创建CustomAuthCodeValidator类

public class CustomAuthCodeValidator : IExtensionGrantValidator
{
    private readonly UserManager<IdentityUser> _userManager;
    public CustomAuthCodeValidator(UserManager<IdentityUser> userManager)
    {
        _userManager = userManager;
    }
    public string GrantType => "auth_custom";
    public async Task ValidateAsync(ExtensionGrantValidationContext context)
    {
        var name = context.Request.Raw["name"];
        var age = context.Request.Raw["age"];
        // 创建无效授权的返回实例
        var errorValidationResult = new GrantValidationResult(TokenRequestErrors.InvalidGrant);
        // 判断name参数与age参数是否为空
        if (string.IsNullOrWhiteSpace(name) || string.IsNullOrWhiteSpace(age))
        {
            // 赋予无效授权结果
            context.Result = errorValidationResult;
            return;
        }
        if (name!="bob" && age!="19")
        {
            // 赋予无效授权结果
            context.Result = errorValidationResult;
            return;
        }
        // 获取到有效的用户 subject_id
        var user = await _userManager.FindByNameAsync(name);
        // 返回有效结果
        context.Result = new GrantValidationResult(user.Id, GrantType);
    }
}

在Startup.cs中实现自定义验证

.AddExtensionGrantValidator<CustomAuthCodeValidator>()

输入相对应的请求参数进行测试
