依赖包：
netcoreapp3.1
IdentityModel 4.1.1
Swashbuckle.AspNetCore 5.0.0
Microsoft.AspNetCore.Authentication.JwtBearer 3.1.1

登录是依赖于IdentityServer4。
客户端是API项目，使用了.NET Core 3.1，安装了Swagger做接口ui。
如下为API项目的Startup.cs文件内容：

 public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { services.AddRepoExtentions(Configuration); services.AddControllers(); services.AddAuthentication("Bearer") .AddJwtBearer("Bearer", options => { options.Authority = "https://localhost:5001"; options.RequireHttpsMetadata = false; options.Audience = "api1"; }); services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" }); var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml"; var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile); c.IncludeXmlComments(xmlPath,true); //添加控制器层注释（true表示显示控制器注释） c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme { Description = "JWT授权(数据将在请求头中进行传输) 直接在下框中输入Bearer {token}（注意两者之间是一个空格）\"", Name = "Authorization", In = ParameterLocation.Header, Type = SecuritySchemeType.ApiKey, BearerFormat = "JWT", Scheme = "Bearer" }); c.AddSecurityRequirement(new OpenApiSecurityRequirement() { { new OpenApiSecurityScheme { Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "Bearer" } }, new string[] { } } }); }); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.UseHttpsRedirection(); app.UseRouting(); app.UseAuthentication(); app.UseAuthorization(); app.UseSwagger(); app.UseSwaggerUI(c => { c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1"); }); app.UseEndpoints(endpoints => { endpoints.MapControllers(); }); } }

其中xml备注需要单独开启如下配置：
