在服务启动注册的时候，会进行except，因没有判断是否是同一服务地址，所以把except得到的结果删除，导致多个服务部署出现问题。

builder.Services.Register(provider =>new ServiceProxyFactory(
                 provider.Resolve<IRemoteInvokeService>(),
                 provider.Resolve<ITypeConvertibleService>(),
                 provider.Resolve<IServiceProvider>(),
                 builder.GetInterfaceService()
                 )).As<IServiceProxyFactory>().SingleInstance();

new ServiceProxyFactory应该与UseProxy的作用重复了

1、服务publish在本地电脑，网关可以调用服务，且能够正确返回应有的数据，如下图：

2、部署到开发环境，环境如下：

apigateway:

authservice：

orgservice:

以上服务都已正常启动:

总结：问题暂时不知道出现在哪里？服务都已正常的注册等

您这个项目我感觉非常有意思，我调试了环境，把项目跑起来了，但是缺少c:\routes.txt能否给个例子，非常感谢。

作者你好，
这是我写的一个SurgingDemo，还烦请问使用姿势是否正确 -_-...
如果用的不对的地方，还请指正，谢谢
本示例git surging 到本地，再另外新建的Demo，通过引用Surging项目到Demo来实现，这样加深学习。
ORM使用的是Dapper

群主，交流群解散了吗？怎么突然找不到了。

我讲demo中的接口

    [Command(Strategy = StrategyType.Injection, Injection = @"return

new Surging.IModuleServices.Common.Models.UserModel
{
Name=""fanly"",
Age=19
};", InjectionNamespaces = new string[] { "Surging.IModuleServices.Common" }, RequestCacheEnabled = true)]
[Service(Date = "2017-8-11", Director = "fanly", Name = "获取用户")]
[InterceptMethod(CachingMethod.Get, Key = "GetUser_id_0", CacheSectionType = SectionType.ddlCache, Mode = CacheTargetType.Redis, Time = 480)]
Task GetUser(UserModel user);

属性RequestCacheEnabled 修改为true 想进入InterceptMethod 查看操作缓存的过程，结果报错，麻烦给看看是怎么回事，配置哪里有问题么？

源码是proxyType.GetTypeInfo().GetConstructors().First().Invoke 来获取代理对象

@fanliang11 我独立创建领域及控制台执行，并启动服务完成了服务的注册，对接口进行调用也OK；98端口为源项目服务，99是我自己实现的一个demo；现想把自己实现的服务寄宿在98端口对应的服务上，一直没有成功；我进行两种尝试
1.98服务启动后 将领域dll直接扔到服务目录一直无法发现服务；
2.98端口服务停掉，先放自现实的dll再启动，会报异常，无法加载所给的dll;

在服务运行一段时间后，会出现连接rabbitmq的异常，不知是什么原因。

写法是一样的 引用也是一样的，需要在哪里重新注册吗

场景：有2个一样的服务，加入网关，对外以http方式提供给app调用，给app调用的这个url是怎么组合的呢？网关host+model id+方法名吗？

这个项目没有单元测试？性能怎样？

您好，前几天下载下来学习，想在本地运行一下，出现 由于目标计算机积极拒绝，无法连接
本地开发环境的是是vs2017 ，求指导

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？

开发状态下，编译和运行没有任何问题，但是发布后，无法运行。
怀疑是没有排除多余的类库

我直接在客户端引用了领域服务的实现，但还是调用了代理对象

直接扔DLL就能注册，无需重新启动服务

“ServiceAggregation”：[
{
           "RoutePath": "api/user/getuser",
           "ServiceKey": "User",
          "Params":{"UserId":1},
           "Key":"Users"
},
{
           "RoutePath": "api/user/getuser",
           "ServiceKey": "User",
          "Params":{"UserId":1},
           "Key":"Roles"
}]
}

result return:

{"User":{"UserId": 1,"Name":"Fanly","Age":18},"Roles":{"RoleName": "Admin"}}

客户端创建代理的时候，怎么知道连接的服务端地址的？

问题描述：
方法定义：public Task GetUserLevelModel(string userid)

此时如果http post的请求中，没有传递参数，目前机制是直接返回结果：{"Entity":null,"IsSucceed":true,"Message":"","StatusCode":200}
resp结果中没有参数不正确的提示；

且：此时用户的代码压根没执行，因此用户程序中参数为空的检查是不执行的。

原因分析：经过断点跟踪，
在 public async Task<ServiceResult> Path(string path, [FromQuery]string serviceKey, [FromBody]Dictionary<string, object> model) 的model参数为null或者参数的key不在model中，在发起rpc调用时TransportClient类 SendAsync方法，会抛异常，api网关直接将返回如上结果。

结论：此处的判断逻辑或者说错误提示应该更加明确，在参数不齐全的情况下，异常后的排查成本会很高。

我在使用api网关时，遇到几点小问题

1. ModuleName 是不是取Service前的Name；比如UserAppService, ModuleName 是UserApp , 取User 不行

2. 使用api网关能否指定http Method, GET/ POST ; 貌似现在只能是 POST JSON

在Postman上测试没问题：

通过AJAX调用报错：Unsupported Media Type

AJAX如下：

配置大于多少字符长度，开启数据压缩功能，以降低网络传输带来的损耗

1. 运行网关程序

可以把红框的（服务 | | 领域接口）删除，只部署运行的网关

2. 新建服务项目

2.1 需要引用的服务创建

2.2 无需引用的服务创建

这里只是个人的简单理解和使用，继续研究和使用作者代码，感谢作者的支持

代码生成不支持返回自定义类型数组，暂时替代方案可以使用ICollection<>代替

我用这种方式远程调用接口，同时已经将远程接口引用到项目中

this.GetService<IProductService>().GetProduct(1);

远程服务接口声明

[Service(Date ="20180106",Director ="",Name ="获取产品数据")]
  Task<string> GetProduct(int id);

请帮忙分析一下原因，看看我的用法有问题吗，顺便能给出一个服务间调用的实例demo么，这个比较急，谢谢了！

上图在服务中调用另一个微服务时，报找不到实体类，下图是可以的

serviceProxyProvider.Invoke(model, path, serviceKey);
我写了一个测试 在service.client
public static void Test(IServiceProxyProvider serviceProxyProvider)
{
Dictionary<string, object> model = new Dictionary<string, object>();
model.Add("UserId", "1");
string path = "api/user/getuser";
string serviceKey = "User";

        var userProxy = serviceProxyProvider.Invoke<object>(model, path, serviceKey);
        var s = userProxy.Result;
    }

想通过api 方式调用服务
服务端和客户端启动后

user返回的信息

返回的是自定义属性当中的？

rabbitMQ的密码配置项读取了用户名的配置项

    public Task<string> GetUserName(int id)
    {
        Console.WriteLine("被调用");

        StartRequest1();

        return Task.FromResult($"id:{id} is name fanly.");
    }


    private static void StartRequest1()
    {

        var service = ServiceLocator.GetService<IServiceProxyFactory>();
        var userProxy = service.CreateProxy<IUser2Service>();
        var ss = userProxy.GetUserName(123);
        Console.WriteLine(ss);
