在全局中重定向所有尾部斜杠 [英] Redirect all trailing slashes globally in express

问题描述

我正在使用Node.js和Express，我有以下路由：

  app.get（'/' function（req，res）{
 locals.date = new Date（）toLocaleDateString（）; 
 
 res.render（'home.ejs'，localals）; 
} ）; 
 
函数lessonsRouter（req，res，next）
 {
 var lesson = req.params.lesson; 
 res.render（'lessons /'+ lesson +'.ejs'，locals_lessons）; 
} 
 
 app.get（'/ lessons /：lesson *'，lessonsRouter）; 
 
 
函数viewsRouter（req，res，next）
 {
 var controllerName = req.params.controllerName; 
 res.render（controllerName +'.ejs'，locals_lessons）; 
} 
 app.get（'/：controllerName'，viewsRouter）;我有一个 Disqus 
 
 $一个>我的课程页面上的小部件，我注意到一个奇怪的行为，当去 myapp.com/lessons 和 myapp.com/lessons/ 我得到两个不同的页面（其中有一个我以前在Disqus中添加的评论，另一个没有评论）。
 
 
 
有没有办法封存我所有的网址，没有拖尾？我试图添加 strict routing 标志来表达，但结果是一样的
 
 
 
谢谢
解决方案
尝试添加一个中间件; 
  app.use（function（req，res，next）{
 if（req.url.substr（-1）=='/'& req.url.length> 1）
 res.redirect（301，req.url.slice（0，-1））; 
 else 
 next（）; 
}）; 
  
 
I am using Node.js and Express and I have the following routing :
app.get('/', function(req,res){
    locals.date = new Date().toLocaleDateString();

    res.render('home.ejs', locals);
});

function lessonsRouter (req, res, next)
{
    var lesson = req.params.lesson;
    res.render('lessons/' + lesson + '.ejs', locals_lessons);
}

app.get('/lessons/:lesson*', lessonsRouter);


function viewsRouter (req, res, next)
{
    var controllerName = req.params.controllerName;
    res.render(controllerName + '.ejs', locals_lessons);
}
app.get('/:controllerName', viewsRouter);
I have a Disqus widget on my lessons pages and I have noticed a strange behavior that when going to myapp.com/lessons and myapp.com/lessons/ I get two different pages (on of them had a comment I previously added in Disqus and the other one doesn't have a comment).

Is there a way to "canonize" all of my urls to be without trailing slashes ? I have tried to add the strict routing flag to express but the results were the same

Thanks 
解决方案
Try adding a middleware for that;
app.use(function(req, res, next) {
   if(req.url.substr(-1) == '/' && req.url.length > 1)
       res.redirect(301, req.url.slice(0, -1));
   else
       next();
});
