### Krok 3: wykonaj *operację na ścieżce*

#### Ścieżka

"Ścieżka" tutaj odnosi się do ostatniej części adresu URL, zaczynając od pierwszego `/`.

Więc, w adresie URL takim jak:

```
https://example.com/items/foo
```

...ścieżką będzie:

```
/items/foo
```

/// info

"Ścieżka" jest zazwyczaj nazywana "path", "endpoint" lub "route'.

El código real del callback dependerá mucho de tu propia aplicación API.

Y probablemente variará mucho de una aplicación a otra.

Podría ser solo una o dos líneas de código, como:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

 * <p><b>Warning:</b> The methods of {@code ForwardingMap} forward <i>indiscriminately</i> to the
 * methods of the delegate. For example, overriding {@link #put} alone <i>will not</i> change the
 * behavior of {@link #putAll}, which can lead to unexpected behavior. In this case, you should

     * might not run some of its listeners. The likely result is that the app will hang. (And of
     * course stack overflows are bad news in general. For example, we may have overflowed in the
     * middle of defining a class. If so, that class will never be loadable in this process.) The
     * best we can do (since logging may overflow the stack) is to let the error propagate. Because

### Получение собственных пользовательских данных

Теперь, используя операцию `GET` с путем `/users/me`, вы получите данные пользователя, например:

```JSON
{
  "username": "johndoe",
  "email": "johndoe@example.com",
  "full_name": "John Doe",
  "disabled": false,
  "hashed_password": "fakehashedsecret"
}
```

    assertThat(CertificateAdapters.generalName.fromDer(bytes))
      .isEqualTo(generalNameDnsName to "example.com")
    assertThat(CertificateAdapters.generalName.toDer(generalNameDnsName to "example.com"))
      .isEqualTo(bytes)
  }

/**
 * An implementation of {@code ListMultimap} that supports deterministic iteration order for both
 * keys and values. The iteration order is preserved across non-distinct key values. For example,
 * for the following multimap definition:
 *
 * {@snippet :
 * Multimap<K, V> multimap = LinkedListMultimap.create();
 * multimap.put(key1, foo);

 * }

    throw new NullPointerException("Both parameters are null");
  }

  /**

   *
   * <p>This is helpful for implementing {@link Object#toString()}. Specification by example:
   *
   * {@snippet :

   * MoreObjects.toStringHelper(this)
   *     .toString();
   *
   * // Returns "ClassName{x=1}"
   * MoreObjects.toStringHelper(this)

     * most common. This is the state information that would be retrieved from
     * WINS for example. Natrually it is not practical for every NbtAddress
     * to be populated will all state requiring a Node Status on every host
     * encountered. The below methods allow state to be populated when requested

### 3 단계: *경로 작동* 생성

#### 경로

여기서 "경로"는 첫 번째 `/`부터 시작하는 URL의 뒷부분을 의미합니다.

그러므로 아래와 같은 URL에서:

```
https://example.com/items/foo
```

...경로는 다음과 같습니다:

```
/items/foo
```

/// info | 정보

"경로"는 일반적으로 "엔드포인트" 또는 "라우트"라고도 불립니다.

///

API를 설계할 때 "경로"는 "관심사"와 "리소스"를 분리하기 위한 주요한 방법입니다.
