开始前的准备：

需要https://XXXXX下的访问证书保存为cer文件。

基础代码：

1、参考两篇文章：

http://blog.csdn.net/liuxiaoshuang002/article/details/51955020 用来判断是否为空

http://blog.csdn.net/liuxiaoshuang002/article/details/51955031 比较对象是否相等

2、请求后返回的实体 HttpResponseEntity 详细代码如下：

package com.gj5u.publics.util.httpweb;import java.util.Map;/** * 获取内容实体 * @author Rex * */public class HttpResponseEntity{    private Map<String,String> resHeaders;    private String httpBody;    private String statusLine;    private String ErrMessage;    /**     * Header信息     * @return Header信息     */    public Map<String, String> getResHeaders()    {        return resHeaders;    }    /**     * Header信息     * @param resHeaders Header信息     */    public void setResHeaders(Map<String, String> resHeaders)    {        this.resHeaders = resHeaders;    }    /**     *  Body 内容     * @return Body 内容     */    public String getHttpBody()    {        return httpBody;    }    /**     *  Body 内容     * @param httpBody Body 内容     */    public void setHttpBody(String httpBody)    {        this.httpBody = httpBody;    }    /**     * 状态行     * @return 状态行     */    public String getStatusLine()    {        return statusLine;    }    /**     * 状态行     * @param statusLine 状态行     */    public void setStatusLine(String statusLine)    {        this.statusLine = statusLine;    }    public String getErrMessage()    {        return ErrMessage;    }    public void setErrMessage(String errMessage)    {        ErrMessage = errMessage;    }    }

使用方法

  MyHttpsConn httpconn = new MyHttpsConn(httpsurl, CerPath);   //请求的URL和证书路径        HttpResponseEntity httpentry = httpconn.SendHttps(HttpMethod.GET, Parameters, ReqHeader, Body,GetHeader);
