在使用new DefaultHttpClient(ClientConnectionManager clientConnectionManager)之前對clientConnectionManager進行初始化改造。

示例程式碼如下（重新定義一個DefaultHttpClient的子類。使用時new一個新的例項然後執行init方法，也可將初始化方法放在每個具體執行方法中）：

public class HttpsUtil extends DefaultHttpClient {

    public final static String HTTPGET = "GET";
    public
 
 final static String HTTPPUT = "PUT";
    public final static String HTTPPOST = "POST";
    public final static String HTTPDELETE = "DELETE";
    public final static String HTTPACCEPT = "Accept";
    public final static String CONTENT_LENGTH = "Content-Length";
    public final static String CHARSET_UTF8 = "UTF-8"
 
;
    private static HttpClient httpClient;

    public void init() throws Exception {
        String base_Path = "/Users/jinx/Documents/jobs/git_mine/base/base";// 存放證書資料夾位置 
        String selfcertpath = base_Path + "ca.jks";//自身cert
        String trustcapath = base_Path + "outgoing.CertwithKey.pkcs12"; //授信cert
 


        KeyStore selfCert = KeyStore.getInstance("pkcs12");
        selfCert.load(new FileInputStream(selfcertpath), Constant.SELFCERTPWD.toCharArray());
        KeyManagerFactory kmf = KeyManagerFactory.getInstance("sunx509");
        kmf.init(selfCert, Constant.SELFCERTPWD.toCharArray());
        KeyStore caCert = KeyStore.getInstance("jks");
        caCert.load(new FileInputStream(trustcapath), Constant.TRUSTCAPWD.toCharArray());
        TrustManagerFactory tmf = TrustManagerFactory.getInstance("sunx509");
        tmf.init(caCert);
        SSLContext sc = SSLContext.getInstance("TLSv1.2");//重點是這裡，JDK1.8使用TLS即可
        sc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
        SSLSocketFactory ssf = new SSLSocketFactory(sc, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
        ClientConnectionManager ccm = this.getConnectionManager();
        SchemeRegistry sr = ccm.getSchemeRegistry();
        sr.register(new Scheme("https", "埠", ssf));

        httpClient = new DefaultHttpClient(ccm);

    }

}
