让httpclient接受所有ssl证书https

访问https 资源时,让httpclient接受所有ssl证书,在weblogic等容器中很有用
代码如下:
import java.io.IOException;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.SocketFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.commons.httpclient.ConnectTimeoutException;
import org.apache.commons.httpclient.params.HttpConnectionParams;
import org.apache.commons.httpclient.protocol.SecureProtocolSocketFactory;
public class MySecureProtocolSocketFactory implements SecureProtocolSocketFactory {
static{
System.out.println(">>>>in MySecureProtocolSocketFactory>>");
}
private SSLContext sslcontext = null;
private SSLContext createSSLContext() {
SSLContext sslcontext=null;
try {
sslcontext = SSLContext.getInstance("SSL");
sslcontext.init(null, new TrustManager[]{new TrustAnyTrustManager()}, new java.security.SecureRandom());
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyManagementException e) {
e.printStackTrace();
}
return sslcontext;
}
private SSLContext getSSLContext() {
if (this.sslcontext == null) {
this.sslcontext = createSSLContext();
}
return this.sslcontext;
}
public Socket createSocket(Socket socket, String host, int port, boolean autoClose)
throws IOException, UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(
socket,
host,
port,
autoClose
);
}
public Socket createSocket(String host, int port) throws IOException,
UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(
host,
port
);
}
public Socket createSocket(String host, int port, InetAddress clientHost, int clientPort)
throws IOException, UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(host, port, clientHost, clientPort);
}
public Socket createSocket(String host, int port, InetAddress localAddress,
int localPort, HttpConnectionParams params) throws IOException,
UnknownHostException, ConnectTimeoutException {
if (params == null) {
throw new IllegalArgumentException("Parameters may not be null");
}
int timeout = params.getConnectionTimeout();
SocketFactory socketfactory = getSSLContext().getSocketFactory();
if (timeout == 0) {
return socketfactory.createSocket(host, port, localAddress, localPort);
} else {
Socket socket = socketfactory.createSocket();
SocketAddress localaddr = new InetSocketAddress(localAddress, localPort);
SocketAddress remoteaddr = new InetSocketAddress(host, port);
socket.bind(localaddr);
socket.connect(remoteaddr, timeout);
return socket;
}
}
//自定义私有类
private static class TrustAnyTrustManager implements X509TrustManager {
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[]{};
}
}
}
然后按如下方式使用HttpClient
Protocol myhttps = new Protocol("https", new MySecureProtocolSocketFactory (), 443);
Protocol.registerProtocol("https", myhttps);
HttpClient httpclient=new HttpClient();
