Node.JS Invalid URI Error: GET Request using Query parameter

I am trying to do query to find a account using rest services of the target application name hexion.
When I am running it is giving Invalid uri error.
The url that I tested in postman is like below
https://ekaa-dev1.fa.us6.oraclecloud.com/crmRestApi/resources/11.13.18.05/accounts?q=OrganizationName = Hexion
and in postman I am getting response too.
But I feel somewhere in my code I am doing some syntax error but not able to find that
//nodejs v4.2.6
console.log("Hello, World!");
var Request = require("request");
var serviceUserName="msonawane#gmail.com";
var password="Welcome01";
var personalDataURL="https://ekaa-dev1.fa.us6.oraclecloud.com/crmRestApi/resources/11.13.18.05/accounts";
var option1 = {
uri: personalDataURL,
qs: {
q:{OrganizationName:"Hexion"}
},
headers: {
"Authorization" : auth,
"Content-Type": 'application/json',
"Accept":'application/json'
}
};
var auth = `Basic ` + new Buffer(serviceUserName+`:`+password).toString(`base64`);
Request.get(option1, { json: true },
(error, response, body) => {
console.log(response);
//console.log(response.url);
if (error) { return console.log(body,error); }
console.log(body.url);
console.log(body.explanation);
});
I expect it to return response after successful get
Please let me know error, I have changed the auth credentials so once you find anything to be corrected let me for the above code, I will try with right credentials and update you

request.get method expects first parameter as url, but you are passing options1 obj, it couldn't find url hence it is giving error "Invalid uri /".
You can append query parameter to url OR use querystring npm
var personalDataURL= "https://ekaa-dev1.fa.us6.oraclecloud.com/crmRestApi/resources/11.13.18.05/accounts?q=OrganizationName=Hexion"
request({
headers: {
"Authorization" : auth,
"Content-Type": 'application/json',
"Accept":'application/json'
},
uri: personalDataURL,
method: 'GET'
}, function (err, res, body) {
//it works!
});

Nodejs Auth0 read users with api not working (err: 400, msg: Bad HTTP authentication header format)

I'm trying to receive my users that are stored in Auth0. So, I tried using this website Auth0 management API docs with my API token and API domain. This works fine!
Then I tried to do the same in node js, but when I do that it returns an error. The error message is:
"statusCode":400,"error":"Bad Request","message":"Bad HTTP authentication header format","errorCode":"Bearer"
This is the code that i fount in the documentation
var request = require("request");
var options = { method: 'GET',
url: 'https://<api_url>/api/v2/users',
headers: { authorization: 'Bearer ACCESS_TOKEN' }
};
request(options, function (error, response, body) {
if (error) throw new Error(error);
console.log(body);
});
The only thing that is changed is that I deleted the query string and inserted my api_url and the same access token that I used on the Auth0 management API docs (which works). Am I missing something?

The code looks perfectly fine. I edited it with my hostname/access token as follows and it returned the users:
var request = require("request");
var token = 'eyJ0...'
var options = { method: 'GET',
url: 'https://tenant_name.auth0.com/api/v2/users',
headers: { authorization: 'Bearer ' + token }
};
request(options, function (error, response, body) {
if (error) throw new Error(error);
console.log(body);
});
The two things that might have gone wrong in your case are:
You didn't properly replace the ACCESS_TOKEN in the code.
The access token does not have the read:users permission. You can verify this by pasting the token in jwt.io and inspecting the payload.

Chunked base64 string, piece by piece using http nodejs

From my API(nodejs), I'm accessing a third-party API (using http) to download files.
The service returns a Base64 string, chopped into smaller pieces, to be able to handle larger files.
Is it possible to do multiple http-requests (loop ?) to the third-party service, send each piece in response, to the browser until there is no longer any response from the third-party service?
The reason i want to do this, is because I don't want to consume to much memory on the node server.
I will put the pieces back together in the browser.
Any suggestions on how to do this?
See my current code below.
var request = require('request');
router.post('/getfiledata', function(req, res) {
var fileid = req.body.fileid;
var token = req.headers.authorization;
getFileData(req, res, dbconfig, fileid, token, function(err, chunkOfFile) {
if (err) {
res.status(500).send({
status: 500,
message: err
});
return;
}
res.send(chunkOfFile);
});
});
function getFileData(req, res, dbconfig, fileid, token, next) {
var url ="http://*ip*/service/rest/getfiledata";
var reqbody = {
fileId: fileid
};
var options = {
url: url,
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': token
},
json: true,
body: reqbody
};
/*SOME LOOP HERE TO GET EACH CHUNK AND SEND TO BROWSER*/
request(options, function(err, resp, body) {
if (err) {
console.log(err);
next(err, undefined);
return;
} else {
next(undefined, body)
};
});
};

I think you need Socket.io to push chunks to the browser.
Server :
socket.send("chunk", chunkOfFile)
Client :
let fullString = ""
socket.on("chunk", chunkOfFile => fullString += chunkOfFile )
Something like that

The request library you are using allows for streaming of data from one source to another. Check out the documentation on github.
Here is an example from that page:
request
.get(source)
.on('response', function(response) {
console.log(response.statusCode) // 200
console.log(response.headers['content-type']) // 'image/png'
})
.pipe(request.put(destination))
You may choose to use the http module from Nodejs, as it implements the EventEmitter class too.

I ended up doing a recursive loop from the client. Sending http-requests to my API(node) until the response no longer returns any base64 data chunks.
Thank you guys!

Node JS How to POST image along with request data to another server/api

I am trying to POST an image from my Node JS app to another REST API. I have the image in Mongo DB (as binary array data) that is read by Node JS and then is supposed to be POSTed to another API.
The problem I face is how do I send request data along with the image? I have this raw data (that is in JSON format) that should be POSTed along with image:
{"data":{"client":"abc","address": "123"},"meta":{"owner": "yourself","host": "hostishere"}}
I am required to do this using the 'request' module. I can use 'multer' if that helps better. But, I am stuck on how do I send the above request data along with the image stream. Below is my current code. Could you please help me finish it?
var options = {
host: 'hostname.com',
port: 80,
path: '/api/content',
method: 'POST',
headers:{
'Content-Type' : 'multipart/form-data'
}
};
var request = http.request(options, function(response) {
var str = '';
var respTime ='';
response.on('data', function (chunk) {
str = str.concat(chunk);
});
response.on('end', () => {
console.log('No more data in response.');
});
setTimeout(function() {
res.send(JSON.stringify(
{
'imageURL': IMG_URL,
'imageId': IMG_ID,
'body': JSON.parse(str)
}
));
}, 1000);
});
request.on('error', (e) => {
console.error('**** problem with request: ', e);
});
request.write(image.IMG_STR); //image.IMG_STR is the binary array representation of the image.
request.end();
UPDATE: 06/06/2017
So, I happened to talk to the REST team that provides the end point and found out that the data should be sent in the following specific format. Below is a snapshot of the request that succeeded. Could someone help me with the Node code that I should use? I have tried form-data package but have been getting the same error:

if you have control over "the other API" too, you could include the image as base64 representation of the binary data in the post-body (and decode it on the API side)
answer to the update 06/06/2017:
according to the screenshot the API requires multipart/formdata.
such requests with the "request"-module are documented in https://github.com/request/request#multipartform-data-multipart-form-uploads
quick example (not tested):
var formData = {
Data: {data: {client: "abc" ...},
file: fs.createReadStream('testImage_2.jpg'),
};
request.post({url:'<YourUrl>', formData: formData}, function optionalCallback(err, httpResponse, body) {
if (err) {
return console.error('upload failed:', err);
}
console.log('Upload successful! Server responded with:', body);
});

If you add the body to your request with the JSON data, you should be able to send it:
var options = {
host: 'hostname.com',
port: 80,
path: '/api/content',
method: 'POST',
headers:{
'Content-Type' : 'multipart/form-data'
},
body: {
"data": {"client":"abc","address": "123"},
"meta":{"owner": "yourself","host": "hostishere"}
}
};
What I don't understand is why you have a setTimeout with res.send when there is no res variable defined anywhere.

Using request HTTP client library to post to FastSpring API

I am attempting to use request to POST to FastSpring's API for updating subscriptions for my customers. I am able to GET subscriptions without problem, but when it comes to POST, I cannot seem to get it to work.
Here is my code:
var options = {
method: 'POST',
url: 'https://api.fastspring.com/subscriptions',
headers: {
'Authorization': auth,
'User-Agent': 'request',
'Content-Type': 'application/json'
},
formData : {
'subscriptions': [
{
"subscription": subscriptionId,
"quantity": newQty,
"product": product,
"prorate": true
}
]
}
};
request.post(options, function (error, response, body) {
_logger.error('Fastspring API response: ' + JSON.stringify(response));
_logger.error('Fastspring API error: ' + JSON.stringify(error));
_logger.error('Fastspring API body: ' + JSON.stringify(body));
if (!error && response.statusCode === 200) {
res.status(200).send(JSON.parse(body));
} else {
_logger.error('Fastspring API Error: ' + error);
res.status(500).send({ 'error': error});
}
});
The result of attempting the POST results in the following error:
TypeError: source.on is not a function
I looked it up and saw that the reason why it was failing is that request cannot accept the formData I'm sending. Problem is that without it, I cannot POST to FastSpring's API (I get the error message "subscriptions not found." if I send anything else).
My question is this: Can I send my formData in any way that will be accepted by request? I've looked this issue up on the issues page of request and couldn't find a satisfactory answer.

Are you trying to pass some JSON data? Usually that kind of data are written in body not in formData.
Try something like this:
var myreq = request.post(...)
myreq.write(myJsonData);
myreq.end();
