java 远程调用 httpclient 调用https接口 忽略SSL认证
httpclient 调用https接口，为了避免需要证书，所以用一个类继承DefaultHttpClient类，忽略校验过程。下面是忽略校验过程的代码类：SSLClient
package com.pms.common.https;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**/
public class SSLClient extends DefaultHttpClient {public SSLClient() throws Exception{super();SSLContext ctx = SSLContext.getInstance("TLS");ctx.init(null, getTrustingManager(), 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));}private static TrustManager[] getTrustingManager() {TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {@Overridepublic void checkClientTrusted(java.security.cert.X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic void checkServerTrusted(java.security.cert.X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic java.security.cert.X509Certificate[] getAcceptedIssuers() {return null;}} };return trustAllCerts;}
}
然后再调用的远程get、post请求中使用SSLClient 创建Httpclient ，代码如下：
package com.pms.common.https;import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.StatusLine;

import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicHeader;
