HttpClient3 POST的中文编码问题

在用到HttpClient的基本请求和响应时候，发现默认的编码是“ISO-8859-1 ”，这样就存在中文乱码问题了，解决办法如下，记录一下：

三种形式：

postMethod.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET,  " UTF-8 " );
        postMethod.addRequestHeader( " Content-Type " , " text/html;charset=UTF-8 " );
        postMethod.setRequestHeader( " Content-Type " ,  " text/html;charset=UTF-8 " );
