In .NET Core 3.0, the AddJwtBearer
extension method was replaced by AddAuthentication
and AddJwtBearer
methods. Here's an example of how to configure JWT authentication in .NET Core 3.0:
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme) .AddJwtBearer(options => { options.TokenValidationParameters = new TokenValidationParameters { ValidateIssuer = true, ValidateAudience = true, ValidateLifetime = true, ValidateIssuerSigningKey = true, ValidIssuer = Configuration["Jwt:Issuer"], ValidAudience = Configuration["Jwt:Audience"], IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Jwt:Key"])) }; });
The AddAuthentication
method sets up authentication for the application, while AddJwtBearer
adds JWT bearer token authentication. The options
parameter is used to configure the JWT bearer authentication options, including the token validation parameters.
".NET Core 3.0 replace AddJwtBearer with AddJwtBearerAuthentication"
AddJwtBearer
authentication extension with AddJwtBearerAuthentication
in .NET Core 3.0.// Code to replace AddJwtBearer with AddJwtBearerAuthentication services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication(options => { // Configuration for JwtBearerAuthentication });
".NET Core 3.0 JwtBearerAuthentication extension configuration"
AddJwtBearer
in .NET Core 3.0.// Code for configuring JwtBearerAuthentication extension services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication(options => { options.TokenValidationParameters = new TokenValidationParameters { // Token validation parameters }; });
".NET Core 3.0 update JwtBearerOptions with JwtBearerAuthentication"
AddJwtBearer
to AddJwtBearerAuthentication
in .NET Core 3.0.// Code to update JwtBearerOptions with JwtBearerAuthentication services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication(options => { // Update JwtBearerOptions properties options.RequireHttpsMetadata = false; });
".NET Core 3.0 change authentication scheme with JwtBearerAuthentication"
AddJwtBearer
with AddJwtBearerAuthentication
in .NET Core 3.0.// Code to change authentication scheme with JwtBearerAuthentication services.AddAuthentication(options => { options.DefaultScheme = "CustomJwtScheme"; }) .AddJwtBearerAuthentication("CustomJwtScheme", options => { // Configuration for CustomJwtScheme });
".NET Core 3.0 JwtBearerAuthentication events and callbacks"
AddJwtBearer
in .NET Core 3.0.// Code for handling events and callbacks with JwtBearerAuthentication services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication(options => { options.Events = new JwtBearerAuthenticationEvents { // Configure events and callbacks }; });
".NET Core 3.0 JwtBearerAuthentication validation parameters"
AddJwtBearer
in .NET Core 3.0.// Code for configuring token validation parameters with JwtBearerAuthentication services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication(options => { options.TokenValidationParameters = new TokenValidationParameters { // Token validation parameters }; });
".NET Core 3.0 JwtBearerAuthentication save token"
// Code for saving JWT token with JwtBearerAuthentication services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication(options => { options.SaveToken = true; });
".NET Core 3.0 JwtBearerAuthentication configuration with named options"
// Code for configuring JwtBearerAuthentication with named options services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication("CustomJwtScheme", options => { // Configuration for CustomJwtScheme });
".NET Core 3.0 JwtBearerAuthentication authority and audience"
AddJwtBearer
in .NET Core 3.0.// Code for configuring authority and audience with JwtBearerAuthentication services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication(options => { options.Authority = "https://example.com"; options.Audience = "api"; });
".NET Core 3.0 JwtBearerAuthentication additional token validation"
AddJwtBearer
in .NET Core 3.0.// Code for additional token validation with JwtBearerAuthentication services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }) .AddJwtBearerAuthentication(options => { options.TokenValidationParameters = new TokenValidationParameters { // Additional token validation parameters }; });
