<p>我在我的项目中遇到了一些钩子问题。这是一个用于检查用户权限并返回true或false的函数。</p> <pre class="brush:php;toolbar:false;">import { useSelector } from "react-redux"; const CheckPermission = (module_key, permission_key) =&gt; { const { user } = useSelector((state) =&gt; ({ user: state.auth.user, })); const rolePermissions = user?.role?.role_permissions ?? []; const return_value = !!rolePermissions.find( (p_list) =&gt; p_list.module?.key === module_key &amp;&amp; p_list.permission?.key === permission_key ); return return_value; }; export default CheckPermission;</pre> <p>然后我在我的侧边栏组件中使用它</p> <pre class="brush:php;toolbar:false;">const renderMenu = (menu, key) =&gt; { if (!CheckPermission(menu.moduleKey, menu.permissionKey)) { return null; } return ( &lt;Tooltip title={menu.name} placement="right" key={key}&gt; &lt;NavLink activeClassName={styles.active} exact className={styles.item} to={menu.path} &gt; &lt;span className={styles.iconBox}&gt;{menu.icon}&lt;/span&gt; &lt;span className={styles.itemText}&gt; {menu.name}&lt;/span&gt; &lt;/NavLink&gt; &lt;/Tooltip&gt; ); }; export default ({ collapse, onCollapse, isAdmin }) =&gt; { const { user } = useSelector((state) =&gt; ({ user: state.auth.user, })); return ( &lt;Layout.Sider theme="light" className={classnames(styles.sider, collapse ? styles.collapsed : "")} collapsible collapsed={collapse} onCollapse={onCollapse} width={collapse ? 64 : 264} onBreakpoint={() =&gt; {}} breakpoint="xl" style={{ overflow: "auto", height: "100vh", position: "fixed", left: 0, top: 0, paddingTop: "50px", }} &gt; &lt;div className={styles.action}&gt; {user &amp;&amp; user.read_only ? menus.map((menu, i) =&gt; { if (menu.name === "Харилцагч") { return renderMenu(menu, i); } else { return ( menu &amp;&amp; menu.children &amp;&amp; // eslint-disable-next-line array-callback-return menu.children.map((submenu, j) =&gt; { if (submenu.name === "QR данс") { return ( &lt;div key={i} className={styles.parentnav}&gt; {renderMenu(submenu, j)} &lt;/div&gt; ); } }) ); } }) : menus.map((menu, i) =&gt; { if (menu.path) { return renderMenu(menu, i); } else { return ( &lt;div key={i} className={styles.parentnav}&gt; {menu.name ?
