问题 I am trying to implement response caching in my web api using the "Microsoft.AspNetCore.ResponseCaching" package. I am using Postman to test the application and validate headers etc. The correct headers are generated with the specified max-age but postman seems to request the response from the api and not using the cache. The response time does not vary at all and if I debug the controller I can see that it gets hit by the request every time. Startup class ConfigureServices (along with other

问题 I make multiple calls to a Web API during login operations in IdentityServer4. Same applies during password reset operations which is custom code I have added to the IdentityServer4 project. So how should I protect my ASP.NET Core Web API when the user isn't yet authenticated via OIDC which implies that there also isn't exist any access token at that stage. I would like to only allow IdentityServer4 to call these Web API methods instead of running unprotected Web API's. Any suggestions? 回答1:

问题 I'm working on a Web API and I am not sure if I did a mistake by avoiding using the Identity membership system and implementing my own authentication setup. From what I've read it looks like it's a great solution for frontend-ish logins such as Facebook where you can use UserManager to easily commit different CRUD's on users, etc but I've also seen it being used by other people for their Web API's.

For those cases, I implemented policies like this in the Startup.cs file: var name = "PolicyNameIndicatingGroup"; var id = Guid.NewGuid; // Actually, this is set to the object ID of the group in AD. services

问题 I have an ASP .Net Core 2.1 Web Api. I was wondering if there is an "elegant solution" for constructing filters on my DbContext based on query strings? So... say I have one [optional] query string: // GET: api/Accounts [HttpGet] public IEnumerable<File> GetAccount([FromQuery] bool? isActive) { if (isActive.HasValue) return _context.Accounts.Where(a => a.IsActive == isActive.Value); else return _context.Accounts; } Simple enough... But say I have a number of (optional) query strings: // GET:

问题 I'm interested in what is approach for storing of sensitive data in cloud in your projects. I want to prepare proof of concept of feature which have to archive files in Azure. We are talking about samething around 30GB of new files per day. 10-2000 MB per file. My first idea was to use Azure Storage to store those files.

问题 I have a simple Angular form which I want to post a Loan object to a .net core web API. After submitting the form I can see this data in the console: Object { Id: 0, BorrowerName: "asd", RepaymentAmount: 11.5, FundingAmount: 10 } But my API action never gets called.
