我对GCM / Java还不熟悉,虽然有php经验,但只是mysql方面的。
这篇文章非常有用,我成功地使它工作了。我的唯一问题是这段代码只能向一个设备发送。 我尝试编辑它,让它使用一个表单和一个提交按钮向多个设备发送,但没有成功。
这段代码从Java(客户端)获取信息,并使用php(服务器)将其放入mysql数据库中。 它还在mysql DB中注册设备的GCM注册ID,然后您可以通过id的GCM注册ID向设备发送通知。
这里是index.php,您可以在其中填写表单:

$(document).ready(function(){
});
function sendPushNotification(id){
var data = $('form#'+id).serialize();
$('form#'+id).unbind('submit');
$.ajax({
url: "send_message.php",
type: 'GET',
data: data,
beforeSend: function() {

success: function(data, textStatus, xhr) {
$('.txt_message').val("");

return false;

使用Ajax将信息发送到GCM:
Send_message.php:
<?php
if (isset($_GET['regId']) && (isset($_GET["message"]))) {
$regId = $_GET['regId'];
$message = $_GET["message"];
include_once './GCM.php';
$gcm = new GCM();
$registatoin_ids = array($regId);
$message = array("price" => $message);
$result = $gcm->send_notification($registatoin_ids, $message);
echo $result;
}
?>
如您所见,它通过id获取所有内容,但我想使用一个表单、一个提交按钮和一个文本字段向多个设备发送。
如果有人能指导我如何做或给我一些示例,我将不胜感激。
