node.js – 基于环回redis的会话

首先,我想说我已经看到有关相关问题的问题,但没有找到答案.

我想在环回中使用redis进行会话,但是代码中没有req.

server/server.js

var redis   = require("redis");
var session = require('express-session');
var redisStore = require('connect-redis')(session);
var client  = redis.createClient();

var app = module.exports = loopback();

app.use(session({
    secret: '0`3VTw;hQ|3/`:95ZYu{0J82O>{}7JC/',
    // create new redis store.
    store: new redisStore({ host: 'localhost', port: 6379, client: client,ttl :  260}),
    saveUninitialized: false,
    resave: false
}));

我想在环回应用程序上实现基于Redis的快速会话,但是我无法在不自己编写整个路由控制器的情况下找到方法.

我目前正在扩展模型并创建一个remoteMethod(),但无论如何我都无法访问“req”.

这是我的TrmptUsers模型代码(见第3行)

common/models/trmpt-users.js

module.exports = function(TrmptUsers) {
 TrmptUsers.login = function(username, password, cb) {
    console.log(TrmptUsers.app.session); //i want access to req variable to work with redis here.
 var ursalt = security.gen_salt(username);
        password = security.decrypt256(password, ursalt);
        TrmptUsers.findOne({fields:{usrPwd:true,usrAccessToken:true},where:{and:[{usr_username:username}]}},function(err,result){
        security.verifyPassword(password, result.usrPwd, function(err, verify) {
                if (verify) {
                User.generateVerificationToken(username, cb)
                    cb(null,result.usrAccessToken);
                }
                else {
                   cb({status:401,message:"Invalid Username/Password"},null);   
                }
            });
        });
    }
    TrmptUsers.remoteMethod(
        'login', 
        {
          accepts: [
          {arg: 'username', type: 'string', required: 'true'},
          {arg: 'password', type: 'string', required: 'true'},
          ],
          returns: {arg: 'accesstoken', type: 'string'}
        }
    );
};

很久以前我找到了解决我所有问题的方法,因为有人投了票,我想他们可能想要答案,所以我在这里发帖.

服务器/ server.js

var redis   = require("redis");
var session = require('express-session');
var redisStore = require('connect-redis')(session);
app.use(session({
    secret: 'hello',
    store: new redisStore({ host: 'localhost', port: 6379, client: client,ttl :  3600}),//1 hour
    saveUninitialized: false,
    resave: false
}));

然后在创建模型slc：loopback模型时,您可以选择将req对象添加到参数中.

模型specific.json

...
"methods": {
    "userLogin": {
      "isStatic": true,
      "accepts": [
        {
          "arg": "req",
          "type": "object",
          "required": true,
          "description": "",
          "http": {
            "source": "req"
          }
        },
        {
          "arg": "username",
          "type": "string",
          "required": true,
          "description": "Username"
        },
        {
          "arg": "password",
          "type": "string",
          "required": true,
          "description": "Password"
        }
      ],
      "returns": [
        {
          "arg": "accessToken",
          "type": "string",
          "root": false,
          "description": ""
        }
      ],
...

然后以您想要的任何方式使用req.session,并记住首先安装redis-server.
