AJAX 乱码 针对 GET 和 POST

GET 和 POST 的要分开处理.

AJAX请求  

 

		function httpGet(param) {
			var req = getXMLRequest();
			req.open("GET", "sql.jsp?" + param, true);
		  	req.onreadystatechange = handleResponse;
		  	req.send();		
		}
		
		function httpPost(param) {
			var req = getXMLRequest();
			req.open("POST", "sql.jsp", true);
			req.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;");
		  	req.onreadystatechange = handleResponse;
		  	req.send(param);		
		}

 

服务器端处理

	if(request.getMethod().equals("GET")) {
		sql = request.getParameter("sql");
		sql = new String(sql.getBytes("ISO8859-1"));
	} else if (request.getMethod().equals("POST")) {
		request.setCharacterEncoding("UTF-8");
		sql = request.getParameter("sql");
	} else {
		return;
	}
