I'm fumbling my way through node.js with massive help from people on here and I'm struggling getting the body of a GET request into a variable.
Here's the code so far:
var speechOutput;
var myCallback = function(data) {
console.log('got data: '+data);
speechOutput = data;
};
var usingItNow = function(callback) {
var http = require('http');
var url = 'http://services.groupkt.com/country/get/iso2code/IN';
var req = http.get(url, (res) => {
var body = "";
res.on("data", (chunk) => {
body += chunk;
});
res.on("end", () => {
var result = JSON.parse(body);
callback(result);
});
}).on('error', function(e){
console.log("Got an error: ", e);
});
};
usingItNow(myCallback);
I'm using examples from other posts to try and get the body of the GET request into the speechOutput variable but it is coming out as undefined.
Ultimately I want the RestResponse.result.name in speechOutput, but I thought I would take this one step at a time. Can anyone offer any pointers?
Further to this, I have tried the following, which still came back undefined - maybe there is a bigger issue with the code? It doesn't even seem to be getting to the parse.
res.on("end", () => {
// var result = JSON.parse(body);
callback('result');
});
putting the line callback('result');
before the line var req = http.get(url, (res) => {
returns 'result' but anything else is either undefined or causes an error.
