【问题描述】：

我已通过 GCM 使用 ASP.net C# 向安卓手机发送推送通知。

但我尝试了不同类型的代码，但所有 arr 都返回 Missing Registration 错误，所以请帮助我。

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：

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;
    

【问题讨论】：

哼哼开始你的android代码很脏，请缩进和所有x）

@Yume117: 它的 c# 代码

使用github.com/Redth/PushSharp

'®istration_id' - 这是您的帖子或实际代码中的错字吗？

【参考方案1】：

当您未能在请求中包含注册 ID 时，GCM 会返回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 &registration_id=your_registration_id 而不是 ®istration_id= 作为您发布的代码中的传递。
