如何从 NodeJS API 将图像上传到谷歌驱动器

In the below example, the file is fetched from files/photo.jpg and is renamed as photo.jpg and uploaded to the root folder of Google Drive.

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.file'];
const TOKEN_PATH = 'token.json';

/**
 * Create an OAuth2 client with the given credentials, and then execute the given callback function.
 */
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);
        });
    });
}
/**
* Describe with given media and metaData and upload it using google.drive.create method()
*/ 
function uploadFile(auth) {
  const drive = google.drive({version: 'v3', auth});
  const fileMetadata = {
    'name': 'photo.jpg'
  };
  const media = {
    mimeType: 'image/jpeg',
    body: fs.createReadStream('files/photo.jpg')
  };
  drive.files.create({
    resource: fileMetadata,
    media: media,
    fields: 'id'
  }, (err, file) => {
    if (err) {
      // Handle error
      console.error(err);
    } else {
      console.log('File Id: ', file.id);
    }
  });
}

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), uploadFile);
});

第 3 步:更改上传文件的名称

在 uploadFile 功能中，更改 name 属性.

const fileMetadata = {
        'name': 'any_name_you_like'
};

const media = {
     mimeType: 'any_mime_type',
     body: fs.createReadStream('files/photo.jpg')
};

const fileMetadata = {
        'name': 'any_file_name',
        parents: ['1xxxXj_sdsdsdsd0Rw6qDf0jLukG6eEUl']
};
