# Recipes

We've written some recipes that demonstrate how to solve common problems with OkHttp. Read through them to learn about how everything works together. Cut-and-paste these examples freely; that's what they're for.

이게 다입니다.

**단 두 줄입니다**.

그리고, 이 함수는 여러분의 모든 *경로 작동 함수*가 가지고 있는 것과 같은 형태와 구조를 가지고 있습니다.

여러분은 이를 "데코레이터"가 없는 (`@app.get("/some-path")`가 없는) *경로 작동 함수*라고 생각할 수 있습니다.

그리고 여러분이 원하는 무엇이든 반환할 수 있습니다.

이 경우, 이 의존성은 다음과 같은 경우를 기대합니다:

* 선택적인 쿼리 매개변수 `q`, `str`을 자료형으로 가집니다.
* 선택적인 쿼리 매개변수 `skip`, `int`를 자료형으로 가지며 기본 값은 `0`입니다.
