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!
});

POST request from Node to another server with windows credentials

I am trying to send a post request to a service from my node server.
Node is running on http://localhost:3000. The method I am trying to reach is reachable through http://localhost:80/some/adress/business/layer/myMethod.
var options = {
host: 'localhost',
path: '/some/adress/business/layer/myMethod',
port: '80',
method: 'POST',
headers: {
'Content-type': 'application/json',
'Content-Length': data.length
}
};
var req = http.request(options, function (resu) {
console.log('statusCode: ' + res.statusCode)
resu.on('data', function (d) {
console.log(d);
});
resu.on('error', function (err) {
console.log(err);
});
resu.on('end', function () {
res.jsonp({ result: true });
res.end();
});
});
req.write("data");
req.end();
The request works fine, well more or less. I am getting a 401 status back. The question is: How can I send windows credentials from node to the named server running on localhost:80... ?

Without knowing the exact details of your setup, I can't be sure, but you probably need to use NTLM authentication. There are several libraries that do this for node. Take a look at this question. Hope this helps!

How to load JSON/API data using https.request and Node.JS

I'm trying to load weather data. I have front end code that was doing this perfectly but I need to move this to back end. I moved a library of my functions over to Node.JS. I was using $.getJSON but was told I should use https.request for the new version. Here's my code:
getTextWeatherUsingStationUsingRequest: function(theStation){
const http = require("http");
const https = require("https");
thePath = 'stations/' + theStation + '/observations/current';
// theURL = 'https://api.weather.gov/stations/' + theStation + '/observations/current';
function requestTheData(){
var options = {
protocol: "https:",
hostname: "https://api.weather.gov/",
path: thePath,
port: 80,
method: "GET"
};
var instaRequest = https.request(options);
instaRequest.on("response", function(res){
console.log(`STATUS: ${res.statusCode}`);
console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
res.setEncoding('utf8');
res.on('data', (chunk) => {
console.log(`BODY: ${chunk}`);
});
res.on('end', () => {
console.log('No more data in response.');
});
console.log("response");
console.log(res.statusCode);
console.log(res.statusMessage);
});
instaRequest.on('error', (e) => {
console.error(`problem with request: ${e.message}`);
});
instaRequest.end();
}
requestTheData();
I'm getting this error and can't figure out what's going on:
problem with request: getaddrinfo ENOTFOUND https://api.weather.gov/stations/ https://api.weather.gov/stations/:80

HTTPS generally uses port 443, so lets change that. Also, the API shows the hostname should be the raw URL and the path should be the remainder of the route (with a leading slash) similar to this:
thePath = '/stations/' + theStation + '/observations/current';
...
var options = {
hostname: "api.weather.gov",
path: thePath,
port: 443,
method: "GET"
};

Before even seeing any answers I got it working by:
protocol: "https:",
hostname: "api.weather.gov",
but then I was getting a STATUS:
403 Forbidden You don't have permission to access
"http://api.weather.gov/" on this server.
I seemed to remember that you are required to pass something in through headers so I added this under "method: "GET","
method: "GET",
headers: {
'Accept' : 'application/json',
'Content-Type': 'application/json',
'User-Agent' : 'MY-UA-STRING'
}
And, voila, now I'm getting JSON weather data. It didn't work until I added the 'User-Agent'. Do you guys know what this needs to be (and/or point me to a place that describes this)?

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.

How to make a POST request using CustomVision api with NodeJS

I'm trying attach an image using the bot emulator tool and sending this image off to the microsofts customvision api, the issue I'm having is that I get
{ Code: 'BadRequestImageFormat', Message: '' }
back from custom the custom vision api call.
I'm using the the request module from npm to handle the calls
// Receive messages from the user and respond by echoing each message back (prefixed with 'You said:')
var bot = new builder.UniversalBot(connector, function (session) {
session.send("Hello"); //session.message.text
// If there is an attachment
if (session.message.attachments.length > 0){
console.log(session.message.attachments[0])
request.post({
url: 'xxx',
encoding: null,
json: true,
headers: {
'Content-Type': 'application/octet-stream',
'Prediction-Key': 'xxx'
},
body: session.message.attachments[0]
}, function(error, response, body){
console.log(body);
});
}
});
I believe that I may be sending the wrong format through to custom vision however I have been unable to figure it out as of yet.

I replicated your issue and it looks like the problem is your 'Content-Type'. You're attempting to pass JSON in your request, but setting the content-type as octet-stream. See my modified code below:
var bot = new builder.UniversalBot(connector, function (session) {
session.send("Hello"); //session.message.text
// If there is an attachment
if (session.message.attachments.length > 0){
console.log(session.message.attachments[0])
request.post({
url: 'https://northeurope.api.cognitive.microsoft.com/vision/v1.0/analyze?visualFeatures',
encoding: null,
json: true,
headers: {
'Content-Type': 'application/json',
'Ocp-Apim-Subscription-Key': 'Your API Key...'
},
body: session.message.attachments[0]
},
function (err, response, body) {
if (err) return console.log(err)
console.log(body);
});
}
});
When I run this, I get the error InvalidImageUrl which is to be expected as it's looking for a content on localhost. You could get round this by exposing your localhost using Ngrok.
