问题描述

使用HOC不支持包裹函数组件, 会被编译为React.createElement

复现步骤

import Taro from '@tarojs/taro';
import useTokenProcessor from '../hooks/useTokenProcessor';

const withUseTokenProcessor = (OutComponent) => {
  return props => {
    const [isLoading, isNeedAuth] = useTokenProcessor();
    return (
      <OutComponent isLoading={isLoading} isNeedAuth={isNeedAuth} {...props} />
    );
  };
};

export default withUseTokenProcessor;

将此HOC引入页面使用后, 出现报错, 提示Uncaught ReferenceError: React is not defined

可以看到, 这个HOC被编译成为了一个使用React.createElement生成的组件

主要的想法是想将hooks的逻辑复用到原有的class组件中, 所以使用hoc

小程序端暂时不支持 HOC,因为不能劫持 render 方法
