这是我为GCM创建的示例服务器。
class Program2
{
public static string SenderId = "318115091714";
public static string RegistrationID = "APA91bF9hn6VeessobraNuauBcrFdlJ9eH1eVb44FAQ2oawerBeFWS48IEIFTPo8fdvWm93hwFY0tKszpPuSObPbTqgW-za1RLhCw-GDCn4JQZLQ-CmGwnnr6F5X8gYhNa2DNvFhCEM7HNgvdxtcnBqVX0dVnEynXQ";
public static string ApiKey = "AIzaSyAl2HdB4bbukkcmJwoxUmhof15IAiuJ16U";
public static string Message = "Testing GCM Server";
public static string ApplicationId = "com.google.android.gcm.demo.app";
/// <summary>
/// Main method
/// </summary>
public static void Main(string[] args)
{
try
{
Program2 objProgram2 = new Program2();
Console.WriteLine("\nPlease wait while GCM server is processing...");
string Text = objProgram2.SendMessage();
Console.WriteLine("\nSendMessage Response: " + Text);
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine("\n" + ex.Message);
Console.WriteLine("\n" + ex.StackTrace);
Console.ReadLine();
}
}
/// <summary>
/// Send Push Message to Device
/// </summary>
public string SendMessage()
{
//-- Create Query String --//
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.Message=" + Message + "&data.time=" + System.DateTime.Now.ToString() + "®istration_id=" + RegistrationID + "";
//Console.WriteLine(postData);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
//-- Create GCM Request Object --//
HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://android.googleapis.com/gcm/send");
Request.Method = "POST";
Request.KeepAlive = false;
Request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
Request.Headers.Add(string.Format("Authorization: key={0}", ApiKey));
Request.Headers.Add(string.Format("Sender: id={0}", SenderId));
Request.ContentLength = byteArray.Length;
//-- Delegate Modeling to Validate Server Certificate --//
ServicePointManager.ServerCertificateValidationCallback += delegate(
object
sender,
System.Security.Cryptography.X509Certificates.X509Certificate
pCertificate,
System.Security.Cryptography.X509Certificates.X509Chain pChain,
System.Net.Security.SslPolicyErrors pSSLPolicyErrors)
{
return true;
};
//-- Create Stream to Write Byte Array --//
Stream dataStream = Request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
//-- Post a Message --//
WebResponse Response = Request.GetResponse();
HttpStatusCode ResponseCode = ((HttpWebResponse)Response).StatusCode;
if (ResponseCode.Equals(HttpStatusCode.Unauthorized) || ResponseCode.Equals(HttpStatusCode.Forbidden))
{
return "Unauthorized - need new token";
}
else if (!ResponseCode.Equals(HttpStatusCode.OK))
{
return "Response from web service isn't OK";
//Console.WriteLine("Response from web service is not OK :");
//Console.WriteLine(((HttpWebResponse)Response).StatusDescription);
}
StreamReader Reader = new StreamReader(Response.GetResponseStream());
string responseLine = Reader.ReadLine();
Reader.Close();
return responseLine;
}
}
使用这些有效值和键运行后,我收到了此响应。
Please wait while GCM server is processing...
SendMessage Response: Error=NotRegistered
我得到了Error=NotRegistered
。 Android开发人员指南中甚至没有指定此响应。我得到这个回应的原因是什么?任何人都可以帮我解决这个问题吗?提前谢谢。
答案 0 :(得分:7)
我已经找到了它发生的原因。可能有六种类型的回复。以下是回复列表及其含义。
{ "message_id": "1:0408" } - success
{ "error": "Unavailable" } - should be resent
{ "error": "InvalidRegistration" } - had an unrecoverable error (maybe the value got corrupted in the database)
{ "message_id": "1:1516" } - success
{ "message_id": "1:2342", "registration_id": "32" } - success, but the registration ID should be updated in the server database
{ "error": "NotRegistered"} - registration ID should be removed from the server database because the application was uninstalled from the device
我收到错误消息6.使用新的发件人ID,注册ID和API密钥,上面的代码正常运行。
答案 1 :(得分:3)
我不是服务器人,但最近查看了GCM服务器代码以解决问题。所以我在这里找到了:
您设置API密钥的代码行:
Request.Headers.Add(string.Format("Authorization: key={0}", ApiKey));
看起来不对我。 key = 字应该连接到api键,然后你的行看起来像这样:
Request.Headers.Add("Authorization", "key=" + ApiKey));
这就是我最终的成就。
对于发件人ID,我们有不同的方法,因此请检查这行代码:
Request.Headers.Add(string.Format("Sender: id={0}", SenderId));
