在ASP.NET Web服务中推送Android和iPhone的通知 [英] Push Notification for Android and iPhone in ASP.NET Web Service
问题描述
大家好，
我们如何在ASP.NET Web服务中为Android和iPhone发送推送通知。
我必须遵循的步骤和所有设置是什么？
谢谢
< blockquote>对于Android：
public void Notify（string regId）
{
var applicationID =Application从谷歌帐户生成的ID来到这里;
var result =;
var SENDER_ID =您将从谷歌帐户获得的12位数字;
var httpWebRequest =（HttpWebRequest）WebRequest.Create（https://android.googleapis.com/gcm/send）;
httpWebRequest.ContentType =application / json;
httpWebRequest.Method =POST;
httpWebRequest.Headers.Add（string.Format（Authorization：key = {0}，applicationID））;
httpWebRequest.Headers.Add（string.Format（Sender：key = {0} ，SENDER_ID））;
使用（var streamWriter = new StreamWriter（httpWebRequest.GetRequestStream（）））
{
string json ={ \registration_ids\：[\+ regId +\]，+\data \：{\message \：\您的消息文本将会到来这里...... \}};
Console.WriteLine（json）;
streamWriter.Write（json）;
streamWriter。 Flush（）;
streamWriter.Close（）;
var httpResponse =（HttpWebResponse）httpWebRequest.GetResponse（）;
使用（var streamReader = new StreamReader（httpResponse.GetResponseStream（）））
{
result = streamReader.ReadToEnd（）;
}
}
}
--------------------- -------------------------------------------------- ---------------
For iPhone：
public void pushMessage（string deviceID）
{
int port = 2195;
String hostname =gateway.sandbox.push.apple.com;
String certificatePath = HttpContext.Current.Server.MapPath（CertificateNameCommeshere。 P12\" ）;
X509Certificate2 clientCertificate = new X509Certificate2（System.IO.File.ReadAllBytes（certificatePath），PasswordofCertificateComeshere）;
X509Certificate2Collection certificatesCollection = new X509Certificate2Collection（clientCertificate）;
TcpClient client = new TcpClient（hostname，port）;
SslStream sslStream = new SslStream（client.GetStream（），false，new RemoteCertificateValidationCallback（ValidateServerCertificate） ），null）;
尝试
{
sslStream.AuthenticateAsClient（hostname，certificatesCollection，SslProtocols.Ssl3 ，false）;
MemoryStream memoryStream = new MemoryStream（）;
BinaryWriter writer = new BinaryWriter（memoryStream）;
writer.Write（（字节）0）;
writer.Write（（byte）0）;
writer.Write（（byte）32）;
writer.Write（HexStringToByteArray（deviceID.ToUpper（）））;
String payload ={\aps \：{\alert \：\+你的消息文本会来这里..+\，\\ \\badge \：1，\sound \：\default \}};
writer.Write（（byte）0）;
writer.Write（（byte）payload.Length）;
byte [] b1 = System.Text.Encoding.UTF8.GetBytes（payload）;
writer.Write（b1）;
writer.Flush（）;
byte [] array = memoryStream.ToArray（）;
sslStream。写（数组）;
sslStream.Flush（）;
client.Close（）;
}
catch（System.Security.Authentication.AuthenticationException ex）
{
client.Close（）;
}
catch（例外e）
{
client.Close（）;
}
}
我得到了这些解决方案..
执行上述方法时出现以下错误
System.dll中出现'System.Net.WebException'类型的异常，但未在用户代码中处理
附加信息：远程服务器返回错误：（401）未经授权。
Hi All,
How we can Send Push Notification for Android and iPhone in ASP.NET Web Service.
What are the steps I will have to follow and all settings ?
Thanks
For Android :
public void Notify(string regId)
{
var applicationID = "Application Id generated from google account comes here";
var result = "";
var SENDER_ID = "12 digit id you will get from google account";
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://android.googleapis.com/gcm/send");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
httpWebRequest.Headers.Add(string.Format("Authorization: key={0}", applicationID));
httpWebRequest.Headers.Add(string.Format("Sender: key={0}", SENDER_ID));
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{\"registration_ids\":[\"" + regId + "\"]," + "\"data\": { \"message\" : \"Your Message Text Will Come here..\"}}";
Console.WriteLine(json);
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
}
}

For iPhone :
public void pushMessage(string deviceID)
{
int port = 2195;
String hostname = "gateway.sandbox.push.apple.com";
String certificatePath = HttpContext.Current.Server.MapPath("CertificateNameCommeshere.p12");
X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(certificatePath), "PasswordofCertificateComeshere");
X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate);
TcpClient client = new TcpClient(hostname, port);
SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
try
{
sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Ssl3, false);
MemoryStream memoryStream = new MemoryStream();
BinaryWriter writer = new BinaryWriter(memoryStream);
writer.Write((byte)0);
writer.Write((byte)0);
writer.Write((byte)32);
writer.Write(HexStringToByteArray(deviceID.ToUpper()));
String payload = "{\"aps\":{\"alert\":\"" + "Your Message Text Will Come here.." + "\",\"badge\":1,\"sound\":\"default\"}}";

writer.Write((byte)payload.Length);
byte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload);
writer.Write(b1);
writer.Flush();
byte[] array = memoryStream.ToArray();
sslStream.Write(array);
sslStream.Flush();
client.Close();
}
catch (System.Security.Authentication.AuthenticationException ex)
{
client.Close();
}
catch (Exception e)
{
client.Close();
}
}
I got these solutions..
Getting below error while executing above method
An exception of type 'System.Net.WebException' occurred in System.dll but was not handled in user code
Additional information: The remote server returned an error: (401) Unauthorized.
