C2DM实现PHP代码 [英] C2DM implementation PHP code

问题描述

我正在创建使用 C2DM 推送通知的 Android 应用程序.但是我在创建 php 代码以使用 c2dm 发送消息时遇到问题.请指导我如何使用 php 代码发送消息.实际上，关于如何获取客户端身份验证令牌存在一个问题.我见过 http://code.google.com/android/c2dm/index.html#server url 但据此我创建了 android 应用程序，我也得到了注册 ID，我也发送给用户，但服务器如何使用它来发送应用程序.

I am creating the Android application where C2DM push notification is used. But i have a problem in creating the php code to use c2dm for sending messages. please guide me how to use the php code to send the messages. Actually there is a problem regarding this that how to get client auth token. I have seen the http://code.google.com/android/c2dm/index.html#server url but according to this i have created the android application and i got the registration id also and i also send to the user but how server uses this to send the application.

安卓设备的服务器需要什么来发送消息吗?.

is there anything needed for the server from the android device to send the messages?.

推荐答案

注册自己的服务器系统并获取授权令牌(这是Cpt. Ohlund提出的):

To register your own server system and obtain the Authorise Tokens (this is what Cpt. Ohlund proposed):

function googleAuthenticate($username, $password, $source="Company-AppName-Version", $service="ac2dm") {    


        session_start();
        if( isset($_SESSION['google_auth_id']) && $_SESSION['google_auth_id'] != null)
            return $_SESSION['google_auth_id'];

        // get an authorization token
        $ch = curl_init();
        if(!ch){
            return false;
        }

        curl_setopt($ch, CURLOPT_URL, "https://www.google.com/accounts/ClientLogin");
        $post_fields = "accountType=" . urlencode('HOSTED_OR_GOOGLE')
            . "&Email=" . urlencode($username)
            . "&Passwd=" . urlencode($password)
            . "&source=" . urlencode($source)
            . "&service=" . urlencode($service);
        curl_setopt($ch, CURLOPT_HEADER, true);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);    
        curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        // for debugging the request
        //curl_setopt($ch, CURLINFO_HEADER_OUT, true); // for debugging the request

        $response = curl_exec($ch);

        //var_dump(curl_getinfo($ch)); //for debugging the request
        //var_dump($response);

        curl_close($ch);

        if (strpos($response, '200 OK') === false) {
            return false;
        }

        // find the auth code
        preg_match("/(Auth=)([w|-]+)/", $response, $matches);

        if (!$matches[2]) {
            return false;
        }

        $_SESSION['google_auth_id'] = $matches[2];
        return $matches[2];
    }

向手机发送消息:

// $msgType: all messages with same type may be "collapsed": if multiple are sent,
// only the last will be received by phone. 
function sendMessageToPhone($authCode, $deviceRegistrationId, $msgType, $messageText) {

            $headers = array('Authorization: GoogleLogin auth=' . $authCode);
            $data = array(
                'registration_id' => $deviceRegistrationId,
                'collapse_key' => $msgType,
                'data.message' => $messageText //TODO Add more params with just simple data instead           
            );

            $ch = curl_init();

            curl_setopt($ch, CURLOPT_URL, "https://android.apis.google.com/c2dm/send");
            if ($headers)
            curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_POST, true);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $data);


            $response = curl_exec($ch);

            curl_close($ch);

            return $response;
        }
