Axios

I have used this request for a http proxy to access https server

axios.get(
    'http://localhost:9200', 
    {
        httpsAgent: new HttpsProxyAgent({
            keepAlive: true,
            keepAliveMsecs: 1000,
            maxSockets: 256,
            maxFreeSockets: 256,
            proxy: 'http://localhost:8080'
        })
    }
)
.then(
    res => console.log('https response : ',res.data)
)
.catch(
    e => console.log('test error : ',e)
)
.finally(
    () => console.log('httpbin test completed')

);
