问题描述

我刚刚接触php和google api，当用户使用Google+登录时，我正在尝试获取电子邮件地址，我使用$ plus-> people-> get（me ）但是当我尝试获取电子邮件地址失败与此错误：

PHP注意：未定义的索引：值

这是我的代码：

 <？php 
 session_start（）; 
 
 set_include_path（get_include_path（）。PATH_SEPARATOR。$ _SERVER ['DOCUMENT_ROOT']。/ src）; 
 
 require_once'Google / Client.php'; 
 
 require_once'Google / Service / Plus.php'; 
 
 $ client_id ='XXXXXXXXXXXXXXXXXXXX.apps.googleusercontent.com'; 
 $ client_secret ='XXXXXXXXXXXXXXXXXXX'; 
 $ redirect_uri ='http://www.XXXXXXXXXXXXXX.com/pruebas.php'; 
 
 $ client = new Google_Client（）; 
 $ client-> setClientId（$ client_id）; 
 $ client-> setClientSecret（$ client_secret）; 
 $ client-> setRedirectUri（$ redirect_uri）; 
 $ client-> addScope（https://www.googleapis.com/auth/userinfo.profile）; 
 $ client-> addScope（https://www.googleapis.com/auth/userinfo.email）; 
 
 $ plus = new Google_Service_Plus（$ client）; 
 
 if（isset（$ _ REQUEST ['logout']））{
 unset（$ _ SESSION ['access_token']）; 
} 
 
 if（isset（$ _ GET ['code']））{
 $ client-> authenticate（$ _ GET ['code']）; 
 $ _SESSION ['access_token'] = $ client-> getAccessToken（）; 
 $ redirect ='http：//'。 $ _SERVER ['HTTP_HOST']。 $ _SERVER [ PHP_SELF]; 
 header（'Location：'。filter_var（$ redirect，FILTER_SANITIZE_URL））; 
 
} 
 
 if（isset（$ _ SESSION ['access_token']）&&$ _SESSION ['access_token']）{
 $ client-> ; setAccessToken（$ _ SESSION [ 'ACCESS_TOKEN']）; 
 $ _SESSION ['token'] = $ client-> getAccessToken（）; 
 
} else {
 $ authUrl = $ client-> createAuthUrl（）; 
}

 printUrl：{$ me ['url']} \\\
< br>; 
 $ name3 = $ me ['name'] ['givenName']; 
 echoNombre：$ name3< br>; //一切正常，直到我尝试收到电子邮件
 $ correo =（$ me ['emails'] ['value']）; 
 echo $ correo; 
} 
？> 
< / body> 
< / html> 
  

我只需从$ me获取帐户电子邮件地址即可将其存储在我的应用程序中。 p>

谢谢。

解决方案

$ me ['emails'] 是一个数组，而不是一个哈希。所以添加一个 [0] 来选择第一个Mailadress：

  $ correo =（$ me [ '电子邮件'] [0] [ '值']）; 
  

现在应该可以正常运行...

I'm new to php and the google api, I'm trying to get the email address when the user sing in with Google+, I get all the User info using $plus->people->get("me") but when I try to get the email address it fails with this error:

PHP Notice: Undefined index: value

here is my code:

<?php
session_start();

set_include_path(get_include_path() . PATH_SEPARATOR . $_SERVER['DOCUMENT_ROOT'] . "/src");

require_once 'Google/Client.php';

require_once 'Google/Service/Plus.php';

$client_id = 'XXXXXXXXXXXXXXXXXXXX.apps.googleusercontent.com';
$client_secret = 'XXXXXXXXXXXXXXXXXXX';
$redirect_uri = 'http://www.XXXXXXXXXXXXXX.com/pruebas.php';

$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("https://www.googleapis.com/auth/userinfo.profile");
$client->addScope("https://www.googleapis.com/auth/userinfo.email");

$plus = new Google_Service_Plus($client);

if (isset($_REQUEST['logout'])) {
    unset($_SESSION['access_token']);
}

if (isset($_GET['code'])) {
    $client->authenticate($_GET['code']);
    $_SESSION['access_token'] = $client->getAccessToken();
    $redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
    header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));

}

if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
    $client->setAccessToken($_SESSION['access_token']);
    $_SESSION['token'] = $client->getAccessToken();

} else {
    $authUrl = $client->createAuthUrl();
}
?>

} else {
    print "<a class='logout' href='pruebas.php?logout'>Cerrar:</a>";
}

if (isset($_SESSION['access_token'])) {
    $me = $plus->people->get("me");

    print "<br>ID: {$me['id']}\n<br>";
    print "Display Name: {$me['displayName']}\n<br>";
    print "Image Url: {$me['image']['url']}\n<br>";
    print "Url: {$me['url']}\n<br>";
    $name3 = $me['name']['givenName'];
    echo "Nombre: $name3 <br>"; //Everything works fine until I try to get the email
    $correo = ($me['emails']['value']);
    echo $correo;
    }
?>
</body>
</html>

I just what to get the account email address from $me to store it on my app.

thanks.

解决方案

$me['emails'] is an Array, not a Hash. So add an [0] for choosing the first Mailadress:

$correo = ($me['emails'][0]['value']);

Now it should work fine...
