iOS推送通知发送错误

Question

我是一名 iOS 应用程序开发人员，对 php 了解不多。我正在关注raywenderlich push notification tutorial 为推送通知生成 SSL 证书和私钥。

我按照这些步骤操作了 3-4 次，但它不起作用。我之前也按照相同的步骤进行操作。

我认为问题在于我在测试使用 SSL 证书连接到 APNS 服务器时得到的响应。我得到以下回应。

在响应开始时，它给出错误verify error:num=20:unable to get local issuer certificate。在回复的后半部分还写着No client certificate CA names sent。 我不知道这些事情，但我怀疑问题出在这些错误上。

编辑：使用教程中提供的示例 php 脚本发送通知时出错。

Warning: stream_socket_client(): Unable to set private key file `/Users/akashpatel/Desktop/SimplePush/ck.pem' in /Users/akashpatel/Desktop/SimplePush/simplepush.php on line 25

Warning: stream_socket_client(): failed to create an SSL handle in /Users/akashpatel/Desktop/SimplePush/simplepush.php on line 25

编辑： 使用这个app（segev 在他的回答中建议）我测试了证书/私钥是否有任何问题。我可以成功收到通知。所以我想问题不在于证书/私钥。

我正在使用的 PHP 脚本：

<?php

$deviceToken = 'r34f34f5g45g5y56u76hj676elfjn4urno43f958gh945g8g7';

// Put your private key's passphrase here:
$passphrase = ‘pasphrase’;

// Put your alert message here:
$message = 'Received push notification!';

////////////////////////////////////////////////////////////////////////////////

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

// Open a connection to the APNS server
$fp = stream_socket_client(
    'ssl://gateway.sandbox.push.apple.com:2195', $err,
    $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

if (!$fp)
    exit("Failed to connect: $err $errstr" . PHP_EOL);

echo 'Connected to APNS' . PHP_EOL;

// Create the payload body
$body['aps'] = array(
    'alert' => $message,
    'sound' => 'default'
    );

// Encode the payload as JSON
$payload = json_encode($body);

// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));

if (!$result)
    echo 'Message not delivered' . PHP_EOL;
else
    echo 'Message successfully delivered' . PHP_EOL;

// Close the connection to the server
fclose($fp);

编辑：我的脚本在生产服务器中使用时可以工作。但是我会保持这个问题的开放，因为它在本地服务器中不起作用。建议可能会帮助其他在生产服务器中不起作用的人。

Answer 1

当我使用我在本地服务器上遵循的教程提供的 PHP 脚本进行测试时，我不知道出现了什么问题。但是当我使用生产服务器进行测试时，它正在发送通知。

Answer 2

查看错误：

CONNECTED(00000003) 深度=1 /C=US/O=委托， Inc./OU=www.entrust.net/rpa 通过引用并入/OU=(c) 2009 Entrust, Inc./CN=Entrust 证书颁发机构 - L1C 验证 error:num=20:unable to get local issuer certificate verify return:0

看看你如何设置应用上下文到流选项：

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

我使用与您相同的教程，在故障排除部分阅读项目符号 #3

无法获取本地颁发者证书。这个错误意味着 无法验证来自服务器的证书。要解决这个问题，你 需要下载 Entrust CA 根证书。这可以做到 从终端使用命令： curl -O https://www.entrust.net/downloads/binary/entrust_2048_ca.cer那你 还需要添加stream_context_set_option($ctx, 'ssl', 'cafile', 'entrust_2048_ca.cer');

下载entrust_2048_ca.cer

确保您的所有证书与 PHP 脚本位于同一目录中。

将您的代码更改为以下内容：

//applying context to stream option
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
stream_context_set_option($ctx, 'ssl', 'cafile', 'entrust_2048_ca.cer');

你现在应该很好了。

Answer 3

推送通知有很多问题，您需要一一解决。

暂时忘记 php 代码。 转到here 并下载最新版本。

这是一个很棒的小型应用程序，它为您完成所有服务器端，并将向您的设备发送推送通知。如果可行，您可以继续执行 php 代码，但我怀疑您的问题出在应用证书 \ 密钥上。
