如何从request.get获取正文中的信息到全局独家新闻

Question

Im totally new to JavaScript and I have a problem.

This is my code and it is working

'use strict';

const request = require("request")
const url = "https://something/v1/"

request.get(
  `${url}/tickers?symbols=tBTCUSD`,
    (error, response, body) => console.log(body)
    )

So this writes the expected data on the screen. So I have the data, I just dont want to put it on my screen, I want to process it. But how do I get that data out from the request.get function?

Something like this

'use strict';

const request = require("request")
const url = "https://something/v1/"

let global_answer

request.get(
  `${url}/tickers?symbols=tBTCUSD`,
    (error, response, body) => {
        console.log(body)
        global_answer = body;
})

my_function(global_answer);

Answer 1

Declare a variable in the global scope like this:

var debugBody;

request.get(
    `${url}/tickers?symbols=tBTCUSD`,
    (error, response, body) => {
        debugBody = body;
        console.log(body)
});

console.log(debugBody);

EDIT: Async function

This won't work because request.get works asynchronously, if you want to call a function, you should have the function defined globally and call it from inside the request.get callback:

var debugBody;

function logRequestBody(body){
    console.log(body);
}

request.get(
    `${url}/tickers?symbols=tBTCUSD`,
    (error, response, body) => {
        logRequestBody(body);
});

The code will work that way.

Answer 2

something more like this:

'use strict';

const request = require("request");
const url = "${url}/tickers?symbols=tBTCUSD";

request.get(url, (error, response, body) => {
  console.log(body);
  my_function(body);
});
