servicestack - 使用 ServiceStack 自定义服务挂钩

Question

我正在尝试实现自定义服务挂钩，这就是我到目前为止所做的......

全球.asax

public override IServiceRunner<TRequest> CreateServiceRunner<TRequest>(ActionContext actionContext)
{           
    return new MyServiceRunner<TRequest>(this, actionContext);
}

MyServiceRunner.cs

public class MyServiceRunner<T> : ServiceRunner<T> {
    public override void OnBeforeExecute(IRequestContext requestContext, TRequest request) {
      // Called just before any Action is executed
    }

    public override object OnAfterExecute(IRequestContext requestContext, object response) {
      // Called just after any Action is executed, you can modify the response returned here as well
    }

    public override object HandleException(IRequestContext requestContext, TRequest request, Exception ex) {
      // Called whenever an exception is thrown in your Services Action
    }
}

在 global.asax 中，返回语句显示错误“构造函数 MyServiceRunner 有 0 个参数，但使用 2 个参数调用”。

有人可以帮助我吗...如果可以的话，我绝对需要使用 actionContext。

你需要一个构造函数，它应该是：

public class MyServiceRunner<T> : ServiceRunner<T> 
{
  public MyServiceRunner(IAppHost appHost, ActionContext actionContext) 
      : base(appHost, actionContext) {}

  public override void OnBeforeExecute(IRequestContext requestContext, 
     TRequest request) {
    // Called just before any Action is executed
  }

  public override object OnAfterExecute(IRequestContext requestContext, 
     object response) {
      // Called just after any Action is executed, you can modify the response
  }

  public override object HandleException(IRequestContext requestContext, 
      TRequest request, Exception ex) {
    // Called whenever an exception is thrown in your Services Action
  }
}
