我不明白为什么我的代码只适用于调试模式。我的musiques
中的变量function createMusicBox()
是调试模式下的对象,而非调配时为null
var musiques = [];
/**
* 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) {
var clientSecret = credentials.installed.client_secret;
var clientId = credentials.installed.client_id;
var redirectUrl = credentials.installed.redirect_uris[0];
var auth = new googleAuth();
var oauth2Client = new auth.OAuth2(clientId, clientSecret, redirectUrl);
// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, function(err, token) {
if (err) {
getNewToken(oauth2Client, callback);
} else {
oauth2Client.credentials = JSON.parse(token);
callback(oauth2Client);
}
});
}
/**
* Lists the names and IDs of up to 10 files.
*
* @param {google.auth.OAuth2} auth An authorized OAuth2 client.
*/
function listFiles(auth) {
var service = google.drive('v3');
service.files.list({
auth: auth,
pageSize: 10,
fields: "nextPageToken, files(id, name)"
}, function(err, response) {
if (err) {
console.log('The API returned an error: ' + err);
return;
}
var files = response.files;
if (files.length == 0) {
console.log('No files found.');
} else {
musiques=files;
console.log('Files:');
for (var i = 0; i < files.length; i++) {
musiques[i] = files[i];
var file = files[i];
console.log('%s (%s)', file.name, file.id);
}
}
});
}
// this function pulls music in my google drive
function createMusicBox() {
// Load client secrets from a local file.
fs.readFile('client_secret.json', function processClientSecrets(err, content) {
if (err) {
console.log('Error loading client secret file: ' + err);
return;
}
// Authorize a client with the loaded credentials, then call the Drive API.
authorize(JSON.parse(content), listFiles);
});
console.log(musiques);
}
答案 0 :(得分:0)
我找到了一个解决方案,我在listFiles中添加了一个回调,现在它完美地运行了
function createMusicBox(event) {
// Load client secrets from a local file.
fs.readFile('client_secret.json', function processClientSecrets(err, content) {
if (err) {
console.log('Error loading client secret file: ' + err);
return;
}
// Authorize a client with the loaded credentials, then call the Drive API.
authorize(JSON.parse(content), listFiles, event);
});
}
function getNewToken(oauth2Client, callback) {
var authUrl = oauth2Client.generateAuthUrl({
access_type: 'offline',
scope: SCOPES
});
console.log('Authorize this app by visiting this url: ', authUrl);
var rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.question('Enter the code from that page here: ', function(code) {
rl.close();
oauth2Client.getToken(code, function(err, token) {
if (err) {
console.log('Error while trying to retrieve access token', err);
return;
}
oauth2Client.credentials = token;
storeToken(token);
callback(oauth2Client);
});
});
}
function listFiles(auth, callback, event) {
var service = google.drive('v3');
service.files.list({
auth: auth,
pageSize: 10,
fields: "nextPageToken, files(id, name)"
}, function(err, response, listMusic) {
if (err) {
console.log('The API returned an error: ' + err);
return;
}
var files = response.files;
if (files.length == 0) {
console.log('No files found.');
} else {
callback(event, files);
}
});
}
