今天刚学了网络编程在网上尝试下载东西时报:
sun.security.validator.ValidatorException: PKIX path building failed 异常
一阵搜错终于解决了,在这里记录下代码:具体请到上面的原作者阅读!
static HostnameVerifier hv = new HostnameVerifier() {
public boolean verify(String urlHostName, SSLSession session) {
System.out.println("Warning: URL Host: " + urlHostName + " vs. "
+ session.getPeerHost());
return true;
}
};
private static void trustAllHttpsCertificates() throws Exception {
javax.net.ssl.TrustManager[] trustAllCerts = new javax.net.ssl.TrustManager[1];
javax.net.ssl.TrustManager tm = new miTM();
trustAllCerts[0] = tm;
javax.net.ssl.SSLContext sc = javax.net.ssl.SSLContext
.getInstance("SSL");
sc.init(null, trustAllCerts, null);
javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(sc
.getSocketFactory());
}
static class miTM implements javax.net.ssl.TrustManager,
javax.net.ssl.X509TrustManager {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public boolean isServerTrusted(
java.security.cert.X509Certificate[] certs) {
return true;
}
public boolean isClientTrusted(
java.security.cert.X509Certificate[] certs) {
return true;
}
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType)
throws java.security.cert.CertificateException {
return;
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType)
throws java.security.cert.CertificateException {
return;
}
}
2)在访问https资源前,调用
trustAllHttpsCertificates();
HttpsURLConnection.setDefaultHostnameVerifier(hv);
