两个服务之间该怎么调用呢？

[daofenglg]

var result = this.GetService().GetMembers(10).Result; 用这个调用本服务是可以的，但是如何调用其他服务的接口呢？
例如我有两个服务一个订单服务，一个库存服务，我要在订单的服务中调用库存的服务,订单服务是不是需要引用订单服务中定义的接口库？

[fanliang11]

this.GetService<IUser2Service>().GetUserName(123);

如果是远程调用就引用接口，如果是本地调用就要引用模块的领域服务和接口了。订单服务还需要添加
option.AddRelateService();//添加支持服务代理 ，具体可以看看 #37

[daofenglg]

代码实现：
` var serviceProxyFactory=this.GetService();

        var userProxy = serviceProxyFactory.CreateProxy<IFactService>();
         Task task= userProxy.GetFacts(10);

`
接口已经引用到项目，在调用时引发了异常：
System.InvalidCastException:“Unable to cast object of type 'Microsoft.CodeAnalysis.CSharp.Syntax.QualifiedNameSyntax' to type 'Microsoft.CodeAnalysis.CSharp.Syntax.GenericNameSyntax'.”

[fanliang11]

this.GetService<IUser2Service>().GetUserName(123);

这个方法就可以了，不需要创建代理，会自动判断是否远程调用

[daofenglg]

1. var result = this.GetService().GetMembers(10).Result; 是本地的接口是可以调用的
2. this.GetService().GetFacts(10);这个是需要远程调用的接口，还是报上面那个异常。
   以下是远程调用接口的实现：

[ServiceBundle("api/{Service}")]
public interface IFactService:IServiceKey
{
[Command(ExecutionTimeoutInMilliseconds = 1000*5, RequestCacheEnabled = false)]
[Service(Date = "201-01-03", Director = "ligang", Name = "获取品牌数据")]
Task GetFacts(int count);

    [Service(Date = "2018-01-03", Director = "ligang", Name = "测试方法")]
    string GetTst();
}

option.AddRelateService();添加了吗

[daofenglg]

class Program
{
    static void Main(string[] args)
    {
        Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
        var host = new ServiceHostBuilder()
          .RegisterServices(builder =>
          {
              builder.AddMicroService(option =>
              {
                  option.AddServiceRuntime();
                  option.AddRelateService(); ;//添加支持服务代理
                  //option.UseZooKeeperManager(new ConfigInfo("127.0.0.1:2181"));
                  option.UseConsulManager(new ConfigInfo("192.168.1.199:8500"));
                  option.UseDotNettyTransport();
                  option.UseRabbitMQTransport();
                  option.AddRabbitMQAdapt();
                  //option.UseProtoBufferCodec();
                  option.UseMessagePackCodec();
                  builder.Register(p => new CPlatformContainer(ServiceLocator.Current));
              });
          })
          .SubscribeAt()
          .UseLog4net("Configs/log4net.config")
          //.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
          .UseServer(options =>
          {
              options.Ip = "127.0.0.1";
              options.Port = 11011;
              options.Token = "True";
              options.ExecutionTimeoutInMilliseconds = 30000;
              options.MaxConcurrentRequests = 200;
          })
          .UseStartup<Startup>()
          .Build();
        using (host.Run())
        {
            Console.WriteLine($"服务端启动成功，{DateTime.Now}。");
        }
    }
}

错误信息贴出来

[daofenglg]

[fanliang11]

不支持直接返回string,请用Task

[daofenglg]

刚才那个问题解决了，我接口的返回都改成了task，但是又有一个新的问题

下面是接口的声明
[ServiceBundle("api/{Service}")]
public interface IFactService:IServiceKey
{
[Command(ExecutionTimeoutInMilliseconds = 1000 * 5, RequestCacheEnabled = false)]
[Service(Date = "201-01-03", Director = "ligang", Name = "获取品牌数据")]
Task<List> GetFacts(int count);

    //[Service(Date = "2018-01-03", Director = "ligang", Name = "测试方法")]
    //Task<List<string>> GetTst();
}

下面是通过引用查看看到的临时文件内容
[global::Surging.Core.CPlatform.Runtime.Server.Implementation.ServiceDiscovery.Attributes.ServiceBundleAttribute("api/{Service}")]
public interface IFactService : global::Surging.Core.CPlatform.Ioc.IServiceKey
{
[global::Surging.Core.CPlatform.Support.Attributes.CommandAttribute(ExecutionTimeoutInMilliseconds = 5000, RequestCacheEnabled = false)]
[global::Surging.Core.CPlatform.Runtime.Server.Implementation.ServiceDiscovery.Attributes.ServiceAttribute(Date = "201-01-03", Director = "ligang", Name = "获取品牌数据")]
System.Threading.Tasks.Task<System.Collections.Generic.List<Api.Models.TblFactoryModel>> GetFacts(int count);
}
