我尝试从http://developer.android.com/guide/google/gcm/gs.html实现 GCM

我无法向应用程序发送消息。我将 System.setProperty... 添加到 servlet 和 http.proxyHost=proxy.company.com http.proxyPort=8080 到 catalina.properties 从此页面Google 云消息传递 GCM 通过代理

Servlet: Sender sender = new Sender(myApiKey);

                Message message = new Message.Builder()
                .collapseKey("1")
                .timeToLive(3)
                .delayWhileIdle(true)
                .addData("message", "message is created at builder")
                .build();

                System.setProperty("http.proxyHost", "10.200.125.200");  
                System.setProperty("http.proxyPort", "8080"); 

                Result result = sender.send(message, reGid, 5);
                System.out.println("result of message is "+ result);

GCMIntentService.java：

@Override
protected void onMessage(Context arg0, Intent arg1) {
Log.i(TAG, "new message= ");
Toast.makeText(this, arg1.getStringExtra("message"), Toast.LENGTH_SHORT).show();
}

sender.send 不起作用，我认为代理会阻止它。安慰：

我如何设置 sender.send 或通过代理？

GCM 端点服务器使用 HTTPS。您可以尝试以下系统属性：

System.setProperty("https.proxyHost", "10.200.125.200");  
System.setProperty("https.proxyPort", "8080");

我遇到了同样的问题，这里提到的 System.setProperty 没有帮助。

我在下面创建了类并重构了代码以使用 ProxySender 而不是 Sender 类，它最终可以工作。

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.URL;

import com.google.android.gcm.server.Sender;

public class ProxySender extends Sender {

    public ProxySender(String key) {
        super(key);
        // TODO Auto-generated constructor stub
    }

    @Override
    protected HttpURLConnection getConnection(String url) throws IOException {

        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("1.2.3.4.", 8080));

        HttpURLConnection conn = (HttpURLConnection) new URL(url).openConnection(proxy);

        return conn;

    }
}

记得修改代理服务器和端口。
