我无法弄清楚我错过了哪些地方。当我点击Cannot GET /portal/destroybox/5797318673cf3f581163455c中的删除或更新图标时出现以下错误：portal.ejs：
（createbox中的portal.ejs工作并创建项目并将其存储在数据库中，然后我在表格中forEach显示所有项目，每个项目后面都有更新和删除图标。此外，server.js中的// todo test部分是针对我的应用程序的另一部分而且有效，与门户/盒子部分无关。我在server.js中也没有创建路由器的路由，但是那部分是有效的，那么如果我需要它，为什么我需要它为destroybox？）
portal.ejs

答案 0 :(得分：1)
因为您没有路由，因为错误说明：
app.get('/destroybox/:id'
您可以看到您的路线从 root /到 destroybox 然后：id 等。当您有href：
href="/portal/destroybox/<%= box._id %>"
从 root /到门户，然后 destroybox ，然后 id 。哪个在配置中没有定义。
解决方案是将href更改为：
href="/destroybox/<%= box._id %>"
其他href属性也是如此。
