我打电话给托管Web服务器上的SSL证书无效的HTTP服务。 在开发中，我输入了keytool的证书，但该证书将是每个客户端上安装不同的，所以我不能只将其捆绑。
前言：我知道 ，跳绳SSL验证实在是太丑了。 在这种特殊情况下，我甚至不会需要SSL和系统中的所有其他通信都是通过简单的HTTP。 所以，我真的不关心MITM攻击或此类。 攻击者不需要去尽可能打破SSL，因为没有为数据没有SSL。 这是一个遗留系统在这我管不着支持。
我使用HttpURLConnection有SSLSocketFactory具有NaiveTrustManager和NaiveHostnameVerifier 。 此工程部分自签名的服务器我试过，但没有在客户的网站上。 我得到的错误是：
javax.net.ssl.SSLKeyException: [Security:090477]Certificate chain received from xxxxxxxxxx was not trusted causing SSL handshake failure.

我SimpleSocketFactory的样子：
public static final SSLSocketFactory getSocketFactory()
{
if ( sslSocketFactory == null ) {
try {
// get ssl context
SSLContext sc = SSLContext.getInstance("SSL");
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[]{
new NaiveTrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
log.debug("getAcceptedIssuers");
return new java.security.cert.X509Certificate[0];
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
log.debug("checkClientTrusted");
}
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
log.debug("checkServerTrusted");
}
}
};
sc.init(null, trustAllCerts, new java.security.SecureRandom());
// EDIT: fixed the following line that was redeclaring SSLSocketFactory sslSocketFactory, returning null every time. Same result though.
sslSocketFactory = sc.getSocketFactory();
HttpsURLConnection.setDefaultSSLSocketFactory(sslSocketFactory);
// EDIT: The following line has no effect
//HttpsURLConnection.setDefaultHostnameVerifier(new NaiveHostNameVerifier());
} catch (KeyManagementException e) {
log.error ("No SSL algorithm support: " + e.getMessage(), e);
} catch (NoSuchAlgorithmException e) {
log.error ("Exception when setting up the Naive key management.", e);
}
}
return sslSocketFactory;
}
该NaiveHostnameVerifier有办法限制的有效主机，但它保留为空，所以基本上任何接受：
public class NaiveHostnameVerifier implements HostnameVerifier {
String[] patterns;
public NaiveHostnameVerifier () {
this.patterns=null;
}
public NaiveHostnameVerifier (String[] patterns) {
this.patterns = patterns;
}
public boolean verify(String urlHostName,SSLSession session) {
if (patterns==null || patterns.length==0) {
return true;
} else {
for (String pattern : patterns) {
if (urlHostName.matches(pattern)) {
return true;
}
}
return false;
}
}
}
用法是这样的：
try {
conn = (HttpURLConnection)url.openConnection();
if (conn instanceof HttpsURLConnection) {
((HttpsURLConnection)conn).setSSLSocketFactory(SimpleSSLSocketFactory.getSocketFactory());
// EDIT: added this line, the HV has to be set on connection, not on the factory.
((HttpsURLConnection)conn).setHostnameVerifier(new NaiveHostnameVerifier());
}
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-type","application/x-www-form-urlencoded");
conn.connect();
StringBuffer sbContent = new StringBuffer();
// (snip)
DataOutputStream stream = new DataOutputStream(conn.getOutputStream ());
stream.writeBytes(sbContent.toString());
stream.flush();
stream.close();
} catch (ClassCastException e) {
log.error("The URL does not seem to point to a HTTP connection");
return null;
} catch (IOException e) {
log.error("Error accessing the requested URL", e);
return null;
}
当我在搜索上的错误消息，大多数人只是导入证书，在他们的商店，但再次，我真的不能这样做，因为我不知道哪个证书做到这一点会。 我如果这行不通唯一的选择就是让一个工具，可以下载证书，并在一个更简单的方式，神秘的命令行，但我宁愿让我的Java代码只是忽略无效的证书添加。
任何的想法 ？
