Nest JS: how to define multiple endpoints in a single controller?-CodePudding

Is there a way to define multiple endpoints inside a single controller? It is described in the documentation: https://docs.nestjs.com/controllers#routing...

...Since we've declared a prefix for every route ( cats), and haven't added any path information in the decorator, Nest will map GET /cats requests to this handler. As mentioned, the path includes both the optional controller path prefix and any path string declared in the request method decorator. For example, a path prefix of customers combined with the decorator @Get('profile') would produce a route mapping for requests like GET /customers/profile

How do I define a controller with multiple endpoints?

I want:

/ /dogs /fish

and Im trying to achieve this with

@Controller()
export class AppController {
  constructor(private readonly appService: AppService) { }

  @Get()
  getHello(): string {
    return "<h1>AppController @Get (root URL) working</h1>";
  }

  @Get('dogs')
  getHello(): string {
    return "<h1>AppController @Get dogs working</h1>";
  }

  @Get('fish')
  getHello(): string {
    return "<h1>AppController @Get fish working</h1>";
  }
}

The problem with this is only the last @Get decorated function is accessible. i.e. whichever endpoint i shuffle to the end of this codeblock is the only one accessible through the browser address bar.

Because your implementation has functions with identical names that end up in the internal registry under the same key

CodePudding user response：

The function name is significant despite the fact the docs say it can be anything, it has to be unique. This works:

@Controller()
export class AppController {
  constructor(private readonly appService: AppService) { }

  @Get('fish')
  getFish(): string {
    return "<h1>AppController @Get fish working</h1>";
  }

  @Get('dogs')
  getDogs(): string {
    return "<h1>AppController @Get dogs working</h1>";
  }

  @Get()
  getHello(): string {
    return this.appService.getHello();
  }
}
