前台请求
$.ajax({
url : '/turn',
type : "post",
data : {
"userName":userName,
"userPass":userPass
},
async : false,
success : function(data) {
}
});
java后台接收数据
方法一：
public String getData(HttpServlettRequest request){
String ss= request.getParameter(“xxx”); //ss=>xx
}
方法二：
public String getData(){
HttpServletRequest request= ServletActionContext.getRequest();
String ss = request.getParameter("xxx"); //ss=>xx
}
方法三：
需要Spring mvc
后端通过 @RequestParam(value=”xxx”) String xxx 分别获取对应的键值对
@RequestMapping(value="/turn", method=RequestMethod.GET)
public @ResponseBody String emrSubmit(@RequestParam(value="username") String username，@RequestParam(value="userpass") String pass){
}
方法四：
需要Spring mvc
后端通过 @RequestParam Map <String,Object> param 一次性获取全部的键值对
@RequestMapping(value="/turn", method=RequestMethod.GET)
public @ResponseBody String emrSubmit(@RequestParam Map<String,Object> param){
String id = (String)params.get("username");
String pwd= (String)params.get("userpass");
}
