Question

我在这里使用我的浏览器密钥向gcm服务器发送消息。也尝试使用服务器密钥，但仍然得到相同的错误。我还尝试使用defaulthttpclient使用用户名和密码进行身份验证，但没有得到任何结果。

这是我的应用服务器的代码：

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 {

        String url = "https://android.googleapis.com/gcm/send";

        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 post = new HttpPost(url);


          HttpPost httppost = new HttpPost("https://android.googleapis.com/gcm/send");

          List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
          urlParameters.add(new BasicNameValuePair("data.registration id","APA91bGChJVdx2L1AUIJEVIBBVEkxEAk6zixj5V-L--fDGXudvrtl5gSQDgAP4iUJoMRq57sLSpGtsSQ5gnprX4McOPq7WxglKeQyTmaysVb0r-adOZ4tTjWG2MYwVEayFKy9Rwf1mloVt2jb-_izUdN-SfKvlpUpEYXNNT1987tYASKCcam16g"));

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


          httppost.setHeader("Authorization",
                  "key=AIzaSyDANlJHGPmzo1so_yyqkYZO7LSrQpnR7mk");
          httppost.setHeader("Content-Type",
                  "application/x-www-form-urlencoded;charset=UTF-8");

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

          HttpResponse response = client.execute(post);
          System.out.println("Response Code : " 
                      + response.getStatusLine().getStatusCode());

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

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

I have also add the httpclient, httpcore jar files in build path but still getting error.

有几种可能的原因导致响应代码401，例如项目ID中的错误。你可能已经忘记了在api控制台中启用云消息服务。
