问题 In .NET Core 2 Web API app, I could override configuration urls using appsettings.json , but in the official docs they introduced extra file "hosting.json", Why?

My expectation is to see the image in the browser.

Looking for a solution My Web API is as

问题 I am porting my API from Web API 2 to ASP.NET Core Web API. I used to be able to add a custom header in the following manner: HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK); response.Headers.Add("X-Total-Count", count.ToString()); return ResponseMessage(response); How does one add a custom header in ASP.NET Core Web API? 回答1: You can just hi-jack the HttpContext from the incoming Http Request and add your own custom headers to the Response object before calling

问题 I have a console application written in .NET Core 2.2.6 that is using Kestrel to host a simple WebApi. public class SettingsController : Controller { // // GET: /settings/ public string Index() { return $"Hello world! controller"; } } If I publish the code and run the executable, I can visit http://127.0.0.1:310/settings and see the expected "Hello world! controller". However, if I debug (or even open in Release mode) from inside Visual Studio 2019, the same URL throws a 404 exception. Some

问题 I've seen a lot of ASP.NET Core Web API projects that use the default AddMvc() service without the realizing that using AddMvcCore() is a superior option due to the control over services. How exactly do you implement an ASP.NET Core Web API by using AddMvcCore() and why is it better? 回答1: What is the difference between AddMvc() and AddMvcCore() ? The first thing key thing to understand is that AddMvc() is just a pre-loaded version of AddMvcCore() . You can see the exact implementation of the

问题 I'm trying to make a simple API call from a .NET Core MVC application: using (var client = new HttpClient()) { client.BaseAddress = new Uri("http://localhost:49897"); var response = client.GetAsync("some-route").Result; var dataString = response.Content.ReadAsStringAsync().Result; // Unexpected data here. See below. [...] // deserialize dataString } client.GetAsync(route) successfully hits an API action method, which ultimately does this: public HttpResponseMessage Get([FromUri] BindingModel
