很多同学说AgileConfig的UI实在是太丑了。我想想也是的，本来这个项目是我自己使用的，一开始甚至连UI都没有，全靠手动在数据库里修改数据。后来加上了UI也是使用了老掉牙的bootstrap3做为基础样式。前台框架也是使用了angularjs，同样是老掉牙的东西。过年期间终于下决心翻新AgileConfig的前端UI。最后选择的前端UI框架为AntDesign Pro + React。至于为啥选Ant-Design Pro是因为他好看，而且流行，选择React是因为VUE跟Angular我都略知一二，干脆趁此机会学一学React为何物，为何这么流行。
登录的认证方案为JWT，其实本人对JWT不太感冒（请看这里《我们真的需要jwt吗？》），无奈大家都喜欢，那我也只能随大流。
其实基于ant-design pro的界面我已经翻的差不多了，因为它支持mock数据，所以我一行后台代码都没修改，已经把界面快些完了。从现在开始要真正的跟后端代码进行联调了。那么我们先从登录开始吧。先看看后端asp.net core方面会如何进行修改。
在appsettings.json文件添加jwt相关配置。
public class JwtSetting { static JwtSetting() { Instance = new JwtSetting(); Instance.Audience = Global.Config["JwtSetting:Audience"]; Instance.SecurityKey = Global.Config["JwtSetting:SecurityKey"]; Instance.Issuer = Global.Config["JwtSetting:Issuer"]; Instance.ExpireSeconds = int.Parse(Global.Config["JwtSetting:ExpireSeconds"]); } public string SecurityKey { get; set; } public string Issuer { get; set; } public string Audience { get; set; } public int ExpireSeconds { get; set; } public static JwtSetting Instance { get; } }定义一个JwtSetting类，用来读取配置。
public void ConfigureServices(IServiceCollection services) { services.AddMemoryCache(); services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme) .AddJwtBearer(options => { options.TokenValidationParameters = new TokenValidationParameters { ValidIssuer = JwtSetting.Instance.Issuer, ValidAudience = JwtSetting.Instance.Audience, IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(JwtSetting.Instance.SecurityKey)), }; }); services.AddCors(); services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_3_0).AddRazorRuntimeCompilation(); services.AddFreeSqlDbContext(); services.AddBusinessServices(); services.AddAntiforgery(o => o.SuppressXFrameOptionsHeader = true); }修改Startup文件的ConfigureServices方法，修改认证Scheme为JwtBearerDefaults.AuthenticationScheme，在AddJwtBearer方法内配置jwt相关配置信息。因为前后端分离项目所以有可能api跟ui部署在不同的域名下，所以开启Core。
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IServiceProvider serviceProvider) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } else { app.UseMiddleware<ExceptionHandlerMiddleware>(); } app.UseCors(op=> { op.AllowAnyOrigin(); op.AllowAnyMethod(); op.AllowAnyHeader(); }); app.UseWebSockets(new WebSocketOptions() { KeepAliveInterval = TimeSpan.FromSeconds(60), ReceiveBufferSize = 2 * 1024 }); app.UseMiddleware<WebsocketHandlerMiddleware>(); app.UseStaticFiles(); app.UseRouting(); app.UseAuthentication(); app.UseAuthorization(); app.UseEndpoints(endpoints => { endpoints.MapDefaultControllerRoute(); }); }修改Startup的Configure方法，配置Cors为Any。
public class JWT { public static string GetToken() { //创建用户身份标识，可按需要添加更多信息 var claims = new Claim[] { new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString()), new Claim("id", "admin", ClaimValueTypes.String), // 用户id new Claim("name", "admin"), // 用户名 new Claim("admin", true.ToString() ,ClaimValueTypes.Boolean) // 是否是管理员 }; var key = Encoding.UTF8.GetBytes(JwtSetting.Instance.SecurityKey); //创建令牌 var token = new JwtSecurityToken( issuer: JwtSetting.Instance.Issuer, audience: JwtSetting.Instance.Audience, signingCredentials: new SigningCredentials(new SymmetricSecurityKey(key), SecurityAlgorithms.HmacSha256Signature), claims: claims, notBefore: DateTime.Now, expires: DateTime.Now.AddSeconds(JwtSetting.Instance.ExpireSeconds) ); string jwtToken = new JwtSecurityTokenHandler().WriteToken(token); return jwtToken; } }添加一个JWT静态类用来生成jwt的token。因为agileconfig的用户只有admin一个所以这里用户名，ID都直接写死。
[HttpPost("admin/jwt/login")] public async Task<IActionResult> Login4AntdPro([FromBody] LoginVM model) { string password = model.password; if (string.IsNullOrEmpty(password)) { return Json(new { status = "error", message = "密码不能为空" }); } var result = await _settingService.ValidateAdminPassword(password); if (result) { var jwt = JWT.GetToken(); return Json(new { status="ok", token=jwt, type= "Bearer", currentAuthority = "admin" }); } return Json(new { status = "error", message = "密码错误" }); }
