前端

后台
@RequestMapping("/login")
public String login(String name,String password){
User user = userService.login(name, password);
if(user!=null){
return "index";
}else{
return "redirect:/page";
}
}
@RequestMapping(value = "/getVerify")
public void getVerify(HttpServletRequest request, HttpServletResponse response) {
try {
response.setContentType("image/jpeg");
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expire", 0);
RandomValidateCodeUtil randomValidateCode = new RandomValidateCodeUtil();
randomValidateCode.getRandcode(request, response);
} catch (Exception e) {
logger.error("获取验证码失败", e);
}
}
@RequestMapping(value = "/checkVerify", method = RequestMethod.POST,headers = "Accept=application/json")
@ResponseBody
public boolean checkVerify(@RequestParam(required=false) String verifyInput, HttpSession session) {
try{
String inputStr = verifyInput;
String random = (String) session.getAttribute("RANDOMVALIDATECODEKEY");
if (inputStr == null) {
System.out.println(inputStr);
return false;
}
if (inputStr.equals(random)) {
System.out.println(inputStr);
return true;
} else {
System.out.println(inputStr);
return false;
}
}catch (Exception e){
logger.error("验证码校验失败", e);
return false;
}
}
这里的login方法得不到前端name和password的值怎么办
