如何使用带有PHP的azure集线器向一些用户发送批量推送通知（示例）

Question

我在https://docs.microsoft.com/en-us/previous-versions/azure/reference/mt734910(v%3dazure.100)中找到了“直接批量发送”的示例，但是我不知道如何使用PHP。

我已成功通过PHP请求“直接发送” API。但是我不知道如何使用“直接批量发送” API

有“直接发送” API请求功能

public function sendNotification($notification, $tagsOrTagExpression="") {
        if (is_array($tagsOrTagExpression)) {
            $tagExpression = implode(" || ", $tagsOrTagExpression);
        } else {
            $tagExpression = $tagsOrTagExpression;
        }

        # build uri
        $uri = $this->endpoint . $this->hubPath . "/messages" . NotificationHub::API_VERSION;
//        $uri = $this->endpoint . $this->hubPath . "/messages/$batch?direct$" . NotificationHub::API_VERSION;
        $ch = curl_init($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);

        var_dump($info);
        var_dump($response);
        if ($info['http_code'] <> 201) {
            throw new Exception('Error sending notification: '. $info['http_code'] . ' msg: ' . $response);
        }
    }
