问题描述
我缺少什么？这似乎是所有的，但显然是内向外或向后。
任何和所有的帮助是赞赏！以下是代码：
<？php
$ app_id =xxxxxxxxxxxxxxxxxxxxxxxxxxx;
$ app_secret =xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx;
$ my_url =http://xxxxxxxxxxxxxxxxxxxxxx.com/testfiles/fbeventform.php;
//要获取PAGE访问代码
//首先获取用户访问代码
session_start（）;
$ code = $ _REQUEST [code];
if（empty（$ code））{
$ _SESSION ['state'] = md5（uniqid（rand（），TRUE））; // CSRF保护
$ dialog_url =https://www.facebook.com/dialog/oauth?client_id=
。 $ app_id。 & redirect_uri =。 urlencode（$ my_url）。 & state =

echo（< script> top.location.href ='$ dialog_url。'< / script>）;
}
if（$ _ REQUEST ['state'] == $ _SESSION ['state']）{

解决方案
在您的 $ url = https://graph.facebook.com/。 $ page_id。 /事件？ 。 $ access_token; 你缺少访问令牌的查询字符串名称
尝试这个
$ url =https://graph.facebook.com/。 $ page_id。 / events？access_token =。 $ access_token;
I'm getting tantalizingly close to completing this script. The goal is to Post an event to one of my fan page walls. The script is effectively grabbing the correct PAGE Access Token, and is effectively posting the event, but it's on my personal wall, not the page wall I'm trying to get it to.
What am I missing? It seems to be all there, but clearly something is inside out or backwards.
Any and all help is appreciated! Here's the code:
<?php
$app_id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$app_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$my_url = "http://xxxxxxxxxxxxxxxxxxxxxx.com/testfiles/fbeventform.php";
//Going to get the PAGE access code
//First to get USER Access Code
session_start();
$code = $_REQUEST["code"];
if(empty($code)) {
$_SESSION['state'] = md5(uniqid(rand(), TRUE)); //CSRF protection
$dialog_url = "https://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
. $_SESSION['state'] . "&scope=create_event&scope=manage_pages";
echo("<script> top.location.href='" . $dialog_url . "'</script>");
}
if($_REQUEST['state'] == $_SESSION['state']) {
$token_url = "https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret . "&code=" . $code;
$access_token = @file_get_contents($token_url);
$params = null;
parse_str($access_token, $params);
$graph_url = "https://graph.facebook.com/me?access_token="
. $params['access_token'];
$user = json_decode(file_get_contents($graph_url));
echo("Hello " . $user->name);
}
else {
echo("The state does not match. You may be a victim of CSRF.");
}
echo '<hr />' . $access_token;
//Now, getting the PAGE Access token, using the user access token
$page_token_url = "https://graph.facebook.com/" . $page_id . "?fields=access_token&" . $access_token;
$response = file_get_contents($page_token_url);
// Parse the return value and get the Page access token
$resp_obj = json_decode($response,true);
$page_access_token = $resp_obj['access_token'];
echo '<hr />' . $page_access_token;
//Post the event--here's the form function
if( !empty($_POST) && (empty($_POST['name']) || empty($_POST['start_time']) || empty($_POST['end_time'])) ) {
$msg = "Please check your inputs!";
} elseif(!empty($_POST)) {
$url = "https://graph.facebook.com/" . $page_id . "/events?" . $access_token;
$params = array();
// Prepare Event fields
foreach($_POST as $key=>$value)
if(strlen($value))
$params[$key] = $value;
// Check if we have an image
if( isset($_FILES) && !empty($_FILES['picture']['name']) ) {
$uploaddir = './upload/';
$uploadfile = $uploaddir . basename($_FILES['picture']['name']);
if (move_uploaded_file($_FILES['picture']['tmp_name'], $uploadfile)) {
$params['picture'] = "@" . realpath($uploadfile);
}
}
// Start the Graph API call
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
$result = curl_exec($ch);
$decoded = json_decode($result, true);
curl_close($ch);
if(is_array($decoded) && isset($decoded['id'])) {
// Event created successfully, now we can
// a) save event id to DB AND/OR
// b) show success message AND/OR
// c) optionally, delete image from our server (if any)
$msg = "Event created successfully: {$decoded['id']}";
}
}

解决方案
On your $url = "https://graph.facebook.com/" . $page_id . "/events?" . $access_token; you're missing the query string name for the access token
Try this
$url = "https://graph.facebook.com/" . $page_id . "/events?access_token=" . $access_token;
