NestJs @Query @body

뭔가를 원한다면 요청해야한다

@Post 리퀘스트의 body 부분을 가져오고 싶다고 하자

무비를 생성할때 body를 가져오고 싶을때

@Post()
create() {
    return "This will create a movie";
}

현재 상태에서 body도 가져오고 싶을때

{
"name": "Tenet",
"director": "kon"
}

—

@Post()
create(@Body() movieData) {
    console.log(movieData);
    return "This will create a movie";
}

@Body : movieData 데이터를 가져오기 위함

Patch 부
수정부

    @Patch('/:id')
    update(@Param('id') movieId: string, @Body() updateData) {
        // return `this will update a movie with the id: ${movieId}`;
        return {
            updatedMovie: movieId, 
          ...updateData,  
        };
    }
}

http://localhost:3000/movies/12

post맨으로 날릴 데이터

{
    "name": "Tenet",
    "director": "kon"
}

리턴값

{
    "updatedMovie": "12",
    "name": "Tenet",
    "director": "kon"
}

수정후 json을 돌려받았다

@Body() updateData
직접적으로 필요한 데이터는 요청해서 받아야한다

    @Get("search")
    search() {
        return `We are searching for a movie with a title:`;
    }

search를 통해 리퀘스트를 받도록 만들고 싶다

        @Get("search")
    search() {
        return `We are searching for a movie with a title:`;
        }
    
    @Get("/:id")
    getOne(@Param('id') id: string) {
        return `this will return one movie with the id: ${id}`;
    }

⭐️ Search 부분이 get 보다 밑에 있으면 NestJs는 search를 id로 판단

위치 이동 시킨 것

http://localhost:3000/movies/search?year=2000

    @Get('search')                                 //search
    search(@Query("year") searchingYear:string) {    //search?year=입력값
        return `We are searching for a movie made after:${searchingYear}`;
        }
   

뭔가를 요청하면 받아올 수 있다
Query parameters 랑 body decorators를 배웠다
