   默认不允许跨app访问，把注册的app改为一致即可
   
   sc的这约束我也不是很喜欢，不过接口不可轻易变更啊，所以一直就没有改
   
   在go chassis端，我做了规避，给用户更好的体验
   
   ```go
   // GetRegistratorScope returns the Scope of service registry
   func GetRegistratorScope() string {
   	if GlobalDefinition.Cse.Service.Registry.Registrator.Scope == "" {
   		GlobalDefinition.Cse.Service.Registry.Registrator.Scope = common.ScopeFull
   	}
   	return GlobalDefinition.Cse.Service.Registry.Scope
   }
   ```
   
   
   ```go
   	if config.GetRegistratorScope() == common.ScopeFull {
   		microservice.Metadata["allowCrossApp"] = common.TRUE
   		service.ServiceDescription.Properties["allowCrossApp"] = common.TRUE
   	} else {
   		service.ServiceDescription.Properties["allowCrossApp"] = common.FALSE
   	}
   ```
   
   可以看出go chassis处理时 默认不配置就可以允许跨app访问了。
   
   可否对我们的service center文档进行些完善说明@little-cui
