四、MySQL数据
connection.js：
var mysql=require("mysql");
var setting=require("./setting");
var connection;
var connectionmysql=function(){
connection=mysql.createConnection({
host:setting.host,
port:setting.port,
user:setting.user,
password:setting.pwd,
database:setting.base
});
}
connectionmysql(); //初始化连接数据库
// 不带参
exports.select=function(str,callback){
connectionmysql(); //重新连接数据库
connection.query(str,function(err,res){
if(err) throw err;
callback(res);
connection.end(); //关闭服务器
});
}
// 带参
exports.find=function(str,params,callback){
connectionmysql(); //重新连接数据库
connection.query(str,params,function(err,res){
if(err) throw err;
callback(res);
connection.end(); //关闭服务器
});
}
sql.js：
module.exports={
findTitle:"select * from nav",
templateBlog:"select * from template where template.id=?",
allTemplate:"select * from template"
}
promise.js：
var mysql=require("../MySQL/connection");
var sql=require("../MySQL/sql");
module.exports={
findTitle:function(){
return new Promise(function(resolve){
mysql.select(sql.findTitle,function(result){
resolve(JSON.parse(JSON.stringify(result)));
});
})
},
templateBlog:function(id){
return new Promise(function(resolve){
mysql.find(sql.templateBlog,id,function(result){
resolve(JSON.parse(JSON.stringify(result)));
});
});
},
allTemplate:function(){
return new Promise(function(resolve){
mysql.select(sql.allTemplate,function(result){
resolve(JSON.parse(JSON.stringify(result)));
});
});
}
}
router.js：
var promise=require("../MySQL/promise");
module.exports=function(app){
app.get("/cms",function(req,res){
async function getData(){
var res1=await promise.findTitle();
var res16=await promise.allTemplate();
var allres={
titleindex:2,
navres:res1,
allcmsres:res16
}
return allres;
}
getData().then(function(result){
res.render("cms",result);
});
});
app.get("/cmsdetail",function(req,res){
var cmsid=req.query.id;
if(!cmsid){
res.send("404");
return;
}
async function getData(){
var res1=await promise.findTitle();
var res14=await promise.templateBlog(cmsid);
var allres={
titleindex:2,
navres:res1,
cmsblogres:res14
}
return allres;
}
getData().then(function(result){
res.render("cmsdetail",result);
});
});
}
