我正在尝试从API获取JSON并将其存储到MongoDB数据库中。显然,它不起作用。我的应用程序似乎在我尝试将数据保存到数据库时停滞不前。请建议如何解决。
这是我的代码:
var express = require('express');
var router = express.Router();
var http = require('http');
var mongo = require('mongoskin');
var db = mongo.db("mongodb://localhost:27017/zak", {native_parser : true});
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
var site = 'http://www.vsechnyzakazky.cz/api/v1/zakazka/?format=json&limit=2';
function getData(cb) {
http.get(site, function(res) {
// explicitly treat incoming data as utf8 (avoids issues with multi-byte chars)
res.setEncoding('utf8');
// incrementally capture the incoming response body
var body = '';
res.on('data', function(d) {
body += d;
});
// do whatever we want with the response once it's done
res.on('end', function() {
try {
var parsed = JSON.parse(body);
} catch (err) {
console.error('Unable to parse response as JSON', err);
return cb(err);
}
// pass the relevant data back to the callback
cb(
parsed.objects
);
});
}).on('error', function(err) {
// handle errors with the request itself
console.error('Error with the request:', err.message);
cb(err);
});
}
function writeData (data, allGood){
// couple of visual checks if all looking good before writing to db
console.log('writing');
console.log(typeof data);
console.log(data);
db.collection('zakazky').save(data, function(error, record){
if (error) throw error;
console.log("data saved");
});
}
function allGood(){console.log('all done');}
getData(writeData);
// ---------------------
module.exports = router;
