### 使用表单数据

/// tip | "提示"

`OAuth2PasswordRequestForm` 类依赖项的实例没有以空格分隔的长字符串属性 `scope`，但它支持 `scopes` 属性，由已发送的 scope 字符串列表组成。

本例没有使用 `scopes`，但开发者也可以根据需要使用该属性。

///

现在，即可使用表单字段 `username`，从（伪）数据库中获取用户数据。

如果不存在指定用户，则返回错误消息，提示**用户名或密码错误**。

本例使用 `HTTPException` 异常显示此错误：

```Python hl_lines="3  77-79"

                    props.remove(key + ERROR_KEY_SUFFIX);
                }

                getLogger().debug("Writing resolution-state to: " + touchfile);
                channel.truncate(0);
                props.store(Channels.newOutputStream(channel), "Last modified on: " + new Date());

                lock.release();
                lock = null;

                channel.close();
                channel = null;

            --set global.istioNamespace=istio-master
```

### Gateways

A cluster may use multiple Gateways, each with a different load balancer IP, domains and certificates.

Since the domain certificates are stored in the gateway namespace, it is recommended to keep each
gateway in a dedicated namespace and restrict access.

For large-scale gateways it is optionally possible to use a dedicated pilot in the gateway namespace.
