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"); }
