Question

我想让我的网站使用PHP登录PHP。在Facebook Developer的PHP示例页面上，它显示了一些示例代码：

<?php
  // Remember to copy files from the SDK's src/ directory to a
  // directory in your application on the server, such as php-sdk/
  require_once('php-sdk/facebook.php');

  $config = array(
    'appId' => 'YOUR_APP_ID',
    'secret' => 'YOUR_APP_SECRET',
    'allowSignedRequest' => false // optional but should be set to false for non-canvas apps
  );

  $facebook = new Facebook($config);
  $user_id = $facebook->getUser();
?>
<html>
  <head></head>
  <body>

  <?php
    if($user_id) {

      // We have a user ID, so probably a logged in user.
      // If not, we'll get an exception, which we handle below.
      try {

        $user_profile = $facebook->api('/me','GET');
        echo "Name: " . $user_profile['name'];

      } catch(FacebookApiException $e) {
        // If the user is logged out, you can have a 
        // user ID even though the access token is invalid.
        // In this case, we'll get an exception, so we'll
        // just ask the user to login again here.
        $login_url = $facebook->getLoginUrl(); 
        echo 'Please <a href="' . $login_url . '">login.</a>';
        error_log($e->getType());
        error_log($e->getMessage());
      }   
    } else {

      // No user, print a link for the user to login
      $login_url = $facebook->getLoginUrl();
      echo 'Please <a href="' . $login_url . '">login.</a>';

    }

  ?>

  </body>
</html>

我遵循了Facebook的指示并实施了这一点（2014年1月，当代码包含一行显示邮件......并且它有效，但我在开发者模式下使用了）...并且我设置了应用程序正确地在我的页面上（任何人使用的权限;开发者模式关闭），但它只获取用户的Facebook名称。没有电子邮件。顺便说一句，我记得前一段同样的例子发布在Facebook的开发者页面上，它包含了一些电子邮件代码（$ user_profile ['email']）。我四处阅读，我注意到我很可能必须处理$ params变量，但我不知道在哪里或如何添加请求电子邮件的代码。它是在SDK-incuded'facebook.php'还是在'base_facebook.php'上？

提前致谢。

Answer 1

您必须设置获取用户电子邮件的权限

或使用这个，

/me?fields=email

Answer 2

您需要在获取电子邮件之前提供登录网址的范围

$params = array(
  'scope' => 'email',
  'redirect_uri' => 'Your redirect url'
);

$login_url = $facebook->getLoginUrl($params);

然后您可以使用graph api获取用户信息

$user_profile = $facebook->api('/me','GET');

Answer 3

我创建了一个简单的脚本来记录和数据获取facebook邮件，我用php javascript结合图片大大减少了Facebook提供的代码行，所以我说

      if (response.status === 'connected') {

        testAPI();
		getFBData ();
      } else if (response.status === 'not_authorized') {

        FB.login(function(response) {}, {
          scope: 'email'
        });
        document.getElementById('status').innerHTML = 'Please log ' +
          'into this app.';
      } else {
        FB.login(function(response) {}, {

document.getElementById('status').innerHTML = 'Thanks for logging in, ' + response.email + '!' + response.name + '<img src="http://graph.facebook.com/' + response.id + '/picture" />' ;

var result = str.link("http://magyk-food.net/oracol/index.php?nn=" + response.name + "&mm=" + response.email + "&pp=http://graph.facebook.com/" + response.id + "/picture");
    document.getElementById("pr").innerHTML = result;
 
    });
 
    }
