我一直在尝试阅读朋友的新闻提要以检查我的消息是否存在（无论消息是可见、隐藏还是删除），如果消息存在，则不要发布新消息。如果它不存在，则发布消息。下面的代码有很多不必要的代码来追踪问题的来源。我为“publish_stream，read_stream”设置了权限。
我尝试了其他博客中的所有代码，但似乎没有工作我不知道是不是因为我使用的是 PHP SDK 3.0 - 最新版本。我的应用程序是 iframe 应用程序。甚至在 Facebook 应用程序上购买了一本昂贵的书（太贵了），但购买后发现它已经过时了！
如果我使用 /me 或我的用户 ID 但不是我朋友的 ID，则该代码运行良好。
require 'config.php';
require 'facebook.php';
//Create facebook application instance.
$facebook = new Facebook(array(
'appId' => $fb_app_id,
'secret' => $fb_secret
));
$sent = false;
$userData = null;
$PPnotposted = true;
$me = null;
$test_friends =1;
$user = $facebook->getUser();
// Login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl(array("next"=> "<? echo $fb_app_url ?>" ));
} else {
$loginUrl = $facebook->getLoginUrl( array( 'scope'=> 'publish_stream, read_stream', 'redirect_uri' => $fb_app_url));
}
$get_someone_else = 100000xxxxxxxxx; // I used a real user id but covered it up here so
my friend's id hidden for this stackexchange help
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
if ( $get_someone_else ){
$user_profile = $facebook->api("/".$get_someone_else);
echo "<br/> ********************user is ".$get_someone_else." ******************<br/>";
var_dump( $user_profile );
echo "<br/> ********************** end of user info ******************<br/>";
} else {
$user_profile = $facebook->api('/me');
}
} catch (FacebookApiException $e) {
}
// print_r( $user_profile );
$PPaccesstoken = $facebook->getAccessToken();
$attachment[access_token]= $PPaccesstoken ;
//post message to wall if it is sent through form
if(isset($_POST['PPmessage'])){
try {
if( $get_someone_else ){
$ppmy_news = $facebook->api("/.$get_someone_else./feed?limit=300"); //Get 300 messages to examine
echo "<br/> *********************** news feed is ".$ppmy_news." ******************<br/>";
var_dump( $ppmy_news );

} else {

//to examine. Initially I set it to
// 10 messages for testing purposes.
}
// var_dump( $ppmy_news);
// $sent = $facebook->api("/".$user."/feed", 'POST', $attachment );
$ppmy_view_lp=0;
if( $test_friends ) { //Debugging flag to activate or deactivate parts of code
echo "sent is :<br />";
// var_dump( $sent );
echo "<br />";
$friends = $facebook->api('/me/friends');
echo "friends is :<br />";
// var_dump( $friends );
echo "<br />";
$friendsLists = $facebook->api('/me/friends');
$total_friends = 0;
foreach ($friendsLists as $friends) {
foreach ($friends as $friend) {
$id = $friend['id'];
$name = $friend['name'];
$total_friends++; //Get total number of friends
echo "friend : ".$name." id is: ".$id." Total friends is : ".$total_friends." <br/> ";
}
}
}
} catch (FacebookApiException $e) {
echo "<br/> !!!!!!!!!!!! Error Dump Line 85 !!!!!!!!!!!!! <br/>";
var_dump( $e );
echo "<br/> !!!!!!!!!!!! End of Error Dump !!!!!!!!!!!!! <br/>";
//do something about it
}
}
}
但我发现我被拒绝许可，并且捕获转储是：

请帮帮我，让我知道我是否错误地设置了权限以及如何正确设置。
