* @see 4)请求参数含中文等特殊字符时,可直接传入本方法,并指明其编码字符集encodeCharset参数,方法内部会自 动对其转码
* @see 5)该方法在解码响应报文时所采用的编码,取自响应消息头中的[Content-Type:text/html; charset=GBK]的 charset值
* @see 6)若响应消息头中未指定Content-Type属性,则会使用HttpClient内部默认的ISO-8859-1
* @param reqURL 请求地址
* @param param 请求参数,若有多个参数则应拼接为param11=value11&22=value22&33=value33的形式
* @param type 编码字符集,编码请求数据时用之,此参数为必填项(不能为""或null)
