# Tutoriel - Guide utilisateur { #tutorial-user-guide }

Ce tutoriel vous montre comment utiliser **FastAPI** avec la plupart de ses fonctionnalités, étape par étape.

Chaque section s'appuie progressivement sur les précédentes, mais elle est structurée de manière à séparer les sujets, afin que vous puissiez aller directement à l'un d'entre eux pour répondre à vos besoins spécifiques d'API.

    return user_id


# 一个 Pydantic 模型
class User(BaseModel):
    id: int
    name: str
    joined: date
```

可以像这样来使用：

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

from fastapi.security import HTTPBasic, HTTPBasicCredentials

app = FastAPI()

security = HTTPBasic()


@app.get("/users/me")

    // Test with different from names
    @Test
    public void test_differentFromNames() {
        String[] fromNames = { "Administrator", "Support Team", "No Reply", "Test User" };

        for (String name : fromNames) {
            ComponentUtil.setFessConfig(new FessConfig.SimpleImpl() {
                private static final long serialVersionUID = 1L;

                @Override

    val httpUrl =
      HttpUrl
        .Builder()
        .scheme("http")
        .username("user")
        .host("host")
        .build()
    assertThat(httpUrl.toString()).isEqualTo("http://user@host/")
    assertThat(httpUrl.toUri().toString()).isEqualTo("http://user@host/")
  }

  @Test
  fun toUriUsernameSpecialCharacters() {
    val url =
      HttpUrl
        .Builder()

    return user_id


# Un modelo de Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Que luego puede ser usado como:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```
