surging 社区版本支持.net core 3.1
fanly11 人气:1简介
surging 经过两年多的研发,微服务引擎已经略有雏形,也承蒙各位的厚爱, GitHub上收获了将近2800星,fork 811,付费用户企业也有十几家,还有咨询培训,
在2020年,我们将依靠社区的力量,去完善社区版本,更会花更多的精力去维护好付费用户,大家一起把surging 的社区建设好,还有十几天就要过年,大家可以加入surging唯一官方群:615562965, 过年的时候会和往常一样发红包,而且不少哦。让我们过年狂欢起来。
surging 将会有自己的官方站,作者正在用VuePress进行研发,在不久的日子将会和大家见面
新功能简述
1.GRPC协议支持:
添加接口,将ServerCallContext参数的默认值设置为null。 代码如下:
using Greet; using Grpc.Core; using Surging.Core.CPlatform.Ioc; using Surging.Core.CPlatform.Runtime.Server.Implementation.ServiceDiscovery.Attributes; using System.Threading.Tasks; namespace Surging.IModuleServices.Common { [ServiceBundle("api/{Service}/{Method}")] public interface IGreeterService : IServiceKey { Task<HelloReply> SayHello(HelloRequest request, ServerCallContext context=null); } }
添加GreeterBehavior,代码如下
using Greet; using Surging.Core.CPlatform.Ioc; namespace Surging.Modules.Common.GreeterServices { public partial class GreeterBehavior : Greeter.GreeterBase,IServiceBehavior { } }
添加业务代码,代码如下:
using Greet; using Grpc.Core; using Surging.IModuleServices.Common; using Surging.Modules.Common.GreeterServices; using System.Threading.Tasks; namespace Surging.Modules.Common.Domain { public class GreeterService: GreeterBehavior, IGreeterService { public override Task<HelloReply> SayHello(HelloRequest request, ServerCallContext context) { return Task.FromResult(new HelloReply { Message = "Hello " + request.Name }); } } }
客户端GRPC调用,代码如下
using Greet; using Grpc.Core; using System; namespace GrpcService1 { public class Program { public static void Main(string[] args) { var channel = new Channel("127.0.0.1", 95, ChannelCredentials.Insecure); var client = new Greeter.GreeterClient(channel); var result = client.SayHello(new HelloRequest { Name = "fanly" }); Console.WriteLine("grpc Client Call SayHello():" + result); Console.ReadKey(); } } }
2.支持WorkService后台托管守护程序
引擎支持WorkService后台服务,可以支持RPC远程调用开启,关闭,添加任务处理,代码如下:
添加接口代码如下:
[ServiceBundle("Background/{Service}")] public interface IWorkService : IServiceKey { Task<bool> AddWork(Message message); Task StartAsync(); Task StopAsync(); }
然后需要继承BackgroundServiceBehavior,而且服务的生命周期设置为ISingleInstance
public class WorkService : BackgroundServiceBehavior, IWorkService, ISingleInstance { private readonly ILogger<WorkService> _logger; private readonly Queue<Message> _queue = new Queue<Message>(); private readonly IServiceProxyProvider _serviceProxyProvider; private CancellationToken _token; public WorkService(ILogger<WorkService> logger, IServiceProxyProvider serviceProxyProvider) { _logger = logger; _serviceProxyProvider = serviceProxyProvider; } public Task<bool> AddWork(Message message) { _queue.Enqueue(message); return Task.FromResult(true); } protected override async Task ExecuteAsync(CancellationToken stoppingToken) { try { _token = stoppingToken; _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now); _queue.TryDequeue(out Message message); if (message != null) { var result = await _serviceProxyProvider.Invoke<object>(message.Parameters, message.RoutePath, message.ServiceKey); _logger.LogInformation("Invoke Service at: {time},Invoke result:{result}", DateTimeOffset.Now, result); } if (!_token.IsCancellationRequested) await Task.Delay(1000, stoppingToken); } catch (Exception ex){ _logger.LogError("WorkService execute error, message:{message} ,trace info:{trace} ", ex.Message, ex.StackTrace); } } public async Task StartAsync() { if (_token.IsCancellationRequested) { await base.StartAsync(_token); } } public async Task StopAsync() { if (!_token.IsCancellationRequested) { await base.StopAsync(_token); } } }
3.支持特性验证
支持接口特性验证,代码如下
[ServiceBundle("api/{Service}/{Method}")] //[ServiceBundle("api/{Service}")] //[ServiceBundle("api/{Service}/{Method}/test")] //[ServiceBundle("api/{Service}/{Method}/test",false)] public interface IUserService: IServiceKey { /// <summary> /// 获取用户姓名 /// </summary> /// <param name="id">用户编号</param> /// <returns></returns> [ServiceRoute("{id}")] Task<string> GetUserName([Validate] [Range(1, 10, ErrorMessage = "只能为1到10")] int id); /// <summary> /// 获取用户 /// </summary> /// <param name="user">用户模型</param> /// <returns></returns> [Command(Strategy = StrategyType.Injection, Injection = @"return new Surging.IModuleServices.Common.Models.UserModel { Name=""fanly"", Age=19 };", RequestCacheEnabled = true, InjectionNamespaces = new string[] { "Surging.IModuleServices.Common" })] [InterceptMethod(CachingMethod.Get, Key = "GetUser_id_{0}", CacheSectionType = SectionType.ddlCache, Mode = CacheTargetType.Redis, Time = 480)] [Validate] Task<UserModel> GetUser(UserModel user); }
支持模型特性验证,接口方法一定要添加 [Validate]特性,要不然不会进行验证,代码如下
[ProtoContract] public class UserModel { [ProtoMember(1)] [CacheKey(1)] public int UserId { get; set; } [ProtoMember(2)] public string Name { get; set; } [ProtoMember(3)] [Range(0, 150, ErrorMessage = "年龄只能在0到150岁之间")] public int Age { get; set; } [ProtoMember(4)] [Range(0, 1, ErrorMessage = "性别只能选男或女")] public Sex Sex { get; set; } }
