.NET 6 Swagger+JWT 配置

1.1 封装一个SwaggerExtend类（包含JWT配置）

/// <summary>
    /// Swagger 静态类
    /// </summary>
    public static class SwaggerExtend
    {
        /// <summary>

                options.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());

                options.SwaggerDoc("system_v1", new OpenApiInfo
                {
                    Version = version,

                    Description = $"{apiName} {version} 接口服务"
                });

                //  获取应用程序所在目录
                var basePath = Path.GetDirectoryName(typeof(SwaggerExtend).Assembly.Location);

                //  swagger界面默认只显示 方法&字段 注释，不显示 控制器注释
                //  第二个参数为true， 则是controller的注释
                //options.IncludeXmlComments(xmlPath);
                options.IncludeXmlComments(xmlPath, true);

                options.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme()

                options.AddSecurityRequirement(new OpenApiSecurityRequirement
                {
                    {
                        new OpenApiSecurityScheme
                        {
                            Reference=new OpenApiReference()

                            }
                        },
                       new string[]{}

            services.AddAuthentication(option =>

                option.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
            }).AddJwtBearer(options =>
                {
                    string Jwt_Issuer = "test.cn";
                    string Jwt_Audience = "test";
                    string Jwt_SecretKey = "123456789123456789123456789123456789123456789123456789123456789123456789123456789123456789";

                        ValidateAudience = true,
                        ValidateIssuerSigningKey = true,
                        ValidIssuer = Jwt_Issuer,
                        ValidAudience = Jwt_Audience,
                        IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Jwt_SecretKey))
                    };
                });

        }

        /// <summary>
        /// 添加中间件: swagger
        /// </summary>
        /// <param name="app"></param>
        public static void UseCustSwagger(this IApplicationBuilder app)
        {
            app.UseSwagger();
            app.UseSwaggerUI(options =>
            {
                options.SwaggerEndpoint("/swagger/system_v1/swagger.json", "系统API");
                //  默认路径为：/swagger/index.html
                //  路由前缀 - 设置为空，可直接跳转到swagger页面：/index.html

                // 禁用Swagger UI的自动跳转行为

            });
        }
    }

1.2注入

builder.Services.AddCustSwagger();
/*认证*/
app.UseAuthentication();
/*授权*/
app.UseAuthorization();

1.3 用户登录后返回TOKEN的方法

 private string GenerateJwtToken(T_User user)
        {
            string Jwt_Issuer = "test.cn";
            string Jwt_Audience = "test";
            string Jwt_SecretKey = "123456789123456789123456789123456789123456789123456789123456789123456789123456789123456789";

            var claims = new List<Claim>
            {
                new Claim(ClaimTypes.Name, user.FMobilePhone)
            };

            var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Jwt_SecretKey));
            var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);

            var token = new JwtSecurityToken(
                issuer: Jwt_Issuer,
                audience: Jwt_Audience,
                claims: claims,
                expires: DateTime.UtcNow.AddHours(1),
                signingCredentials: creds);

            return new JwtSecurityTokenHandler().WriteToken(token);
        }
