如何让 Facebook 应用程序登录工作 [英] How do I get Facebook Application Login to work

问题描述

我刚开始为 Facebook 制作应用程序，但我很早就遇到了问题.我希望人们做的第一步是授予访问他们个人资料的权限.网络上到处都是如何执行此操作的示例:

I just started making an application for Facebook, however I ran into problem early on. The first step I want people to do is to give permission to access their profile. All over the web are examples of how to do this with:

$user_id = $facebook->require_login();

但是，这是使用旧 PHP API 的方式.我已经在我的应用程序文件夹中下载并安装了新的，但它不再工作了.

However, this is the way it works using the Old PHP API. I have downloaded and installed the new one in my application folder and it is not working anymore.

我的问题是(我真的一直在寻找答案)使用新 API 执行此操作的代码是什么?

(以及相关问题:我现在刚开始制作应用程序时，是使用旧 API 更好，还是学习使用新 API 更好)

(and related question: is it better to use the old API, or learn to work with the new one when I am just starting making apps right now)

我现在有这个代码；

    <?php
        // Awesome Facebook Application
        //
        // Name: -
        //

        require_once 'facebook-php-sdk/src/facebook.php';
        $app_id = "-";
$app_secret = "-";

        // Create our Application instance.
$facebook = new Facebook(array(
        'appId' => $app_id,
        'secret' => $app_secret,
        'cookie' => true
));

$session = $facebook->getSession();
$loginUrl = $facebook->getLoginUrl(
        array(
        'canvas'    => 1,
        'fbconnect' => 0,
        'req_perms' => 'email,publish_stream,status_update,user_birthday, user_location,user_work_history'
        )
);

$fbme = null;

if (!$session) {
    echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
    exit;
}
else {
    try {
        $uid      =   $facebook->getUser();
        $fbme     =   $facebook->api('/me');

    } catch (FacebookApiException $e) {
        echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
        exit;
    }
}


echo "<p>hello, <fb:name uid=\"$user_id\" useyou=\"false\" />!</p>";


?>

推荐答案

下载并使用来自 github 的新代码.

Download and use new code from github.

如何获取用户权限?

$loginUrl = $facebook->getLoginUrl(array(
    'req_perms' => 'email,user_birthday,publish_stream,sms,status_update,user_location'
));

或

<fb:login-button perms="email,user_birthday,publish_stream,sms,status_update,user_location"></fb:login-button>

示例如何登录

更新

$session = $facebook->getSession();
$loginUrl = $facebook->getLoginUrl(
        array(
        'canvas'    => 1,
        'fbconnect' => 0,
        'req_perms' => 'email,publish_stream,status_update,user_birthday, user_location,user_work_history'
        )
);

$fbme = null;

if (!$session) {
    echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
    exit;
}
else {
    try {
        $uid      =   $facebook->getUser();
        $fbme     =   $facebook->api('/me');

    } catch (FacebookApiException $e) {
        echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
        exit;
    }
}
