1.引用semantic 中的 menu 時menu不能隱藏，不是那邊的script腳本問題，那麼就是menu的問題，看了半小時沒發現哪裏有錯，刪到就剩menu發現my:<menu> semantic:<div class='menu'>
2.定位元素的樣式big.ui.buttons無效，.big.ui.buttons有效div要.
3.404:瀏覽器地址錯誤signup->singup
4.登入後退回重新刷新signup內存泄露警告
5.semantic UI dropdown 無效發現要加JavaScript腳本，但文檔沒說明只有HTML的佈局圖
6.express-session 中的 saveUninitialized : true和false切換無效。後面覺得肯定是哪裏代碼加載時用了session，果然
app.use((req, res, next) => {
res.locals.user = req.session.user
res.locals.success = req.flash('success').toString()
res.locals.error = req.flash('error').toString()
next()
})7.傳值時因爲有error未處理所以傳不過去
app.use(function(req, res, next) {
- var err = new Error('Not Found');
- err.status = 404;
- next(err);
-});
-
-// error handler
-app.use(function(err, req, res, next) {
- // set locals, only providing error in development
- res.locals.message = err.message;
- res.locals.error = req.app.get('env') === 'development' ? err : {};
-
- // render the error page
- res.status(err.status || 500);
- res.render('error');
-});錯誤信息給異常了，沒傳到signup
8.throw new TypeError(‘Router.use() requires middleware function but got a ’ + gettype(fn));
拋出新的類型錯誤（Router.use() 需要中間件函數但是但是得到的是gettype(fn)）
const express = require('express')
const router = express.Router()
router.get('/', (req, res) => {
req.session.user = null
req.flash('success', '登出成功')
res.redirect('/article')
})忘記exportmodule.exports = router
9.TypeError: User.findOne(…).addCreateAt is not a function
.addCreateAt單詞打錯了
10.Cannot GET /posts/5a3a4040ac988e0cc7034da9
地址沒錯，請求方式沒錯，方法錯了，寫個demo一跑就出
11.測試代碼打印一直有問題，發現res.redirect(‘back’) ：
A back redirection redirects the request back to the referer, defaulting to / when the referer is missing.
The HTTP referer (originally a misspelling of referrer[1]) is an HTTP header field that identifies the address of the webpage (i.e. the URI or IRI) that linked to the resource being requested.
重新設置頭部信息
打印res.text有些奇怪不知道爲什麼

發現這問題主要是奇怪爲什麼test中有一條會對，對比後發現的
12.
想保留session發現無限的重定向。debug發現了路由中間件弄的無限回調
13.
表單中修改了名字，還是說未定義，但是單詞都是對的，對比了以前的也一樣，打印了消息發現名字沒用上，找網頁發現沒有刷新，因爲重新提交表單時頁面不會刷新，要重開。
14.
使用提出的函數返回是promise，說then未定義。發現=》{}不能返回=》能返回
