node.js - 如何让文件上传图像显示在某些URL Node JS上

转载作者：太空宇宙更新时间：2023-11-04 02:37:03

我是 Node JS 新手，我已经成功创建了一个允许文件上传的页面，并在浏览器中显示图像。我遇到的唯一问题是它显示到一个页面，并将文件名附加到 URL 末尾，如下所示: localhost:8888/tmp/car.png我希望能够在浏览器中看到它，网址如下:本地主机:8888/汽车

任何建议，我们将不胜感激，谢谢!!!!

var express = require("express");
var app = express()

 /// Include the express body parser
 app.configure(function () {
 app.use(express.bodyParser());
});

var form = "<!DOCTYPE HTML><html><body>" +
"<form method='post' action='/upload' enctype='multipart/form-data'>" +
"<input type='file' name='image'/>" +
"<input type='submit' /></form>" +
"</body></html>";

app.get('/', function (req, res){
    res.writeHead(200, {'Content-Type': 'text/html' });
    res.end(form);

  });

 /// Include the node file module
 var fs = require('fs');

 /// Post files
  app.post('/upload', function(req, res) {

    fs.readFile(req.files.image.path, function (err, data) {

    var imageName = req.files.image.name

    /// If there's an error
    if(!imageName){

        console.log("There was an error")
        res.redirect("/");
        res.end();

    } else {

      var newPath = __dirname + "/uploads/fullsize/" + imageName;

      /// write file to uploads/fullsize folder
      fs.writeFile(newPath, data, function (err) {

        /// let's see it
        res.redirect("/uploads/fullsize/" + imageName);

      });
                }
        });
   });

         app.listen(8888)
