我的代码:
Js文件:
UPDATE table t LEFT JOIN
(SELECT min(id) as minid, option1, option2, option3, option4
FROM t
GROUP BY option1, option2, option3, option4
) tt
ON t.id = tt.minid
SET t.option2 = (CASE WHEN tt.minid IS NOT NULL THEN LOWEST ELSE NOT_LOWEST END)
WHERE option1 = 'a';
Html / Ejs文件:
var formidable = require('formidable');
var fs = require('fs');
var ex = require('express');
var fse = require('fs-extra');
var app = ex();
app.set('view engine', 'ejs');
app.get('/form', function(req, res) {
res.render(__dirname + '/views/front.ejs', {title: 'form-page'});
}).listen(8081);
app.post('/form', function(req, res) {
var form = new formidable.IncomingForm();
form.parse(req, function (err, fields, files) {
var oldpath = files.fil.path;
var newpath = __dirname + '/uploads/' + files.fil.name;
var fileExt = files.fil.name.split('.').pop();
fse.move (oldpath, newpath, function (err) {
if (err) { throw err; }
});
});
});
所有软件包都已正确安装,使用此代码,文件(具有任何扩展名)将正确上载到所需目录。
我想要的只是上传图像文件: - jpeg,png等 谢谢。
答案 0 :(得分:1)
使用此代码:
form.onPart = function (part) {
if(!part.filename || part.filename.match(/\.(jpg|jpeg|png)$/i)) {
this.handlePart(part);
}
else {
console.log(part.filename + ' is not allowed');
}
}
