视频教程（使用+实现原理）：https://share.weiyun.com/57HKopT 建议直接看视频
源码地址：https://github.com/bxjg1987/abpGeneralModules
库版本.net core 3.1
我的abp版本：abp5.3 .net core 3.1
请先看微信小程序官方文档。下面说说abp中如何使用。原生asp.net core可以参考实现
服务端配置
1、安装nuget包
Install-Package BXJG.WeChart -Version 1.0.0
2、修改配置文件 abp.web.host/appsettings.json
3、修改启动配置类abp.web.host//StartupAuthConfigurer.cs
因为startup中是通过这个类中的静态方法注册身份验证相关服务的
1 public static void Configure(IServiceCollection services, IConfiguration configuration) 2 { 3 var authBuilder = services.AddAuthentication(options => 4 { 5 options.DefaultAuthenticateScheme = "JwtBearer"; 6 options.DefaultChallengeScheme = "JwtBearer"; 7 }); 8 9 if (bool.Parse(configuration["Authentication:JwtBearer:IsEnabled"]))10 {11 authBuilder.AddJwtBearer("JwtBearer", options =>12 {13 options.Audience = configuration["Authentication:JwtBearer:Audience"];14 15 options.TokenValidationParameters = new TokenValidationParameters16 {17 // The signing key must match!18 ValidateIssuerSigningKey = true,19 IssuerSigningKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(configuration["Authentication:JwtBearer:SecurityKey"])),20 21 // Validate the JWT Issuer (iss) claim22 ValidateIssuer = true,23 ValidIssuer = configuration["Authentication:JwtBearer:Issuer"],24 25 // Validate the JWT Audience (aud) claim26 ValidateAudience = true,27 ValidAudience = configuration["Authentication:JwtBearer:Audience"],28 29 // Validate the token expiry30 ValidateLifetime = true,31 32 // If you want to allow a certain amount of clock drift, set that here33 ClockSkew = TimeSpan.Zero34 };35 36 options.Events = new JwtBearerEvents37 {38 OnMessageReceived = QueryStringTokenResolver39 };40 });41 }42 43 if (bool.Parse(configuration["Authentication:WeChartMiniProgram:IsEnabled"]))44 {45 authBuilder.AddWeChartMiniProgram(opt =>46 {47 opt.AppId = configuration["Authentication:WeChartMiniProgram:AppId"];48 opt.Secret = configuration["Authentication:WeChartMiniProgram:Secret"];49 50 opt.ClaimActions.MapJsonKey("nickName", "nickName");51 opt.ClaimActions.MapJsonKey("avatarUrl", "avatarUrl");52 opt.ClaimActions.MapJsonKey("gender", "gender");53 opt.ClaimActions.MapJsonKey("country", "country");54 opt.ClaimActions.MapJsonKey("province", "province");55 opt.ClaimActions.MapJsonKey("city", "city");56 opt.ClaimActions.MapJsonKey("language", "language");57 });58 }59 }更多配置请参考视频
4、实现abp集成
找到abp.web.core/controllers/TokenAuthController
先注入UserManager
然后添加下面的方法
1 [HttpPost] 2 public async Task WeChartMiniProgramLoginAsync() 3 { 4 5 //从第三方登录拿到当前用户（包含openId、sessionKey） 6 var t = await base.HttpContext.AuthenticateAsync(MiniProgramConsts.AuthenticationScheme);//间接使用第三方身份验证方案获取信息 7 //拿到openId 8 var openid = t.Principal.Claims.Single(c => c.Type == ClaimTypes.NameIdentifier).Value; 9 var tenancyName = GetTenancyNameOrNull();10 //尝试做第三发登录（内部通过openid找到本地账号做登录），11 var loginResult = await _logInManager.LoginAsync(new UserLoginInfo(MiniProgramConsts.AuthenticationScheme, openid, MiniProgramConsts.AuthenticationSchemeDisplayName), tenancyName);12 //根据登录结果，若成功则直接返回jwtToken 或者自动注册后返回13 switch (loginResult.Result)14 {15 case AbpLoginResultType.Success:16 {17 //更新微信用户信息18 foreach (var item in t.Principal.Claims)19 {20 await userManager.ReplaceClaimAsync(loginResult.User, new Claim(item.Type, ""), item);21 }22 23 //返回jwtToken24 var accessToken = CreateAccessToken(CreateJwtClaims(loginResult.Identity));25 return new ExternalAuthenticateResultModel26 {27 AccessToken = accessToken,28 EncryptedAccessToken = GetEncryptedAccessToken(accessToken),29 ExpireInSeconds = (int)_configuration.Expiration.TotalSeconds30 };31 }32 case AbpLoginResultType.UnknownExternalLogin:33 {34 //若未找到关联的本地账号则自动注册，再返回jwtToken35 var newUser = await RegisterExternalUserAsync(new ExternalAuthUserInfo36 {37 Provider = MiniProgramConsts.AuthenticationScheme,38 ProviderKey = openid,39 Name = t.Principal.Claims.SingleOrDefault(c => c.Type == "nickName")?.Value,40 EmailAddress = Guid.NewGuid().ToString("N") + "@mp.com",41 Surname = "a"42 });43 if (!newUser.IsActive)44 {45 return new ExternalAuthenticateResultModel46 {47 WaitingForActivation = true48 };49 }50 51 // Try to login again with newly registered user!52 loginResult = await _logInManager.LoginAsync(new UserLoginInfo(MiniProgramConsts.AuthenticationScheme, openid, MiniProgramConsts.AuthenticationSchemeDisplayName), tenancyName);53 if (loginResult.Result != AbpLoginResultType.Success)54 {55 throw _abpLoginResultTypeHelper.CreateExceptionForFailedLoginAttempt(56 loginResult.Result,57 openid,58 tenancyName59 );60 }61 //保存微信用户信息（排出openid，因为它存储在userlogins里）62 await userManager.AddClaimsAsync(loginResult.User, t.Principal.Claims.Where(c=>c.Type!= ClaimTypes.NameIdentifier));63 64 return new ExternalAuthenticateResultModel65 {66 AccessToken = CreateAccessToken(CreateJwtClaims(loginResult.Identity)),67 ExpireInSeconds = (int)_configuration.Expiration.TotalSeconds68 };69 }70 default:71 {72 throw _abpLoginResultTypeHelper.CreateExceptionForFailedLoginAttempt(73 loginResult.Result,74 openid,75 tenancyName76 );77 }78 }79 }
小程序端处理
小程序调用wx.login拿到code，然后调用wx.getUserInfo拿到用户昵称、头像、性别.....等数据
将上面的数据组成json Post提交到 我方服务器/wechart-miniProgram-signin
此时会返回一个加密的cookie字符串，小程序端需要想法从响应的cookie中拿到此字符串
用上面的字符串作为cookie Post请求 我方服务器/api/TokenAuth/WeChartMiniProgramLogin
此时服务端会返回jwtToken
后续请求跟之前的处理就一样了。
