Question

每当我尝试使用node.js将form.js文件（res.redirect("/");）重定向到同一页面时，它都起作用！

但是，当我尝试使用welcome.ejs重定向到同一文件夹中的另一个文件（res.redirect("/welcome");）时，它将无法正常工作。

我的welcome.ejs文件中<h1>Welcome Home</h1>就是这个句子。

我的mysql数据库工作正常，我可以看到消息“受影响的行”。所以我很确定那里没有问题。我什至没有任何错误。

我不明白为什么我不能重定向到welcome.ejs页，但是我可以重定向到主页（home.ejs或"/"）。在浏览器中，消息显示“无法获得/欢迎”

我什至尝试返回res.redirect(/welcome)或res.redirect("/welcome.ejs")，但没有成功！

我的文件夹结构为views/home.ejs和views/welcome.ejs。

有人可以帮我吗？

这是我的form.js代码

  app.get('/accountform', function(req, res) {
  var q = "SELECT COUNT(*) AS count FROM `Projects`";
  connection.query(q, function(err, results){

    if (err) throw err;
    var count = results[0].count;
    //res.send("We have " + count + " no of users.");
    res.render("accountform", {count: count});
   });

 app.post('/addproject', function(req, res){
  var project = {
   Project_No: req.body.Project_No,
   Project_Name: req.body.Project_Name,
   Status: req.body.Status,
   Project_Type: req.body.Project_Type

  };
  connection.query('insert into `Projects` SET ?', project, function(err, 
  result){
  console.log(err);
  console.log(result);

  res.redirect("/welcome");
   });
   });
 });

我在您的代码附近尝试了一些

这是我的app.js

    const {getHomePage} = require('./routes/index');
    const {addPlayer} = require('./routes/player');


    app.get('/', getHomePage);
    app.post('/add', addPlayer);

routes / index.js

        module.exports = {
        getHomePage: (req, res) => {
            let query = "SELECT * FROM `players` ORDER BY id ASC"; 
            db.query(query, (err, result) => {
                if (err) {
                    res.redirect('/');
                }
                res.render('index.ejs', {
                    title: "Welcome to Socka | View Players"
                    ,players: result
                });
            });
        },
        };

routes / player.js

         module.exports = {
            addPlayerPage: (req, res) => {
            res.render('add-player.ejs', {
                title: "Welcome to Socka | Add a new player"
                ,message: ''
            });
        },
        addPlayer: (req, res) => {
            if (!req.files) {
                return res.status(400).send("No files were uploaded.");
            }

            let message = '';
            let first_name = req.body.first_name;
            let last_name = req.body.last_name;
            let position = req.body.position;
            let number = req.body.number;
            let username = req.body.username;
            let uploadedFile = req.files.image;
            let image_name = uploadedFile.name;
            let fileExtension = uploadedFile.mimetype.split('/')[1];
            image_name = username + '.' + fileExtension;

            let usernameQuery = "SELECT * FROM `players` WHERE user_name = '" + username + 
                  "'";

            db.query(usernameQuery, (err, result) => {
                if (err) {
                    return res.status(500).send(err);
                }
                if (result.length > 0) {
                    message = 'Username already exists';
                    res.render('add-player.ejs', {
                        message,
                        title: "Welcome to Socka | Add a new player"
                    });
                } else {
                    if (uploadedFile.mimetype === 'image/png' || uploadedFile.mimetype === 
                     'image/jpeg' || uploadedFile.mimetype === 'image/gif') {

                        uploadedFile.mv(`public/assets/img/${image_name}`, (err ) => {
                            if (err) {
                                return res.status(500).send(err);
                            }

                            let query = "INSERT INTO `players` (first_name, last_name, 
                     position, number, image, user_name) VALUES ('" +
                                first_name + "', '" + last_name + "', '" + position + "', '" 
                     + number + "', '" + image_name + "', '" + username + "')";
                            db.query(query, (err, result) => {
                                if (err) {
                                    return res.status(500).send(err);
                                }
                                res.redirect('/');
                            });
                        });
                    } else {
                        message = "Invalid File format. Only 'gif', 'jpeg' and 'png' images 
                    are allowed.";
                        res.render('add-player.ejs', {
                            message,
                            title: "Welcome to Socka | Add a new player"
                        });
                    }
                }
            });
          }
         }

我在views文件夹中有index.ejs和addplayer.ejs

如何重定向到node.js相同文件夹中的其他ejs文件
