javascript - 在 HOC 中使用 useState/Hooks 使用react导致错误 "Hooks can only be called inside of the body of a function component"

Question

不允许在高阶组件内使用钩子(Hook)吗？当我尝试使用这个简单的模式时，我得到了错误 Invalid hook call. Hooks can only be called inside of the body of a function component.

// App.js
import React, { useState } from 'react';

const WithState = (Component) => {
  const [state, dispatch] = useState(0);
  return () => <Component state={state} dispatch={dispatch} />;
}

const Counter = ({ state }) => {
  return (
    <div style={{ textAlign: 'center', margin: '0 auto'}}>
      {state}
    </div>
  )
}

const CounterWithState = WithState(Counter);

const App = () => {
  return <CounterWithState />;
}

export default App;

我相信你应该使用 HOC 内部的钩子(Hook):

const WithState = (Component) => {
  const WithStateComponent = () => {
    const [state, dispatch] = useState(0);
    return <Component state={state} dispatch={dispatch} />;
  }
  return WithStateComponent;
}
