我在Express中有一个应用程序,我需要上传一个文件,我目前正在使用express-fileupload,在我做的测试中我没有遇到任何问题:
const fs = require('fs');
const fileUpload = require('express-fileupload');
const resizeImg = require('resize-img');
app.post('/upload', function(req, res) {
if (!req.files)
return res.status(400).send('No files were uploaded.');
let sampleFile = req.files.sampleFile;
var d = new Date();
var newName = d.getHours()+'-'+d.getMinutes()+'-'+d.getSeconds()+'.jpg';
console.log(newName)
var rImage = 'C:/Developer/node/express-fileuploadWebix/public/images/'+newName;
sampleFile.mv(rImage, function(err) {
if (err)
{
return res.status(500).send(err);
}
resizeImg(fs.readFileSync(rImage), {width: 130, height: 180}).then(buf => {
fs.writeFileSync(rImage, buf);
});
res.send('File uploaded!');
});
});
req.files.sampleFile有数据!
但是当我向我的app.js添加express-session时更改req和req.files不再存在
答案 0 :(得分:1)
要实际运行fileUpload
中间件,您需要在请求处理程序之前添加以下代码行:
app.use(fileUpload());
