目前，要為另一個專案提供介面，介面是用HTTP URL實現的，最初的想法是另一個專案用JQuery post進行請求。

但是，很可能另一個專案是部署在別的機器上，那麼就存在跨域問題，而JQuery的post請求是不允許跨域的。

這時，就只能夠用HttpClient包進行請求了，同時由於請求的URL是HTTPS的，為了避免需要證書，所以用一個類繼承DefaultHttpClient類，忽略校驗過程。

1.寫一個SSLClient類，繼承至HttpClient

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.http.conn.ClientConnectionManager;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;
//用於進行Https請求的HttpClient
public class SSLClient extends DefaultHttpClient{
	public SSLClient() throws Exception{
        super();
        SSLContext ctx = SSLContext.getInstance("TLS");
        X509TrustManager tm = new X509TrustManager() {
                @Override
                public void checkClientTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                }
                @Override
                public void checkServerTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                }
                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                }
        };
        ctx.init(null, new TrustManager[]{tm}, null);
        SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
        ClientConnectionManager ccm = this.getConnectionManager();
        SchemeRegistry sr = ccm.getSchemeRegistry();
        sr.register(new Scheme("https", 443, ssf));
    }
}
