Where the spec is ambiguous, OkHttp follows modern user agents such as popular Browsers or common HTTP Libraries.

OkHttp is principled and avoids being overly configurable, especially when such configuration is
to workaround a buggy server, test invalid scenarios or that contradict the relevant RFC.

## Tạo một Dự án

Đầu tiên, tạo một thư mục cho dự án của bạn.

Cách tôi thường làm là tạo một thư mục có tên `code` trong thư mục `home/user`.

Và trong thư mục đó, tôi tạo một thư mục cho mỗi dự án.

<div class="termy">

```console
// Đi đến thư mục home
$ cd
// Tạo một thư mục cho tất cả các dự án của bạn
$ mkdir code
// Vào thư mục code
$ cd code
// Tạo một thư mục cho dự án này
$ mkdir awesome-project

# Pfad-Parameter und Validierung von Zahlen

So wie Sie mit `Query` für Query-Parameter zusätzliche Validierungen und Metadaten hinzufügen können, können Sie das mittels `Path` auch für Pfad-Parameter tun.

## `Path` importieren

Importieren Sie zuerst `Path` von `fastapi`, und importieren Sie `Annotated`.
