`Header` has a little extra functionality on top of what `Path`, `Query` and `Cookie` provide.

Most of the standard headers are separated by a "hyphen" character, also known as the "minus symbol" (`-`).

But a variable like `user-agent` is invalid in Python.

So, by default, `Header` will convert the parameter names characters from underscore (`_`) to hyphen (`-`) to extract and document the headers.

            tempDir.delete();
            tempDir.mkdirs();

            // robots.txt
            StringBuilder buf = new StringBuilder();
            buf.append("User-agent: *").append('\n');
            buf.append("Disallow: /admin/").append('\n');
            buf.append("Disallow: /websvn/").append('\n');
            final File robotTxtFile = new File(tempDir, "robots.txt");

## 자동 변환

`Header`는 `Path`, `Query` 그리고 `Cookie`가 제공하는 것 외에 기능이 조금 더 있습니다.

대부분의 표준 헤더는 "마이너스 기호" (`-`)라고도 하는 "하이픈" 문자로 구분됩니다.

그러나 파이썬에서 `user-agent`와 같은 형태의 변수는 유효하지 않습니다.

따라서 `Header`는 기본적으로 매개변수 이름을 언더스코어(`_`)에서 하이픈(`-`)으로 변환하여 헤더를 추출하고 기록합니다.

또한 HTTP 헤더는 대소문자를 구분하지 않으므로 "snake_case"로 알려진 표준 파이썬 스타일로 선언할 수 있습니다.

OkHttp may add headers that are absent from the original request, including `Content-Length`, `Transfer-Encoding`, `User-Agent`, `Host`, `Connection`, and `Content-Type`. It will add an `Accept-Encoding` header for transparent response compression unless the header is already present. If you’ve got cookies, OkHttp will add a `Cookie` header with them.
