Question

我们已成功从带有HTTP网址的网络服务器获取数据近2年而没有任何打嗝。

最近我们出于某些安全原因迁移到了HTTPS。这就是问题发生的时候。

使用WiFi一切正常，当我定期连接到2G口袋数据时，我正在通过服务器问题重置连接。

我正在使用DefaultHttpClient连接到服务器。

我尝试了很多工作，但没有任何事情能够救出我。

javax.net.ssl.SSLException: Read error: ssl=0x56e63588: I/O error during system call, Connection reset by peer

我已将所有可用属性应用于HttpConnectionParams

HttpConnectionParams.setConnectionTimeout(httpClient.getParams(),120000);
HttpConnectionParams.setSoTimeout(httpClient.getParams(), 120000);
HttpConnectionParams.setLinger(httpClient.getParams(), 120000);
HttpConnectionParams.setTcpNoDelay(httpClient.getParams(), true);
HttpConnectionParams.setStaleCheckingEnabled(httpClient.getParams(), false);

另一个谷歌小组的讨论表明，这个问题可能是一个理想的活动状态的原因。所以我实施了这样的事情来保持屏幕清醒。

powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK,"My Tag");
wakeLock.acquire();

在onDestroy()我用wakeLock.release();

但这也无济于事。

在服务器端还有什么我需要检查的吗？

我遇到了类似的SSL错误。事实证明，棒棒糖前设备不支持SSL TLSv1.1，TLSv1.2。我通过包含一个启用这些SSL协议的TLSSocketFactory包装类来修复它。尝试在代码中添加以下内容：

    static {
    final SSLSocketFactory sslSocketFactory;
    try {
        sslSocketFactory = new TLSSocketFactory();
        HttpsURLConnection.setDefaultSSLSocketFactory(sslSocketFactory);
    } catch (KeyManagementException ignored) {

    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
}

import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;

import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;

public class TLSSocketFactory extends SSLSocketFactory {

    private SSLSocketFactory internalSSLSocketFactory;

    public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, null, null);
        internalSSLSocketFactory = context.getSocketFactory();
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return internalSSLSocketFactory.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return internalSSLSocketFactory.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
    }

    @Override
    public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
    }

    @Override
    public Socket createSocket(InetAddress host, int port) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
    }

    private Socket enableTLSOnSocket(Socket socket) {
        if(socket != null && (socket instanceof SSLSocket)) {
            ((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
        }
        return socket;
    }
}
