## zh-CN

通过 `notification.useNotification` 创建支持读取 context 的 `contextHolder`。请注意，我们推荐通过顶层注册的方式代替 `message` 静态方法，因为静态方法无法消费上下文，因而 ConfigProvider 的数据也不会生效。

## en-US

Use `notification.useNotification` to get `contextHolder` with context accessible issue. Please note that, we recommend to use top level registration instead of `notification` static method, because static method cannot consume context, and ConfigProvider data will not work.

```jsx
import { Button, notification, Divider, Space } from 'antd';
import {
  RadiusUpleftOutlined,
  RadiusUprightOutlined,
  RadiusBottomleftOutlined,
  RadiusBottomrightOutlined,
} from '@ant-design/icons';

const Context = React.createContext({ name: 'Default' });

const Demo = () => {
  const [api, contextHolder] = notification.useNotification();

  const openNotification = placement => {
    api.info({
      message: `Notification ${placement}`,
      description: <Context.Consumer>{({ name }) => `Hello, ${name}!`}</Context.Consumer>,
      placement,
    });
  };

  return (
    <Context.Provider value={{ name: 'Ant Design' }}>
      {contextHolder}
      <Space>
        <Button type="primary" onClick={() => openNotification('topLeft')}>
          <RadiusUpleftOutlined />
          topLeft
        </Button>
        <Button type="primary" onClick={() => openNotification('topRight')}>
          <RadiusUprightOutlined />
          topRight
        </Button>
      </Space>
      <Divider />
      <Space>
        <Button type="primary" onClick={() => openNotification('bottomLeft')}>
          <RadiusBottomleftOutlined />
          bottomLeft
        </Button>
        <Button type="primary" onClick={() => openNotification('bottomRight')}>
          <RadiusBottomrightOutlined />
          bottomRight
        </Button>
      </Space>
    </Context.Provider>
  );
};

export default Demo;
```
