}

    /**
     * Retrieves a list of URLs that are in the user's favorites from the provided URL list.
     * This method filters the input URL list to return only those URLs that the specified user
     * has marked as favorites.
     *
     * @param userCode the unique code identifying the user
     * @param urlList the list of URLs to check against the user's favorites

Например, у вас есть 4 API-эндпоинта (*операции пути*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

тогда вы можете добавить разные требования к правам для каждого из них только с помощью зависимостей и подзависимостей:

```mermaid
graph TB

current_user(["current_user"])

# Оголосіть змінну як str
# та отримайте підтримку редактора всередині функції
def main(user_id: str):
    return user_id


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

Далі це можна використовувати так:

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

second_user_data = {
    "id": 4,
    "name": "Mary",

這是怎麼運作的？來看一下。🤓

### 型別註解與工具支援 { #type-annotations-and-tooling }

先看看編輯器、mypy 與其他工具會怎麼看這件事。

`BaseUser` 有基礎欄位。然後 `UserIn` 繼承自 `BaseUser` 並新增 `password` 欄位，因此它會包含兩個模型的所有欄位。

我們把函式回傳型別註解為 `BaseUser`，但實際上回傳的是 `UserIn` 實例。

編輯器、mypy 與其他工具不會抱怨，因為就型別學而言，`UserIn` 是 `BaseUser` 的子類別，這代表當預期任何 `BaseUser` 時，`UserIn` 是一個有效的型別。

### FastAPI 的資料過濾 { #fastapi-data-filtering }

對 FastAPI 而言，它會查看回傳型別，並確保你回傳的內容只包含該型別中宣告的欄位。

        this.password = password;
    }

    /**
     * Username used to log in to the host
     */
    private String username;

    /**
     * Password associated with the login
     */
    private String password;

    /**
     * Get the user's password which is used when connecting to the repository.
     *
     * @return password of user
     */
    public String getPassword() {
        return password;

     */
    public void setHost(String host) {
        this.host = host;
    }

    /**
     * Get user's password used to log in to proxy server.
     *
     * @return user's password at proxy host
     */
    public String getPassword() {
        return password;
    }

    /**
     * Set the user's password for the proxy server.
     *
     * @param password password to use to log in to a proxy server
     */

Por ejemplo, digamos que tienes 4 endpoints de API (*path operations*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

entonces podrías agregar diferentes requisitos de permiso para cada uno de ellos solo con dependencias y sub-dependencias:

```mermaid
graph TB

  LINE_SEPARATOR("line.separator"),

  /** User's account name. */
  USER_NAME("user.name"),

  /** User's home directory. */
  USER_HOME("user.home"),

  /** User's current working directory. */
  USER_DIR("user.dir");

  private final String key;

  StandardSystemProperty(String key) {
    this.key = key;
  }

  /** Returns the key used to look up this system property. */

```Python
user_dict = user_in.model_dump()
UserInDB(**user_dict)
```

serait équivalent à :

```Python
UserInDB(**user_in.model_dump())
```

... parce que `user_in.model_dump()` est un `dict`, et nous demandons ensuite à Python de « déballer » ce `dict` en le passant à `UserInDB` précédé de `**`.

  LINE_SEPARATOR("line.separator"),

  /** User's account name. */
  USER_NAME("user.name"),

  /** User's home directory. */
  USER_HOME("user.home"),

  /** User's current working directory. */
  USER_DIR("user.dir");

  private final String key;

  StandardSystemProperty(String key) {
    this.key = key;
  }

  /** Returns the key used to look up this system property. */
