## zh-CN
通过 `message.useMessage` 创建支持读取 context 的 `contextHolder`
## en-US
Use `message.useMessage` to get `contextHolder` with context accessible issue.
```jsx
import { message, Button } from 'antd';
const Context = React.createContext({ name: 'Default' });
function Demo() {
const [messageApi, contextHolder] = message.useMessage();
const info = () => {
messageApi.open({
type: 'info',
content: <Context.Consumer>{({ name }) => `Hello, ${name}!`}</Context.Consumer>,
duration: 1,
});
};
return (
<Context.Provider value={{ name: 'Ant Design' }}>
{contextHolder}
<Button type="primary" onClick={info}>
Display normal message
</Button>
</Context.Provider>
);
}
export default Demo;
```
