Question

For some reason, every 25000 MS (25 seconds), my ListLabels are being printed out twice. These duplicates are created exactly every 25 seconds. My code is below:

This is my main JS file, it's using modules such as express, as well as some of my own modules.

var express = require('express');
var app = express();
var fs = require('fs');
var getnewtoken = require('./auth.js');
var getauth = require('./getauth.js');
var getnewauth = require('./getnewauth.js');
var SCOPES = ['https://mail.google.com/'];
var google = require('googleapis');
var googleAuth = require('google-auth-library');

// getnewtoken(function (auth) { NEW ACCESS TOKEN
// listLabels(auth);
// });


listLabels();

    function startproccess(token) {
            getauth(token, function (auth) {
                setInterval( function (){
                    listLabels(auth);
                }, 25000)
            });
    }

function listLabels(auth) {
    if(typeof auth === 'undefined'){ // First run, no auth key found
        getnewtoken( function (token) {
            startproccess(token);
        });
        console.log('auth not valid, going to startproccess');
    }
        var gmail = google.gmail('v1');
        gmail.users.labels.list({
                auth: auth,
                userId: 'me@email.com',
        }, function(err, response) {
                if (err) { // API KEY NO LONGER VALID
                        console.log('The API returned an error: ' + err);
                        // Get new access token
                        getnewtoken( function (token) {
                            startproccess(token);
                            console.log("New token added");
                            return;
                        });
                        return;
                }
                var labels = response.labels;
                if (labels.length == 0) {
                        console.log('No labels found.');
                } else {
                        console.log('Labels:');
                        for (var i = 0; i < labels.length; i++) {
                                var label = labels[i];
                                console.log('- %s', label.name);
                        }
                }
        });
}


app.listen(3000, function(){
    //console.log("Listening on port 3000");
});

一次

auth==='undefined'

你需要打破这个功能，否则它会一直运行到最后。

在您的代码中，您调用函数startproccess两次，而它应该只调用一次。

如果auth ==='undefined'，只需添加“return”，这样函数就会中断。
