nodejs cookie和token设置
链接MySQL数据库
在数据建立完整后，在node中操作链接
/**数据库**/ var Client = require('mysql').createConnection({ host: '127.0.0.1', user: 'root', password: '*******', database: '********', charset: 'UTF8',
}); 查询数据库
var querStr = `select * from 表名 where 条件`;
Client.query(
querStr, function selectCb(err, results, fields) { if (err) { throw err;
}
}); 后台登录cookie
-
设置cookie
var serialize = function(name, val, opt) {
var pairs = [name + '=' + val];
opt = opt || {};
if (opt.maxAge) pairs.push('Max-Age=' + opt.maxAge);
if (opt.domain) pairs.push('Domain=' + opt.domain);
if (opt.path) pairs.push('Path=' + opt.path);
if (opt.expires) pairs.push('Expires=' + opt.exppires.toUTCString());
if (opt.httpOnly) pairs.push('HttpOnly');
if (opt.secure) pairs.push('Secure');
return pairs.join(';');
}; -
登录匹配成功后设置cookie
res.setHeader('Set-Cookie', serialize('isVisit', '1'));
3.代码
var serialize = function(name, val, opt) { var pairs = [name + '=' + val];
opt = opt || {}; if (opt.maxAge) pairs.push('Max-Age=' + opt.maxAge); if (opt.domain) pairs.push('Domain=' + opt.domain); if (opt.path) pairs.push('Path=' + opt.path); if (opt.expires) pairs.push('Expires=' + opt.exppires.toUTCString()); if (opt.httpOnly) pairs.push('HttpOnly'); if (opt.secure) pairs.push('Secure'); return pairs.join(';');
};
router.post('/login', function(req, res) { var username = req.body.username; var password = req.body.password; var querStr = `select * from adminuser where username = '${username}' and password ='${password}'`;
Client.query(
querStr, function selectCb(err, results, fields) { if (err) {
data = {state: 0, results: ''}; throw err;
} if (results.length === 0) {
data = {state: 0, results: ''};
} else {
data = {state: 1, results: "登录成功"};
}
res.setHeader('Set-Cookie', serialize('isVisit', '1'));
res.json(data);
});
}); 4.下次请求时验证
if (!req.cookies.isVisit) { console.log('用户未授权');
res.json(unlogin);
} else {
} 移动端设置token
1.npm导入
npm install jwt-simple
2.设置
var express = require('express'); var jwt = require('jwt-simple'); var app = express();
app.set('jwtTokenSecret', 'YOUR_SECRET_STRING'); 3.匹配成功设置token
/**设置移动端登录连续七天过后过期**/ var expires = moment().add(7, 'days').valueOf(); var token = jwt.encode({ iss: results.id, exp: expires,
}, app.get('jwtTokenSecret')); 4.全部代码
/**用户登录接口**/ router.post('/mobile/login', function(req, res) { var username = req.body.username; var password = req.body.password; var querStr = `select * from “表名” where username = '${username}' and password = '${password}'`;
Client.query(
querStr, function selectCb(err, results, fields) { if (err) {
data = {state: 0, results: ''}; throw err;
} if (results.length === 0) {
data = {state: 0, results: ''};
} else { /**设置移动端登录连续七天过后过期**/ var expires = moment().add(7, 'days').valueOf(); var token = jwt.encode({ iss: results.id, exp: expires,
}, app.get('jwtTokenSecret'));
data = {state: 1, results: results, token: token};
}
res.json(data);
});
}); 5.下次请求验证
var decoded = jwt.decode(token, app.get('jwtTokenSecret')); if (decoded.exp <= Date.now()) { console.log('授权错误');
res.json(unlogin);
} else {
