转载-解决使用httpClient 4.3.x登陆 https时的证书报错问题

今天在使用httpClient4.3.6模拟登陆https网站的时候出现了证书报错的问题，这是在开源中国社区里找到的可行的答案(原文链接:http://www.oschina.net/question/194048_135225?sort=time)

大概逻辑是自己实现了信任所有证书

import javax.net.ssl.SSLContext;
 
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.SSLContextBuilder;
import org.apache.http.conn.ssl.TrustStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
/**

public abstract class SSLUtils {
 
    public static CloseableHttpClient createSSLInsecureClient() {
        try {
            SSLContext sslContext = new SSLContextBuilder()
                                .loadTrustMaterial(null, new TrustStrategy() {
                //信任所有
                public boolean isTrusted(X509Certificate[] chain,
                                String authType) throws CertificateException {
                    return true;
                }
                    }).build();
            SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                    sslContext);
            return HttpClients.custom().setSSLSocketFactory(sslsf).build();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyStoreException e) {
            e.printStackTrace();
        }
        return  HttpClients.createDefault();
    }
 
}
