在asp.net core 3.0中开启identity认证
asp.net core 3.0种需要导入的identity包与core 2.2发生了些变化：
<ItemGroup> <PackageReference Include="Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore" Version="3.0.0-preview5-19227-01" /> <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.0.0-preview5-19227-01" /> <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="3.0.0-preview5-19227-01" /> <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="3.0.0-preview5-19227-01" /> <PackageReference Include="Microsoft.AspNetCore.Mvc.NewtonsoftJson" Version="3.0.0-preview5-19227-01" /> <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.0.0-preview5.19227.1" /> <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.0.0-preview5.19227.1" /> </ItemGroup>
代码的配置方式变化不大，主要集中在ConfigureServices中：
services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))); services .AddDefaultIdentity<IdentityUser>(delegate (IdentityOptions options) { options.Password.RequiredLength = 6; options.Password.RequireLowercase = false; options.Password.RequireUppercase = false; options.Password.RequireNonAlphanumeric = false; options.Password.RequireDigit = false; }) .AddEntityFrameworkStores<ApplicationDbContext>(); services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme) .AddJwtBearer(options => { options.TokenValidationParameters = new TokenValidationParameters { LifetimeValidator = (before, expires, token, param) => expires > DateTime.UtcNow, ValidateAudience = false, ValidateIssuer = false, ValidateActor = false, ValidateLifetime = true, IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("41B71F9E-4204-4E88-8E91-64B1981F1B82")) }; });
在asp.net core 3.0中同时集成gRPC与Restful API
在Kestrel中同时支持HTTP1与HTTP2：
public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureWebHostDefaults(webBuilder => { webBuilder .ConfigureKestrel(options => { options.ListenLocalhost(50051, listenOptions => { listenOptions.UseHttps("server.pfx", "1111"); listenOptions.Protocols = HttpProtocols.Http1AndHttp2; }); }) .UseStartup<Startup>(); });
需要特别注意的一点，关于Kestrel的文档有提到，同时开启Http1与Http2需要TLS和ALPN导向HTTP/2，否则默认在HTTP1.1。
基于Bearer Token的gRPC服务授权
gRPC集成到asp.net core3.0之后，默认的授权方式可以直接使用在gRPC服务上：
[Authorize(AuthenticationSchemes = "Bearer")] public class GreeterService : Greeter.GreeterBase { public override Task<HelloReply> SayHello(HelloRequest request, ServerCallContext context) { return Task.FromResult(new HelloReply { Message = "Hello " + request.Name }); } }
