我需要在CRONJOB中运行查询，检查2个FBuser是否是共同的朋友： 类似以下内容，但我收到此错误：
Warning: file_get_contents(https://graph.facebook.com/fql?q=SELECT......) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in...
我收到以下错误：
{
"error": {
"message": "(#601) Parser error: unexpected '+' at position 6.",
"type": "OAuthException",
"code": 601
}
} )
这是剧本：
// get App AccessToken
$app_token_url = "https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $appId
. "&client_secret=" .$secret
. "&grant_type=client_credentials";
$response = file_get_contents($app_token_url);
$params = null;
parse_str($response, $params);
$App_access_token = $params['access_token'];
try { $permissions = $facebook->api('/'.$user1.'/permissions');
} catch(Exception $o){ $log[] = "//*** error on $user1/permissions > $o"; }
$permessi=$permissions[data][0];
if(array_key_exists('read_stream', $permessi) or array_key_exists('read_friendlists', $permessi) ) {
$fql_q = "SELECT 'uid1','uid2' FROM friend WHERE 'uid1'='$user1' AND 'uid2'='$user2'";
$fql_q = urlencode($fql_q);
$fql_query_url = "https://graph.facebook.com"
."/fql?q=$fql_q"
."&access_token=$App_access_token";
$fql_query_result = file_get_contents($fql_query_url);
$fql_query_obj = json_decode($fql_query_result, true);
if(is_array($fql_query_obj)){
$CountFriends = $CountFriends + 1;
}
