Question

我正在尝试使用Google Apps Script Node.js tutorial并将其调整为通用的Google Apps脚本函数调用者。这就是我想出来的

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

var SCOPES = ['https://www.googleapis.com/auth/drive'];
var TOKEN_DIR = path.dirname(path.dirname(path.dirname(process.execPath))) + '/other/credentials/';
var TOKEN_PATH = TOKEN_DIR + 'script-nodejs-quickstart.json';
//I ADDED THIS FUNCTION WITH THE PARAMETERS 
exports.run=function (myfunction,myparam){
// 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
  // Google Apps Script Execution API.
  console.log('one ran');
  //TRANSFER THE PARAMETERS TO authorize
  authorize(JSON.parse(content), callFunction,myfunction,myparam);
});
}

/**
 * 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,myfunction,myparam) {
  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);
      console.log('now two');
      //TRANSFER THE PARAMETES TO callFunction
      callback(oauth2Client,myfunction,myparam);
    }
  });
}

/**
 * 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: \n', 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);
}

/**
 * Call an Apps Script function to list the folders in the user's root
 * Drive folder.
 *
 * @param {google.auth.OAuth2} auth An authorized OAuth2 client.
 */
function callFunction(auth,myfunction,myparam) {
    console.log('now we are at the last');
  var scriptId = 'my apps script id';
  var script = google.script('v1');

  // Make the API request. The request object is included here as 'resource'.
  //PARAMETERS APPLIED 
  script.scripts.run({
    auth: auth,
    resource: {
      function: myfunction,
      parameters: myparam,
      devMode:true
    },
    scriptId: scriptId
  }, function(err, resp) {
  console.log(myfunction,myparam,auth);
    if (err) {
      // The API encountered a problem before the script started executing.
      console.log('The API returned an error: ' + err);
      return;
    }
    if (resp.error) {
      // The API executed, but the script returned an error.

      // Extract the first (and only) set of error details. The values of this
      // object are the script's 'errorMessage' and 'errorType', and an array
      // of stack trace elements.
      var error = resp.error.details[0];
      console.log('Script error message: ' + error.errorMessage);
      console.log('Script error stacktrace:');

      if (error.scriptStackTraceElements) {
        // There may not be a stacktrace if the script didn't start executing.
        for (var i = 0; i < error.scriptStackTraceElements.length; i++) {
          var trace = error.scriptStackTraceElements[i];
          console.log('\t%s: %s', trace.function, trace.lineNumber);
        }
      }
    } else {
      exports.result(resp.response.result);     
    }

  });
}
exports.result=function(result){
    return result;
}

CAPS中的所有内容都是我的评论。我的问题是每次我测试它都会返回：

The API returned an error: Error: ScriptError

api和app脚本的权限确实排成一行。所以这不是一个权限错误。它没有给我任何其他细节。有谁知道造成这个错误的原因是什么？

Answer 1

您可能有范围问题。我发现用于spreadhseets的正确范围是https://www.googleapis.com/auth/spreadsheets。这可以在File - ＆gt;下的脚本编辑器中看到。项目属性 - ＆gt;作用域。

Answer 2

这是由于Node.js库解析响应的早期问题，这在https://github.com/google/google-auth-library-nodejs/commit/323b794f3aa8bf7291041620155451c3f3b2b4d2中得到修复。如果您重新安装google-auth-library，则应该会看到完整的错误详情。

Answer 3

我遇到了同样的问题，并通过在我的脚本中添加适当的范围来解决。

通过查看“文件＆gt;项目属性＆gt;范围”，确保您的node.js脚本中的范围列表与应用程序脚本中的范围完全相同。

“快速入门”中未提及此功能，但以下文档对其进行了描述：https://developers.google.com/apps-script/guides/rest/api#general_procedure

错误：Node.js中的脚本错误到Google Apps脚本
