我有一个基于 PHP 的网站 www.darooadda.com。我想知道是否有任何 facebook API 可以从 facebook 帐户邀请 friend 。如果用户使用 facebook 帐户登录该网站，他应该能够从该网站邀请他的 facebook 好友。
任何人都可以帮助我提供正确的 api 文档或相同的示例 php 代码吗？
最佳答案
此示例代码可以使用 facebook API 3.0.1，请求 friend 并在请求发送后发回您的站点
$<?php
// Requires Facebook PHP SDK 3.0.1: https://github.com/facebook/php-sdk/
require ('includes/facebook.php');
define('FACEBOOK_APP_ID',"your facebook ID");
define('FACEBOOK_SECRET',"your facebook secret password");
$user = null;
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => FACEBOOK_APP_ID,
'secret' => FACEBOOK_SECRET,
'cookie' => true
));
$user = $facebook->getUser();
$loginUrl = $facebook->getLoginUrl();
if ( empty($user) ) {
echo("<script> top.location.href='" . $loginUrl . "'</script>");
exit();
}
?>
<!doctype html>
<html>
<head>
<title>Send An Application Request Using The Facebook Graph API</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
</head>
<body>
<div id="fb-root"></div>
<a href="#">Send Application Request</a>
<script>
window.fbAsyncInit = function() {
FB.init({
appId: '<?php echo $facebook->getAppID() ?>',
status: true,
cookie: true,
oauth: true
});
};
$('a').click(sendRequest);
function sendRequest() {
FB.ui({
method: 'apprequests',
message: 'Check out this application!',
title: 'Send your friends an application request',
},
function (response) {
if (response.request && response.to) {
var request_ids = [];
for(i=0; i<response.to.length; i++) {
var temp = response.request + '_' + response.to[i];
request_ids.push(temp);
}
var requests = request_ids.join(',');
$.post('handle_requests.php',{uid: '<?php echo $user; ?>', request_ids: requests},function(resp) {
// callback after storing the requests
});
} else {
alert('canceled');
}
});
return false;
}
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
</body>
