这适用于Windows 10的应用程序.
我按照本教程:
https://msdn.microsoft.com/windows/uwp/controls-and-patterns/tiles-and-notifications-windows-push-notification-services–wns–overview
在这一点上,我得到了正确的下一个值:
SID
Secret
Uri(I got this on my application)
我得到的Uri是这个简单的代码:
channel=await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();
通过上面的这一行,我得到了一个大约一个月有用的网址.
我现在无法做的部分是将推送通知发送到应用程序.
关于如何使用Uri以及如何将信息发送给它的任何指示我都会很高兴,因为我有400错误,这与我的帖子消息有关.
此链接显示如何发送信息,但我没有得到任何有用的代码.

也:
我不拥有或使用任何基于云的Web服务.
我可以在发布或调试模式下获得推送通知吗?
使用正确的Uri推送通知可以用PHP完成吗?
解决方法:
刚刚完成Jerrak0s的解决方案
使用REST发送推送通知的代码:
private static async void SendNotificationAsync()
{
//Setting\Access policies\DefaultFullSharedAccessSignature policy
string connStr = "Endpoint=sb://[namespace].servicebus.windows.net/;SharedAccessKeyName=DefaultFullSharedAccessSignature;SharedAccessKey=xyz";
var util = new ConnectionStringUtility(connStr);
//toast in XML
var toast = "<toast> <visual>
<binding template="ToastText01">
< text id = "1" > Test message </ text >
</ binding > </ visual > </ toast >";
//call WNS
var uri = "https://[namespace].servicebus.windows.net/[hub name]/messages/?api-version=2015-04";
using (var httpClient = new HttpClient())
{
var request = new HttpRequestMessage(HttpMethod.Post, uri);
request.Content = new StringContent(toast);
request.Headers.Add("Authorization", util.getSaSToken(uri, 1000));
//request.Headers.Add("ServiceBusNotification-Tags", "TAG");
request.Headers.Add("ServiceBusNotification-Format", "windows");
request.Headers.Add("X-WNS-Type", "wns/toast");
var response = await httpClient.SendAsync(request);
await response.Content.ReadAsStringAsync();
}
}
用于解析端点和SAS令牌的Utility类:
public class ConnectionStringUtility
{
public string Endpoint { get; private set; }
public string SasKeyName { get; private set; }
public string SasKeyValue { get; private set; }
public ConnectionStringUtility(string connectionString)
{
//Parse Connectionstring
char[] separator = { ';' };
string[] parts = connectionString.Split(separator);
for (int i = 0; i < parts.Length; i++)
{
if (parts[i].StartsWith("Endpoint"))
Endpoint = "https" + parts[i].Substring(11);
if (parts[i].StartsWith("SharedAccessKeyName"))
SasKeyName = parts[i].Substring(20);
if (parts[i].StartsWith("SharedAccessKey"))
SasKeyValue = parts[i].Substring(16);
}
}
public string getSaSToken(string uri, int minUntilExpire)
{
string targetUri = Uri.EscapeDataString(uri.ToLower()).ToLower();
// Add an expiration in seconds to it.
long expiresOnDate = DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond;
expiresOnDate += minUntilExpire * 60 * 1000;
long expires_seconds = expiresOnDate / 1000;
String toSign = targetUri + "\n" + expires_seconds;
// Generate a HMAC-SHA256 hash or the uri and expiration using your secret key.
MacAlgorithmProvider macAlgorithmProvider = MacAlgorithmProvider.OpenAlgorithm(MacAlgorithmNames.HmacSha256);
BinaryStringEncoding encoding = BinaryStringEncoding.Utf8;
var messageBuffer = CryptographicBuffer.ConvertStringToBinary(toSign, encoding);
IBuffer keyBuffer = CryptographicBuffer.ConvertStringToBinary(SasKeyValue, encoding);
CryptographicKey hmacKey = macAlgorithmProvider.CreateKey(keyBuffer);
IBuffer signedMessage = CryptographicEngine.Sign(hmacKey, messageBuffer);
string signature = Uri.EscapeDataString(CryptographicBuffer.EncodeToBase64String(signedMessage));
return "SharedAccessSignature sr=" + targetUri + "&sig=" + signature + "&se=" + expires_seconds + "&skn=" + SasKeyName;
}
}
