutRecommend(int id, Recommend recommend) 
    { 
     if (!ModelState.IsValid) 
     { 
      return BadRequest(ModelState); 
     } 

     if (id != recommend.ID) 
     { 
      return BadRequest(); 
     } 

     db.Entry(recommend).State = EntityState.Modified; 

     try 
     { 
      db.SaveChanges(); 
     } 
     catch (DbUpdateConcurrencyException) 
     { 
      if (!RecommendExists(id)) 
      { 
       return NotFound(); 
      } 
      else 
      { 
       throw; 
      } 
     } 

     return StatusCode(HttpStatusCode.NoContent); 
    } 

    // POST: api/Recommends 
    [ResponseType(typeof(Recommend))] 
    public IHttpActionResult PostRecommend(Recommend recommend) 
    { 
     if (!ModelState.IsValid) 
     { 
      return BadRequest(ModelState); 
     } 

     db.Recommends.Add(recommend); 

     try 
     { 
      db.SaveChanges(); 
     } 
     catch (DbUpdateException) 
     { 
      if (RecommendExists(recommend.ID)) 
      { 
       return Conflict(); 
      } 
      else 
      { 
       throw; 
      } 
     } 

     return CreatedAtRoute("DefaultApi", new { id = recommend.ID }, recommend); 
    } 

    // DELETE: api/Recommends/5 
    [ResponseType(typeof(Recommend))] 
    public IHttpActionResult DeleteRecommend(int id) 
    { 
     Recommend recommend = db.Recommends.Find(id); 
     if (recommend == null) 
     { 
      return NotFound(); 
     } 

     db.Recommends.Remove(recommend); 
     db.SaveChanges(); 

     return Ok(recommend); 
    } 

    protected override void Dispose(bool disposing) 
    { 
     if (disposing) 
     { 
      db.Dispose(); 
     } 
     base.Dispose(disposing); 
    } 

    private bool RecommendExists(int id) 
    { 
     return db.Recommends.Count(e => e.ID == id) > 0; 
    } 
} 

和我们在webapiconfig文件路由如下

public static void Register(HttpConfiguration config) 
    { 
     //Web API configuration and services 
     config.EnableCors(); 

     // Web API configuration and services 
     // Configure Web API to use only bearer token authentication. 
     config.SuppressDefaultHostAuthentication(); 
     config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType)); 

     // Web API routes 
     config.MapHttpAttributeRoutes(); 

     config.Routes.MapHttpRoute(
      name: "DefaultApi", 
      routeTemplate: "api/{controller}/{action}/{id}", 
      defaults: new { id = RouteParameter.Optional } 
     ); 
    } 

我们不知道设置或配置我们有错，但基本上它告诉我们，当我们知道我们有正确的URL并且我们使用https来调用它时，没有什么。

请帮忙！

我使用属性路由，因为我可以很容易地看到什么映射到什么:)我推荐阅读this article以更好地理解Web API属性路由。

要匹配你的地址，你可以试试下面的代码：

[RoutePrefix("api/recommends")] 
public class RecommendsController : ApiController 
{ 
    ... 

    Route("GetCardRecommendsByFriendId/{friendId}")] 
    [ResponseType(typeof(Recommend))] 
    [HttpGet] 
    public IHttpActionResult GetCardRecommendsByFriendId(string friendId) 
    { 
     List<Recommend> recommends = db.Recommends.Where(x => x.facebookId == friendId).ToList(); 
     return Ok(recommends); 
    }   
}
