httpclient 4.1.2 的SSL使用方法

一、定义类：

public class DefaultTrustManager implements X509TrustManager {
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}

}

二、调用代码

HttpClient client = new DefaultHttpClient();

SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(new KeyManager[0], 
new TrustManager[] {new DefaultTrustManager()},
new SecureRandom());

SSLSocketFactory sf = new SSLSocketFactory(
ctx,
SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

Scheme https = new Scheme("https", 8443, sf);

client.getConnectionManager().getSchemeRegistry().register(https);

// 往下即可使用https通信，调用方法和http没有区别。
