surging English
surging 是一个分布式微服务框架,提供高性能RPC远程服务调用,采用Zookeeper、Consul作为surging服务的注册中心,集成了哈希,随机,轮询作为负载均衡的算法,RPC集成采用的是netty框架,采用异步传输。
启动配置:
var host = new ServiceHostBuilder()
.RegisterServices(builder =>
{
builder.AddMicroService(option =>
{
option.AddServiceRuntime();//
// option.UseZooKeeperManager(new ConfigInfo("127.0.0.1:2181")); //使用Zookeeper管理
option.UseConsulManager(new ConfigInfo("127.0.0.1:8500"));//使用Consul管理
option.UseDotNettyTransport();//使用Netty传输
option.UseRabbitMQTransport();//使用rabbitmq 传输
option.AddRabbitMQAdapt();//基于rabbitmq的消费的服务适配
// option.UseProtoBufferCodec();//基于protobuf序列化
option.UseMessagePackCodec();//基于MessagePack序列化
builder.Register(p => new CPlatformContainer(ServiceLocator.Current));//初始化注入容器
});
})
.SubscribeAt() //消息订阅
.UseServer("127.0.0.1", 98)
//.UseServer("127.0.0.1", 98,“true”) //自动生成Token
//.UseServer("127.0.0.1", 98,“123456789”) //固定密码Token
.UseStartup<Startup>()
.Build();
using (host.Run())
{
Console.WriteLine($"服务端启动成功,{DateTime.Now}。");
}
服务路由访问配置:
[ServiceBundle("api/{Service}")]
JWT验证,接口方法添加以下特性:
[Authorization(AuthType = AuthorizationType.JWT)];
AppSecret验证,接口方法添加以下特性:
[Authorization(AuthType = AuthorizationType.AppSecret)];
订阅功能:
ServiceLocator.GetService< ISubscriptionAdapt >().SubscribeAt();
增加服务容错、服务容错降级、服务强制降级
- 增加容错策略Injection,脚本注入:
[Command(Strategy= StrategyType.Injection ,Injection = @"return null;")]
[Command(Strategy= StrategyType.Injection ,Injection = @"return
Task.FromResult(new Surging.IModuleServices.Common.Models.UserModel
{
Name=""fanly"",
Age=18
});",InjectionNamespaces =new string[] { "Surging.IModuleServices.Common"})]
- 增加容错策略Injection,本地模块注入:
[Command(Strategy= StrategyType.Injection ,Injection = @"return true;")]
增加缓存降级,怎么使用?
在业务接口方法上添加如下特性
[Command(Strategy= StrategyType.Failover,FailoverCluster =3,RequestCacheEnabled =true)] //RequestCacheEnabled =true 就是启用缓存
怎么拦截获取缓存
在业务接口方法上添加如下特性
[InterceptMethod(CachingMethod.Get, Key = "GetUser_id_{0}", Mode = CacheTargetType.Redis, Time = 480)]
怎么拦截删除缓存
在业务接口方法上添加如下特性
[InterceptMethod(CachingMethod.Remove, "GetUser_id_{0}", "GetUserName_name_{0}", Mode = CacheTargetType.Redis)]
怎么添加缓存KEY
在业务模型属性上添加,如下特性,可以支持多个
[CacheKey(1)]
配置拦截器
.AddClientIntercepted(typeof(CacheProviderInterceptor))
IDE:Visual Studio 2017 15.3 Preview ,vscode
