I am trying to develop a google cloud function that will make an external https GET request and return the response body to the client.
Flow:
exports.mockServer = (req, res) => {
'use strict';
var https = require('https');
var options = {
host: 'example.com',
path: '/path',
headers: {
'accept': 'application/json',
'X-API-Key': 'XXXX'
}
};
if (req.method == 'GET'){
https.get(options, function (res) {
var data = '';
res.on('data', function (chunk) {
data += chunk;
});
res.on('end', function () {
if (res.statusCode === 200) {
var res_body = JSON.parse(data);
var results = JSON.stringify(res_body.result)
console.log("results:"+results);
} else {
console.log('Status:', res.statusCode);
}
});
}).on('error', function (err) {
console.log('Error:', err);
});
} else {
console.log("Wrong Method");
}
res.end()
};I am able to successfully log the results with console.log("results:"+results); but I cannot figure out how to get it returned to the client. I am still new to this and am learning, so thank you so much in advance to any help!
Posting @YouthDev's solution as an answer:
Thanks to @DougStevenson and @Deko in the comments, I switched to an axios library and it works like a charm. Thank you to both for pointing me in the correct direction. Below is the working axios code.
exports.mockServer = (req, res) => {
const axios = require('axios').create({
baseURL: 'https://example.com'
});
return axios.get('/path',{ headers: {'accept': 'application/json','X-API-Key': 'XXXXXX'} })
.then(response => {
console.log(response.data);
return res.status(200).json({
message: response.data
})
})
.catch(err => {
return res.status(500).json({
error: err
})
})
};
