font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">动态路由是指通过在路由配置中使用变量来动态生成路由。例如：</p><pre class="brush:as3;toolbar:false">const router = new VueRouter({ routes: [ { path: '/user/:id', component: User } ] })</pre><p class="p1" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">在上面的例子中，我们定义了一个动态路由/user/:id，其中:id表示一个变量，可以根据不同的用户ID动态生成不同的路由。当用户访问/user/1时，就会加载User组件并传递参数id为1。</p><p class="p2" style="margin-top: 0px;

margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">在Vue.js中，可以将组件拆分为更小的组件，然后进行复用。例如，我们可以将页面中的公共部分拆分为组件，然后在需要的地方进行引用。例如：</p><pre class="brush:as3;toolbar:false"><template> <div> <header-nav></header-nav> <router-view></router-view> <footer-nav></footer-nav> </div> </template> <script> import HeaderNav from './HeaderNav.vue' import FooterNav from './FooterNav.vue' export default { name: 'App', components: { HeaderNav, FooterNav } } </script></pre><p class="p3" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "PingFang SC"; white-space: normal;">在上面的例子中，我们将页面中的头部和底部拆分为组件<span class="s1" style="font-variant-numeric: normal;

line-height: normal; font-family: "Helvetica Neue";">App</span>组件中进行引用。这样，无论哪个页面需要头部和底部，都可以直接引用<span class="s1" style="font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";">HeaderNav</span>和<span class="s1" style="font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: normal;

true : false; if (to.meta.requireAuth) { // 判断该路由是否需要登录权限 if (isLogin) { // 判断是否已经登录 next(); } else { next({ path: '/login', query: { redirect: to.fullPath } // 将跳转的路由path作为参数，登录成功后跳转到该路由 }); } } else { next(); } });</pre><p class="p1" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">在上面的例子中，我们定义了一个全局的路由守卫，并在其中进行了登录校验。首先，我们通过localStorage.getItem('token')来判断用户是否已经登录，如果已经登录，那么就可以跳转到目标路由；如果未登录，那么就需要跳转到登录页面进行登录。</p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; min-height: 17px; white-space: normal;"><br/></p><p class="p1" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">在路由配置中设置路由元信息</p><p class="p1" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">为了让路由守卫知道哪些路由需要进行登录校验，需要在路由配置中设置路由元信息。例如：</p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; min-height: 17px; white-space: normal;"><br/></p><pre class="brush:as3;toolbar:false">const routes = [ { path: '/', component: Home, meta: { requireAuth: true // 添加该字段，表示进入这个路由需要登录权限 } }, { path: '/login', component: Login } ];</pre><p class="p1" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">在上面的例子中，我们定义了两个路由，其中Home路由需要进行登录校验，因此在其对应的路由配置中设置了meta: { requireAuth: true }。</p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; min-height: 17px; white-space: normal;"><br/></p><p class="p1" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">通过上面的步骤，就可以实现基础的登录校验功能。当用户访问需要进行登录校验的路由时，会自动跳转到登录页面进行登录；当用户登录成功后，又会自动跳转回目标路由。</p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; min-height: 17px; white-space: normal;"><br/></p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; min-height: 17px; white-space: normal;"><br/></p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; min-height: 17px; white-space: normal;"><br/></p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; min-height: 17px; white-space: normal;"><br/></p><p class="p2" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 15px; line-height: normal; font-family: "Helvetica Neue"; min-height: 17px; white-space: normal;"><br/></p><p><br/></p>
