自定义错误消息
public class ErrorMessage:DelegatingHandler { protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) { return base.SendAsync(request, cancellationToken).ContinueWith<HttpResponseMessage>((responseToCompleteTask) => { HttpResponseMessage response = responseToCompleteTask.Result; HttpError error = null; if (response.TryGetContentValue<HttpError>(out error)) { //自定义错误处理 //error.Message = "这个接口调用出错了"; } if (error != null) { //这是本人创建的一个返回类 var resultMsg = new BaseResModel<BaseModel> { errorno = (int)response.StatusCode, page = -1, total = -1, records = -1 }; return new HttpResponseMessage { Content = new StringContent(SerializeUtils<BaseResModel<BaseModel>>.Serialize(resultMsg), System.Text.Encoding.GetEncoding("UTF-8"), "application/json"), StatusCode = HttpStatusCode.OK }; } else { return response; } }); } }
全局异常处理包括404
public class NotFoundActionSelector: ApiControllerActionSelector { public override HttpActionDescriptor SelectAction(HttpControllerContext controllerContext) { HttpActionDescriptor decriptor = null; try { decriptor = base.SelectAction(controllerContext); } catch (HttpResponseException ex) { var code = ex.Response.StatusCode; if (code != HttpStatusCode.NotFound && code != HttpStatusCode.MethodNotAllowed) throw; var routeData = controllerContext.RouteData; routeData.Values["action"] = "Handle404"; IHttpController httpController = new ErrorController(); controllerContext.Controller = httpController; controllerContext.ControllerDescriptor = new HttpControllerDescriptor(controllerContext.Configuration, "Error", httpController.GetType()); decriptor = base.SelectAction(controllerContext); } return decriptor; } }
public class NotFoundControllerSelector : DefaultHttpControllerSelector { public NotFoundControllerSelector(HttpConfiguration configuration) : base(configuration) { } public override HttpControllerDescriptor SelectController(HttpRequestMessage request) { HttpControllerDescriptor decriptor = null; try { decriptor = base.SelectController(request); } catch (HttpResponseException ex) { var code = ex.Response.StatusCode; if (code != HttpStatusCode.NotFound) throw; var routeValues = request.GetRouteData().Values; routeValues["controller"] = "Error"; routeValues["action"] = "Handle404"; decriptor = base.SelectController(request); } return decriptor; } }
权限过滤
public class SupportFilter : AuthorizeAttribute { //重写基类的验证方式，加入我们自定义的Ticket验证 RedisHelper redis = new RedisHelper(1); public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext actionContext) { //url获取token var content = actionContext.Request.Properties["MS_HttpContext"] as HttpContextBase; var token = content.Request.QueryString["Token"]; var userid = content.Request.QueryString["userid"] != null ? int.Parse(content.Request.QueryString["userid"]) : 0; var mac = content.Request.QueryString["mac"] != null ? content.Request.QueryString["mac"] : null; var routes = new RouteCollection(); RouteConfig.RegisterRoutes(routes); RouteData routeData = routes.GetRouteData(content); //取出区域的控制器Action,id string controller = actionContext.ActionDescriptor.ControllerDescriptor.ControllerName; string action = actionContext.ActionDescriptor.ActionName; //URL路径 string filePath = HttpContext.Current.Request.FilePath; if ((controller.ToLower() == "user" && action.ToLower() == "login") || (controller.ToLower() == "user" && action.ToLower() == "register" )|| (controller.ToLower() == "banner" && action.ToLower() == "getbanner") || (controller.ToLower() == "device" && action.ToLower() == "login")) { } else { var attributes = actionContext.ActionDescriptor.GetCustomAttributes<AllowAnonymousAttribute>().OfType<AllowAnonymousAttribute>(); bool isAnonymous = attributes.Any(a => a is AllowAnonymousAttribute); if (isAnonymous) base.OnAuthorization(actionContext); if (userid != 0 && token != null && token.Length > 0) { if (redis.StringGet("user_token_" + userid.ToString()) != token) { HandleUnauthorizedRequest(actionContext); } } else if (mac != null && token != null && token.Length > 0) { if (redis.StringGet("device_token_" + mac) != token) { HandleUnauthorizedRequest(actionContext); } } else HandleUnauthorizedRequest(actionContext); } } protected override void HandleUnauthorizedRequest(HttpActionContext actionContext) { base.HandleUnauthorizedRequest(actionContext); if (actionContext.Response.StatusCode == System.Net.HttpStatusCode.Unauthorized) { actionContext.Response.Content = new StringContent(SerializeUtils<BaseResModel<BaseModel>>.Serialize(new BaseModel() { errorno = -4, errormsg = "" }), System.Text.Encoding.UTF8, "application/json"); } } }
