Android的GCM丢失的注册C＃ [英] Android GCM Missing Registration C#

问题描述

我想实现使用谷歌GCM推送通知，但是，当我尝试将通知发送到GCM，我发现了 MissingRegistration 错误。

I'm trying to implement a push notification using the Google GCM, but, when I try to send a notification to GCM I'm getting the MissingRegistration error.

我使用的是伪造的注册ID到目前为止，但我认为这有点像'注册没有找到在这种情况下提出的，对吧？

I'm using fake registration ids so far but I think that something like 'Registration not found' is raised in this case, right?

下面我的C＃件code的

Here my C# piece of code

    public static void send(List<String> clientRegistrationIds, GcmData data)
    {
        WebRequest request = WebRequest.Create(SEND_URL);

        // Headers.
        request.Method = POST;
        request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
        request.Headers.Add(string.Format("Authorization: key={0}", API_KEY));
        request.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));

        string postData = new JavaScriptSerializer().Serialize(new GcmRequest(clientRegistrationIds, data));
        Console.WriteLine(postData);

        Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
        request.ContentLength = byteArray.Length;

        Stream dataStream = request.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        dataStream.Close();

        WebResponse tResponse = request.GetResponse();

        dataStream = tResponse.GetResponseStream();

        StreamReader tReader = new StreamReader(dataStream);

        String sResponseFromServer = tReader.ReadToEnd();
        Console.WriteLine(sResponseFromServer);

        tReader.Close();
        dataStream.Close();
        tResponse.Close();
    }

序列化POSTDATA变量：

The serialized postData variable:

{"registration_ids":["123"],"data":{"message":"New request!"}}

我的回答是：

Error=MissingRegistration

我在做什么错了？

What I'm doing wrong?

谢谢！

编辑：更改内容类型为应用程序/ JSON 工作。现在，我得到了我期待的错误： InvalidRegistration 。但应用程序/ x-WWW的形式urlen codeD;字符集= UTF-8 不应该是正确的内容类型

Changing the content-type to application/json worked. Now i'm getting the error that I was expecting: InvalidRegistration. BUT, application/x-www-form-urlencoded;charset=UTF-8 wasn't supposed to be the correct Content-Type?

推荐答案

改变了的ContentType为应用程序/ JSON 和它的工作。

Changed the ContentType to application/json and it worked.
