Question

我的server.js代码：

var express = require('express');
var app = express();


// set the view engine to ejs
app.set('view engine', 'ejs');
app.use(express.static(__dirname + '/dist'));
if (par.query.login) {


var data={
    "user": {
        "displayName": "fares alkhawaja",
        "username": "elkhawajah"
    },
    "profile": {
             "photo":"null",
             "fullName": "fares sameer alkhawaja"   
    },
    "balance": {
        "overall": 200,
        "outstanding": 149
    },
    "currentTasks": [{
        "isProject": false,
        "id": "1234",
        "title": "Build NodeJS Application",
        "description": "This is a description for building nodejs application",
        "prize": "$500",
        "project": "topcoder",
        "holder": "elkhawajah"
    }, {
        "id": "134",
        "isProject": false,
        "title": "Build NodeJS Application",
        "description": "This is a description for building nodejs application",
        "prize": "$500",

        "holder": "elkhawajah"
    }],
    "pastTasks": [{
        "isProject": false,
        "id": "1",
        "title": "Build NodeJS Application",

        "prize": "$500",

        "id": "2",
        "isProject": false,
        "title": "Build NodeJS Application",
        "description": "This is a description for building nodejs application",
        "prize": "$500",
        "project": "topcoder",
        "holder": "fares"
    }, {
        "id": "3",
        "isProject": true,
        "title": "Build NodeJS Application",
        "description": "This is a description for building nodejs application",
        "prize": "$500",
        "project": "topcoder",
        "holder": "fares"
    }],
    "timeline": [{
        "title": "Fares uploaded a new submission",
        "project": "tasqat",
        "task": "Build new endpoint",
        "date": new Date(),
        "handle": "fares"
    }, {
        "title": "Fares uploaded a new submission",
        "project": "tasqat",
        "task": "Build new endpoint",
        "date": new Date(),
        "handle": "fares"
    }]
}
}  
app.get("/dashboard", function(req, res) {

//send Jsondata to /view/dashboard.ejs
res.render('dashboard', data);

});

app.listen(process.env.PORT);
console.log(process.env.PORT + ' is the magic port');

我的问题是我需要使用req.query.login ...如果req.query.login {return data} else {return nothing}

例如..当我使用http://localhost:3000/dashboard数据时，如果用户登录http://localhost:3000/dashboard?login=true应该返回数据，那么应该只返回任何帮助吗？

根据您的要求，具有query params

条件的样本控制器

var userData = {...}; //your data for user

您的控制器将是这样的

app.get("/dashboard", function(req, res) {

  var isLoggedIn = req.query.login; //assuming route as /dashboard?login=true
  var data = isLoggedIn? userData : {}; //empty object or null, whatever you want

  res.render('dashboard', data);

});

用于查询的json数据条件
