Google+ login api problems

问题:

I'm trying to implement google+ oauth2 login in my app and I am currently running into a few issues.

I am mainly following what is written here

It seems like the example is using a lot of libraries like twig, but I'm using maining pure php, and I don't think that part is causing any errors

The first issue I faced was that Google_HTTPRequest was not found. I read somewhere that composer names it Google_HTTP_Request, so I changed that and it seemed to have fixed that problem.

Then php was complaining that I was making a static call on a nonstatic function getIo(). So I changed to :: to -> because that was what made sense to me.

Then I am getting the error

PHP Fatal error:  Call to undefined method Google_IO_Curl::authenticatedRequest()

Which probably has something to do with what I changed.

The code I am running is

$google = new Google_Client();
$google->setApplicationName('Hamster Weebly');
$google->setClientId('CLIEnTID');
$google->setClientSecret('himitsudesuyo');
$google->setRedirectUri('postmessage');


$google->authenticate($_POST['AUTH_CODE']);
$token = json_decode($google->getAccessToken());

//$attrbutes = $google->verifyIdToken($token->id_token, '375022219321-us60lmg2cmeoj1aqpl784t7pbl1kg3jv.apps.googleusercontent.com')->getAttributes();

//error_log($attrbutes['payload']['sub']);

$reqUrl = 'https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=' . $token->access_token;
$req = new Google_Http_Request($reqUrl);

$tokenInfo = json_decode($google->getIo()->authenticatedRequest($req)->getResponseBody());


if ($token->error)
{
    http_response_code(500);
    exit;
}

// Make sure the token we got is for the intended user.
if ($tokenInfo->userid != $gPlusId) {
    http_response_code(401);
    echo json_encode("Token's user ID doesn't match given user ID");
    exit;
}
// Make sure the token we got is for our app.
if ($tokenInfo->audience != CLIENT_ID) 
{
    http_response_code(401);
    echo json_encode("Token's client ID does not match app");
    exit;
}

What is my issue?

回答1:

In the line:

$tokenInfo = json_decode($google->getIo()->authenticatedRequest($req)->getResponseBody());

getIo() should be changed to getAuth() due to (I think) a migration within the api.

After that, I encountered another error in which I changed:
if ($token->error) to if ( isset($tokenInfo->error) )

Good Luck!
