i am trying to run this code but it keeps giving me a ReferenceError: json is not defined. Am I putting the JSON parse in the wrong position or something? This is basically a scraper, so it returns a lot of information and that is why it needs to be parsed
const request = require('request');
const options = {
method: 'GET',
url: 'https://siteToParse.com/api/v1/timelines/public',
json: true,
};
obj = JSON.parse(json);
request(options, function(err, res, body) {
if (err) {
console.dir(err);
return;
}
console.log('headers', res.headers);
console.log('status code', res.statusCode);
console.log(body);
});
EDIT: I changed it to obj = JSON.parse(JSON.stringify(body)) and it didn't throw any errors at all. But it's still returned a lot of information, and I'm not sure what to do with it?
I think you should rewrite it as this:
const request = require('request');
const options = {
method: 'GET',
url: 'https://siteToParse.com/api/v1/timelines/public',
json: true,
};
request(options, function(err, res, body) {
if (err) {
console.dir(err);
return;
}
console.log('headers', res.headers);
console.log('status code', res.statusCode);
console.log(body);
obj = JSON.parse(body); //---------------------> call to parse should come here
console.log(obj);
});

I run the code below and it brings back a lot of data but I only want to return the account name, which is listed as 'acct' in the data. To give you a clear idea of the data, I've copied/pasted some of it here, and blanked out any identifying info in order to protect people's privacy http://txt.do/11pf6
tried console logging different parameters but it didn't work
const request = require('request');
const options = {
method: 'GET',
url: 'https://SiteImScraping.com/api/v1/timelines/public',
json: true,
};
request(options, function(err, res, body) {
if (err) {
console.dir(err);
return;
}
console.log('headers', res.headers);
console.log('status code', res.statusCode);
console.log(body);
obj = JSON.parse(JSON.stringify(body));
for(i in obj) {
console.log(i['account']);
}
console.log(obj);
});
EDIT: I changed the code to the following, and now it only returns the parameter I need from the JSON data. Thanks for the suggestions!
const request = require('request');
const options = {
method: 'GET',
url: 'https://siteParsed.com/api/v1/timelines/public',
json: true,
};
request(options, function(err, res, body) {
if (err) {
console.dir(err);
return;
}
obj = JSON.parse(JSON.stringify(body));
for(i in obj) {
console.log(obj[i].account.acct);
}
});
Simply access it as if it was an object:
obj.account.acct
Pro tip, use something like http://jsonviewer.stack.hu/ to more easily view JSON
change
obj = JSON.parse(JSON.stringify(body));
to
obj = JSON.parse(body);
then you can be able to traverse through the data like;
obj.level1.level2.level3
I am using node js and making a call to spotify API and receive the response in body object, as shown in below code:
var options = {
url: 'https://api.spotify.com/v1/me',
headers: { 'Authorization': 'Bearer ' + access_token },
json: true
};
request.get(options, function(error, res, body) {
console.log(body)
});
This gives me output:
But now when I try to access the body object outside the function I get undefined. I think the problem is that I am making an asynchronous call and so before the response is received the statements where I make use of body variable outside function are executed. But I am a bit confused about how to get to the solution.
Any help is appreciated
Edit:
request.get(options, function(error, res, body) {
console.log(body)
response.render('user_account.html', {
data: body
})
});
And it gives the output:
Use promise.
You can try following:
const apiCall = () => {
return new Promise((resolve, reject) => {
var options = {
url: 'https://api.spotify.com/v1/me',
headers: { 'Authorization': 'Bearer ' + access_token },
json: true
};
request.get(options, function(error, res, body) {
if(error) reject(error);
console.log(body);
resolve(body);
});
});
}
apiCall().then((body) => {
// do your things here
})
.catch((err) => console.log(err));
after a post request from an ajax call in angularjs, i want to send the request params from angularjs to an external api. I get all params i want. But I don't know, how i can make a new post request to the api, inside my nodejs url. I need this step to nodejs.
This is my Code
router.post({
url: '/user/:id/sw'
}, (req, res, next) => {
var userId = req.pramas.id;
var firstName = req.pramas.firstName;
var lastName = req.pramas.lastName;
var data = 'test';
res.send(200, data);
});
I found some solutions like this on: (just example code)
request({
uri: 'http://www.giantbomb.com/api/search',
qs: {
api_key: '123456',
query: 'World of Warcraft: Legion'
},
function(error, response, body) {
if (!error && response.statusCode === 200) {
console.log(body);
res.json(body);
} else {
res.json(error);
}
}
});
but this doesn't work. How I can make a new Post Request with the req.params to an external api? Also i need a Response from the api..
Thanks for help and Ideas :)
Its req.params not req.pramas
Try this
var request = require('request');
router.post({
url: '/user/:userId/shopware'
}, (req, res, next) => {
var params = req.params;
request.get({
uri: 'http://www.giantbomb.com/api/search',
qs: params // Send data which is require
}, function (error, response, body) {
console.log(body);
});
});
Try this,
const request = require('request-promise')
const options = {
method: 'POST',
uri: 'http://localhost.com/test-url',
body: {
foo: 'bar'
},
json: true
// JSON stringifies the body automatically
};
request(options)
.then(function (response) {
// Handle the response
})
.catch(function (err) {
// Deal with the error
})
var request = require("request");
exports.checkstatus = async (req, res) => { //this is function line you can remove it
try {
var options = {
method: 'POST',
url: 'https://mydoamin/api/order/status',
headers:
{
signature: '3WHwQeBHlzOZiEpK4yN8CD',
'Content-Type': 'application/json'
},
body:
{
NAME: 'Vedant',
ORDERID: 'ORDER_ID1596134490073',
},
json: true
};
request(options, function (error, response, body) {
if (error) throw new Error(error);
console.log(body); //get your response here
});
} catch (error) {
return fail(res, error.message);
}
};

How do I return the response from an asynchronous call?

Closed 5 years ago.
[EDIT]
I figured it out. The code ends up like this:
//getTrelloJSON.js
var request = require('request');
'use strict';
function getProjJSON(requestURL, callback){
request.get({
url: requestURL,
json: true,
headers: {'User-Agent': 'request'}
}, (err, res, data) => {
if (err) {
console.log('Error:', err);
} else if (res.statusCode !== 200) {
console.log('Status:', res.statusCode);
} else {
callback(data);
}
});
}
module.exports.getProjJSON = getProjJSON;
And
//showData.js
var getJSON = require('./getTrelloJSON');
getJSON.getProjJSON('https://trello.com/b/saDpzgbw/ld40-gem-sorceress.json', (result) => {
var lists = result.lists;
console.log(lists);
});
I run node showData.js and it gets the json and then I can manipulate it as needed. I printed just to show it works.
[EDIT END]
I'm new to node.js and I am facing a noob problem.
This code is supposed to request a JSON from a public trello board and return an object with a section of trello's json (lists section).
The first console.log() does not work but the second does.
How do I make it wait for the completion of getProjJSON() before printing it?
var request = require('request');
'use strict';
//it fails
console.log(getProjJSON('https://trello.com/b/saDpzgbw/ld40-gem-sorceress.json'));
function getProjJSON(requestURL){
request.get({
url: requestURL,
json: true,
headers: {'User-Agent': 'request'}
}, (err, res, data) => {
if (err) {
console.log('Error:', err);
} else if (res.statusCode !== 200) {
console.log('Status:', res.statusCode);
} else {
//it works
console.log(data.lists);
return data.lists;
}
});
}
Node.js is all about callbacks.
And here you just not register the callbacks for data.
var client = require('http');
var options = {
hostname: 'host.tld',
path: '/{uri}',
method: 'GET', //POST,PUT,DELETE etc
port: 80,
headers: {} //
};
//handle request;
pRequest = client.request(options, function(response){
console.log("Code: "+response.statusCode+ "\n Headers: "+response.headers);
response.on('data', function (chunk) {
console.log(chunk);
});
response.on('end',function(){
console.log("\nResponse ended\n");
});
response.on('error', function(err){
console.log("Error Occurred: "+err.message);
});
});
or here is a full example, hope this solve your problem
const postData = querystring.stringify({
'msg' : 'Hello World!'
});
const options = {
hostname: 'www.google.com',
port: 80,
path: '/upload',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': Buffer.byteLength(postData)
}
};
const req = http.request(options, (res) => {
console.log(`res_code: ${res.statusCode}`);
console.log(`res_header: ${JSON.stringify(res.headers)}`);
res.setEncoding('utf8');
res.on('data', (chunk) => {
console.log(`res_data: ${chunk}`);
});
res.on('end', () => {
console.log('end of response');
});
});
req.on('error', (e) => {
console.error(`response error ${e.message}`);
});
//write back
req.write(postData);
req.end();
I want to get use this rest api with authentication. I'm trying including header but not getting any response. it is throwing an output which it generally throw when there is no authentication. can anyone suggest me some solutions. below is my code
var http = require('http');
var optionsget = {
host : 'localhost', // here only the domain name
port : 1234,
path:'/api/rest/xyz',
headers: {
'Authorization': 'Basic ' + new Buffer('abc'+ ':' + '1234').toString('base64')
} ,
method : 'GET' // do GET
};
console.info('Options prepared:');
console.info(optionsget);
console.info('Do the GET call');
var reqGet = http.request(optionsget, function(res) {
console.log("statusCode: ", res.statusCode);
res.on('data', function(d) {
console.info('GET result:\n');
process.stdout.write(d);
console.info('\n\nCall completed');
});
});
reqGet.end();
reqGet.on('error', function(e) {
console.error(e);
});
The request module will make your life easier. It now includes a Basic Auth as an option so you don't have build the Header yourself.
var request = require('request')
var username = 'fooUsername'
var password = 'fooPassword'
var options = {
url: 'http://localhost:1234/api/res/xyz',
auth: {
user: username,
password: password
}
}
request(options, function (err, res, body) {
if (err) {
console.dir(err)
return
}
console.dir('headers', res.headers)
console.dir('status code', res.statusCode)
console.dir(body)
})
To install request execute npm install -S request
In your comment you ask, "Is there any way that the JSOn I'm getting in the command prompt will come in the UI either by javascript or by Jquery or by any means."
Hey, just return the body to your client:
exports.requestExample = function(req,res){
request(options, function (err, resp, body) {
if (err) {
console.dir(err)
return;
}
// parse method is optional
return res.send(200, JSON.parse(body));
});
};
