如何解决无法从Google API获取OAuth2令牌信息
我可以使用以下代码从Google api获取访问oauth2令牌：
<html><head></head><body>
<script>
var YOUR_CLIENT_ID =
'568020407566-s1tdctjbjeocf5nt20l64midfo1atu4h.apps.googleusercontent.com';
var YOUR_REDIRECT_URI =
'https://us-central1-hyperledger-poc.cloudfunctions.net/oauthjax';
var fragmentString = location.hash.substring(1);
// Parse query string to see if page request is coming from OAuth 2.0 server.
var params = {};
var regex = /([^&=]+)=([^&]*)/g,m;
while (m = regex.exec(fragmentString)) {
params[decodeURIComponent(m[1])] = decodeURIComponent(m[2]);
}
if (Object.keys(params).length > 0) {
localStorage.setItem('oauth2-test-params',JSON.stringify(params) );
if (params['state'] && params['state'] == 'try_sample_request') {
trySampleRequest();
}
}
// If there's an access token,try an API request.
// Otherwise,start OAuth 2.0 flow.
function trySampleRequest() {
var params = JSON.parse(localStorage.getItem('oauth2-test-params'));
if (params && params['access_token']) {
var xhr = new XMLHttpRequest();
xhr.open('GET','https://www.googleapis.com' +
'access_token=' + params['access_token']);
xhr.onreadystatechange = function (e) {
if (xhr.readyState === 4 && xhr.status === 200) {
console.log(xhr.response);
} else if (xhr.readyState === 4 && xhr.status === 401) {
// Token invalid,so prompt for user permission.
oauth2SignIn();
}
};
xhr.send(null);
} else {
oauth2SignIn();
}
}
/*
* Create form to request access token from Google's OAuth 2.0 server.
*/
function oauth2SignIn() {
// Google's OAuth 2.0 endpoint for requesting an access token
var oauth2Endpoint = 'https://accounts.google.com/o/oauth2/v2/auth';
// Create element to open OAuth 2.0 endpoint in new window.
var form = document.createElement('form');
form.setAttribute('method','GET'); // Send as a GET request.
form.setAttribute('action',oauth2Endpoint);
// Parameters to pass to OAuth 2.0 endpoint.
var params = {'client_id': YOUR_CLIENT_ID,'redirect_uri': YOUR_REDIRECT_URI,'scope': 'https://www.googleapis.com/auth/userinfo.email','state': 'try_sample_request','include_granted_scopes': 'true','response_type': 'token'};
// Add form parameters as hidden input values.
for (var p in params) {
var input = document.createElement('input');
input.setAttribute('type','hidden');
input.setAttribute('name',p);
input.setAttribute('value',params[p]);
form.appendChild(input);
}
// Add form to page and submit it to open the OAuth 2.0 endpoint.
document.body.appendChild(form);
form.submit();
}
</script>
<button onclick="trySampleRequest();">Try sample request</button>
</body></html>
我正在尝试使用https://oauth2.googleapis.com/tokeninfo?id_token=XYZ123 mentioned in below google document
https://developers.google.com/identity/protocols/oauth2/openid-connect#validatinganidtoken
我得到以下错误作为响应：
{
"error_description": "Invalid Value"
}
但是，如果我使用相同的令牌来获取用户信息，则通过使用以下代码和响应也可以正常工作
我尝试过的代码：
const token = req.body.access_token;
var options = {
host: 'www.googleapis.com',port: 443,//path: '/oauth2/v3/userinfo',path: '/oauth2/v3/tokeninfo?id_token='+token,method: 'GET',headers: {'Authorization': 'Bearer '+ token}
}
// making the https get call
let data;
var getReq = await https.request(options,function(response) {
response.on('data',(chunk) => {
data += chunk;
});
response.on('end',function() {
// Data reception is done,do whatever with it!
console.log("line 52");
// var parsed = JSON.parse(data);
console.log("line 54"+data);
res.send(data);
// console.log('data',parsed);
// console.log('endSTATUS: ' + parsed);
});
});
// console.log("response",recievedJSON);
/*getReq.on('end',function(){
res.send(valid);
});*/
getReq.end();
getReq.on('error',function(err) {
console.log('Error: ',err);
});
回复：
