Question

我想在id中为值req.params.id指定一个变量，如下所示这是我尝试过的，但不起作用：

＆＃13;

router.get("/users/:id", function(req,res){
     Campground.findById(req.params.id, function(err,foundingdUser){
     var user = foundingdUser.author.id; // i want to use this value for the next findById
      if(err) {
        req.flash("error", "Something went wrong.");
        return res.redirect("/");
      }else{
          User.findById(req.params.user,function(err,foundUser){  // i want to use the value of user here but it is not working
              if(err){
                  req.flash("error","Something went wrong.");
                  return res.redirect("/");
              }else{
                //console.log(foundUser);
                res.render("profile",{use: foundUser})  
              }
          })
      }
    })    
})

您已将id分配给变量用户，因此您应该：

User.findById(user,function(err,foundUser){ ...

或者你可以req.params.user = foundingdUser.author.id;如果你出于某种原因想要这样的话可以保持其余部分

如何将变量分配给node.js中的req.parmas
