当遇到中文的时候,不是所有的中文都需要UrlEncoded,
有的中文UrlEncoded反而不行,依照情况来定
httpost.setEntity(new UrlEncodedFormEntity(nvps,HTTP.UTF_8));
httpost.setEntity(new StringEntity(App2.entStr));
StringEntity stringEntity = new StringEntity(App2.entStr);
stringEntity.setContentEncoding("utf-8");
httpost.setEntity(stringEntity);
