Я хотел бы отправить данные в мой NodeJS бэкэнд (Express framework), а затем создать событие в Календаре Google с помощью API Календаря Google.
Я получаю данные с помощью метода POST form express .Router ()
В этот момент, если я отправляю запрос с помощью Почтальона, я получаю сообщение об ошибке: «Произошла ошибка при обращении в службу календаря: Ошибка: Требуется вход в систему»
Мой вопрос заключается в том, как вызвать метод insertEvent () внутри тела метода post и передать данные, полученные от пользователя?
Аналогичная ситуация описана в этом сообщении Вставить событие в календарь Google nodejs но данные жестко закодированы.
Мой полный код:
var express = require('express');
var router = express.Router();
const fs = require('fs');
const readline = require('readline');
const {google} = require('googleapis');
const myEvents = [];
// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/calendar'];
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
const TOKEN_PATH = 'token.json';
// Load client secrets from a local file.
fs.readFile('credentials.json', (err, content) => {
if (err) return console.log('Error loading client secret file:', err);
// Authorize a client with credentials, then call the Google Calendar API.
authorize(JSON.parse(content), listEvents);
authorize(JSON.parse(content), insertEvents);
});
/**
* Create an OAuth2 client with the given credentials, and then execute the
* given callback function.
* @param {Object} credentials The authorization client credentials.
* @param {function} callback The callback to call with the authorized client.
*/
function authorize(credentials, callback) {
const {client_secret, client_id, redirect_uris} = credentials.installed;
const oAuth2Client = new google.auth.OAuth2(
client_id, client_secret, redirect_uris[0]);
// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, (err, token) => {
if (err) return getAccessToken(oAuth2Client, callback);
oAuth2Client.setCredentials(JSON.parse(token));
callback(oAuth2Client);
});
}
/**
* Get and store new token after prompting for user authorization, and then
* execute the given callback with the authorized OAuth2 client.
* @param {google.auth.OAuth2} oAuth2Client The OAuth2 client to get token for.
* @param {getEventsCallback} callback The callback for the authorized client.
*/
function getAccessToken(oAuth2Client, callback) {
const authUrl = oAuth2Client.generateAuthUrl({
access_type: 'offline',
scope: SCOPES,
});
console.log('Authorize this app by visiting this url:', authUrl);
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
});
rl.question('Enter the code from that page here: ', (code) => {
rl.close();
oAuth2Client.getToken(code, (err, token) => {
if (err) return console.error('Error retrieving access token', err);
oAuth2Client.setCredentials(token);
// Store the token to disk for later program executions
fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
if (err) return console.error(err);
console.log('Token stored to', TOKEN_PATH);
});
callback(oAuth2Client);
});
});
}

calendar.events.list({

singleEvents: true,
orderBy: 'startTime',
}, (err, res) => {
if (err) return console.log('The API returned an error: ' + err);
const events = res.data.items;
if (events.length) {
myEvents.push(events);

console.log('No upcoming events found.');
}
});
