No authenticationScheme was specified, and there was no DefaultChallengeScheme found.
Hello, there! I added JWT Authentication to my ASP.NET Core Web API project by this code snipper:
Then, when I'm requesting any endpoint that requires authorization, asp.net core throws an exception:
What am I doing wrong?
builder.Services.AddAuthentication(a =>
{
a.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
a.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
a.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer("jwt", o =>
{
o.TokenValidationParameters = new TokenValidationParameters()
{
ValidIssuer = config["Jwt:Issuer"],
ValidAudience = config["Jwt:Audience"],
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(config["Jwt:Key"]!)),
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true
};
});builder.Services.AddAuthentication(a =>
{
a.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
a.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
a.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer("jwt", o =>
{
o.TokenValidationParameters = new TokenValidationParameters()
{
ValidIssuer = config["Jwt:Issuer"],
ValidAudience = config["Jwt:Audience"],
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(config["Jwt:Key"]!)),
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true
};
});Then, when I'm requesting any endpoint that requires authorization, asp.net core throws an exception:
