支持https 但不验证证书的 Httpclient 工具类

情况是这样的，公司是做支付业务的，所以有异步通知订单的业务，商户有https，http 都有的

但是有一些商户的https 一个证书对应多个域名的情况，亦或者自建证书，所有我们需要修改成视情况而定的放弃证书的校验

下面直接提出工具类 

SSLClient 跳过证书校验返回 CloseableHttpClient 

package http;
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  
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);  
        //允许所有证书
        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));  
    }  
}  

HTTP请求工具类，这个工具类基本的请求都包含了，也可以自行添加修改发送方式，如body方式等

目前是json 和map 的两种方式 有校验证书的，有不校验证书的，根据方法名就可以看出

下拉
