我正在使用amazon PHP SDK V3.13.1，我必须在30秒内发送至少10,000次推送通知。现在我正在使用publishAsync方法它更快，但我仍然没有及时发送它
所以我有实现套接字并且每次都发送一堆3500推送。以下是我发送套接字请求的控制器功能。
$parts = parse_url(base_url() . "welcome/send_signal");
for ($i = 1; $i <= 10000; $i++) {
$device_type_ids_arr[$i]['token_id'] = "User token";
$device_type_ids_arr[$i]['arn'] = "User arn";
$device_type_ids_arr[$i]['member_id'] = $i;
if ((count($device_type_ids_arr) == 3500) || $i == 10000) {
$postData['devices'] = $device_type_ids_arr;
$postData['pushSet'] = $pushSet;
$postData['push_content'] = $push_content;
$post_string = http_build_query($postData);
$device_type_ids_arr = array();
$fp = fsockopen($parts['host'], isset($parts['port']) ? $parts['port'] : 80, $errno, $errstr, 600);
if (!$fp) {
echo "Some thing Problem";
}
$out = "POST " . $parts['path'] . " HTTP/1.1\r\n";
$out .= "Host: " . $parts['host'] . "\r\n";
$out .= "User-Agent: " . $_SERVER['HTTP_USER_AGENT'] . "\r\n";
$out .= "Content-Type: application/x-www-form-urlencoded\r\n";
$out .= "Content-Length: " . strlen($post_string) . "\r\n";
$out .= "Connection: Close\r\n\r\n";
$out .= $post_string;
fwrite($fp, $out);
fclose($fp);
}
}
以下是我的函数，它接收套接字数据并发送推送通知。
$sns = new Aws\Sns\SnsClient(array(
'version' => 'latest',
'key' => "my sns key",
'secret' => "secret",
'region' => "region",
'profile' => "amazon_user_profile",
'debug' => false,
'http' => array('verify' => false)
));
foreach ($device_id_arr as $device_detail) {
try {
$promises[] = $sns->publishAsync(array(
'Message' => '{ "GCM": "{\"data\": { \"message\": \"Hello user\" } }"}',
'MessageStructure' => 'json',
'TargetArn' => "member sns arn"
));
} catch (Exception $e) {
$errorMsg = $e->getMessage();
}
}
$results = \GuzzleHttp\Promise\settle($promises)->wait(TRUE);
$fp = fopen("test_parallel.txt", "a+");
fwrite($fp, "result:" . print_r($results, true) . "\r\n");
fclose($fp);
当我发送10通知时，这工作正常，但是当我发送3500推送时，它不起作用，并没有给我任何回复。我也尝试过这种方法。 Amazon AWS PHP SDK with Guzzle's MultiCurl?但它给了我错误Argument 1 passed to Aws\AwsClient::execute() must implement interface Aws\CommandInterface, array given
$sns = new Aws\Sns\SnsClient(array(
'version' => 'latest',
'key' => "my sns key",
'secret' => "secret",
'region' => "region",
'profile' => "amazon_user_profile",
'debug' => false,
'http' => array('verify' => false)
));
foreach ($device_id_arr as $device_detail) {
try {
$publishCommands[] = $sns->getCommand('Publish', array(
"Message" => '{ "GCM": "{\"data\": { \"message\": \"' . $push_content . '\", \"type\": \"' . PUSH_TYPE_SIGNAL . '\" } }"}',
"MessageStructure" => "json",
"TargetArn" => $device_detail['arn']
));
} catch (Exception $e) {
$errorMsg = $e->getMessage();
}
}
try {
$successfulCommands = $sns->execute($publishCommands);
$failedCommands = array();
} catch (\Guzzle\Service\Exception\CommandTransferException $e) {
$successfulCommands = $e->getSuccessfulCommands();
$failedCommands = $e->getFailedCommands();
}
foreach ($failedCommands as $failedCommand) {
$fp = fopen("test_parallel4.txt", "a+");
fwrite($fp, "result:" . print_r($result, true) . "\r\n");
fclose($fp);
}
$messageIds = array();
foreach ($successfulCommands as $successfulCommand) {
$messageIds[] = $successfulCommand->getResult()->get('MessageId');
}
所以任何人都有解决方案吗？我主要担心的是在30秒内发送数千个推送通知。
答案 0 :(得分：0)
最后，我使用multiple curl in php获得了解决方案。这是并行执行的，这也取决于您的服务器和Internet速度。以下是我的controller功能。
public function index() {
for ($i = 1; $i <= 10000; $i++) {
$device_type_ids_arr[$i]['member_id'] = $i;
$device_type_ids_arr[$i]['arn'] = "member arn or empty";
$device_type_ids_arr[$i]['token_id'] = "member token";
}
$start = microtime(true);
/* Chunk members into 500 bunch and crete multiple curl request */
$_datas = array_chunk($device_type_ids_arr, 500);
$mh = curl_multi_init();
$handles = array();
foreach ($_datas as $batchPart) {
$ch = curl_init();
$postData['devices'] = $batchPart; //device array
$postData['push_content'] = "Push Message";
$data_string = json_encode($postData);
curl_setopt($ch, CURLOPT_URL, base_url() . "Welcome/send_push_notification");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_USERAGENT, 'User-Agent: curl/7.39.0');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
curl_multi_add_handle($mh, $ch);
$handles[] = $ch;
}
// execute requests and poll periodically until all have completed
$isRunning = null;
do {
curl_multi_exec($mh, $isRunning);
usleep(250000);
} while ($isRunning > 0);
curl_multi_close($mh);
printf("Elapsed time: %.2f seconds\n", microtime(true) - $start);
}
以下是一个并行发送推送通知的功能。我还解释了如何处理Exception并确保将通知发送给所有/最多用户。
public function send_push_notification() {
require_once APPPATH . 'libraries/aws-sdk/aws-autoloader.php';
$pipeArr = json_decode(file_get_contents('php://input'), true);
$push_content = $pipeArr["push_content"];
$device_id_arr = $pipeArr["devices"];
$sns = new Aws\Sns\SnsClient(array(
'version' => 'latest',
'key' => "Amazon account key",
'secret' => "Amazon account secret",
'region' => "Region",
'profile' => "Amazon account user profile",
'debug' => false,
'http' => array('verify' => false)
));
$appArn = "Application Arn";
$promises = $results = $retArr = array();
//start sending loop of 500 members asynchroniously
foreach ($device_id_arr as $key => $device_detail) {
$arn = $device_detail['arn'];
$token = $device_detail['token_id'];
$userid = $device_detail['member_id'];
//If member arn is empty then register it on amazon and then update into databse
if (empty($arn)) {
try {
$updatedArn = $sns->createPlatformEndpoint(array('PlatformApplicationArn' => $appArn, 'Token' => $token));
$arn = isset($updatedArn['EndpointArn']) ? $updatedArn['EndpointArn'] : "";
//update member detail with new arn into database
($arn != "") ?/* DB query goes here */ : "";
} catch (Exception $e) {
$errorMsg = $e->getMessage();
}
}
if (!empty($arn)) {

$promises[$userid]->arn = $arn;
$promises[$userid]->token = $token;
} catch (Exception $e) {
$errorMsg = $e->getMessage();
}
}
}
//This is Async method to send push and get result of each member with message Id
$results = \GuzzleHttp\Promise\settle($promises)->wait(TRUE);
/* Handle result and get message Id */
foreach ($results as $key => $value) {
/* If any of push notification is fail then check for error and fix it */
if (isset($value['reason'])) {
$message = $value['reason']->getMessage();
$token = (isset($promises[$key]->token)) ? $promises[$key]->token : "";
$arn = (isset($promises[$key]->arn)) ? $promises[$key]->arn : "";
if (strpos($message, "Endpoint is disabled") !== false && $token != "" && $arn != "") {
try {
$res = $sns->setEndpointAttributes(array(
'Attributes' => array("Token" => $promises[$key]->token, "Enabled" => "true"),
'EndpointArn' => $arn
));
} catch (Exception $e) {
$errorMsg = $e->getMessage();
}
}
if (strpos($message, "No endpoint found for the target arn specified") !== false && $token != "") {
try {
$updatedArn = $sns->createPlatformEndpoint(array('PlatformApplicationArn' => $appArn, 'Token' => $token));
$arn = isset($updatedArn['EndpointArn']) ? $updatedArn['EndpointArn'] : "";
//update member detail with new arn into database
($arn != "") ?/* DB query goes here */ : "";
} catch (Exception $e) {
$errorMsg = $e->getMessage();
}
}
if (!empty($arn)) {
try {
$publishRes = $sns->publish(array(
'Message' => '{ "GCM": "{\"data\": { \"message\": \"' . $push_content . '\", \"type\": \"' . PUSH_TYPE_SIGNAL . '\" } }"}',
'MessageStructure' => 'json',

));
$retArr[$key] = $publishRes->get("MessageId");
} catch (Exception $e) {
$errorMsg = $e->getMessage();
/* Final error of push notification not sent */
$newFile = fopen("error_push_not_sent.txt", "a+");
fwrite($newFile, "Member Id:" . $key . "\r\nARN:" . $arn . "\r\nToken:" . $token . "\r\n" . $errorMsg . "\r\n");
fclose($newFile);
}
}
} else {
$retArr[$key] = $results[$key]['value']->get("MessageId");
}
}
/* Get message Id of amazon and insert record into database */
if (isset($retArr) && !empty($retArr)) {
foreach ($retArr as $member_id => $message_id) {
/* DB query goes here OR you can generate batch query here and then execute */
}
}
}
