如何使用People API和Nodejs创建google联系人

Question

我正在搜索如何使用People API创建谷歌联系人，我在这里遵循了指南：

https://developers.google.com/people/quickstart/nodejs

我当前的代码：

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/contacts'];
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
const TOKEN_PATH = 'token.json';
// Load client secrets from a local file.
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 Tasks API.
authorize(JSON.parse(content), listConnectionNames);
});
/**
* 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) {
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 getNewToken(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 getNewToken(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);
});
});
}
/**
* Print the display name if available for 10 connections.
*
* @param {google.auth.OAuth2} auth An authorized OAuth2 client.
*/
function listConnectionNames(auth) {
const service = google.people({version: 'v1', auth});
service.people.connections.list({
resourceName: 'people/me',
pageSize: 2,
personFields: 'names,emailAddresses',
}, (err, res) => {
if (err) return console.error('The API returned an error: ' + err);
const connections = res.data.connections;
if (connections) {
console.log('Connections:');
connections.forEach((person) => {
if (person.names && person.names.length > 0) {
console.log(person.names[0].displayName);
} else {
console.log('No display name found for connection.');
}
});
} else {
console.log('No connections found.');
}
});
service.people.createContact({
requestBody: {
emailAddresses: [{value: '[e-mail]'}],
names: [
{
displayName: 'A',
familyName: 'B',
givenName: 'C',
},
],
},
});
//console.log('nnCreated Contact:', newContact);
}

我在reading联系人和创建OAuth身份验证密钥方面取得了成功。

https://developers.google.com/people/api/rest/v1/people/createContact(遗憾的是，这个链接没有像阅读联系人链接那样的完整工作示例(

我试图创建一个联系人添加此代码：

service.people.createContact({
requestBody: {
emailAddresses: [{value: '[e-mail]'}],
names: [
{
displayName: 'A',
familyName: 'B',
givenName: 'C',
},
],
},
});

但是，当我添加代码时，它返回一个错误：

Answer 1

错误：权限不足

意味着你正在尝试做一些你没有权限做的事情。

创建方法要求您已授权具有以下作用域的用户

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

我怀疑您已经更改了代码中的作用域，并且没有重新授权您的用户。

• 删除token.json
• 让用户访问权限找到你的应用程序并删除其访问权限。然后尝试再次运行您的应用程序

Answer 2

我将按照您提出问题的顺序回答您的问题：

1. 在文件credentials.json(来自第一个链接(中，它包含一个clientID，这个clientID将在'clientId':'上使用吗

是的，clientId是OAuth 2.0协议的一部分。

2. scope值是否发生变化或永远不变

脚本作用域只应在需要时更改。理想情况下，除非需要限制较少的作用域，否则应使用限制最严格的作用域。这里有一个有效的People API作用域列表。

3. 错误ReferenceError: gapi is not defined出了什么问题

此错误警告您尚未声明gapi变量。@ChavdaMadhav共享的原始代码并不是一个完整的例子。您需要填写空格才能运行它，其中包括gapi变量的定义。如果你对这个答案或其他答案有疑问，请毫不犹豫地回信。
