. Net 7 JWT configuration is too convenient!

Microsoft announces .NET 7 preview5 There are some big improvements , Include JWT Simplified and automated authentication configuration .

I installed. preview 5 Tried a new JWT Identity configuration . If you want to update an existing project to .Net 7 preview 5, Here is a quick update command .

Update all Microsoft.AspNetCore.* package references to 7.0.0-preview.5.*.
Update all Microsoft.Extensions.* package references to 7.0.0-preview.5.*.

  .NET 7 Previous JWT Authentication configuration   

Microsoft says it has received feedback , stay ASP.NET Core Configuration in the project JWT, It's writing API Is one of the hardest parts . It takes many steps , This includes adding middleware and configuring services during startup .

.Net The team knows JWT Configure in protection API The importance of , That's why they have improved and simplified the ASP.NET Core Configuration in the project JWT The process of Authentication .

  A simplified JWT To configure   

WebApplicationBuilder Added a new Authentication attribute , You can then call AddJwtBearer() Method , as follows

var builder = WebApplication.CreateBuilder(args);
builder.Authentication.AddJwtBearer();  
var app = builder.Build();

Use this new property to set JWT Authentication automatically adds the required middleware , No additional code is required .

most important of all , Now you can directly appsettings.json To configure JWT, You can easily configure multiple environments .

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "Authentication": {
    "DefaultScheme" : "JwtBearer",
    "Schemes": {
      "JwtBearer": {
        "Audiences": [ "http://localhost:5000", 
                      "https://localhost:5001" ],
        "ClaimsIssuer": "user-jwt-here"
      }
    }
  }
}

Above is .NET 7 preview 5 Simplified in JWT To configure , This is very convenient , This improvement can really help developers save time on configuring projects .
