Question

所以基本上我在这里所做的就是为了我自己的目的而劫持了google sheet api node.js快速入门指南。这里的一切都很有效，直到它到达我的spreadsheets.batchUpdate，然后一切都变得古怪。

如果我在spreadsheets.batchUpdate中注释掉“auth”初始化，我会收到错误消息：The API returned an error: Error: The request does not have valid authentication credentials.

如果我在spreadsheets.batchUpdate中注释掉“auth”初始化，我会收到错误消息：The API returned an error: Error: Request had insufficient authentication scopes.

我试图对这些调用进行的操作是从表单中获取一些数据，然后删除行，但我无法弄清楚此身份验证问题。

var fs = require('fs');
var updateDB = require('./updateDB.js');
var readline = require('readline');
var google = require('googleapis');
var googleAuth = require('google-auth-library');
var splitData;

    process.env.USERPROFILE) + '/.credentials/';

var array = [];

var run = {
  runQuickstart : function() {
    // 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 Sheets API.
      authorize(JSON.parse(content), listMajors);
    });
  }
}

https://www.googleapis.com/auth/spreadsheets.readonly会给你阅读权。您需要使用https://www.googleapis.com/auth/spreadsheets范围来更新工作表。

https://www.googleapis.com/auth/spreadsheets.readonly

Allows read-only access to the user's sheets and their properties.

https://www.googleapis.com/auth/spreadsheets

Allows read/write access to the user's sheets and their properties.

在多次调用Google工作表时，API身份验证不适用于第二次调用：请求的身份验证范围不足
