【问题描述】:
我正在尝试通过推送通知来通知设备
我收到了来自GCM 服务器的回复
{"multicast_id":8594338261894783737,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1355822022916886%8ae6056ef9fd7ecd"}]}
但仍然没有收到通知
知识 --> "success":1
但我认为这里有问题 --> "canonical_ids":0
这是我的代码...
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(HttpRequestHeader.Authorization, string.Format("key={0}",apiKey));
Request.ContentLength = byteArray.Length;
Stream dataStream = Request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
try
{
WebResponse Response = Request.GetResponse();
HttpStatusCode ResponseCode = ((HttpWebResponse)Response).StatusCode;
if (ResponseCode.Equals(HttpStatusCode.Unauthorized) || ResponseCode.Equals(HttpStatusCode.Forbidden))
{
Label1.Text = "Unauthorized - need new token";
}
else if (!ResponseCode.Equals(HttpStatusCode.OK))
{
Label1.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";
}
// return "error";
}
我调用这个方法使用
string deviceId = "APA91bHomX3zb6Y87fb4GAjyj8zIaI-tt1n6ZFmgtmu16nmLW7ntwnOyv4BXMH7RzQWk3JrKdLjttJMxKzvpFd3Kmrid_RzsC3zR46GLJGiZKERXOSIR8fYReBEfz1f0G_FIm5bPttWUBDwz9jPuF2lS8RQh-0DKbw";
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 + "\"}}";
Label1.Text = SendGCMNotification("AIzaSyBEvtrtbbfy2-p2zS8Zi8DweZiRy8M-nZc", postData);
提前致谢
