## Manipular tokens JWT { #handle-jwt-tokens }

Importe os módulos instalados.

Crie uma chave secreta aleatória que será usada para assinar os tokens JWT.

Para gerar uma chave secreta aleatória e segura, use o comando:

a Contributor if it was added to the Program by such Contributor itself or
anyone acting on such Contributor's behalf. Contributions do not include additions
to the Program which: (i) are separate modules of software distributed in
conjunction with the Program under their own license agreement, and (ii) are
not derivative works of the Program.

   "Contributor" means any person or entity that distributes the Program.

    /**
     * A helper method to determine the value to resume the build with {@code -rf} taking into account the edge case
     *   where multiple modules in the reactor have the same artifactId.
     * <p>
     * {@code -rf :artifactId} will pick up the first module which matches, but when multiple modules in the reactor
     *   have the same artifactId, effective failed module might be later in build reactor.

To create a distribution without running the tests, simply run the
following:

-----------------------------
./gradlew assemble
-----------------------------

To create a platform-specific build including the x-pack modules, use the
following depending on your operating system:

-----------------------------
./gradlew :distribution:archives:linux-tar:assemble
./gradlew :distribution:archives:darwin-tar:assemble

    void testEmptyModule() throws Exception {
        SimpleProblemCollector result = validate("empty-module.xml");

        assertViolations(result, 0, 1, 0);

        assertTrue(result.getErrors().get(0).contains("'modules.module[0]' has been specified without a path"));
    }

    @Test
    void testDuplicatePlugin() throws Exception {
        SimpleProblemCollector result = validateRaw("duplicate-plugin.xml");

### Избегайте конфликтов имён { #avoid-name-collisions }

Мы импортируем подмодуль `items` напрямую, вместо того чтобы импортировать только его переменную `router`.

```Python
from .routers import items, users
```

第二種是「絕對匯入」：

```Python
from app.routers import items, users
```

想了解更多關於 Python 套件與模組，請閱讀[官方的模組說明文件](https://docs.python.org/3/tutorial/modules.html)。

///

### 避免名稱衝突 { #avoid-name-collisions }

我們直接匯入子模組 `items`，而不是只匯入它的變數 `router`。

這是因為在子模組 `users` 中也有另一個名為 `router` 的變數。

如果我們像下面這樣一個接一個匯入：

```Python

    /**
     *
     *
     * Property {@code jcifs.resolveOrder} (string, default {@code LMHOSTS,DNS,WINS,BCAST})
     *
     * @return order and selection of resolver modules, see {@link ResolverType}
     */
    List<ResolverType> getResolveOrder();

    /**
     *
     * Property {@code jcifs.netbios.baddr} (string, default {@code 255.255.255.255})
     *
