android 使用https时 证书如果是用来测试的会爆出下面问题：
javax.net.ssl.SSLHandshakeException:
java.security.cert.CertPathValidatorException:
Trust anchor for certification path not found解决办法是将证书验证屏蔽掉：
HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST"); urlConnection.setSSLSocketFactory(context.getSocketFactory());
urlConnection.setHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
