GoogleCloudMessaging PHP脚本总是返回invalidregistration [英] GoogleCloudMessaging PHP script always returning invalidregistration

问题描述

我知道有很多有相同问题的帖子，但阅读所有这些后，我无法找到问题的原因。

我写了一个GCM客户登记自己的设备从我的服务器接收邮件。这是工作，我可以存储在我的数据库中的注册ID。

我的问题是在服务器端。我用在什么地方找到谷歌搜索的脚本，但我总是收到一个错误的结果：

<$p$p><$c$c>{"multicast_id":7341760174206782539,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}

PHP的code是（我使用的浏览器的API，而不是服务器API如告诉在教程中，但在尝试这两个键返回相同的消息）：

 ＆LT; PHP
//替换为来自谷歌的API真正的浏览器的API密钥
$ apiKey =AIzaSyACln4edhSZW30XcmYpqoMz_gcRCC1iFjY;

//替换为真正的客户端注册的ID
$ registrationIDs =阵列（ "APA91bEdf1w4dQtsUqPT1jHhWEpvrpxzB1yrpL3RVtKrVxfzxfg2-Yl-pwHorsnmSnkqywQ8G90YcGEBoqCjgQU8CnjA0N7mOWF8bHMhHAs4ty46PPTX8yh6eSaSqvU3JTMmb-P0ma90EBG0rsQQbUh3aX895KxitI3LCiGOYqRfE5pZQ");

//消息要发送
$消息=这是一个测试;

//设置POST变量
$ URL ='https://android.googleapis.com/gcm/send';

$领域=阵列（
                registration_ids'=＆GT; $ registrationIDs，
                '数据'=＆GT;阵列（信息=＆GT; $消息）
                ）;

$标题=阵列（
                    授权：键='。 $ apiKey，
                    内容类型：应用程序/ JSON
                ）;

//打开连接
$ CH = curl_init（）;

//设置URL，POST数瓦尔，POST数据
curl_setopt（$ CH，CURLOPT_URL，$网址）;

curl_setopt（$ CH，CURLOPT_POST，真正的）;
curl_setopt（$ CH，CURLOPT_HTTPHEADER，$头）;
curl_setopt（$ CH，CURLOPT_RETURNTRANSFER，真正的）;

curl_setopt（$ CH，CURLOPT_POSTFIELDS，json_en code（$域））;

//执行后
$结果= curl_exec（$ CH）;

//关闭连接
curl_close（$ CH）;

回声$结果;
？＆GT;
 

我把真实的ID和关键，看看我做的事情。任何想法？

解决方案

我发现我的问题。我的PHP库移出后某些字符或GET变量。和该characteres一个是_，因为它可以用作SQL注入。这是我的问题。修正了！

I know there are lots of posts with the same issue, but after read all of them I could not find the reason of the problem.

I wrote a GCM client to register my device to receive messages from my server. It is working and I can store the registration ID in my database.

My problem is in the server side. I'm using a script found somewhere googling, but I always receive an error result:

{"multicast_id":7341760174206782539,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}

The PHP code is (I'm using BROWSER API instead of SERVER API as told on tutorial, but trying both keys returns the same message):

<?php
// Replace with real BROWSER API key from Google APIs
$apiKey = "AIzaSyACln4edhSZW30XcmYpqoMz_gcRCC1iFjY";

// Replace with real client registration IDs 
$registrationIDs = array( "APA91bEdf1w4dQtsUqPT1jHhWEpvrpxzB1yrpL3RVtKrVxfzxfg2-Yl-pwHorsnmSnkqywQ8G90YcGEBoqCjgQU8CnjA0N7mOWF8bHMhHAs4ty46PPTX8yh6eSaSqvU3JTMmb-P0ma90EBG0rsQQbUh3aX895KxitI3LCiGOYqRfE5pZQ");

// Message to be sent
$message = "this is a test";

// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';

$fields = array(
                'registration_ids'  => $registrationIDs,
                'data'              => array( "message" => $message ),
                );

$headers = array( 
                    'Authorization: key=' . $apiKey,
                    'Content-Type: application/json'
                );

// Open connection
$ch = curl_init();

// Set the url, number of POST vars, POST data
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_POSTFIELDS, json_encode( $fields ) );

// Execute post
$result = curl_exec($ch);

// Close connection
curl_close($ch);

echo $result;
?>

I put the real ids and key to see if I'm doing right. Any ideas?

解决方案

I found my problem. My PHP library removed some characters from post or get variables. And one of that characteres is '_', because it can be use as SQL injection. That was my problem. Fixed!
