Callback
The behavior of SimpleW can be overridden using a sort of callback.
OnBeforeMethod
The Controller class contains an abstract method OnBeforeMethod() which is called before any method execution.
csharp
using System;
using System.Net;
using SimpleW;
namespace Sample {
class Program {
static void Main() {
var server = new SimpleWServer(IPAddress.Any, 2015);
server.AddDynamicContent("/api");
server.Start();
Console.WriteLine("server started at http://localhost:2015/");
Console.ReadKey();
}
}
[Route("/test")]
public class TestController : Controller {
// Router will call this methods before another one
public override void OnBeforeMethod() {
Console.WriteLine("OnBeforeMethod()");
}
[Route("GET", "/index")]
public object Index() {
return "test index page";
}
[Route("POST", "/create")]
public object Create() {
return "test create success";
}
}
}Subclass
A better approach for adding some logic code to all your controllers is by extending the Controller class.
Example using a BaseController class that contains common code to all controllers.
csharp
using System;
using System.Net;
using SimpleW;
namespace Sample {
class Program {
static void Main() {
var server = new SimpleWServer(IPAddress.Any, 2015);
server.AddDynamicContent("/api");
server.Start();
Console.WriteLine("server started at http://localhost:2015/");
Console.ReadKey();
}
}
class BaseController : Controller {
// example of property used in subclass
protected Repository _repo = new();
}
[Route("/user")]
class UserController : BaseController {
[Route("GET", "/index")]
public object Index() {
var users = _repo.GetAll<User>();
return users;
}
}
[Route("/department")]
class DepartmentController : BaseController {
[Route("GET", "/index")]
public object Index() {
var departments = _repo.GetAll<Department>();
return departments;
}
}
}The subclass can contains route's method too. To avoid this subclass being parsed by the router, it must be excluded. Use the AddDynamicContent() exclude parameter.
csharp
using System;
using System.Net;
using SimpleW;
namespace Sample {
class Program {
static void Main() {
var server = new SimpleWServer(IPAddress.Any, 2015);
// exclude BaseController as a regular Controller
server.AddDynamicContent("/api", new Type[] { typeof(BaseController) });
server.Start();
Console.WriteLine("server started at http://localhost:2015/");
Console.ReadKey();
}
}
class BaseController : Controller {
[Route("GET", "/conf")]
public object Conf() {
return "conf";
}
}
[Route("/user")]
class UserController : BaseController {
}
[Route("/department")]
class DepartmentController : BaseController {
}
}Note : the method BaseController.Conf() with its Route attribute is shared across all controllers. It can be access through :
