问题 JSON Serialization (ASP.Net Web API) fails because of self-referencing loop (it’s a common problem, Reason: an entity being requested lazy loads child entities and every child has a back reference to parent entity). Work around I found, but doesn’t help me: Use [JsonIgnore] for navigation properties to be ignored: This solution works but doesn’t apply in my case. For Example: To get a Customer information along with his Orders, I would quickly add [JsonIgnore] to Customer property in Order

问题 I have read many articles in the web so far, about the differences between WCF and ASP.Net web API. Unfortunately I could not come up to a clear idea about what will serve my purpose. Most of the Articles I have read highlighted on the design point of view of the two web services. But I am confused what will work best for my project and why? Here is my brief description of the project. I need to create a communication channel between two servers (both are written in C#). The servers will

问题 I use PushStreamContent with my REST API (ASP.NET Web API) and works great. The HttpClient can request a ressource and gets the HTTP-Response before the complete request is handled by the server (the server still writes to the push-stream). As HttpClient you have to do one little thing: Use HttpCompletionOption.ResponseHeadersRead. Now my question: Is it possible to to this the other way? From the HttpClient -> uploading data via a push-stream to the web api? I Implemented it as below, but

问题 I have .NET core Web API which as service layer. Service layer has all EF code. If have basecontroller with this code protected Task<IActionResult> NewTask(Func<IActionResult> callback) { return Task.Factory.StartNew(() => { try { return callback(); } catch (Exception ex) { Logger.LogError(ex.ToString()); throw; } }); } In controller action I wrap all calls to service in above method e.g. : [HttpGet("something")] public async Task<IActionResult> GetSomething(int somethingId) { return await

问题 Is it possible to add custom validation to each request when authenticating web api calls using a bearer token? I'm using the following configuration and the application already validates the JWT tokens correctly. app.UseOAuthAuthorizationServer(new OAuthAuthorizationServerOptions { AuthenticationType = "jwt", TokenEndpointPath = new PathString("/api/token"), AccessTokenFormat = new CustomJwtFormat(), Provider = new CustomOAuthProvider(), }); app.UseJwtBearerAuthentication(new

问题 I'm new to ASP.NET webapi and I can't find a way to return a list of objects queried by id. This is my controller method for the GET request. I want to return all the questions which have a specified questionnaireId passed via url. I tried this: // GET: api/Questions/5 [ResponseType(typeof(List<Question>))] public Task<IHttpActionResult> GetQuestion(int questionnaireId) { var questions = from q in db.Questions where q.QuestionnaireId == questionnaireId select new Question() { Id = q.Id,

问题 Compared to AppDomain.GetAssemblies() , BuildManager.GetReferencedAssemblies() (System.Web.Compilation.BuildManager) seems a more reliable way to get the assemblies that are referenced by an ASP.NET application at runtime, since AppDomain.GetAssemblies() only gets "the assemblies that have already been loaded into the execution context of this application domain". Iterating through all assemblies is an important tool for dynamically registering types at application start-up in your DI

问题 Assume i have this model public partial class Todo { public int id { get; set; } public string content { get; set; } public bool done { get; set; } } And i send this as json data to my controller as a patch request. This is mearly the action of toggeling a checkbox. I think it makes sence that i only want to sent that to my server, and not the entire model. { "id":1, "done" : true } What does my WebApi controller need to look like in order to correctly process this, simple, json patch request

问题 Given a controller Proxy and an action of GetInformation . I want to be able to call the method GetInformation of the Users controller. Both the WebAPI controllers are in the same project but direct calls like var controller = new UsersController(); return controller.GetInformation(request); Doesn't work. The signature is: public HttpResponseMessage GetInformation(InformationRequest request) I do not want to do a full redirect response as I do not want the UserController route exposed
