### Step 3: create a *path operation* { #step-3-create-a-path-operation }

#### Path { #path }

"Path" here refers to the last part of the URL starting from the first `/`.

So, in a URL like:

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

...the path would be:

```
/items/foo
```

/// info

A "path" is also commonly called an "endpoint" or a "route".

tls              (on|off)    set to 'on' to enable TLS
tls_skip_verify  (on|off)    trust server TLS without verification, defaults to "on" (verify)
client_tls_cert  (path)      path to client certificate for mTLS auth
client_tls_key   (path)      path to client key for mTLS auth
queue_dir        (path)      staging dir for undelivered messages e.g. '/home/events'
queue_limit      (number)    maximum limit for undelivered messages, defaults to '100000'

     * @param path The path to match.
     * @return The matching FtpAuthentication object, or null if no match is found.
     */
    public FtpAuthentication get(final String path) {
        if (path == null) {
            return null;
        }

        for (final FtpAuthentication auth : authenticationList) {
            if (auth.matches(path)) {
                return auth;

## `PATH` এনভায়রনমেন্ট ভেরিয়েবল

**`PATH`** নামে একটি **বিশেষ** এনভায়রনমেন্ট ভেরিয়েবল রয়েছে, যেটি প্রোগ্রাম রান করার জন্য অপারেটিং সিস্টেমস (লিনাক্স, ম্যাকওএস, উইন্ডোজ) দ্বারা ব্যবহৃত হয়।

## Variable de Entorno `PATH`

Hay una variable de entorno **especial** llamada **`PATH`** que es utilizada por los sistemas operativos (Linux, macOS, Windows) para encontrar programas a ejecutar.

El valor de la variable `PATH` es un string largo que consiste en directorios separados por dos puntos `:` en Linux y macOS, y por punto y coma `;` en Windows.

    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)

헤더 매개변수를 `Query`, `Path` 그리고 `Cookie` 매개변수들과 같은 방식으로 정의할 수 있습니다.

## `Header` 임포트

먼저 `Header`를 임포트합니다:

{* ../../docs_src/header_params/tutorial001.py hl[3] *}

## `Header` 매개변수 선언

`Path`, `Query` 그리고 `Cookie`를 사용한 동일한 구조를 이용하여 헤더 매개변수를 선언합니다.

첫 번째 값은 기본값이며, 추가 검증이나 어노테이션 매개변수 모두 전달할 수 있습니다:

{* ../../docs_src/header_params/tutorial001.py hl[9] *}
