javascript - 如何从父组件获取intl.formatMessage？

Question

如何从父组件获取 intl.formatMessage ？我用injectIntl​​包装了父组件，并希望将intl.formatMessage发送到子组件。有人可以帮我吗？谢谢!

父组件

import Car from "./test3";
import { injectIntl } from "react-intl";

class Intl extends React.Component {
  render() {
    return (
      <div>
        <h1>Who lives in my garage?</h1>
        <Car brand="Ford" />
      </div>
    );
  }
}

export default injectIntl(Intl);

子组件

import { FormattedMessage} from "react-intl";

class Car extends React.Component {
  yearsTranslation = () =>
    this.props.intl.formatMessage({ id: "search.filter.maturity.years" });
  render() {
    return <h2>Hello {this.yearsTranslation()}!</h2>;
  }
}

export default Car;

只需将 prop 传递下去，就像这样:

class Intl extends React.Component {
  render() {
    return (
      <div>
        <h1>Who lives in my garage?</h1>
        <Car brand="Ford" intl={this.props.intl}/>
      </div>
    );
  }
}

export default injectIntl(Intl);
