我正在尝试用PHP为Azure通知中心API创建SharedAccessSignature

我不断收到错误“无效授权令牌签名”

有人举过在PHP5.4+中创建SAS的例子吗? 上有一些API文档,但有人说实现与文档不同

这是我失败的实现:

private static function get_authentication_header()
    {
        $uri = "https://x.servicebus.windows.net/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;
 }

下面是一个简单的包装器,用于使用PHP向通知中心发送通知

<?php

我不知道你是想发送推送还是做注册管理。修改上述内容以进行注册管理并不困难,如NHRESTAPI所示(记住xml文档中的顺序!):

如果你仍然遇到问题,请告诉我


Elio

Hi Elio,使用您的代码,我能够成功连接到通知中心API,在提交推送通知时得到201响应。但是我的所有推送通知都不会发送,而是记录在azure控制面板中的“所有通道错误”指标下。是否也可以包含notification.php文件?可能是我在特定的头上犯了一个错误。嗨,Elio,我在通知中心API上仍然有问题。获取201响应没有问题,但不会发送任何通知。使用调试面板发送通知可以正常工作。所以这一定是我的通知负载或标题的问题。到今天为止,所有的东西似乎都使用相同的代码库,Azure通知中心出现了一些内部问题?推动iOS和Windows Phone,现在做得很好。
