Question

我在很多组件中使用了几个大对象，所以我为每个大对象创建了一个proptypes文件，如下所示：

PropTypes/PropLargeObject.js

其中包含从＆＃34; prop-types＆＃34;;

导入PropTypes

const PropLargeObject =
    PropTypes.shape({
        id: PropTypes.number.isRequired, 
        name: PropTypes.string.isRequired,
        items: PropTypes.ArrayOf(PropTypes.Shape({
            itemId: PropTypes.number.isRequired,
            itemName: PropTypes.string.isRequired 
        }))
    });

export default PropLargeObject;

我在我的组件中使用这样的对象：

import {PropLargeObject} from "./PropTypes/PropLargeObject";

Component.propTypes = {
    LargeObject: {PropLargeObject}
}

它给了我警告Prop类型＆＃34; PropLargeObject＆＃34;无效它必须是一个函数，通常来自React.PropTypes。我在这里做错了什么？

删除不必要的花括号：

import PropLargeObject from "./PropTypes/PropLargeObject"; // PropLargeObject is the default export

Component.propTypes = {
    LargeObject: PropLargeObject // PropLargeObject is a PropTypes.shape function. Don't wrap with an object
}

你甚至可以将它缩短一点：

import LargeObject from "./PropTypes/PropLargeObject"; // you can assign whatever name you want to default imports

Component.propTypes = {
    LargeObject
}

React PropTypes导入类。道具类型无效
