我正在安卓中实现推送通知。我已经在安卓中正确实现了客户端编码。它工作正常，并且已经创建了谷歌API密钥。问题：但是当我从服务器发送推送通知时（此脚本是用 php 编写的），然后出现错误。错误是这样的——
{"multicast_id":8690314483687932029,"success":0,"failure":1,"canonical_ids":0,"results": [{"error":"InvalidRegistration"}]}
我的服务器端脚本是这样的。
<?php
//Generic php function to send GCM push notification
function sendMessageThroughGCM($registatoin_ids, $message) {
//Google cloud messaging GCM-API url
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
);
// Update your Google Cloud Messaging API Key
define("GOOGLE_API_KEY", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
$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;
}
?>
<?php
//Post message to GCM when submitted
$pushStatus = "GCM Status Message will appear here";
if(!empty($_GET["push"])) {
$gcmRegID = file_get_contents("GCMRegId.txt");
$pushMessage = $_POST["message"];
if (isset($gcmRegID) && isset($pushMessage)) {
$gcmRegIds = array($gcmRegID);
$message = array("m" => $pushMessage);
$pushStatus = sendMessageThroughGCM($gcmRegIds, $message);
}
}
//Get Reg ID sent from Android App and store it in text file
if(!empty($_GET["shareRegId"])) {
$gcmRegID = $_POST["regId"];
file_put_contents("GCMRegId.txt",$gcmRegID);
echo "Done!";
exit;
}
?>

我是安卓新手。我无法找到确切的问题。请帮助我，提前谢谢。
在你的路径中改变它
action="/gcm/gcm.php/?push=true"
自
action="test/gcm/gcm.php/?push=true"
这里 test 是服务器上的文件夹，GCM 是一个子文件夹。 GCM.php 应该放在子文件夹中。
