How to get user email with google access token?

Question

I followed all these steps.

https://developers.google.com/+/web/signin/

I have client id and client secret.

I got access token now, how can I get user profile and email with access token? And how to check whether user logged in or not?

Answer 1

Using OAuth2, you can request permissions through the scope parameter. (Documentation.) I imagine the scopes you want are https://www.googleapis.com/auth/userinfo.email and https://www.googleapis.com/auth/userinfo.profile.

Then, it's a simple matter to get the profile info once you've obtained your access token. (I assume you've been able to redeem the returned authorization code for an access token?) Just make a get request to https://www.googleapis.com/oauth2/v1/userinfo?access_token={accessToken}, which returns a JSON array of profile data, including email:

{
    "id": "00000000000000",
    "email": "[email protected]",
    "verified_email": true,
    "name": "Fred Example",
    "given_name": "Fred",
    "family_name": "Example",
    "picture": "https://lh5.googleusercontent.com/-2Sv-4bBMLLA/AAAAAAAAAAI/AAAAAAAAABo/bEG4kI2mG0I/photo.jpg",
    "gender": "male",
    "locale": "en-US"
}

No guarantees, but try this:

$url = "https://www.googleapis.com/oauth2/v1/userinfo";
$request = apiClient::$io->makeRequest($client->sign(new apiHttpRequest($url, 'GET')));

if ((int)$request->getResponseHttpCode() == 200) {
    $response = $request->getResponseBody();
    $decodedResponse = json_decode($response, true);
    //process user info
  } else {
    $response = $request->getResponseBody();
    $decodedResponse = json_decode($response, true);
    if ($decodedResponse != $response && $decodedResponse != null && $decodedResponse['error']) {
      $response = $decodedResponse['error'];
    }
  }
}

Answer 2

try this

$accessToken = 'access token';
$userDetails = file_get_contents('https://www.googleapis.com/oauth2/v1/userinfo?access_token=' . $accessToken);
$userData = json_decode($userDetails);

if (!empty($userData)) {

  $googleUserId = '';
  $googleEmail = '';
  $googleVerified = '';
  $googleName = '';
  $googleUserName = '';

  if (isset($userData->id)) {
    $googleUserId = $userData->id;
  }
  if (isset($userData->email)) {
    $googleEmail = $userData->email;
    $googleEmailParts = explode("@", $googleEmail);
    $googleUserName = $googleEmailParts[0];
  }
  if (isset($userData->verified_email)) {
    $googleVerified = $userData->verified_email;
  }
  if (isset($userData->name)) {
    $googleName = $userData->name;
  }
} else {

  echo "Not logged In";
}

You just add this line into your scope Open your Application.cfc and then add this code

     <cfset request.oauthSettings = 
           {scope = "https://www.googleapis.com/auth/userinfo.email+https://www.googleapis.com/auth/userinfo.profile",
                                    client_id = "Your-id",
                                    client_secret = "your-secret",
                                    redirect_uri = "redirect-page",
                                    state = "optional"} />

Now you can get email from function that you can call like this

    <cfscript>              
        public function getProfile(accesstoken) {

            var h = new com.adobe.coldfusion.http();
            h.setURL("https://www.googleapis.com/oauth2/v1/userinfo");
            h.setMethod("get");
            h.addParam(type="header",name="Authorization",value="OAuth #accesstoken#");
            h.addParam(type="header",name="GData-Version",value="3");
            h.setResolveURL(true);
            var result = h.send().getPrefix();
            return deserializeJSON(result.filecontent.toString());
        }       
    </cfscript>

            <cfoutput>
            <cfset show = getProfile(session.ga_accessToken)>
            <cfdump var="#show#">
           </cfoutput>

Hope this can Help many of people to solve this . :)
