Question

我在链接https://developers.google.com/cloud-messaging/android/client中跟踪了“快速启动示例”和google云消息最新版本的说明，并从此说明下载项目。我成功获得设备的令牌，我有一个PHP服务器发送到谷歌云，但我无法从我的设备收到消息。你能帮我吗？

我从此网站下载项目，建议在上面的链接中

$ git clone https://github.com/googlesamples/google-services.git

以下是我的服务器代码

gcm.php

 // Payload data you want to send to Android device(s)
        // (it will be accessible via intent extras)    
        $data = array('message' => 'Hello World!');

        // Send push notification via Google Cloud Messaging
        sendPushNotification($data, $ids);

        function sendPushNotification($data, $ids)
        {
            // Insert real GCM API key from the Google APIs Console

            // Set CURL request headers 
            $headers = array(

                            );

            // Initialize curl handle

            // Set request method to POST       
            curl_setopt($ch, CURLOPT_POST, true);

            // Set custom request headers       
            curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

            // Get the response back as string instead of printing it       
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

            // Set JSON post data
            curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post));

            // Actually send the request    
            $result = curl_exec($ch);

            // Handle errors
            if (curl_errno($ch))
            {
                echo 'GCM error: ' . curl_error($ch);
            }

            // Close curl handle
            curl_close($ch);

            // Debug GCM response       
            echo $result;


        }

我从服务器收到了消息：

我用Google搜索了很多教程，博客但我的设备仍然无法获取消息。我错过了什么吗？我的网络很好，因为我可以打开网页。

已解决：我更改为firebase云消息并且它正常工作。感谢所有朋友在这里帮助我。

尝试以下解决方法：

确保您已正确设置自Google收到的SENDER ID。
确保您的设备已正确注册Google的GCM服务。
确保您将推送发送到您从Google收到的正确注册码。并且您没有从Google GCM服务收到错误。
如果您希望获得wakelock权限，则将其更改为delay_while_idle = 0。如果设置为delay_while_idle = 1，则如果设备处于空闲状态，则该消息无法到达设备。
有时候推送到达需要时间（但从来没有太多时间，那就有问题）。检查＆＃34;生存时间＆＃34;你发送的推文。

您还可以查看以下相关问题：

Can't receive messages using Google Cloud Messaging for Android (not the helper library)
can't receive messages on device using GCM

为了最大化接收消息的机会，我不会将time_to_live设置为仅仅3秒。我完全省略了这个参数，因此默认值为4周。我还将delay_while设置为false，这样即使在空闲时手机也会收到消息。
