项目中发现使用HTTPClient的PostMethod方法有乱码，尝试使用
1、post参数设置
method.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET,"utf-8");
2、client设置
client.getParams().setContentCharset("UTF-8");
client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
3、设置postmethod请求头
method.addRequestHeader("Content-type","application/x-www-form-urlencoded; charset=UTF-8");
