I have this class written in javascript but I have difficulty in obtaining the result from the axios request, below my situation to better explain the problem:
i have a file called vtiger.js in the classes directory in the project root
vtiger.js
const axios = require('axios');
var md5 = require('md5');
var qs = require('qs');
const https = require('https');
class vTiger {
constructor() {
this.url = process.env.VTIGER_URL;
this.username = process.env.VTIGER_USERNAME;
this.password = process.env.VTIGER_PASSWORD;
}
async getchallengeTokenVtiger() {
var token;
var tokenmd5 = false;
var url = this.url + 'webservice.php?operation=getchallenge&username=' + this.username;
axios.get(url,
{
headers: {
"content-type": "application/x-www-form-urlencoded"
},
httpsAgent: new https.Agent(
{
rejectUnauthorized: false
})
}).then(response => {
if (response.data.success) {
token = response.data.result.token;
tokenmd5 = md5(token + this.password);
return tokenmd5;
}
});
}
}
module.exports = vTiger
then I have a file called api.js in the controllers folder with this content:
const http = require('http');
const axios = require('axios');
var qs = require('qs');
const vTiger = require('../classes/vtiger');
exports.welcome = (req, res, next) => {
const vtigerClass = new vTiger();
console.log(vtigerClass.getchallengeTokenVtiger())
res.status(200).json({
data: vtigerClass.getchallengeTokenVtiger()
});
}
from this file as an response I get:
{
"data": {}
}
while from the console.log(vtigerClass.getchallengeTokenVtiger()) line I get this:
Promise { undefined }
Where am I doing wrong?
Thanks
you probably don't want to use the .then in an async function. you should
const response = await axios.get(...)
if (response.data.success) {
token = response.data.result.token;
tokenmd5 = md5(token + this.password);
return tokenmd5;
}
else return null;
Or you can create a variable in your function called tokenmd5 i.e.
let tokenmd5 = ''
set its value in the .then, then return tokenmd5 at then end of your function NOT in the .then
THEN: for your console.log you want:
exports.welcome = async (req, res, next) => {
const vtigerClass = new vTiger();
console.log(await vtigerClass.getchallengeTokenVtiger())
res.status(200).json({
data: vtigerClass.getchallengeTokenVtiger()
});
}
