使用NodeJs上传文件

const http = require('http');
const formidable = require('formidable');

http.createServer(function(req, res) {
  if (req.url == '/upload' && req.method.toLowerCase() == 'post') {
    const form = new formidable.IncomingForm();
    form.parse(req, function(err, fields, files) {
      if (err) throw err;
      // 文件临时路径
      const tempPath = files.file.path;
      // 文件保存路径
      const newPath = '/path/to/save/' + files.file.name;
      // 将文件从临时路径移动到保存路径
      fs.rename(tempPath, newPath, function(err) {
        if (err) throw err;
        res.end('File uploaded and moved!');
      });
    });
  } else {
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.write('<form action="/upload" method="post" enctype="multipart/form-data">');
    res.write('<input type="file" name="file"><br>');
    res.write('<input type="submit" value="Upload">');
    res.write('</form>');
    return res.end();
  }
}).listen(8080);
