我正在使用以下客户端SSLSocketFactory代码发送文本，然后最终将.wav文件发送到正在侦听的服务器，但是此代码给了我两个错误。
这两行给我错误:
SSLSocketFactory socketFactory = new SSLSocketFactory(ks);
这就是说
SSLSocketFactory是抽象的，无法实例化。socketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
为此，该错误是无法解析方法
setHostnameVerifier且无法解析符号ALLOW_ALL_HOSTNAME_VERIFIER。整个代码:
Button send;
EditText textSend;
private String ip_address = "192.168.10.103";
private int port = 5000;
private SSLSocket socket = null;
private BufferedWriter out = null;
private BufferedReader in = null;

上面的两个问题我已经解决，但我有此错误输出:
FATAL EXCEPTION: main
Process: com.example.admirmonteiro.testclient, PID: 13735
android.os.NetworkOnMainThreadException
`at` `android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1273)`
最佳答案
SSLSocketFactory是抽象的，因此您必须使用其子级之一。您可以使用SSLSocketFactory.getDefault()来获取默认实现。setHostnameVerifier()是HttpsURLConnection而非SSLSocketFactory的方法。您应该在代码的该部分中使用它。
如果您不使用HttpsURLConnection，则可以并且应该这样验证网址:
// Open SSLSocket directly to gmail.com
SocketFactory sf = SSLSocketFactory.getDefault();
SSLSocket socket = (SSLSocket) sf.createSocket("gmail.com", 443);
HostnameVerifier hv = HttpsURLConnection.getDefaultHostnameVerifier();
SSLSession s = socket.getSession();
// Verify that the certicate hostname is for mail.google.com
// This is due to lack of SNI support in the current SSLSocket.
if (!hv.verify("mail.google.com", s)) {
throw new SSLHandshakeException("Expected mail.google.com, "
"found " + s.getPeerPrincipal());
}
// At this point SSLSocket performed certificate verificaiton and
// we have performed hostname verification, so it is safe to proceed.
// ... use socket ...
socket.close();
