我在 Google Cloud Messaging (GCM) 中创建了一个应用程序，他们给了我：
- 发件人ID
- API-KEY
我已经创建了一个 Android 应用程序，客户可以使用它来将他们的设备注册
到云中......（没关系）。
现在，如果任何使用我的 Android 应用程序的用户更改数据中的某些内容 (SQL SERVER DATABASE)，我想向其余设备推送通知。
我发现这个代码...
private string SendGCMNotification(string apiKey, string postData, string postDataContentType = "application/json")
{
ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateServerCertificate);
//
// MESSAGE CONTENT
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
//
// CREATE REQUEST
HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://android.googleapis.com/gcm/send");
Request.Method = "POST";
Request.KeepAlive = false;
Request.ContentType = postDataContentType;
Request.Headers.Add(string.Format("Authorization: key={0}", apiKey));
Request.ContentLength = byteArray.Length;
Stream dataStream = Request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
//
// SEND MESSAGE
try
{
WebResponse Response = Request.GetResponse();
HttpStatusCode ResponseCode = ((HttpWebResponse)Response).StatusCode;
if (ResponseCode.Equals(HttpStatusCode.Unauthorized) || ResponseCode.Equals(HttpStatusCode.Forbidden))
{
var text = "Unauthorized - need new token";
}
else if (!ResponseCode.Equals(HttpStatusCode.OK))
{
var text = "Response from web service isn't OK";
}
StreamReader Reader = new StreamReader(Response.GetResponseStream());
string responseLine = Reader.ReadToEnd();
Reader.Close();
return responseLine;
}
catch (Exception e)
{
}
return "error";
}
public static bool ValidateServerCertificate(
object sender,
X509Certificate certificate,
X509Chain chain,
SslPolicyErrors sslPolicyErrors)
{
return true;
}
但是当我需要执行方法时（它要求我给它一个参数Browser-APIKey）
string deviceId = "APA91bHsQUsnYLHSFkmmJE8AgXEU--_nqPOJ5q2sfZIpCI1ZiJnmi2-IrZCqwummfJB94uVmqgT-ZWkyeIrICU8GpPvAOdmUfiVtYRmmA7bVAaKPuerJUcRUisveOe5Jp36-3fUK7VlDvwcme0SaJiwJU9B1y1EkF6YTQ00g";
string message = "some test message";
string tickerText = "example test GCM";
string contentTitle = "content title GCM";
string postData =
"{ \"registration_ids\": [ \"" + deviceId + "\" ], " +
"\"data\": {\"tickerText\":\"" + tickerText + "\", " +
"\"contentTitle\":\"" + contentTitle + "\", " +
"\"message\": \"" + message + "\"}}";
首先 --> 这种方法能帮助我正确发送推送通知吗？还是可以改进得更好？
如果好...
从哪里可以得到Browser KEY？？
提前致谢 ：）
