[英]Grabbing permission from facebook user and posting to their wall
除了在Facebook應用提交后向用戶發布牆 (我的老問題)之外,我想出了以下代碼,但似乎不起作用? 我認為最好打開一個新問題,因為這是一個新問題。
我究竟做錯了什么? 另外,此代碼應放在哪里?
<?php
$session = $facebook->getSession();
//Is user logged in and has allowed this app to access its data
if (!$session) {
$loginUrl = $facebook->getLoginUrl(array(
'canvas' => 1,
'fbconnect' => 0,
'next' => 'enter.php',
'cancel_url' => 'index.php',
));
// use the $loginUrl created on the enter button to request permission;
}
$user_id = $facebook->getUser();
//post to wall
$attachment = array('message' => '<message>',
'name' => '<name here>',
'caption' => '<caption here>',
'link' => '<link to app>',
'description' => '<enter description >',
'picture' => '<enter image url>',
'actions' => array(array('name' => '<enter action label>',
'link' => '<enter action url>')
);
$permissions = $facebook->api("/me/permissions");
if( array_key_exists('publish_stream', $permissions['data'][0]) ) {
// Permission is granted!
// Do the related task
try {
$post_id = $facebook->api('/me/feed', 'post', $attachment);
} catch (CurlException $e) {
//timeout so try to resend
$post_id = $facebook->api('/me/feed', 'post', $attachment);
}
catch (FacebookApiException $e) {
error_log($e);
}
} else {
// We don't have the permission
// Alert the user or ask for the permission!
}
// store the post id in-case you need to delete later
?>
我只發布我正在使用的代碼即可。 希望能幫助到你
fbClass.php
public function __construct() {
// Naredimo instanco
$facebook = new Facebook(array(
'appId' => $this->fbid,
'secret' => $this->fbsecret,
'cookie' => true,
));
$this->facebook = $facebook;
}
function authUser($facebook) {
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will be needed depending on current user state.
if (!($user)) {
$loginUrl = $facebook->getLoginUrl(array(
'scope' => 'user_about_me, user_birthday, email, publish_stream',
'redirect_uri' => 'http://apps.facebook.com/myappname/',
));
echo("<script> top.location.href='" . $loginUrl . "'</script>");
} else {
return true;
}
}
process.php
$facebook = $fbClass->facebook;
$fbAuth = $fbClass->authUser($facebook);
if ($fbAuth) {
$res = $facebook->api('/me/feed/', 'post', array(
'message' => MESSAGE,
'name' => NAME,
'caption' => '',
'description' => DESC,
'picture' => PIC,
'link' => 'http://www.facebook.com/myapp/',
'actions' => array('name' => 'Test', 'link' => 'http://apps.facebook.com/myapp/')
));
}
您需要一個Facebook訪問令牌才能使此代碼正常工作。 將您的令牌添加到以下代碼中的“ My Access token here
中:
$attachment = array(
'access_token' => 'My Access token here',
'message' => '',
'name' => 'My Wall Post Header/Title Here',
'caption' => 'Small caption here',
'link' => 'http://www.mywebsite.org',
'description' => 'Wall Post Details Here',
'picture' => "http://www.mywebsite.org/images/logo.gif",
);
您可以在此處獲取訪問令牌。
