httpClient 4.2版本發送https請求忽略證書
1 創建忽略證書的httpsClient類繼承默認的DefaultHttpClient

package cn.com.maxtech.website.call;

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;

public class HttpsClient extends DefaultHttpClient {

    public HttpsClient() 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));
    }
}

2 創建發送json數據的方法

public static Map<String, String> postJosnHttps(String url, Map<String, String> params, Map<String, String> heads,
            String charset) throws Exception {
        DefaultHttpClient httpClient = null;
        HttpPost httpPost = null;
        String result = null;
        Map<String, String> resMap = new HashMap<String, String>();
        try {
            httpClient = new HttpsClient();
            httpPost = new HttpPost(url);
            // 設置參數
            List<NameValuePair> list = new ArrayList<NameValuePair>();
            Iterator iterator = params.entrySet().iterator();
            while (iterator.hasNext()) {
                Entry<String, String> elem = (Entry<String, String>) iterator.next();
                list.add(new BasicNameValuePair(elem.getKey(), elem.getValue()));
            }
            Header[] heads1 = new Header[heads.size()];
            int i = 0;
            for (Entry<String, String> head : heads.entrySet()) {
                heads1[i] = new BasicHeader(head.getKey(), head.getValue());
                i++;
            }
            if (heads1.length > 0) {
                httpPost.setHeaders(heads1);
            }
            if (list.size() > 0) {
                String reqstr = JsonUtils.mapToStr((Map) params);
                StringEntity entity = new StringEntity(reqstr);
                log.debug(" 請求 = " + reqstr);
                httpPost.setEntity(entity);
            }

            HttpResponse response = httpClient.execute(httpPost);
            if (response != null) {
                HttpEntity resEntity = response.getEntity();
                result = EntityUtils.toString(resEntity, charset);
                resMap = JsonUtils.strToMap(result);
            }
            return resMap;
        } catch (Exception ex) {
            log.error(ex);
            ex.printStackTrace();
            return resMap;
        }
    }

    public static Map<String, String> postParamHttps(String url, Map<String, String> params, Map<String, String> heads,

                list.add(new BasicNameValuePair(elem.getKey(), elem.getValue()));
            }
            Header[] heads1 = new Header[heads.size()];
            int i = 0;
            for (Entry<String, String> head : heads.entrySet()) {
