Dart - api.route.get()

Register a handler for HTTP GET requests to the route.

import 'package:nitric_sdk/nitric.dart';
final customersRoute = Nitric.api("public").route("/customers");
customersRoute.get((ctx) async {
// construct response for the GET: /customers request...
final responseBody = {};
ctx.res.json(responseBody);
return ctx;
});

Parameters

    handler
    Required
    Required
    Type
    HttpHandler
    Description

    The middleware service to use as the handler for HTTP requests.

Examples

Register a handler for GET requests

import 'package:nitric_sdk/nitric.dart';
final customersRoute = Nitric.api("public").route("/customers");
customersRoute.get((ctx) async {
// construct response for the GET: /customers request...
final responseBody = {};
ctx.res.json(responseBody);
return ctx;
});

Chain services as a single method handler

When multiple services 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. You can call the next middleware in the chain using ctx.next(). If a middleware in the chain does not call .next and instead returns the base context, the call chain will end.

import 'package:nitric_sdk/nitric.dart';
Future<HttpContext> validate(HttpContext ctx) async {
if (!ctx.req.headers.containsKey("Content-Type")) {
ctx.res.status = 400;
ctx.res.body = "header Content-Type is required";
// End the middleware chain by not calling `ctx.next()`.
return ctx;
}
return ctx.next();
}
Future<HttpContext> getCustomer(HttpContext ctx) async {
// handle the GET request...
return ctx.next();
}
// The validate middleware will run before all handlers that are created using this route
final customersRoute = Nitric.api("public").route("/customers", middlewares: [validate]);
// The validate middleware will run before the getCustomer handler
customersRoute.get(getCustomer);
