  您需要为请求的“Content-Type” Headers 使用“使用”注释元素，并为您的请求的“Accept” Headers “生成”注释元素：

  @RequestMapping(value = "/home",
                 method = RequestMethod.POST,
               consumes = {"application/json", "application/x-www-form-urlencoded"},
               produces = "application/json")
  

  ref：Annotation Type RequestMapping

  这些RequestMapping元素可用于Spring 4.如果使用Spring 2，则需要使用“params”元素，而不是“consume”和“produce”元素：

  @RequestMapping(value = "/home",
                 method = RequestMethod.POST,
                 params = {"content-type=application/json",
                           "content-type=application/x-www-form-urlencoded",
                           "Accept=application/json"})

  获取refrash令牌

              if (authorizationState != null)

                  ViewBag.AccessToken = authorizationState.AccessToken;
                  ViewBag.RefreshToken = authorizationState.RefreshToken;
                  ViewBag.Action = Request.Path;
              }

              userAuthorization.Send(HttpContext);
              Response.End();
          }
          else if (!string.IsNullOrEmpty(Request.Form.Get("submit.Refresh")))
          {
              var state = new AuthorizationState
              {
                  AccessToken = Request.Form["AccessToken"],
                  RefreshToken = Request.Form["RefreshToken"]
              };
              if (_webServerClient.RefreshAuthorization(state))

              var client = new HttpClient(_webServerClient.CreateAuthorizingHandler(accessToken));
              var body = client.GetStringAsync(new Uri(resourceServerUri, Paths.MePath)).Result;
              ViewBag.ApiResponse = body;
          }
  
          return View();
      }
  
      private void InitializeWebServerClient()
      {
          var authorizationServerUri = new Uri(Paths.AuthorizationServerBaseAddress);
          var authorizationServer = new AuthorizationServerDescription
          {
              AuthorizationEndpoint = new Uri(authorizationServerUri, Paths.AuthorizePath),
              TokenEndpoint = new Uri(authorizationServerUri, Paths.TokenPath)
          };
          _webServerClient = new WebServerClient(authorizationServer, Clients.Client1.Id, Clients.Client1.Secret);
      }
  }

  您可以在xml中的@RequestMapping和ViewResolver中定义consumemes属性 . 下面：

  • @RequestMapping（consumemes = []）

  • ContentNegotiatingViewResolver
