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

Question

是否不允许在高阶组件内部使用钩子？当我尝试用这个简单的模式来做时，我收到了错误 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;

Answer 1

我相信你应该使用 HOC 中的钩子：

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

受 Rafael Souza 的回答启发，您可以通过以下方式使其更加清晰：

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