.NET - Api.Route.All()

Register a single handler for all HTTP Methods (GET, POST, PUT, DELETE, PATCH) on the route.

using Nitric.Sdk;

var route = Nitric.Api("main").Route("/customers");

route.All(context => {
    // Construct a response for all incoming HTTP requests
    var responseBody = new Dictionary<string, string>();
    context.Res.Json(responseBody);

    return context;
});

Nitric.Run();

Parameters

  • Name
    ...middleware
    Required
    Required
    Type
    Middleware<HttpContext> or Func<HttpContext, HttpContext>
    Description

    One or more middleware functions to use as the handler for HTTP requests. Handlers can be sync or async.

Notes

When using the All() method to register a single function as the handler for all HTTP methods, none of the other methods should be defined on that route.

using Nitric.Sdk;

var route = Nitric.Api("main").Route("/customers");

route.All(context => {
  /* handle all requests */
});

// Don't call `Get()`, `Post()`, etc., they're already handled by `all()`
route.Get(context => {
  // This handler won't work
})

Nitric.Run();

Examples

Register a method handler function

using Nitric.Sdk;

var route = Nitric.Api("main").Route("/customers");

route.All(context => {
    // Construct a response for all incoming HTTP requests
    var responseBody = new Dictionary<string, string>();
    context.Res.Json(responseBody);

    return context;
});

Nitric.Run();

Chain functions as a single method handler

When multiple functions are provided they will be called as a chain. If one succeeds, it will move on to the next. This allows middleware to be composed into more complex handlers.

var route = Nitric.Api("main").Route("/customers");

route.All((context, next) => {
    var user = context.Req.PathParams["userId"];

    // Validate the user identity
    if (user != "1234")
    {
        context.Res.Text($"User {user} is unauthorised");
        context.Res.Status = 403;

        // Return prematurely to end the middleware chain.
        return context;
    }

    // Call next to continue the middleware chain.
    return next(context);
  }, (context, next) => {
    var user = context.Req.PathParams["userId"];

    context.Res.Text($"Handling {user}");

    return next(context);
  }
);

Nitric.Run();

Access the request body

For methods that include a request body, such as POST and PUT, you can access the body from the ctx.req object.

using Nitric.Sdk;

var api = Nitric.Api("main").Route("/customers");

route.All(context => {
  var body = context.Req.Json<Dictionary<string, string>>();
  // parse, validate and store the request payload...
});

Nitric.Run();
