Servlet获取Ajax POST数据乱码的一种解法

Servlet获取Ajax POST数据乱码的一种解法

1. 对中文参数编码encodeURI(chinesePara);
  poststr = "username="+encodeURI("中文");

2.服务器端获取参数后解码

String username = new String(request.getParameter("username").getBytes("ISO-8859-1"),"UTF8");  

  -----------------------------------------------------------

  http_request.open("POST", url, true);
  http_request.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
  http_request.send(poststr);
