connect-flash 的使用分享
最近在express框架处理页面消息提示使用了 connect-flash 感觉不错 因为 connect-flash 是需要存储在 session 模块,需要安装 express-session
安装:
npm install express-session
npm install connect-flash
配置app.js:
var flash = require('connect-flash');
var session = require('express-session');
app.use(session({
secret: hibaby,
key: fuckbaby,
cookie: {maxAge: 60000},
resave: false,
saveUninitialized: true,
}));
app.use(flash());
// 设置 error info两个变量信息
app.use(function (req, res, next) {
res.locals.errors = req.flash('error');
res.locals.infos = req.flash('info');
next();
});
处理使用:
userPost : function(req, res, next){
var data = req.body;
var addSql = "INSERT INTO project(id, type, project, version, name, url, person, pm, ui) VALUES(0, "+'\''+data.type+'\''+", "+'\''+data. project+'\''+", "+'\''+data.version+'\''+", "+'\''+data.name+'\''+", "+'\''+data.url+'\''+", "+'\''+data.person+'\''+", "+'\''+data.pm+'\''+", "+'\''+data.ui+'\''+")";
if(data.type == '' || data.project == '' || data.version == '' || data.name == '' || data.url == '' || data.person == '' || data.pm == '' || data.ui === ''){
req.flash('error','信息填写错误!');
return res.redirect('/guidepc?edit=fed');
}else{
query(addSql, function (err, result, fields) {
if(err){
console.log('[INSERT ERROR] - ', err.message);
req.flash('error','database error!');
return res.redirect('/guide');
}else{
req.flash('info','执行成功!');
return res.redirect('/guide');
}
});
}
}
handlebars :
<div id="message"> {{errors}} {{infos}}</div>
测试:
路由位置很关键!!
