使用 express-fileupload 上传文件不起作用

Uploading a file with express-fileupload doesn't work

我正在尝试在 Node js 中使用 express-fileupload (express-fileupload) 上传文件。 但是我还没有成功。

我的app.js(我的快递服务器是运行)看起来像这样:

const express = require('express');
const exphbs = require('express-handlebars');
const fileUpload = require('express-fileupload');

const app = express();
const port = 5000;

app.use(fileUpload({
  debug: true
}));

app.use(express.static('./upload'));

const routes = require('./server/routes/task');
app.use('/', routes);

app.listen(port, () => console.log(`Listening on port ${port}`));

我的 task.js(我的路线所在的位置)如下所示:

const express = require('express');
const router = express.Router();
const taskController = require('../controllers/taskController');

router.post('/admin/fileUpload', taskController.fileUpload);

module.exports = router;

我的taskController.js(我的路线受到控制)看起来像这样:

exports.fileUpload = (req, res) => {

  let sampleFile;
  let uploadPath;

  if (!req.files || Object.keys(req.files).length === 0) {
    res.render('admin', { error: `No files were uploaded!` });
  } else {
    sampleFile = req.files.sampleFile;
    uploadPath = __dirname + '/upload/' + sampleFile.name;
    sampleFile.mv(uploadPath, function (err) {
      if (err) throw err;
      res.render('admin', { alert: `File ${sampleFile.name} successfully uploaded!` });
    }
  }
}

我的 admin.hbs(我也在使用 express-handlebars)看起来像这样:

<form method="POST" action="/admin/fileUpload">
  <h2>Upload File</h2>
  <input type="file" enctype="multipart/form-data" name="sampleFile">
  <button type="submit">
</form>

因此,当我启动 express 服务器时,我的日志如下所示:

[nodemon] starting `node app.js`
Listening on port 5000
Express-file-upload: Request is not eligible for file upload!

我花了几个小时试图找到问题,但还没有成功。

所以,我花了一段时间才找到我的问题。

我在表单和上传路径中犯了两个小错误。

<form method="POST" action="/admin/fileUpload">
 <h2>Upload File</h2>
 <input type="file" enctype="multipart/form-data" name="sampleFile">
 <button type="submit">
</form>

错了。我在错误的地方添加了“enctype”。它应该在表单中而不是在输入字段中。

我的表单的解决方案:

<form method="POST" action="/admin/fileUpload" enctype="multipart/form-data">
 <h2>Upload File</h2>
 <input type="file" name="sampleFile">
 <button type="submit">
</form>

我上传路径的解决方法:

而不是

uploadPath = __dirname + '/upload/' + sampleFile.name;

我需要这样做

uploadPath = './upload/' + sampleFile.name;
