gmail API快速入门在google.gmail('v1')上失败 [英] gmail API quickstart failing at google.gmail('v1')
问题描述
我按照以下示例操作 https://developers.google.com/gmail/api/quickstart/nodejs
I followed the example at https://developers.google.com/gmail/api/quickstart/nodejs
运行此示例代码时,出现如下提示
When I run this sample code, I get prompted as follows
通过访问以下网址授权此应用: https://accounts.google.com/o/oauth2/ ....
Authorize this app by visiting this url: https://accounts.google.com/o/oauth2/....
我给予了宽容,并且给了我代码.然后,在示例程序的下一个提示中输入此代码.
I give permision and it gives me a code. I then enter this code in the next prompt of the sample program.
然后示例在
var gmail = google.gmail('v1'); TypeError:google.gmail不是 功能
var gmail = google.gmail('v1'); TypeError: google.gmail is not a function
我的节点版本为
node -v v8.9.4
node -v v8.9.4
API版本:
依赖项":{ "google-auth-library":"^ 0.12.0", "googleapis":"^ 26.0.1"}
"dependencies": { "google-auth-library": "^0.12.0", "googleapis": "^26.0.1" }
关于我做错了什么建议?
Any suggestions for what I did wrong?

推荐答案
快速入门指南适用于googleapis版本25,而不适用于版本26.
Quickstart guide works with version 25 of googleapis and not version 26.
快速入门指南未指定googleapis的版本.因此,它的合理用户将使用最新版本,就像我一样.
The quickstart guide does not specify a version of googleapis. So its reasonable users will use latest, just like I did.
指南中的代码
var google = require('googleapis');
需要更改为
var {google} = require('googleapis');
现在一切正常.
更正的版本
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/gmail-nodejs-quickstart.json
var SCOPES = ['https://www.googleapis.com/auth/gmail.readonly'];

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
