我在express.js上遇到路由错误。我正在使用jade来呈现我的页面浏览量。我已阅读所有文档并多次重构无济于事。
这是指向＆＃39; / sell＆＃39;的链接的简单内容。路由。
index.jade
include layout
html
button.btn.btn-primary(type='submit', href='/sell') Add Item
单击此按钮时，浏览器会将以下内容作为404返回：
无法获取/出售
这里的问题是，如果要将上述href修改为其他页面，即＆＃39; /＆＃39; ，＆＃39; / sign_in＆＃39;等没有错误发生。这个问题似乎被隔离到＆＃39; / sell＆＃39;路由。
带有＆＃39; / sell＆＃39;的控制器路线如下：

答案 0 :(得分：2)
我认为它以表格形式发布并试图联系app.post（＆＃39; / sell＆＃39;）
改变它：
button.btn.btn-primary(type='submit', href='/sell') Add Item
为：
a.btn.btn-primary(href='/sell') Add Item
还会移除部分中间件并仅保留以下这些行：
app.set('views', 'app/views');
app.set('view engine', 'jade');
app.set('port', process.env.PORT || 3000);
app.use(logger('dev'));
然后在您的浏览器中导航到/卖出路线，检查它是否正常工作 如果是 - 我们删除了要检查的中间件之一的问题。
答案 1 :(得分：0)
您应该添加一个记录器中间件，并查看当您尝试转到该路由时服务器提供的错误。另一件事是重命名卖出路线，看看是否有效。这可能表明与您的另一条路线发生冲突，虽然目前尚不清楚查看您的代码的位置。
