当应用程序在 iOS 中处于后台模式时未收到 GCM 通知 [英] GCM Notifications not receiving when app is in background mode in iOS
本文介绍了当应用程序在 iOS 中处于后台模式时未收到 GCM 通知的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经在我现有的应用程序中配置了 GCM，我正在那里接收通知.现在我面临两个问题:1) 当我退出应用程序或应用程序在后台时，我没有收到通知.2) 我没有在 iphone 的通知区域收到通知，只有当我的应用程序运行时，我才直接在那里收到警报消息.当我下拉通知区域时，我在 xcode 的控制台中收到此消息无法连接到 GCM:操作无法完成.(com.google.gcm 错误 2001.)"
I have configured GCM in my existing app and i am receiving the notifications there. Now i am facing two problem: 1) I am not receiving notifications When i exit the application or application is in the background. 2) I am not receiving notification in iphone's notification area, only when my app is running i only direct receive alert message there. And when i pull down notification area i get this message in xcode's console "Could not connect to GCM: The operation couldn’t be completed. (com.google.gcm error 2001.)"
我的 PHP 文件在下面
My PHP file is below
<?php
// Payload data you want to send to iOSdevice(s)
// (it will be accessible via intent extras)
$data = array( 'message' => 'Hello World!');
// The recipient registration tokens for this notification
// http://developer.android.com/google/gcm/
$ids = array( 'kucy6xoUmx********eeRsla' );
// Send a GCM push
sendGoogleCloudMessage( $data, $ids );
function sendGoogleCloudMessage( $data, $ids )
{
// Insert real GCM API key from Google APIs Console
// https://code.google.com/apis/console/
$apiKey = 'AIz******9JA';
// Define URL to GCM endpoint
$url = 'https://gcm-http.googleapis.com/gcm/send';
// Set GCM post variables (device IDs and push payload)
$post = array(
'registration_ids' => $ids,
'data' => $data,
);
// Set CURL request headers (authentication and type)
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
// Initialize curl handle
$ch = curl_init();
// Set URL to GCM endpoint
curl_setopt( $ch, CURLOPT_URL, $url );
// Set request method to POST
curl_setopt( $ch, CURLOPT_POST, true );
// Set our custom 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 push
$result = curl_exec( $ch );
// Error handling
if ( curl_errno( $ch ) )
{
echo 'GCM error: ' . curl_error( $ch );
}
// Close curl handle
curl_close( $ch );
// Debug GCM response
echo $result;
}
?>
这是我的 AppDelegate.m 文件

我不是 php 脚本高手，所以请帮助我解决我的问题.
I am not a php script master so please help me that how i can resolve my issues.
推荐答案
我已添加
'content_available' => true,//to trigger when iOS app is in background
'priority' => 'high',
'notification' => $data,
$data = array( 'message' => 'Hello World!', 'body' => 'Hello World!');
到你的代码.请尝试以下代码；
to your code. Please try below code;
<?php
// Payload data you want to send to iOSdevice(s)
// (it will be accessible via intent extras)
$data = array( 'message' => 'Hello World!', 'body' => 'Hello World!');
// The recipient registration tokens for this notification
// http://developer.android.com/google/gcm/
$ids = array( 'kucy6xoUmx********eeRsla' );
// Send a GCM push
sendGoogleCloudMessage( $data, $ids );
function sendGoogleCloudMessage( $data, $ids )
{
// Insert real GCM API key from Google APIs Console
// https://code.google.com/apis/console/
$apiKey = 'AIz******9JA';
// Define URL to GCM endpoint
$url = 'https://gcm-http.googleapis.com/gcm/send';
// Set GCM post variables (device IDs and push payload)
$post = array(
'registration_ids' => $ids,
'data' => $data,
'content_available' => true,
'priority' => 'high',
'notification' => $data,
);
// Set CURL request headers (authentication and type)
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
// Initialize curl handle
$ch = curl_init();
// Set URL to GCM endpoint
curl_setopt( $ch, CURLOPT_URL, $url );
// Set request method to POST
curl_setopt( $ch, CURLOPT_POST, true );
// Set our custom 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 push
$result = curl_exec( $ch );
// Error handling
if ( curl_errno( $ch ) )
{
echo 'GCM error: ' . curl_error( $ch );
}
// Close curl handle
curl_close( $ch );
// Debug GCM response
echo $result;
}
?>
在IOS端；在 GCM 网站
编辑 1:您可以尝试为 ios 发送通知；
EDIT 1: You may try sending notification for ios;
我在上面编辑了你的 php 代码；变化是;
I edited your php code above; Changes are;
'通知' => $data,
'notification' => $data,
和
$data = array( 'message' => 'Hello World!', 'body' => 'Hello World!');
$data = array( 'message' => 'Hello World!', 'body' => 'Hello World!');
