使用facebook php sdk登录后获取用户的Facebook信息 [英] Get user's facebook info after login using facebook php sdk
问题描述
我使用Facebook javascript sdk和php sdk登录用户到我的网络应用程序。使用javascript我有登录/外出工作，我可以获得登录用户的公共Facebook详细信息。
然而，当使用PHP时，我没有得到用户的Facebook详细信息。为了向您提供有关应用程序的一些信息，当我导航到包含表单的某个页面时，代码会检查他们是否已登录。如果没有，则会给他们一个LoginUrl链接。登录后，我有$ user_id，所以现在用户可以使用该表单，但是在提交表单时我没有将他们的facebook详细信息保存在MySQL数据库中。有没有人对我该做什么有建议？我肯定有$ user_id，因为只有我有$ user_id才显示表单。
我的代码基于https://developers.facebook.com/ docs / reference / php / facebook-api /
<？php
require ' facebook.php';
// 创建应用程序实例
$ config =数组（
' appId' => ' **************'，
' secret' => ' ****************************'，
' cookie' => true）;
$ facebook = new Facebook（$ config）;
$ user_id = $ facebook-> getUser（）;

//包含表单的页面
< div data-role = page id = postAJourney data-add-back-btn = true data-back-btn-text = 返回 data-rel = BAC k data-direction = reverse 数据转换 = flip data-theme = b >

尝试
{
< span class =code-comment> // 继续了解您已经过身份验证的登录用户。
$ user_profile = $ facebook-> api（' / me' ）;
echo 名称：。 $ user_profile [' name'];
// 商店会话数据
$ _SESSION [' fb_id'] = $ user_profile [' ID ];
$ _SESSION [' fb_name'] = $ user_profile [' name'];
$ _SESSION [' fb_first_name'] = $ user_profile [' first_name'];

$ _SESSION [' fbLink'] = https://www.facebook.com/。$ user_profile [' < span class =code-string> name'];
}
catch（FacebookApiException $ e）
{
// 如果用户已注销，则可以使用
// 用户ID，即使访问令牌无效。
// 在这种情况下，我们会得到一个例外，所以我们
// 只需要求用户再次登录。
$ login_url = $ facebook-> getLoginUrl（）;
error_log（$ e-> getType（））;
error_log（$ e-> getMessage（））;
}

// jQuery Mobile Form将在这里
<？ php else：？>
<？ php // 无用户，打印用户登录的链接
$ login_url = $ facebook-> getLoginUrl（array（
' < span class =code-string> scope' => ' email'，
' redirect_uri' => http：// localhost / share /＃postAJourney，
' display' => ' popup'，

使用由PHP SDK处理的OAuth 2.0登录：
< a href = <？php echo $ login_url;？> > 使用Facebook登录< / a >
< / div >
<？ php endif ？>
我根本没有收到用户详细信息。登录后，我会看到表单，网址包含更多数据，但不知道如何处理。我尝试了我提供的链接中的示例，我遇到了同样的问题。 -
user_id，所以现在用户可以使用该表单，但是在提交表单时我没有将他们的facebook详细信息保存在MySQL数据库中。有没有人对我该做什么有建议？我肯定有
user_id，因为只有我有
user_id才显示表格。

I am using Facebook javascript sdk and php sdk to login user to my web app. With javascript I have the login/out working and I can get a logged in user''s public facebook details.
However, when using php, I am not getting the user''s facebook details. To give you some info on the app, when I navigate to a certain page that contains a form, the code checks to see if their logged in. If not, they are given a LoginUrl link. Once logged in, I have the $user_id, so now the user can use the form, but I am not getting their facebook details to save in MySQL database when form is submitted. Does anyone have advice to what I should do? I definitely have the $user_id as the form is only shown if I have the $user_id.
I based my code on https://developers.facebook.com/docs/reference/php/facebook-api/
<?php
require 'facebook.php';
//create application instance
$config = array(
'appId' => '**************',
'secret' => '****************************',
'cookie' => true);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
?>
//Page containing form
<div data-role="page" id="postAJourney" data-add-back-btn="true" data-back-btn-text="back" data-rel="back" data-direction="reverse" data-transition="flip" data-theme="b" >
<div data-role="header" data-position="fixed">
<h1>Post A Journey</h1>
</div>
<div data-role="content">
<?php if ($user_id): ?>
<form action="add_journey.php" method="post" id="postAJourneyForm">
<?php
try
{
//Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
echo "Name: " . $user_profile['name'];
// store session data
$_SESSION['fb_id'] = $user_profile['id'];
$_SESSION['fb_name'] = $user_profile['name'];
$_SESSION['fb_first_name'] = $user_profile['first_name'];
$_SESSION['fb_last_name'] = $user_profile['last_name'];
$_SESSION['fbImg'] = "https://graph.facebook.com/".$user_profile['id']."/picture";
$_SESSION['fbLink'] = "https://www.facebook.com/".$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 = $facebook->getLoginUrl();
error_log($e->getType());
error_log($e->getMessage());
}
?>
//jQuery Mobile Form would be here
<?php else: ?>
<?php // No user, print a link for the user to login
$login_url = $facebook->getLoginUrl(array(
'scope' => 'email',
'redirect_uri' => "http://localhost/share/#postAJourney",
'display' => 'popup',
));
?>
<div>
Login using OAuth 2.0 handled by the PHP SDK:
<a href="<?php echo $login_url; ?>">Login with Facebook</a>
</div>
<?php endif ?>
I''m not getting user details at all. After I login and I am shown the form, the url contains more data but not sure what to do with that. I tried the example from the link I provided and I have the same issue. –
user_id, so now the user can use the form, but I am not getting their facebook details to save in MySQL database when form is submitted. Does anyone have advice to what I should do? I definitely have the
user_id as the form is only shown if I have the
user_id.
I based my code on https://developers.facebook.com/docs/reference/php/facebook-api/
<?php require 'facebook.php'; //create application instance
