所以我试图使用request模块/包将我从http调用使用的对象数组循环到我的内部API .到目前为止,我能够从API中获取数据并在我的页面上显示完整对象.我想在我的页面上显示它并使用EJS模板系统循环它.我知道我可以使用AngularJS作为前端的东西,但我想看看我能在多大程度上只用服务器端.
以下是我的代码:
server.js
// Prepend /api to my apiRoutes
app.use('/api', require('./app/api'));
api.js
var Report = require('./models/report');
var express = require('express');
var apiRoutes = express.Router();
apiRoutes.route('/reports', isLoggedIn)
.get(function (req, res,next) {
// use mongoose to get all reports in the database
Report.find(function (err, reports) {
// if there is an error retrieving, send the error.
// nothing after res.send(err) will execute
if (err)
return res.send(err);
res.json(reports);
});
});
routes.js
var User = require('./models/user');
var request = require('request');
module.exports = function (app, passport) {
app.get('/reports', isLoggedIn, function (req, res) {
res.render('pages/new-report.ejs', {
user: req.user,
title:'New Report'
});
});
request({
uri:'http://localhost:2016/api/reports',
method:'GET'
}).on('data',function(data){
console.log('decoded chunk:' + data)
}).on('response',function(resp){
resp.on('data', function(data){
console.log('received:' + data.length + ' bytes of compressed data');
app.get('/timeline', isLoggedIn, function (req, res) {
res.render('pages/timeline', {
user: req.user,
title:'Timeline',
reports: data
});
});
})
});
}
reports.ejs
所以如果我只是在我的页面上输出这样的整个reports对象
[
{
"_id": "5775d396077082280df0fbb1",
"author": "57582911a2761f9c77f15528",

"picture": "",
"description": "",
"location": [

],
"latitude": 37.784495,
"longitude": -122.46596999999997,
"address": "4529 California St, San Francisco, CA 94118, USA",
"contact": "John Doe",
"type": "Financial",
"__v": 0,
"updated_at": "2016-07-01T02:21:10.259Z",
"created_at": "2016-07-01T02:21:10.237Z",
"tags": [
"tag1,tag2"
]
}
]
但是,如果我尝试循环遍历对象,如下所示它得到一个UNDEFINED作为我的报表对象的返回属性,我显然得到一个无限循环.
我尝试过循环的另一种变体,但我仍然不成功:
