GCM 消息未在 PHP 内到达目的地

Question

我正在尝试发送 GCM 通知给定服务器操作 sendGroupMessage。目前，虽然我已经实现了它的功能以响应 echo $testGCM;

，但 GCM 消息没有发送

case "sendGroupMessage":
        if ($userId = authenticateUser($db, $username, $password, $gcmregid)) 
        {   
            if (isset($_REQUEST['toGroupId']))
            {   // instead of toUserName it's to a groupId
                $toGroupName = $_REQUEST['toGroupName'];
                $toGroupId   = $_REQUEST['toGroupId'];  
                $message     = $_REQUEST['messageText'];
                $campaign    = $_REQUEST['campaign_id'];
                $location    = $_REQUEST['location_id'];

                // Query to get the users id's who are in the group but not the user sending the message        
                $sqlGroupMembers = "SELECT DISTINCT usersId from users_groups 
                     WHERE usersId != '".$userId."' AND groupId = '".$toGroupId."'";


                // Loop to create a copy of message for all users taht are part of that group
                if($getGroupMembersId = $db->query($sqlGroupMembers)) 
                {
                    while($rowGroupMembers = $db -> fetchObject($getGroupMembersId))
                    {
                        $sql22 = "INSERT INTO `group_messages` (`myId`,`fromUser`, `fromUId`,`toGroupName`,`toGroupId`, `sentdt`, `read`, `readdt`, `messageText`,`shared_campaign_id`,`shared_campaign_location_id`) 
                              VALUES ('".$rowGroupMembers->usersId."','".$username."', '".$userId."','".$toGroupName."', '".$toGroupId."', '".DATE("Y-m-d H:i")."', '0', '".DATE("Y-m-d H:i")."', '".$message."','".$campaign."','".$location."');";                        

                        error_log("$sql22", 3 , "error_log");
                        if ($db->query($sql22)) 
                        {
                                $out = SUCCESSFUL;
                                echo testGCM(); // Testing the actions
                        }               
                        else 
                        {
                                $out = FAILED;
                        }                   

                    }   

                }                   

            }
            else
            {
                $out = FAILED;
            }           

        }
        else
        {
            $out = FAILED;
        }   
    break;

测试 GCM 操作：

function testGCM() {
    $gcmRegID  =  '(users GCM regID)'
    $pushMessage = $_POST["syncNewData"];   
    if (isset($gcmRegID) && isset($pushMessage)) {      
        $gcmRegIds = array($gcmRegID);
        $message = array("syncNewData" => $pushMessage);    
        $pushStatus = sendPushNotificationToGCM($gcmRegIds, $message);
    }       
}

发送通知方法：

function sendPushNotificationToGCM($registatoin_ids, $message) {
        //Google cloud messaging GCM-API url
        $url = 'https://android.googleapis.com/gcm/send';
        $fields = array(
            'registration_ids' => $registatoin_ids,
            'data' => $message,
        );
        // Google Cloud Messaging GCM API Key
        define("GOOGLE_API_KEY", "(Google API Key)"); // My API Key form Google console
        $headers = array(
            'Authorization: key=' . GOOGLE_API_KEY,
            'Content-Type: application/json'
        );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);   
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
        $result = curl_exec($ch);               
        if ($result === FALSE) {
            die('Curl failed: ' . curl_error($ch));
        }
        curl_close($ch);
        return $result;
    }

您的 testGCM() 函数似乎有问题。您可以记录 $pushStatus 变量以查看那里有什么或者它是否为空。也没有代码解析请求后返回的 JSON 数组。您可以查看 logcat 中的错误日志来调查问题。
