问题 I am struggling a bit with how the appsettings.Development.json overrides or otherwise merges with the appsettings.json . I am not sure how to "clear" a node out of appsettings.json by using the appsettings.Development.json file. For reference, I am using the default builder as seen here https://github.com/aspnet/MetaPackages/blob/rel/2.0.0-preview1/src/Microsoft.AspNetCore/WebHost.cs#L159-L160 appsettings.json { "Policy": { "roles": [ { "name": "inventoryAdmin", "subjects": [ "bob", "alice"

问题 I'm having the following code on the client side: fetch("/music/index", { headers: { "Content-Type": "application/json" } }) .then(response => { if (!response.ok) { throw response; } return response.json(); }) .then(json => { console.log("Done! It's all good"); }) .catch(response => console.log(response)); Unfortunately this doesn't even reach the MusicController (server-side), which looks as follows (simplified to illustrate the point): [Authorize] public class MusicController : Controller {

问题 As I was adding swagger to my API, I wanted to get default values and response examples. I added the NuGet packages and tried to follow this tutorial. The SwaggerResponseExample attribute works properly but the SwaggerRequestExample seems to be simply ignored. With my action defined as follow [SwaggerRequestExample(typeof(int), typeof(PersonExamples.Request))] [SwaggerResponseExample(200, typeof(PersonExamples.Response))] /* more attribute & stuff */ public IActionResult Get(int id) { /*

问题 I am playing around with Amazon Cognito and after reading some of the docs and creating a user pool I am running into some issues. I believe that a cognito user pool can be used with OpenId to redirect the user to a hosted UI for user authentication (without federating out to another provider). I have tried to use the authentication options in DotNetCore 2 to do this as this is something I have done previous with other providers. I have the following: services.AddAuthentication(options => {

问题 On which is running the WebService. Like the one I can get in cmd.exe > ipconfig : What I would like to achieve is automatic IP configuration of Kestrel, like: .UseKestrel(opts => { opts.Listen(/*LocalIPv4ActiveAddress*/, 5000); }) So I can switch my development machines with different active network interfaces (WiFi || Ethernet) and different local network IP addresses. 回答1: You can try something like this: // order interfaces by speed and filter out down and loopback // take first of the

问题 I have a controller EBisUserController which contains a public property ConnectionString obtained from appsettings.json through dependency injection. The controller has an attribute filter 'EBisUserAuthResourceFilter' requiring use of the property ConnectionString found in the controller. What is the most performant method to access ConnectionString. I have a working example of what I want, but know this is not the correct way of doing this as it must open and read the file for each

问题 I'm getting the following exception in my custom database initializer class: System.ObjectDisposedException occurred HResult=0x80131622 Message=Cannot access a disposed object. A common cause of this error is disposing a context that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling Dispose() on the context, or wrapping the context in a using statement. If you are using dependency

问题 I start to develop an web application with .net core 2 and web service.. when a user registers on the site, he can choose whether he is a company or a simple user, so I store the data in a specific table but the login data are stored in AspNetUsers.
