你能帮我如何使用G+Javascript和PHP登录吗？Javascript运行良好，但当我想在服务器上验证令牌时，它会抛出异常。我按照这一页走：https://developers.google.com/identity/sign-in/web/backend-auth但是只有Java/Python。Javscript代码：
function onSignIn(googleUser)
{
var id_token = googleUser.getAuthResponse().id_token,
profile = googleUser.getBasicProfile();
console.log(id_token);
$.ajax({
url : "{link :Signgoogle:in}",
accepts : 'json',
type : 'post',
data : {
'token' : id_token
},
...
PHP代码：
public function actionIn()
{
$token = $_POST['token'];
$client = new 'Google_Client();
$client->setScopes('email');
$client->setApplicationName(self::APP_NAME);
$client->setDeveloperKey(self::SERVER_KEY);
$client->setAccessToken($token); // This throws an exception
$data = $client->verifyIdToken($token)->getAttributes();
...
$client->setAccessToken抛出异常：Could not json decode the token。你能告诉我如何验证用户登录吗？非常感谢。
我遇到了同样的问题，我为您的问题找到了以下解决方案：
auth2.attachClickHandler(element, {},
function(googleUser) {
var link = server+"user/google-plus-login"
console.log(link)
console.log(googleUser)
var Name = googleUser['wc']['Ld']
var mail = googleUser['wc']['wc']
var image = googleUser['wc']['zt']
var access_token = googleUser['Ka']['access_token']
}, function(error) {
alert(JSON.stringify(error, undefined, 2));
});
希望这也适用于你！
要获取客户端详细信息，只需将令牌传递给此apihttps://www.googleapis.com/oauth2/v3/tokeninfo?id_token=<your_token>
if (isset ( $_REQUEST['token'] ) && $_REQUEST['token'] != '') {
$response = file_get_contents ( 'https://www.googleapis.com/oauth2/v3/tokeninfo?id_token=' . $_REQUEST['token'] );
$response = json_decode ( $response );
echo "<pre>";
print_r ( $response );
echo "</pre>";
}

嘿，原因是您通过ajax传递id_token，而在php中，您在setAccessToken($token)中验证access_token。因此，为了验证和设置access_token，您必须发送access_token以及以下内容：
function onSignIn(googleUser)
{
var id_token = googleUser.getAuthResponse().id_token,
var access_token = googleUser.getAuthResponse(true).access_token,
profile = googleUser.getBasicProfile();
console.log(id_token);
$.ajax({
url : "{link :Signgoogle:in}",
accepts : 'json',
type : 'post',
data : {
'token' : id_token,
'access_token' : access_token
},
在像这样的后端检查中
public function actionIn()
{
$token = $_POST['token'];
$access_token = $_POST['access_token'];
$client = new 'Google_Client();
$client->setScopes('email');
$client->setApplicationName(self::APP_NAME);
$client->setDeveloperKey(self::SERVER_KEY);
$client->setAccessToken($access_token); // This will not throw exception
$data = $client->verifyIdToken($token)->getAttributes();
...
