一、鉴权和授权（grpc专栏结束后会开启鉴权授权专栏欢迎大家关注）

权限认证这里使用IdentityServer4配合JWT进行认证
通过AddAuthentication和AddAuthorization方法进行鉴权授权注入；通过UseAuthentication和UseAuthorization启用鉴权授权
增加授权策略处理
使用密码模式，及简易内存处理
生成token带入grpc的metadata进行传递
服务端对应的方法标记特性[Authorize]进行验证
代码中会有对应的注释说明，如果对您有用，可静下心来细致的浏览

二、实战案例

需要一个授权中心服务
需要一个gRPC后端服务
需要一个客户端调用对应的授权中心和gRPC后端服务

第一步：授权中心

1）引入IdentityServer4包

2）添加IdentityServer注入及启用IdentityServer

// 添加IdentityServer4注入// 注入id4服务 配置开发证书 配置内存客户端client
builder.Services.AddIdentityServer().AddDeveloperSigningCredential().AddInMemoryClients(PasswordInfoConfig.GetClients()).AddInMemoryApiResources(PasswordInfoConfig.GetApiResources()).AddInMemoryApiScopes(PasswordInfoConfig.GetApiScopes()).AddTestUsers(PasswordInfoConfig.GetUsers());// 启用IdentityServer 同时启用认证和授权app.UseIdentityServer();
app.UseAuthentication();app.UseAuthorization();

3）密码在程序中进行了初始化；因为是模拟，这里就没有放到数据库

    public class PasswordInfoConfig{/// <summary>/// 获取设定客户端/// </summary>/// <returns></returns>public static IEnumerable<Client> GetClients(){return new[] {new Client{ClientId="laoliu",ClientSecrets= new []{ new Secret("laoliu123456".Sha256()) },AllowedGrantTypes = GrantTypes.ResourceOwnerPassword,AllowedScopes = new[] {"TestApi","UserApi"},Claims = new List<ClientClaim>(){new ClientClaim(JwtClaimTypes.Role,"Admin"),new ClientClaim(JwtClaimTypes.NickName,"王先生"),new ClientClaim(JwtClaimTypes.Email,"88@163.com")}}};}/// <summary>/// 获取Api对应的作用域/// </summary>/// <returns></returns>public static IEnumerable<ApiScope> GetApiScopes(){return new[] { new ApiScope("UserApi", "用户作用域"), new ApiScope("TestApi", "测试作用域") };}/// <summary>/// 获取Api资源/// </summary>/// <returns></returns>public static IEnumerable<ApiResource> GetApiResources(){return new[]{new ApiResource("TestApi","测试的API",new List<string>{ IdentityModel.JwtClaimTypes.Role,"email"}){Scopes = new List<string> { "TestApi" }},new ApiResource("UserApi","用户的API",new List<string>{ JwtClaimTypes.NickName,"email"}){Scopes= new List<string> { "UserApi" }}};}public static List<TestUser> GetUsers(){return new List<TestUser>{new TestUser(){Username="admin",Password="password",SubjectId="0",Claims= new List<Claim>(){new Claim(JwtClaimTypes.Role,"Admin"),new Claim(JwtClaimTypes.NickName,"陈先生"),new Claim(JwtClaimTypes.Email,"77.com")}}};}}

第二步：gRPC后端服务

1）引入IdentityServer4、IdentityServer4.AccessTokenValidation、Microsoft.AspNetCore.Authentication.JwtBearer包

2）添加IdentityServer权限解析认证

3）启用鉴权和授权

4）对应的类或方法中标记 [Authorize]

4）GRPC的服务及Proto文件这里不贴上来了有需要可以直接百度云盘下载源码查看

// 注入
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddIdentityServerAuthentication(options =>{// 权限中心 服务地址options.Authority = "http://localhost:5172";options.ApiName = "TestApi";options.RequireHttpsMetadata = false;});builder.Services.AddAuthorization();
builder.Services.AddGrpc();// 启用app.UseAuthentication();
app.UseAuthorization();// 字段
app.MapGrpcService<ProtoFieldService>();

// 基础配置
[Authorize]
public override async Task<Empty> BaseConfigService(BaseConfig request, ServerCallContext context)
{await Console.Out.WriteLineAsync("\r\n--------------------------基础配置--------------------------\r\n");// 打印字段信息var properties = request.GetType().GetProperties();foreach (var property in properties){var value = property.GetValue(request);await Console.Out.WriteLineAsync($"{property.Name}：{value}");}return new Empty();
}

第三步：WPF客户端

1）调用鉴权中心获取token

2）gRPC工厂中配置token传递或者在调用对应的客户端函数中对metadata传参

3）调用

    public class WpfAuthClient{private static string _token = null;public static async Task<string> GetToken(){if (_token != null){return _token;}var client = new HttpClient();PasswordTokenRequest tokenRequest = new PasswordTokenRequest();tokenRequest.Address = "http://localhost:5172/connect/token";tokenRequest.GrantType = GrantType.ResourceOwnerPassword;tokenRequest.ClientId = "laoliu";tokenRequest.ClientSecret = "laoliu123456";tokenRequest.Scope = "TestApi";tokenRequest.UserName = "admin";tokenRequest.Password = "password";var tokenResponse = await client.RequestPasswordTokenAsync(tokenRequest);var token = tokenResponse.AccessToken;var tokenType = tokenResponse.TokenType;_token = $"{tokenType} {token}";return _token;}}

    public static class GrpcClient{/// <summary>/// rpc 工厂注入/// </summary>/// <param name="services"></param>/// <returns></returns>public static IServiceCollection AddWPFGrpc(this IServiceCollection services){if (services == null){throw new ArgumentNullException(nameof(services));}services.AddGrpcClient<FieldRpc.FieldRpcClient>(options =>{options.Address = new Uri("https://localhost:7188");}).AddCallCredentials(async (context, metadata) =>{var token = await WpfAuthClient.GetToken();metadata.Add("Authorization", token);});return services;}}
