使用从客户端收到的Google授权代码获取服务器端javascript(nodejs)上的访问令牌 [英] Get access token on server side javascript (nodejs) using google authorization code received from client side
问题描述
我已经阅读了此文档:- https://developers.google.com/identity/sign-in/web/server-side-flow
i have gone through this documentation :- https://developers.google.com/identity/sign-in/web/server-side-flow
在最后一步，它接收到授权代码，然后显示了使用Java或python库接收访问令牌和刷新令牌的示例，但是我在nodejs中找不到任何类似的示例. 我如何使用nodejs复制相同的示例? 我不能只是发送帖子或获取对某些Google oauth api的请求并使用授权码接收访问令牌吗?
At the last step it receives the authorization code and after that it shows the example of receiving access token and refresh token using java or python libraries, but i cant find any similar example in nodejs. How can i replicate the same example using nodejs? Can't i just send a post or get request to some google oauth api and receive the access token using authorization code?
先谢谢您了:)
推荐答案
Google API节点. js客户端库提供 oauth2Client.getToken(code, cb) 给出访问令牌(以及可选的刷新令牌)以交换授权代码:
Google APIs Node.js Client library offers oauth2Client.getToken(code, cb) which gives access token (and optionally refresh token) in exchange of the authorization code :
oauth2Client.getToken(code, function (err, tokens) {
// Now tokens contains an access_token and an optional refresh_token. Save them.
if (!err) {
oauth2Client.setCredentials(tokens);
}
});
可以在 https://github上找到官方示例. com/google/google-api-nodejs-client/tree/master/samples ，其中包括
An official example is available at https://github.com/google/google-api-nodejs-client/tree/master/samples which includes oauth2.js, an helper for the oauth part
您还可以在Paul Shan的本网站上找到完整的示例. ，这是使用 Google API Node.js客户端的nodejs示例.编辑ClientId和ClientSecret，运行此示例，然后转到 http://127.0.0.1:8081
You can also find a complete example on this site by Paul Shan, it's a nodejs example using Google APIs Node.js Client. Edit ClientId and ClientSecret, run this sample and go to http://127.0.0.1:8081
var http = require('http');
var express = require('express');
var Session = require('express-session');
var google = require('googleapis');
var plus = google.plus('v1');
var OAuth2 = google.auth.OAuth2;
const ClientId = "YOUR_CLIENT_ID";
const ClientSecret = "YOUR_CLIENT_SECRET";
const RedirectionUrl = "http://localhost:8081/oauthCallback";
var app = express();
app.use(Session({
secret: 'raysources-secret-19890913007',
resave: true,
saveUninitialized: true
}));
function getOAuthClient() {
return new OAuth2(ClientId, ClientSecret, RedirectionUrl);
}
function getAuthUrl() {
var oauth2Client = getOAuthClient();
// generate a url that asks permissions for Google+ and Google Calendar scopes
var scopes = [
'https://www.googleapis.com/auth/plus.me'
];
var url = oauth2Client.generateAuthUrl({
access_type: 'offline',
scope: scopes,
//use this below to force approval (will generate refresh_token)
//approval_prompt : 'force'
});
return url;
}
app.use("/oauthCallback", function(req, res) {
var oauth2Client = getOAuthClient();
var session = req.session;
var code = req.query.code;
oauth2Client.getToken(code, function(err, tokens) {
console.log("tokens : ", tokens);
// Now tokens contains an access_token and an optional refresh_token. Save them.
if (!err) {
oauth2Client.setCredentials(tokens);
session["tokens"] = tokens;
res.send(`
<html>
<body>
<h3>Login successful!!</h3>
<a href="/details">Go to details page</a>
<body>
<html>
`);
} else {
res.send(`
<html>
<body>
<h3>Login failed!!</h3>
</body>
</html>
`);
}
});
});
app.use("/details", function(req, res) {
var oauth2Client = getOAuthClient();
oauth2Client.setCredentials(req.session["tokens"]);
var p = new Promise(function(resolve, reject) {
plus.people.get({ userId: 'me', auth: oauth2Client }, function(err, response) {
console.log("response : ", response);
resolve(response || err);
});
}).then(function(data) {
res.send(`<html><body>
<img src=${data.image.url} />
<h3>Hello ${data.displayName}</h3>
</body>
</html>
`);
})
});
app.use("/", function(req, res) {
var url = getAuthUrl();
res.send(`
<html>
<body>
<h1>Authentication using google oAuth</h1>
<a href=${url}>Login</a>
</body>
</html>
`)
});
var port = 8081;
var server = http.createServer(app);
server.listen(port);
server.on('listening', function() {
console.log(`listening to ${port}`);
});
