发送对象

Question

我试图通过HTTP的方法来访问下面的WebAPI控制器的方法

[System.Web.Http.Route("api/Users/Signin")] 
    [ResponseType(typeof(bool))] 
    public bool UserSingIn(User obj) 
    { 
     bool isuserexit = _usersRepo.UserSignIn(obj); 
     if (isuserexit == true) 
     { 
      return true; 
     } 

     return false; 
    } 

这是HTTP方法我试图用送User obj对象，

private string USER_URL = "http://localhost:3623/api/Users"; 

    public bool GetUser(User obj) 
    { 
     try 
     { 
      HttpClient client = new HttpClient(); 
      client.BaseAddress = new Uri(USER_URL); 
      client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 
      HttpResponseMessage response = client.PutAsJsonAsync("Users/Signin", obj).Result; 
      if (response.IsSuccessStatusCode) 
       return response.Content.ReadAsAsync<bool>().Result; 
      return false; 

     } 
     catch 
     { 
      return false; 
     } 

    } 

但是这以response : {StatusCode: 405, ReasonPhrase: 'Method Not Allowed', ..}

Answer 1

结束您的Web API默认只处理GET请求。如果你想使用它，你需要用HttpPut属性来修饰它。

[HttpPut] 
[System.Web.Http.Route("api/Users/Signin")] 
[ResponseType(typeof(bool))] 
public bool UserSingIn(User obj)

您可以使用postAsync方法。

var data = JsonConvert.SerializeObject(dataToSave); 
var content = new StringContent(data, Encoding.UTF8, "application/json"); 
var resp = client.PostAsync(apiUrl, content).Result;
