摘要：部署阿里云創建實例添加安全組允許端口使用連接服務器將項目壓縮上傳注表述能力有限如果有什么問題或探討可以加如果對你有幫助勞駕給個

github 在線

1.修復mysql無法訪問

1.安裝vue-cli腳手架

npm install -g vue-cli

2.創建基于webpack模版的項目

vue init webpack my-express

3.安裝包依賴并運行

cd my-express
npm install
npm run dev

vue項目基于iview-admin改造的

1.連接數據庫

在config創建db.js

var mysql = require("mysql");
var connection = mysql.createConnection({
    host:"",
    port: 3306,
    user:"root",
    password:"",
    database:"",
    useConnectionPooling: true
});

function query(sql,data,callback){
    // connection.connect()
    // pool.getConnection(function(err,connection){
        connection.query(sql,data,function (err,rows) {
            callback(err,rows);
            // connection.release();
            // connection.end()  
        });
    // });
}

exports.query = query;

在routers路由文件下引入

var express = require("express");
var router = express.Router();
var db = require("../config/db");
const jwt = require("jsonwebtoken")
const token = require("../config/token")
var data={data:"",meta:{code:"200",message:""}}
/* GET users listing. */
router.post("/add", function(req, res, next) {
    let username = req.body.username;
    let password = req.body.password;
    db.query("SELECT username FROM users where username=(?)",[username],function(err,rows){
        console.log(err,rows)
        if(rows.length>0){
            data={data:"",meta:{code:"500",message:"用戶名存在"}}
            res.send(data)
        }else{
            db.query("INSERT INTO `users` (`username`,`password`) VALUES (?,?)",[username,password],function(err,rows){
                data={data:"",meta:{code:"200",message:"注冊成功"}}
                res.send(data)
            });   
        }
    });
});

2.加入token驗證

安裝jsonwebtoken

npm install jsonwebtoken

在config創建token.js

const crypto = require("jsonwebtoken")
const secret = "JWT-TOKEN"
const token={
    createToken:function(obj,timeout){
        // Token 數據
        let payload = {
            name: obj.username,
            admin: true
        };
        // 密鑰
        
        // 簽發 Token
        let tokens = crypto.sign(payload, secret, { expiresIn: 3600})
        return  tokens;
    },
    decodeToken:function(tokens){
        console.log(tokens)
        let res = false;
        crypto.verify(tokens, secret , function(err,decoded) {
            if(err){
                res = {"flag":false,"decoded":decoded}
            }else{
                res = {"flag":true,"decoded":decoded}
            }
            })
        return res;
    },
    checkToken:function(token){
        var resDecode=this.decodeToken(token);
        if(!resDecode){
            return false;
        }
        //是否過期
        var expState=(parseInt(Date.now()/1000)-parseInt(resDecode.payload.created))>parseInt(resDecode.payload.exp)?false:true;
        if(resDecode.signature===resDecode.checkSignature&&expState){
            return true;
        }
        return false;
    }
};
module.exports=exports=token;

在app.js驗證token是否過期，過去返回401

app.all("*", function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Methods", "PUT, GET, POST, DELETE, OPTIONS");
    res.header("Access-Control-Allow-Headers", "Content-Type, access_token, X-Requested-With")
    // res.header("Content-Type", "application/json;charset=utf-8");
    console.log(req.originalUrl,"11111")
    if(rouetpass.indexOf(req.originalUrl) > -1 || req.originalUrl.split("/").indexOf("static") > -1){

        next()
    }else{
        if (req.method != "OPTIONS"){
            var accesstoken = req.headers["access_token"];
            let datatoken = token.decodeToken(accesstoken)
            // console.log(data)
            if(datatoken.flag){
                next()
            }else{
                data.meta.code=401;
                res.send(data) 
            }
        }else{
            next()
        }
    }
});

1.將vue項目打包后放在express項目public文件夾下，通http://localhost:3000即可以訪問。

2.部署阿里云

創建實例

添加安全組允許3000端口

使用putty連接linux服務器,將express項目壓縮上傳
