当我在我的应用程序上执行同步时,遇到此错误时出现问题.主要问题是相同的代码适用于
Android 6.0.1设备,但在4.4.2设备上,我收到此错误：
javax.net.ssl.SSLException: Connection closed by peer at com.android.org.conscrypt.NativeCrypto.SSL_do_handshake(Native Method) at com.android.org.conscrypt.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:406) at okhttp3.internal.io.RealConnection.connectTls(RealConnection.java:188) at okhttp3.internal.io.RealConnection.connectSocket(RealConnection.java:145) at okhttp3.internal.io.RealConnection.connect(RealConnection.java:108) at okhttp3.internal.http.StreamAllocation.findConnection(StreamAllocation.java:188) at okhttp3.internal.http.StreamAllocation.findHealthyConnection(StreamAllocation.java:127) at okhttp3.internal.http.StreamAllocation.newStream(StreamAllocation.java:97) at okhttp3.internal.http.HttpEngine.connect(HttpEngine.java:289) at okhttp3.internal.http.HttpEngine.sendRequest(HttpEngine.java:241) at okhttp3.RealCall.getResponse(RealCall.java:240) at okhttp3.RealCall$ApplicationInterceptorChain.proceed(RealCall.java:198) at okhttp3.logging.HttpLoggingInterceptor.intercept(HttpLoggingInterceptor.java:203) at okhttp3.RealCall$ApplicationInterceptorChain.proceed(RealCall.java:187) at okhttp3.RealCall.getResponseWithInterceptorChain(RealCall.java:160) at okhttp3.RealCall.access$100(RealCall.java:30) at okhttp3.RealCall$AsyncCall.execute(RealCall.java:127) at okhttp3.internal.NamedRunnable.run(NamedRunnable.java:33) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1112) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587) at java.lang.Thread.run(Thread.java:841)
我无法从服务器请求数据.
如果您需要更多数据,请随时问.谢谢.
解决方法
这里的关键是强制TLS 1.2协议,基于
this链接.
只需要在这里纠正的事情就是直接强制使用TLS 1.2协议,就像这样：
private class NoSSLv3SSLSocket extends DelegateSSLSocket {
private NoSSLv3SSLSocket(SSLSocket delegate) {
super(delegate);
}
@Override
public void setEnabledProtocols(String[] protocols) {
super.setEnabledProtocols(new String[]{"TLSv1.2"}); // force to use only TLSv1.2 here
}
}
