Flex 與 Java servlet 串在一起(傳參數篇)

今天我要介紹如何透過HttpService的方式將Flex製作的會員註冊表單資料送出至Servlet，最後再將資料存至db

1.首先我們先用Flex拉一個表單如下圖，接著編輯MXML加入HttpService與將物件標上id

以下是code的部分，看的方法用顏色一樣的表示有關聯~~紅色部分表示您要傳資料至url的設定，其他就對照顏色看嚕


-------------------------------MXML---------------------------------

//基本上這個httpEncoding是為了傳網頁中文參數所以需先encoding
private function httpEncoding(param:String):String{
return encodeURIComponent(param);
}

private function insert_data():void{

var params:URLVariables = new URLVariables();
//塞你要傳的值給params變數
params.member_name = httpEncoding(this.member_name.text);
params.member_sex= httpEncoding(this.member_sex.selectedValue.toString());
params.member_birthday= httpEncoding(this.member_birthday.text);
//post至servlet
add_to_servlet.send(params);
}


-------------------------------MXML---------------------------------


2.撰寫Servlet端


---------------------------------------------JAVA Servlet-----------------------------------------
public class FlexServlet extends HttpServlet{

private static final long serialVersionUID = 1L;

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
doPost(request,response);
}

public void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.setContentType("text/xml;charset=utf-8");
resp.setHeader("Cache-Control", "no-cache");

String action = req.getParameter("action");
System.out.println("action:"+action);
if(action.equals("member_list")){
doQueryMemberList(req,resp);
}else if(action.equals("member_add")){
doInsertMember(req,resp);
}
}
private void doInsertMember(HttpServletRequest req,HttpServletResponse resp){
String member_name=URLDecoder.decode(req.getParameter("member_name"));
String member_sex=URLDecoder.decode(req.getParameter("member_sex"));
String member_birthday=URLDecoder.decode(req.getParameter("member_birthday"));
}

---------------------------------------------JAVA Servlet-----------------------------------------

這樣您就可以在java上進行db的新增與修改資料嚕....db那段有需要我在補上嚕.....
