.Net5 Swagger开启JWT认证

1、修改Startup.cs文件

2、中间件件注

  app.UseAuthorization();

4、效果

 

 5、代码如下：

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers().AddControllersAsServices();
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new OpenApiInfo { Title = "LTT.API", Version = "v1" });

                //Locate the XML file being generated by ASP.NET...
                var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.XML";
                var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
                //... and tell Swagger to use those XML comments.
                c.IncludeXmlComments(xmlPath);

                #region Swagger开启Jwt认证
                //开启权限小锁
                c.OperationFilter<AddResponseHeadersFilter>();
                c.OperationFilter<AppendAuthorizeToSummaryOperationFilter>();

                //在header中添加token，传递到后台
                c.OperationFilter<SecurityRequirementsOperationFilter>();
                c.AddSecurityDefinition("oauth2", new OpenApiSecurityScheme
                {
                    Description = "JWT授权(数据将在请求头中进行传递)直接在下面框中输入Bearer {token}(注意两者之间是一个空格) "",
                    Name = "Authorization",//jwt默认的参数名称
                    In = ParameterLocation.Header,//jwt默认存放Authorization信息的位置(请求头中)
                    Type = SecuritySchemeType.ApiKey
                });
                #endregion
            });

            //JWT认证
            services.AddAuthentication(options =>
            {
                options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
                options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
            }).AddJwtBearer(options =>
            {
                options.SaveToken = true;
                options.RequireHttpsMetadata = false;
                options.TokenValidationParameters = new TokenValidationParameters()
                {
                    ValidateIssuer = true,
                    ValidateAudience = true,
                    ValidAudience = "https://www.cnblogs.com/chengtian",
                    ValidIssuer = "https://www.cnblogs.com/chengtian",
                    IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("SecureKeySecureKeySecureKeySecureKeySecureKeySecureKey"))
                };
            });
        }

  对了，授权和认证的注入顺序一定不要错了!!!一定是先认证再授权！相当于先知道你是谁然后再确定你有什么权利！
