【问题描述】:
我试图简单地列出我的谷歌驱动器中的文件。我正在关注 nodeJS 教程:https://developers.google.com/drive/api/v3/quickstart/nodejs
我试图了解我哪里出错了。我的代码和教程里的一模一样。
const fs = require('fs');
const readline = require('readline');
const {google} = require('googleapis');
// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];
// 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 Drive API.
authorize(JSON.parse(content), listFiles);
});
/**
* 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);
});
});
}
/**
* Lists the names and IDs of up to 10 files.
* @param {google.auth.OAuth2} auth An authorized OAuth2 client.
*/
function listFiles(auth) {
const drive = google.drive({version: 'v3', auth});
drive.files.list({
pageSize: 10,
fields: 'nextPageToken, files(id, name)',
}, (err, res) => {
if (err) return console.log('The API returned an error: ' + err);
const files = res.data.files;
if (files.length) {
console.log('Files:');
files.map((file) => {
console.log(`${file.name} (${file.id})`);
});
} else {
console.log('No files found.');
}
});
}
其他一些注意事项:
- 我用
yarn add googleapis@39安装了google drive api库,所以我使用的是v39的api。 - 我按照教程中的说明制作了我的凭据,并下载了生成的文件
- 我已调试并确认 listFiles 中的 auth 对象已定义且凭据存在
任何想法都会很棒。如果有帮助的话,我也在运行节点 16.13.1 和纱线 1.22.10
【问题讨论】:
-
整个日志输出丢失...API 响应可能是准确的。
-
日志输出只是
The API returned an error: Error: No access, refresh token or API key is set. -
查看堆栈转储后,我发现
google-auth-library/build/src/auth/oauth2client.js的第 274 行出现错误。检查!thisCreds.access_token && !thisCreds.refresh_token && !this.apiKey时似乎失败了。这真的很奇怪,因为我的令牌存储在thisCreds.tokens.access_token, thisCreds.tokens.refresh_token等中。正如您在上面的代码中看到的,我从google.auth.OAuth2的getToken函数中获得了这个令牌。我想知道这是否是一个错误?
