我一直在尝试向模拟器发送Toast通知。

我创建了Windows Phone 8.1应用程序，并将其与商店中的应用程序关联。

之后，我设法获取必须使用的访问令牌来调用通道URI。

当我尝试使用通道URI和访问令牌发送Toast Notification时，出现此错误。

Bearer error="invalid_request",error_description="Invalid token"这是我创建的php测试代码。

//GET ACCESS TOKEN

$tokenRequest = curl_init();

curl_setopt($tokenRequest, CURLOPT_URL, 'https://login.live.com/accesstoken.srf');

curl_setopt($tokenRequest, CURLOPT_HTTPHEADER, array(

'Content-Type: application/x-www-form-urlencoded'

));

//FIELDS

$fields = array(

'grant_type' => 'client_credentials',

'client_id' => '0',

'client_secret' => 'Q',

'scope' => 'notify.windows.com'

);

$fields_string = "";

foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }

rtrim($fields_string, '&');

curl_setopt($tokenRequest, CURLOPT_RETURNTRANSFER, true);

curl_setopt($tokenRequest,CURLOPT_POST, count($fields));

curl_setopt($tokenRequest,CURLOPT_POSTFIELDS, $fields_string);

$output = json_decode(curl_exec($tokenRequest));

curl_close($tokenRequest);

echo "
";

var_dump($output);

echo "
";

$accessToken = $output->{'access_token'};

//SEND PUSH

$sendPush = curl_init();

curl_setopt($sendPush, CURLOPT_URL, 'https://db3.notify.windows.com/?token=AwYAAABuWLaYT1f9BVJwNJCjc243U1OFXUT8MCqvsME%2ftDnhPG%2f%2fJSurxP3u1y47eqmrQZSPUlZH7koHW3Zwdj5938LYZNRdDyE6JzvyHOZvZvSo%3d');

//TOAST MESSAGE

$toastMessage = "" .

"" .

"" . "SendToast" . "" .

"" . "Text Message" . "" .

" " .

"";

curl_setopt($sendPush, CURLOPT_HEADER, true);

$headers = array('Content-Type: text/xml', "Content-Length: " . strlen($toastMessage), "X-WNS-Type: wns/toast", "Authorization: Bearer $accessToken");

curl_setopt($sendPush, CURLOPT_HTTPHEADER, $headers);

curl_setopt($sendPush, CURLOPT_RETURNTRANSFER, true);

curl_setopt($sendPush,CURLOPT_POST, 1);

curl_setopt($sendPush, CURLOPT_POSTFIELDS, $toastMessage);

$output = curl_exec($sendPush);

echo "
";

var_dump(curl_getinfo($sendPush, CURLINFO_HTTP_CODE));

echo "
";

var_dump(curl_getinfo($sendPush, CURLINFO_HEADER_OUT));

echo "
";

var_dump($output);

curl_close($sendPush);

// Create request to send

?>在c#中，我使用它来获取通道URI。

channel = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();

Debug.WriteLine(channel.Uri);任何想法可能会导致这个问题？
