Question

我创建了应用服务器，通过http post将消息发送到gcm服务器。执行代码后，我得到的响应代码为200，但显示的结果为Error=MissingRegistration。

我无法理解为什么缺少注册ID。我已成功通过在其上创建Google帐户来获取模拟器的注册ID。我已经验证了我的项目ID和密钥，并且还使用了gcm-server.jar来创建服务器。我也尝试使用服务器密钥而不是浏览器密钥，但仍然得到相同的结果。

以下是我的应用程序服务器的代码，它通过http post将消息发送到gcm服务器。

    package com.example.gcmserver;

    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.util.ArrayList;
    import java.util.List;

    import org.apache.http.HttpException;
    import org.apache.http.HttpRequest;
    import org.apache.http.HttpRequestInterceptor;
    import org.apache.http.HttpResponse;
    import org.apache.http.NameValuePair;
    import org.apache.http.auth.AuthScope;
    import org.apache.http.auth.AuthState;
    import org.apache.http.auth.Credentials;
    import org.apache.http.auth.UsernamePasswordCredentials;
    import org.apache.http.client.CredentialsProvider;
    import org.apache.http.client.entity.UrlEncodedFormEntity;
    import org.apache.http.client.methods.HttpPost;
    import org.apache.http.client.protocol.ClientContext;
    import org.apache.http.impl.auth.BasicScheme;
    import org.apache.http.impl.client.DefaultHttpClient;
    import org.apache.http.message.BasicNameValuePair;
    import org.apache.http.protocol.HttpContext;

    public class Server {
        public static void main(String[] args) throws IOException {

            DefaultHttpClient client = new DefaultHttpClient();
            client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("username", "password"));
            client.addRequestInterceptor(new HttpRequestInterceptor() {


        @Override
        public void process(HttpRequest arg0, HttpContext context)
                throws HttpException, IOException {
            // TODO Auto-generated method stub
              AuthState state = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE);
                 if (state.getAuthScheme() == null) {
                     BasicScheme scheme = new BasicScheme();
                     CredentialsProvider credentialsProvider = (CredentialsProvider) context.getAttribute(ClientContext.CREDS_PROVIDER);
                     Credentials credentials = credentialsProvider.getCredentials(AuthScope.ANY);
                     if (credentials == null) {
                         throw new HttpException();
                     }
                     state.setAuthScope(AuthScope.ANY);
                     state.setAuthScheme(scheme);
                     state.setCredentials(credentials);
        }}
     }, 0); 
                    HttpPost httppost = new HttpPost("https://android.googleapis.com/gcm/send");

              List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
              urlParameters.add(new BasicNameValuePair("data.registration id","APA91bERSCmbVV-diaS7OkA6nQlatuq1e8whUhjN54WcsfasiY3PSlby2_DtSq7Gjs_rXcOuUPTj8obnvnD55VbXJiWvWgXGj71oRFw_0yP4uz9JGDTax5dY-DKhnk6tK2gEFy50bDuKebQoRnUo9CYfSSW3AAtqV4tJDKv4GYwtUI0vIUliSJM"));

              urlParameters.add(new BasicNameValuePair("data.title", "e-pass application"));
              urlParameters.add(new BasicNameValuePair("data.message", "Your code is 13133"));


              httppost.setHeader("Authorization",
                      "key=mybrowserkey");
              httppost.setHeader("Content-Type",
                      "application/x-www-form-urlencoded;charset=UTF-8");
              httppost.setHeader("Sender_ID", "myprojectid");

              httppost.setEntity(new UrlEncodedFormEntity(urlParameters, "UTF-8"));

              HttpResponse response = client.execute(httppost);
              System.out.println("Response Code : " 
                          + response.getStatusLine().getStatusCode());
              System.out.println("Getting the contents of the message");

              BufferedReader rd = new BufferedReader(
                      new InputStreamReader(response.getEntity().getContent()));

              StringBuffer result = new StringBuffer();
              String line = "";
              while ((line = rd.readLine()) != null) {
                  result.append(line);
              }


              System.out.println("the result is:"+result);
    }
    }

我已经参考了这个链接来创建服务器： Trying to HTTP-POST to GCM from Java

非常感谢您的帮助。

无需使用＆＃34;数据前缀注册ID。＆＃34;。键值对应为：registration_ids，包含注册ID的数组
