rest-hapi standalone endpoint not returning handler results - rest

Forgive me if it's a silly question, but the last time I coded in javascript was almost 20 years ago... I'm re-learning javascript these weeks and I'm not sure I got it all.
I'm using hapi with rest-hapi and want to add some standalone endpoints, basically translating the backend portion of this Autodesk tutorial form express.
I'm using the basic rest-hapi example main script, and tried to add a route with the following code:
//api/forge.js
module.exports = function(server, mongoose, logger) {
const Axios = require('axios')
const querystring = require('querystring')
const Boom = require('boom')
const FORGE_CLIENT_ID = process.env.FORGE_CLIENT_ID
const FORGE_CLIENT_SECRET = process.env.FORGE_CLIENT_SECRET
const AUTH_URL = 'https://developer.api.autodesk.com/authentication/v1/authenticate'
const oauthPublicHandler = async(request, h) => {
const Log = logger.bind('User Token')
try {
const response = await Axios({
method: 'POST',
url: AUTH_URL,
headers: {
'content-type': 'application/x-www-form-urlencoded',
},
data: querystring.stringify({
client_id: FORGE_CLIENT_ID,
client_secret: FORGE_CLIENT_SECRET,
grant_type: 'client_credentials',
scope: 'viewables:read'
})
})
Log.note('Forge access token retrieved: ' + response.data.access_token)
return h.response(response.data).code(200)
} catch(err) {
if (!err.isBoom){
Log.error(err)
throw Boom.badImplementation(err)
} else {
throw err
}
}
}
server.route({
method: 'GET',
path: '/api/forge/oauth/public',
options: {
handler: oauthPublicHandler,
tags: [ 'api' ],
plugins: {
'hapi-swagger': {}
}
}
})
}
The code works and I can display the access_token in nodejs console, but swagger doesn't get the response:
At first I thought that an async function cannot be used as handler, but my hapi version is 17.4.0, and it supports async handlers.
What am I doing wrong?

It turns out it was an easy fix: I just needed to specify the Hapi server hostname in my main script!
The problem was with CORS, since Hapi used my machine name instead of localhost. Using
let server = Hapi.Server({
port: 8080,
host: 'localhost'
})
solved my problem.

axios POST get 400

This is driving me crazy!
Exactly the same POST request works fine in Insomina per screenshot below:
The only header Insomina has is: Content-Type: application/json.
Now, the same request in code (I even copied the code generated from Insomnia for axios) via axios in Typescript:
const saveReqConfig: AxiosRequestConfig = {
method: 'POST',
url: 'THE SAME URL USED IN Insomina',
timeout: 3000,
data: {
name: `TestName`,
uri: `TestURI`,
statusCode: '200',
simulatedLatency: '0',
contentType: "application/json",
tags: '',
response: 'testing...',
type: 'VA',
},
headers: {
'Content-Type': 'application/json',
}
}
const normalAxios = axios.create();
const test = await normalAxios.request(saveReqConfig);
Don't understand why I am getting AxiosError: Request failed with status code 400 from code but the same request works fine in Insomina.
I think you did not set the headers correctly or you may not have setup the .create() properly.
Something like this:
const instance = axios.create({
url: '/post',
baseURL: 'https://httpbin.org',
method: 'POST',
timeout: 1000,
headers: {
Content-Type: 'application/json' // <- set your headers
}
});
let res = await instance.request({ // <- pass the data here
data: { // This should be whatever you want to post to this url. I just copied what you had.
name: `TestName`,
uri: `TestURI`,
statusCode: '200',
simulatedLatency: '0',
tags: '',
response: 'testing...',
type: 'VA',
}
});
Are you sure you need to use the .create() factory? The normal post like this might suite your needs better?
const data= { title: 'Axios POST Request Example' };
const headers = {
Content-Type: 'application/json'
};
axios.post('url', data, { headers }).then(response => console.log(response.data.title);
Posting here in case it helps someone.
It turned out that I couldn't post the request programmatically is because of lack of a TLS certificate. I didn't know that Insomnia has the option to disable the TLS and that's why it works in Insomnia.
To disable TLS (Do NOT do this in production!) from node with axios, create an instance of axios with a https agent setting rejectedUnauthorized to false e.g.
const instance = axios.create({
httpsAgent: new https.Agent({
rejectedUnauthorized: false
})
});
Also, set the environment variable as:
process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

Cannot read property 'Authorization' of undefined with Nuxt Auth & Axios

I have been using nuxt/auth-next and axios modules with nuxt project since last 3-4 months, everything was working fine since yesterday but now whenever I try to send axios request to public APIs without passing Authorization in headers, I get this error
Cannot read property 'Authorization' of undefined with Nuxt Auth & Axios
Attached is a screenshot of the page
below is my code in index.js store file
export const actions = {
async nuxtServerInit({ commit }, context) {
// Public profile
if (context.route.params && context.route.params.subdomain) {
context.$axios.onRequest((config) => {
config.progress = false
})
let { data } = await context.$axios.get(
`users/get_user_data_using_subdomain/${context.route.params.subdomain}`,
{
headers: {
'Content-Type': 'multipart/form-data',
},
}
)
await context.store.dispatch('artists/setPublicProfile', data.user_data)
}
},
}
This happend to me to when I was using context.app.$axios instead of context.$axios within a injection
Nuxt server is looking for config.headers.common.Authorization.
The example below is a quick win for you:
let { data } = await context.$axios.get(
`users/get_user_data_using_subdomain/${context.route.params.subdomain}`,
{
headers: {
common: null, // or something like this: context.$axios.defaults.headers?.common
'Content-Type': 'multipart/form-data',
},
}
)

How to create users using external API in owncloud

My application creates owncloud users using external APIs.
I tried with get owncloud version using external API. Below is the code I used:
$.ajax({
type: 'GET',
url: 'http://localhost/owncloud/index.php/apps/news/api/2.0/version',
contentType: 'application/json',
success: function (response) {
// handle success
},
error: function () {
// handle errors
},
beforeSend: function (xhr) {
var username = 'admin';
var password = 'admin';
var auth = btoa(username + ':' + password);
xhr.setRequestHeader('Authorization', 'Basic ' + auth);
}
});
The above code didn't work.
How to achieve this?
Thanks in advance.
The code you have put is right.
You could as well test if your api is returning the data using something like postman or chrome rest client.
then(function(response) {
$.ajax({
url: url,
type: "POST",
dataType: "json",
contentType: "application/json",
data: JSON.stringify(data),
})
.done(function(res) {
swal("Deleted!", "Your ListJds has been deleted.", "success");
})
.error(function(res) {
res;
swal("Delete Failure!", "Please Try Again.", "error");
});
})

ember-simple-auth facebook authenticator

Trying to hook up facebook authentication for my app. I've got the backend working correctly but my authenticator (I think this is the problem) is always returning undefined.
Copying the example from from ember-simple-auth the console log on line 23 is never called, making me think something else the issue?
import Ember from 'ember';
import Torii from 'ember-simple-auth/authenticators/torii';
const {inject: {service}} = Ember;
export default Torii.extend({
torii: service(),
ajax: service(),
authenticate() {
const ajax = this.get('ajax');
return this._super(...arguments).then((data) => {
return ajax.request('http://localhost:8080/api/login', {
type: 'POST',
dataType: 'application/json',
data: {
'grant_type': 'facebook_auth_code',
'auth_code': data.authorizationCode
}
}).then((response) => {
console.log("CALLED!");
return {
access_token: response,
provider: data.provider
};
});
});
}
});
The response from the server is the access_token from facebook;
How can I better debug/solve what's going on here?
The problem was actually a simple error with the dataType used. It should be dataType: 'json' not dataType: 'application/json'

How to make remote REST call inside Node.js? any CURL?

In Node.js, other than using child process to make CURL call, is there a way to make CURL call to remote server REST API and get the return data?
I also need to set up the request header to the remote REST call, and also query string as well in GET (or POST).
I find this one: http://blog.nodejitsu.com/jsdom-jquery-in-5-lines-on-nodejs
but it doesn't show any way to POST query string.
Look at http.request
var options = {
host: url,
port: 80,
path: '/resource?id=foo&bar=baz',
method: 'POST'
};
http.request(options, function(res) {
console.log('STATUS: ' + res.statusCode);
console.log('HEADERS: ' + JSON.stringify(res.headers));
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('BODY: ' + chunk);
});
}).end();
How about using Request — Simplified HTTP client.
Edit February 2020: Request has been deprecated so you probably shouldn't use it any more.
Here's a GET:
var request = require('request');
request('http://www.google.com', function (error, response, body) {
if (!error && response.statusCode === 200) {
console.log(body) // Print the google web page.
}
})
OP also wanted a POST:
request.post('http://service.com/upload', {form:{key:'value'}})
I use node-fetch because it uses the familiar (if you are a web developer) fetch() API. fetch() is the new way to make arbitrary HTTP requests from the browser.
Yes I know this is a node js question, but don't we want to reduce the number of API's developers have to memorize and understand, and improve re-useability of our javascript code? Fetch is a standard so how about we converge on that?
The other nice thing about fetch() is that it returns a javascript Promise, so you can write async code like this:
let fetch = require('node-fetch');
fetch('http://localhost', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: '{}'
}).then(response => {
return response.json();
}).catch(err => {console.log(err);});
Fetch superseeds XMLHTTPRequest. Here's some more info.
Look at http://isolasoftware.it/2012/05/28/call-rest-api-with-node-js/
var https = require('https');

Axios
An example (axios_example.js) using Axios in Node.js:
const axios = require('axios');
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;
app.get('/search', function(req, res) {
let query = req.query.queryStr;
let url = `https://your.service.org?query=${query}`;
axios({
method:'get',
url,
auth: {
username: 'the_username',
password: 'the_password'
}
})
.then(function (response) {
res.send(JSON.stringify(response.data));
})
.catch(function (error) {
console.log(error);
});
});
var server = app.listen(port);
Be sure in your project directory you do:
npm init
npm install express
npm install axios
node axios_example.js
You can then test the Node.js REST API using your browser at: http://localhost:5000/search?queryStr=xxxxxxxxx
Similarly you can do post, such as:
axios({
method: 'post',
url: 'https://your.service.org/user/12345',
data: {
firstName: 'Fred',
lastName: 'Flintstone'
}
});
SuperAgent
Similarly you can use SuperAgent.
superagent.get('https://your.service.org?query=xxxx')
.end((err, response) => {
if (err) { return console.log(err); }
res.send(JSON.stringify(response.body));
});
And if you want to do basic authentication:
superagent.get('https://your.service.org?query=xxxx')
.auth('the_username', 'the_password')
.end((err, response) => {
if (err) { return console.log(err); }
res.send(JSON.stringify(response.body));
});
Ref:

I have been using restler for making webservices call, works like charm and is pretty neat.
To use latest Async/Await features
https://www.npmjs.com/package/request-promise-native
npm install --save request
npm install --save request-promise-native
//code
async function getData (){
try{
var rp = require ('request-promise-native');
var options = {
uri:'https://reqres.in/api/users/2',
json:true
};
var response = await rp(options);
return response;
}catch(error){
throw error;
}
}
try{
console.log(getData());
}catch(error){
console.log(error);
}
Warning: As of Feb 11th 2020, request is fully deprecated.
One another example - you need to install request module for that
var request = require('request');
function get_trustyou(trust_you_id, callback) {
var options = {
uri : 'https://api.trustyou.com/hotels/'+trust_you_id+'/seal.json',
method : 'GET'
};
var res = '';
request(options, function (error, response, body) {
if (!error && response.statusCode == 200) {
res = body;
}
else {
res = 'Not Found';
}
callback(res);
});
}
get_trustyou("674fa44c-1fbd-4275-aa72-a20f262372cd", function(resp){
console.log(resp);
});
const http = require('http');
const url = process.argv[2];
http.get(url, function(response) {
let finalData = "";
response.on("data", function (data) {
finalData += data.toString();
});
response.on("end", function() {
console.log(finalData.length);
console.log(finalData.toString());
});
});
I didn't find any with cURL so I wrote a wrapper around node-libcurl and can be found at https://www.npmjs.com/package/vps-rest-client.
To make a POST is like so:
var host = 'https://api.budgetvm.com/v2/dns/record';
var key = 'some___key';
var domain_id = 'some___id';
var rest = require('vps-rest-client');
var client = rest.createClient(key, {
verbose: false
});
var post = {
domain: domain_id,
record: 'test.example.net',
type: 'A',
content: '111.111.111.111'
};
client.post(host, post).then(function(resp) {
console.info(resp);
if (resp.success === true) {
// some action
}
client.close();
}).catch((err) => console.info(err));
If you have Node.js 4.4+, take a look at reqclient, it allows you to make calls and log the requests in cURL style, so you can easily check and reproduce the calls outside the application.
Returns Promise objects instead of pass simple callbacks, so you can handle the result in a more "fashion" way, chain the result easily, and handle errors in a standard way. Also removes a lot of boilerplate configurations on each request: base URL, time out, content type format, default headers, parameters and query binding in the URL, and basic cache features.
This is an example of how to initialize it, make a call and log the operation with curl style:
var RequestClient = require("reqclient").RequestClient;
var client = new RequestClient({
baseUrl:"http://baseurl.com/api/", debugRequest:true, debugResponse:true});
client.post("client/orders", {"client": 1234, "ref_id": "A987"},{"x-token": "AFF01XX"});
This will log in the console...
[Requesting client/orders]-> -X POST http://baseurl.com/api/client/orders -d '{"client": 1234, "ref_id": "A987"}' -H '{"x-token": "AFF01XX"}' -H Content-Type:application/json
And when the response is returned ...
[Response client/orders]<- Status 200 - {"orderId": 1320934}
This is an example of how to handle the response with the promise object:
client.get("reports/clients")
.then(function(response) {
// Do something with the result
}).catch(console.error); // In case of error ...
Of course, it can be installed with: npm install reqclient.
You can use curlrequest to easily set what time of request you want to do... you can even set headers in the options to "fake" a browser call.
Warning: As of Feb 11th 2020, request is fully deprecated.
If you implement with form-data, for more info (https://tanaikech.github.io/2017/07/27/multipart-post-request-using-node.js):
var fs = require('fs');
var request = require('request');
request.post({
url: 'https://slack.com/api/files.upload',
formData: {
file: fs.createReadStream('sample.zip'),
token: '### access token ###',
filetype: 'zip',
filename: 'samplefilename',
channels: 'sample',
title: 'sampletitle',
},
}, function (error, response, body) {
console.log(body);
});
I found superagent to be really useful,
it is very simple
for example
const superagent=require('superagent')
superagent
.get('google.com')
.set('Authorization','Authorization object')
.set('Accept','application/json')
Update from 2022:
from node.js version v18 on you can use the globally available fetch API (see https://nodejs.org/en/blog/announcements/v18-release-announce/)
There is also an example usage included on their announcement page:
const res = await fetch('https://nodejs.org/api/documentation.json');
if (res.ok) {
const data = await res.json();
console.log(data);
}
