How to return two variables from ClientRequest? - http

Question

I made http request (Class: ClientRequest) and I need to return two variables from my "login method" via promise.
function login(name, pass,server) {
return new Promise((resolve, reject) => {
const request = net.request({
method: 'GET',
url: server+'/names.nsf?Login&Username=' + name + '&Password=' + pass,
useSessionCookies: true,
redirect: 'follow'
}
)
var first
var second
///first
request.on('response', (response) => {
...
first = response.statusCode
})
///second
request.on('redirect', (statusCode, method, redirectUrl) => {
...
second = redirectUrl
})
resolve([first, second])
request.end()
});
}
And I am using it in this way:
ipcMain.on('loginbackend', async (event, arg) => {
try {
const loginInfo = await login(arg.name, arg.pass,arg.server)
event.returnValue = loginInfo
}
catch (error) {
console.error('ERROR:');
console.error(error);
}
});
I can return var putting resolve() into request.on method, but I need return both vars from both request.on. It seems request.on is asynchronize, how can I do that?

You should return your variables when end event of response is emited
function login(name, pass, server) {
return new Promise((resolve, reject) => {
const request = net.request({
method: 'GET',
url: server + '/names.nsf?Login&Username=' + name + '&Password=' + pass,
useSessionCookies: true,
redirect: 'follow'
}
)
var first
var second
///first
request.on('response', (response) => {
...
first = response.statusCode
response.on('end', () => {
resolve([first, second]);
});
})
///second
request.on('redirect', (statusCode, method, redirectUrl) => {
...
second = redirectUrl
})
request.end()
});
}
