我在尝试:
private void GcmPushNotification(string deviceId)
{
string message="New post from Admin";
string GoogleAppID = "AIzaSyCYesJ5dCK8-O-tf8ZxADELQx5e05P-l5I";
var SENDER_ID = "854837747831";
var value = message;
WebRequest tRequest;
tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
tRequest.Method = "post";
// --- text
tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message="
+ value + "&data.time=" + System.DateTime.Now.ToString() + "®istration_id=" + deviceId + "";
tRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));
Console.WriteLine(postData);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
tRequest.ContentLength = byteArray.Length;
Stream dataStream = tRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse tResponse = tRequest.GetResponse();
dataStream = tResponse.GetResponseStream();
StreamReader tReader = new StreamReader(dataStream);
String sResponseFromServer = tReader.ReadToEnd();
tReader.Close();
dataStream.Close();
tResponse.Close();
}
答案 0 :(得分:0)
如果要向多个设备发送相同的通知(最多1000个注册ID),则必须使用JSON请求格式,而不是您当前使用的编码的URL。
例如(取自here):
Content-Type:application/json Authorization:key=AIzaSyB-1uEai2WiUapxCs2Q0GZYzPu7Udno5aA { "registration_ids" : ["APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx..."], "data" : { ... }, }
