如何在自定义验证器中使用PropType内置函数？

import PropTypes from 'prop-types';

YourComponent.propTypes = {
  name: function(props, propName, componentName) {
    if (typeof props[propName] !== 'string') {
      return new Error(`Invalid prop ${propName} supplied to ${componentName}. Expected a string.`);
    }
    if (props[propName].length > 10) {
      return new Error(`Invalid prop ${propName} supplied to ${componentName}. Length should not exceed 10 characters.`);
    }
  }
};

class YourComponent extends React.Component {
  render() {
    // ...
  }
}

YourComponent.propTypes = {
  name: function(props, propName, componentName) {
    // 自定义验证器的实现
  }
};
