JWT使用---来源practical-aspnetcore项目

1、配置Setup

        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<JwtIssuerOptions>(options =>
            {
                options.Issuer = "SimpleServer";
                options.Audience = "http://localhost";
                options.SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(Encoding.ASCII.GetBytes("12345678901234567890")), SecurityAlgorithms.HmacSha256);

            });

            services.AddControllersWithViews();
        }

2、生成JWT的输出token

            var claims = new[]
            {
                new Claim(ClaimTypes.Name, "Celon"),
                new Claim(ClaimTypes.Role, "Admin")
            };

            var option = _options.Value;

            var token = new JwtSecurityToken
            (
                issuer: option.Issuer,
                audience: option.Audience,
                claims: claims,
                expires: DateTime.Now.AddMinutes(60),
                signingCredentials: option.SigningCredentials
            );

            var outputToken = new JwtSecurityTokenHandler().WriteToken(token);

3、解析token

            var jwt = new JwtSecurityToken(token);
