带有gmail api的节点js,该API返回了错误:错误:authorized_client

node.js

编辑:在这段代码上发生错误:

   var gmail = google.gmail('v1');
      gmail.users.labels.list({
        auth: auth,
        userId: 'me',
      }, function(err, response) {
        if (err) {
          console.log('The API returned an error: ' + err);
          return;
        }

我正在使用Node js的gmail api。当我阅读他们的快速入门指南时,我会不断收到此错误。

https://developers.google.com/gmail/api/quickstart/nodejs

 The API returned an error: Error: unauthorized_client

请记住,我使用电子邮件地址进行了快速入门,一切都很好。完全没有错误。我决定为测试目的创建一个虚拟电子邮件。我所做的唯一更改是step 1-g关闭了client_secret.json文件以保留新的凭据和密钥。我尝试切换回旧文件,但错误仍然存​​在。

在页面底部的链接中提供了状态。

Authorization information is stored on the file system, so subsequent executions will not prompt for authorization. Would I have to clear or refresh the information? If so how can I do this?

如果有帮助,我会将所有代码重新发布到quickstart.js文件中。

var fs = require('fs');
var readline = require('readline');
var google = require('googleapis');
var googleAuth = require('google-auth-library');

var SCOPES = ['https://www.googleapis.com/auth/gmail.readonly'];
var TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH ||
    process.env.USERPROFILE) + '/.credentials/';
var TOKEN_PATH = TOKEN_DIR + 'gmail-nodejs-quickstart.json';

// 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
  // Gmail API.
  authorize(JSON.parse(content), listLabels);
});

/**

 * 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);
    }
  });
}

function getNewToken(oauth2Client, callback) {

      }
      oauth2Client.credentials = token;
      storeToken(token);
      callback(oauth2Client);
    });
  });
}

/**

 *
 * @param {Object} token The token to store to disk.
 */
function storeToken(token) {

    fs.mkdirSync(TOKEN_DIR);
  } catch (err) {
    if (err.code != 'EEXIST') {
      throw err;
    }
  }
  fs.writeFile(TOKEN_PATH, JSON.stringify(token));
  console.log('Token stored to ' + TOKEN_PATH);
}

/**

    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];

我做了console.log on TOKEN_PATH,它给了我文件所在的路径。

我必须删除文件

/Users/user/.credentials/gmail-nodejs-quickstart.json

这是我在Mac上找不到的隐藏文件夹。
