AWS Lambda: Error: getaddrinfo ENOTFOUND

问题

here's the code in AWS Lambda function:

var https = require('https');
exports.handler = (event, context, callback) => {
    var params = {
        host: "bittrex.com",
        path: "/api/v1.1/public/getmarketsummaries"
    };
    var req = https.request(params, function(res) {
        var test = res.toString();
        console.log(JSON.parse(test));
        //console.log(JSON.parse(res.toString()));
    });
    req.end();
};

Error: getaddrinfo ENOTFOUND https://bittrex.com https://bittrex.com:443 at errnoException (dns.js:28:10) at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:76:26)

I am not able to figure, please help. Other solutions did not work.

I modified your code to work correctly in AWS Lambda Node.js 6.10. I set the Lambda timeout to be 60 seconds for testing.

The big change is adding "res.on('data', function(chunk) {}:" and "res.on('end', function() {}".

var https = require('https');
exports.handler = (event, context, callback) => {
    var params = {
        host: "bittrex.com",
        path: "/api/v1.1/public/getmarketsummaries"
    };
    var req = https.request(params, function(res) {
        let data = '';
        console.log('STATUS: ' + res.statusCode);
        res.setEncoding('utf8');
        res.on('data', function(chunk) {
            data += chunk;
        });
        res.on('end', function() {
            console.log("DONE");
            console.log(JSON.parse(data));
        });
    });
    req.end();
};

回答2:

Remove the https:// from the host. The require already says you're using https/SSL.

回答3:

The issue is with your security groups. Looks like your lambda doesn’t have access to resolve DNS. Check if you lambda sec groups have port 53 UDP and TCP enabled.
