问题描述
我正在尝试从 Google OAuth2 获取新令牌,但我不断收到此错误:
这是我的代码(我使用 Expo 来构建 React Native 应用程序):
const uri = 'https://oauth2.googleapis.com/token'
const headerr = {
'Content-Type': 'Content-Type: application/x-www-form-urlencoded'
}
const bodyy = {
"client_id": '******************',"refresh_token": `${refreshToken}`,"grant_type":"refresh_token","access_type":"offline"
}
const fitnesss = await fetch(uri,{
method: "POST",headers: headerr,body: JSON.stringify(bodyy)
});
fitnesss.json().then(res => {
console.log(res)
})
有人知道如何解决这个问题吗?
解决方法
不受支持的授权类型意味着您使用的语言不支持授权类型刷新令牌。
这样做的原因是 JavaScript 是客户端的,这意味着您需要在代码中包含刷新令牌。在浏览器中查看过源代码的任何人都可以看到并使用您的刷新令牌。
要使用刷新令牌,请使用服务器端语言。例如 Node.js
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/drive.metadata.readonly'];
// 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 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) {
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,token) => {
if (err) return getAccessToken(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 getAccessToken(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,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);
});
});
}
