Azure的通知集线器REST API与PHP

本文介绍了Azure的通知集线器REST API与PHP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

我试图创建在PHP中的Azure通知集线器API一个SharedAccessSignature。

我不断收到错误无效授权令牌的签名。

任何人有创造PHP 5.4+的SAS的例子吗？有对API的一些文档： msdn.microsoft/ EN-US /库/ dn170477.aspx 的，但有些人说，从执行的文件是不同的。

这是我失败的实现：

私有静态函数get_authentication_header（）    {        $ URI =htt​​ps://x.servicebus.windows/x;        $ =到期时间（）+（60 * 60）;        $字符串= utf8_en code（urlen code（$ URI）\\ n$到期）;        $键名=DefaultFullSharedAccessSignature;        $键= base64_de code（静态:: HUB_KEY）;        $签名= base64_en code（hash_hmac（'SHA256'，$字符串，$键））;        $ SAS ='SharedAccessSignature SIG ='。 $签名。 '和; SE ='。 $到期。 '和; SKN ='。 $键名。 '和; SR ='。 urlen code（$ URI）;        返回$ SAS; }

解决方案

下面是一个简单的包装将通知发送给通知集线器用PHP。

我不知道，如果你想发送推送或做登记管理。不难修改上面的做登记管理如图所示的NH REST API的（记得在XML文档事项的顺序！）的 msdn.microsoft/en-us/library/dn223264.aspx 。

让我知道如果你仍然遇到问题。

I'm trying to create a SharedAccessSignature for the Azure Notifications Hubs API in PHP.

I keep getting the error "Invalid authorization token signature".

Anyone has an example of creating the SAS in PHP 5.4+? There is some documentation of the API on: msdn.microsoft/en-us/library/dn170477.aspx, but some people say that the implementation differs from the documentation.

This is my failing implementation:

private static function get_authentication_header() { $uri = "x.servicebus.windows/x"; $expiry = time() + (60*60); $string = utf8_encode(urlencode($uri) . "\n" . $expiry); $keyname = "DefaultFullSharedAccessSignature"; $key = base64_decode(static::HUB_KEY); $signature = base64_encode(hash_hmac('sha256', $string, $key)); $sas = 'SharedAccessSignature sig=' . $signature . '&se=' . $expiry . '&skn=' . $keyname . '&sr=' . urlencode($uri); return $sas; }

解决方案

Here is a simple wrapper to send notifications to Notification Hubs with PHP.

<?php include 'Notification.php'; class NotificationHub { const API_VERSION = "?api-version=2013-10"; private $endpoint; private $hubPath; private $sasKeyName; private $sasKeyValue; function __construct($connectionString, $hubPath) { $this->hubPath = $hubPath; $this->parseConnectionString($connectionString); } private function parseConnectionString($connectionString) { $parts = explode(";", $connectionString); if (sizeof($parts) != 3) { throw new Exception("Error parsing connection string: " . $connectionString); } foreach ($parts as $part) { if (strpos($part, "Endpoint") === 0) { $this->endpoint = "https" . substr($part, 11); } else if (strpos($part, "SharedAccessKeyName") === 0) { $this->sasKeyName = substr($part, 20); } else if (strpos($part, "SharedAccessKey") === 0) { $this->sasKeyValue = substr($part, 16); } } } private function generateSasToken($uri) { $targetUri = strtolower(rawurlencode(strtolower($uri))); $expires = time(); $expiresInMins = 60; $expires = $expires + $expiresInMins * 60; $toSign = $targetUri . "\n" . $expires; $signature = rawurlencode(base64_encode(hash_hmac('sha256', $toSign, $this->sasKeyValue, TRUE))); $token = "SharedAccessSignature sr=" . $targetUri . "&sig=" . $signature . "&se=" . $expires . "&skn=" . $this->sasKeyName; return $token; } public function broadcastNotification($notification) { $this->sendNotification($notification, ""); } public function sendNotification($notification, $tagsOrTagExpression) { echo $tagsOrTagExpression."<p>"; if (is_array($tagsOrTagExpression)) { $tagExpression = implode(" || ", $tagsOrTagExpression); } else { $tagExpression = $tagsOrTagExpression; } # build uri $uri = $this->endpoint . $this->hubPath . "/messages" . NotificationHub::API_VERSION; echo $uri."<p>"; $ch = curl_init($uri); if (in_array($notification->format, ["template", "apple", "gcm"])) { $contentType = "application/json"; } else { $contentType = "application/xml"; } $token = $this->generateSasToken($uri); $headers = [ 'Authorization: '.$token, 'Content-Type: '.$contentType, 'ServiceBusNotification-Format: '.$notification->format ]; if ("" !== $tagExpression) { $headers[] = 'ServiceBusNotification-Tags: '.$tagExpression; } # add headers for other platforms if (is_array($notification->headers)) { $headers = array_merge($headers, $notification->headers); } curl_setopt_array($ch, array( CURLOPT_POST => TRUE, CURLOPT_RETURNTRANSFER => TRUE, CURLOPT_SSL_VERIFYPEER => FALSE, CURLOPT_HTTPHEADER => $headers, CURLOPT_POSTFIELDS => $notification->payload )); // Send the request $response = curl_exec($ch); // Check for errors if($response === FALSE){ throw new Exception(curl_error($ch)); } $info = curl_getinfo($ch); if ($info['http_code'] <> 201) { throw new Exception('Error sending notificaiton: '. $info['http_code'] . ' msg: ' . $response); } //print_r($info); //echo $response; } } ?>

I do not know if you wanted to send pushes or to do registration management. It is not hard to modify the above to do registration management as shown in the NH REST APIs (remember the order in the xml documents matters!): msdn.microsoft/en-us/library/dn223264.aspx.

Let me know if you still run into problems.
