node.js request multi line - node.js

Google analytics measurement protocol says to use multiple lines for their /batch endpoint:
https://developers.google.com/analytics/devguides/collection/protocol/v1/devguide#batch
POST /batch HTTP/1.1
Host: www.google-analytics.com
v=1&tid=UA-XXXXX-Y&cid=555&t=pageview&dp=%2Fhome
v=1&tid=UA-XXXXX-Y&cid=555&t=pageview&dp=%2Fabout
v=1&tid=UA-XXXXX-Y&cid=555&t=pageview&dp=%2Fcontact
How would I do something like that with node.js and request? Here's my current code for /collect
request.post(
'http://www.google-analytics.com/batch',
{ form: { v:1,tid:'UA-xxxxx-1',cid:event.queryStringParameters.cid,t:'event',ec:'xxx',ea:"xxx", el:"xxx", ev:"xxx", dr:'xxx'} },
function (error, response, body) {
done(null,'Check for GA event');
}
);

Combine each line in a single string, separated by "\n".
const request = require("request");
request({
url: "http://www.google-analytics.com/batch",
method: "post",
body: "v=1&t=pageview&tid=UA-XXXXXXXX-X&cid=555&dl=https%3A%2F%2Fmydomain.com%2Ftest&dt=Test\nv=1&t=pageview&tid=UA-XXXXXXXX-X&cid=554&dl=https%3A%2F%2Fmydomain.com%2Ftest2&dt=Test2"
}, function(error, response, body) {
if (error) { console.log(error); }
});
Your real-time report will show 2 active users on 2 different pages.

Node.js request module

I'm trying to use the request module to send post request to another service but the callback never fires. Here is what I'm doing right now:
request.post(
`http://localhost:3002/users/login`,
{
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({userDetails})
},
function (error, response, body) {
if (!error && response.statusCode == 200) {
const data = JSON.parse(body);
console.log(data);
} else {
console.log('Request has failed. Please make sure you are logged in');
res.status(401).send(body);
}
}
);
The callback function never fires. On the other hand, if I try to send this exact request with Postman, the server gets the request. What am I doing wrong?
Syntax error maybe? Try with:
request({
method: 'POST',
url: 'http://localhost:3002/users/login',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({userDetails})
},
function (error, response, body) {
// Now it should fire the callback.
console.log('okay');
});
Works like a charm on my side.
Edit: If it still doesn't work, my bet is that the cross-origin resource sharing is not enabled for the localhost:3002 server you're trying to access. Here's the easiest way to enable it.

Send unparsed data in a Node JS request

I want to send a POST request (for example, with the 'request' module), but I don't find a way of sending unparsed data*.
*unparsed data => copied directly from the Chrome dev tool. Something like: tipo_accion=3&filtro=descarga&fecha=actual
It would also do the trick some way of translating that string to JSON.
I've tried so far with...
var request = require('request');
request.post({ url: 'https://target.com/form/', form: 'tipo_accion=3&filtro=descarga&fecha=actual' },
function (error, response, body) {
console.log(body)
}
);
... but it didn't work.
Firstly you should understand the difference between the request methods post and get.
The structure that you want to send:
tipo_accion=3&filtro=descarga&fecha=actual is telling me that you want to use a get request. So the proper code for that will be something like:
request(
'https://target.com/form/&tipo_accion=3&filtro=descarga&fecha=actual',
function (error, response, body) {
console.log(body)
},
);
But if it is a post request then you should use the json format
request.post({
url: 'https://target.com/form/', form: {
tipo_accion: 3,
filtro: 'descarga',
fecha: 'actual'
},
function(error, response, body) {
console.log(body)
}
);
You can convert form_data to string format and it works for me you can try it :
const request = require('request-promise');
var j = request.jar()
var data_fom = `a=value_a&b=value_b&c=value_c`
request({
url:"https://target.com/form/",
jar:j,
method:"POST",
resolveWithFullResponse: true,
form:data_form
})

Send a File From Api Server to NodeJs to Browser

I have an API Server and NodeJs Server and when a file is requested NodeJs redirected the request to API Server
API Server Send the File as raw data to NodeJs
and Nodejs redirects the file to the browser
But when I checked the network data using wire shark the packet received at browser is not original as that from API Server (work in case of text files, but not in image, video, pdf, doc etc)
router.get('/GetCaseSupportDocument', function (req, res) {
var MyJsonData = {
DocId:parseInt(req.query.DocId) || 0
};
request({
url: 'http://somedomain/someurl', //URL to hit
method: 'POST',
json: MyJsonData
}, function (error, response, body) {
if (error) {
res.status(200).send('Failed');
} else {
res.status(200).send(body);
}
})
});
Can anyone tell why it changes between NodeJs to Browser?
Is there any better solution for this type of transmission?
Updated After finding solution . This works
router.get('/GetCaseSupportDocument', function (req, res) {
var MyJsonData = {
DocId:parseInt(req.query.DocId) || 0
};
request({
url: Url.CaseService + 'GetCaseSupportDocument', //URL to hit
method: 'POST',
json: MyJsonData
}).pipe(res);
})
There is a simple proxy using streams that you can try:
router.get('/GetCaseSupportDocument', function (req, res) {
var MyJsonData = {
DocId: parseInt(req.query.DocId) || 0
};
// updated the response
request({
url: 'http://somedomain/someurl', //URL to hit
method: 'POST',
json: MyJsonData
}).pipe(res);
});
More details with proxy-ing you can find on the request documentation https://github.com/request/request

Sending an API request with Nodejs

I've been trying to hit an API and get some data back from it (It's a free API not my own). So I've got my API token and I've had a look around and found that npm package request seems to be the best.
Within one of my routes I have,
request({
uri: "https://app.url-to-api:443/api/list-of-data",
method: "GET",
api_token: "my-api-token",
timeout: 10000,
followRedirect: true,
maxRedirects: 10
}, function(error, response, body) {
console.log(body);
});
So I'm getting "message":"Authorization has been denied for this request." back which is obviously because my API Token isn't getting passed through.
This might be a stupid question, but where do I actually put the API token to validate my request?
Thanks!
In request it would be something like this:
request.get('http://some.server.com/', {
'auth': {
'bearer': 'bearerToken'
}
});
More details on what you can do with request are in the docs.
You have to pass api tokens in request headers please see the documentation for request
var request = require('request');
var options = {
url: 'https://api.github.com/repos/request/request',
headers: {
'Access-Token': 'request'
}
};
function callback(error, response, body) {
if (!error && response.statusCode == 200) {
var info = JSON.parse(body);
console.log(info.stargazers_count + " Stars");
console.log(info.forks_count + " Forks");
}
}
request(options, callback);

How to view request sent from node.js to server?

Regarding to this question:
Transfer / pass cookies from one request to another in nodejs/protractor
I got another one. How could I view complete request (headers + body) which I am performing via nodejs?
Yes, you can ... You can access the complete request from the full response body - response.request
I have a generic full response structure illustrated below
IncomingMessage
ReadableState
headers(ResponseHeaders)
rawHeaders
request - //This is what you need
headers
body
body(Response Body)
You can access through code as shown below
var request = require("request");
var options = { method: 'POST',
url: 'http://1.1.1.1/login',
headers:
{ 'cache-control': 'no-cache',
'content-type': 'application/json' },
body: { email: 'junk#junk.com', password: 'junk#123' },
json: true };
request(options, function (error, response, body) {
if (error) throw new Error(error);
// This will give you complete request
console.log(response.request);
//This gives you the headers from Request
console.log(response.request.headers);
});
