我正在開發一個小型項目,我對使用Google Drive方便使用感興趣。該程序的主要前提是在激活lambda函數時將新行插入到Google表格中。我寧願爲這個項目使用Node.js,但是可以使用Java或Python。修改AWS Sheet的Google Lambda

tutorial網站很容易看到這一切如何運作。你提出請求,你有OAuth,然後程序按照它的要求去做。不過,我正在尋找一種方法讓我的AWS lambda函數與我的谷歌驅動器中的文件夾進行交談並隨意更新工作表。

從本教程的代碼如下:

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

// If modifying these scopes, delete your previously saved credentials 
// at ~/.credentials/drive-nodejs-quickstart.json 
var SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly']; 
var TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH || 
    process.env.USERPROFILE) + '/.credentials/'; 
var TOKEN_PATH = TOKEN_DIR + 'drive-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 
    // 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) { 
    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); 
    } 
    }); 
} 

/** 
* 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 to call with the authorized 
*  client. 
*/ 
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); 
    }); 
    }); 
} 

/** 
* Store token to disk be used in later program executions. 
* 
* @param {Object} token The token to store to disk. 
*/ 
function storeToken(token) { 
    try { 
    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); 
} 

/** 
* 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 { 
     console.log('Files:'); 
     for (var i = 0; i < files.length; i++) { 
     var file = files[i]; 
     console.log('%s (%s)', file.name, file.id); 
     } 
    } 
    }); 
} 

目前已經得到了一些辦法,我可以給lambda函數特殊,授權,訪問我的谷歌驅動器文件夾,而不需要選擇的OAuth選項(一個Gmail賬戶而另一個)。

此外,在開發人員控制檯中,還有一個選項將白名單標題爲授權的JavaScript原始地址。有人知道從AWS Lambda進行標註時使用的網址嗎?

您可能可以將OAuth令牌的內容保留爲腳本中的字符串。 –

您需要一個代理服務,並在其中運行Google憑證。這樣你就不需要詢問用戶認證。代理服務已擁有訪問權限的憑證。以下是我用來代理連接到Google API的服務。
