LineAuthentication for ASP.NET Core

LineAuthentication provides LINE authentication like Twitter, Facebook, and other external login. Supports LINE Profile+.

Support Platforms

• .NET 8+

How to use

It is very easy to use, just call AddLine() which is an extension method of AuthenticationBuilder. This API style is same of other external login, so you never confuse.

services
    .AddAuthentication()
    .AddLine(options =>
    {
        options.ClientId = Configuration["Authentication:Line:ChannelId"];
        options.ClientSecret = Configuration["Authentication:Line:ChannelSecret"];
    });

To access the LINE Profile+, add an authorization scope and extract the data from the JSON payload.

services
    .AddAuthentication()
    .AddLine(options =>
    {
        // ...

        // Add authorization scopes
        options.Scope.Add("real_name");
        options.Scope.Add("gender");
        options.Scope.Add("birthdate");
        options.Scope.Add("address");
        options.Scope.Add("phone");
        options.Scope.Add("email");

        // Map JSON payload to claims
        options.ClaimActions.MapJsonKey(ClaimTypes.Email, "email");

        // Access entire JSON payload
        options.Events.OnCreatingTicket = context =>
        {
            var json = context.User.GetRawText();
            return Task.CompletedTask;
        };
    });
