本篇文章主要介绍了JAVA利用HttpClient进行HTTPS接口调用的方法，具有一定的参考价值，有兴趣的可以了解一下

本文介绍了JAVA利用HttpClient进行HTTPS接口调用的方法，分享给大家，具体如下：

1.为了避免需要证书，所以用一个类继承DefaultHttpClient类，忽略校验过程。

									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;

									/**

									 * 用于进行Https请求的HttpClient 

									 * @ClassName: SSLClient 

									 * @Description: TODO

									 * @author Devin <xxx> 

									 * @date 2017年2月7日 下午1:42:07 

									 * 

									 */

									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));

									  }

									}

2.创建一个利用HttpClient发送post请求的工具类

									import org.apache.http.HttpEntity;

									import org.apache.http.HttpResponse;

									import org.apache.http.StatusLine;

									import org.apache.http.client.HttpClient;

									import org.apache.http.client.methods.HttpPost;

									import org.apache.http.entity.StringEntity;

									import org.apache.http.message.BasicHeader;

									import org.apache.http.util.EntityUtils;

									/**

									 * 利用HttpClient进行post请求的工具类

									 * @ClassName: HttpClientUtil 

									 * @Description: TODO

									 * @author Devin <xxx> 

									 * @date 2017年2月7日 下午1:43:38 

									 * 

									 */

									public class HttpClientUtil {

									  @SuppressWarnings("resource")

									  public static String doPost(String url,String jsonstr,String charset){

									    HttpClient httpClient = null;

									    HttpPost httpPost = null;

									    String result = null;

									    try{

									      httpClient = new SSLClient();

									      httpPost = new HttpPost(url);

									      httpPost.addHeader("Content-Type", "application/json");

									      StringEntity se = new StringEntity(jsonstr);

									      se.setContentType("text/json");

									      se.setContentEncoding(new BasicHeader("Content-Type", "application/json"));

									      httpPost.setEntity(se);

									      HttpResponse response = httpClient.execute(httpPost);

									      if(response != null){

									        HttpEntity resEntity = response.getEntity();

									        if(resEntity != null){

									          result = EntityUtils.toString(resEntity,charset);

									        }

									      }

									    }catch(Exception ex){

									      ex.printStackTrace();

									    }

									    return result;

									  }

									}

3.测试代码

									public static void main(String[] args){ 

									    String url = "https://192.168.1.101/xxx";

									    String jsonStr = "{xxx}";

									    String httpOrgCreateTestRtn = HttpClientUtil.doPost(url, jsonStr, "utf-8");

									  }
