我已使用 GCM 的 ASP.net C# 向 Android 手机发送推送通知。
但是我尝试了不同类型的代码,但都返回缺少注册错误,所以请帮助我。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using PushNotification;
namespace TestAndroidPush
{
public partial class Test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Main();
}
}
private void Main()
{
AndroidGCMPushNotification apnGCM = new AndroidGCMPushNotification();
string strResponse = apnGCM.SendNotification(device id, "Test Push");
}
}
}
cs 文件:
using System;

using System.Web;
using System.Net;
using System.Text;
using System.IO;
using System.Security.Cryptography.X509Certificates;
using System.Net.Security;
using System.Collections.Specialized;
public class AndroidGCMPushNotification
{
public AndroidGCMPushNotification()
{
//
// TODO: Add constructor logic here
//
}
public string SendNotification(string deviceId, string message)
{
string GoogleAppID = "GoogleAppID";
var SENDER_ID = "sender id";
var value = message;
WebRequest tRequest;
tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
tRequest.Method = "post";
tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));
tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
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 + "";
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();
return sResponseFromServer;
}
}
最佳答案
当您未能在请求中包含注册 ID 时,GCM 将返回
MissingRegistration
。
对于您使用的纯文本请求(基于您的 application/x-www-form-urlencoded;charset=UTF-8
内容类型),注册 ID 应作为 ®istration_id=your_registration_id
而不是您发布的代码中的 ®istration_id=
。
