解决跨域访问。需要在UserController类上加上@CrossOrigin注解
package com.qfedu.fmmall.controller;
import com.qfedu.fmmall.service.UserService;
import com.qfedu.fmmall.vo.ResultVO;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;
@ResponseBody
@Controller
@RequestMapping("/user")
@Api(value="提供用户的登录和注册接口",tags="用户管理")
@CrossOrigin
public class UserController {
@Resource
private UserService userService;
@ApiOperation("用户登录接口")
@ApiImplicitParams({
@ApiImplicitParam(dataType = "string",name = "username",value="用户登录账号",required = true),
@ApiImplicitParam(dataType = "string",name = "password",value="用户登录密码",required = true)
})
@RequestMapping(value = "/login",method= RequestMethod.GET)
public ResultVO login(@RequestParam("username") String name,@RequestParam(value="password") String pwd){
ResultVO resultVO = userService.checkLogin(name, pwd);
return resultVO;
}
@ApiOperation("用户注册接口")
@ApiImplicitParams({
@ApiImplicitParam(dataType = "string",name = "username",value="用户注册账号",required = true),
@ApiImplicitParam(dataType = "string",name = "password",value="用户注册密码",required = true)
})
@PostMapping( "/regist")
public ResultVO regist(String username,String password){
return userService.userRegist(username,password);
}
}
账号，密码校检代码
<script type="text/javascript">
$("#submitBtn").click(function(){
//1.接收账号和密码
var name=$("#userName").val();
var pwd=$("#userPwd").val();
//2.进行数据的合法性校验
if(name.length<8||name.length>20){
$("#tips").html("<label style='color:red'>账号长度必须为8-20个字符</label>")
}else{
if(pwd.length<8||pwd.length>16){
$("#tips").html("<label style='color:red'>密码长度必须为8-16个字符</label>")
}else{
$.get("http://localhost:8080/user/login",{username:name,password:pwd},function(res){
console.log(res);
if(res.code==10000){
window.location.href="index.html";//跳转到index.html页面
}else{
$("#tips").html("<label style='color:red'>"+res.msg+"</label>");
}
},"json")
}
}
});
</script>
前端页面cookie传值
var userInfo=res.data;
document.cookie="username="+userInfo.username;
document.cookie="userImg"+userInfo.userImg;
window.location.href="index.html";
cookie_utils.js
var operator="="
function getCookieValue(keyStr){
var value=null;
var s=window.document.cookie;
var arr=s.split("; ");
var keyStr;
var value;
for(var i=0;i<arr.length;i++){
var str=arr[i];
var k=str.split("=")[0];
var v=str.split("=")[1];
if(k==keyStr){
value=v;
break;
}
}
return value;
}
function setCookieValue(key,value){
document.cookie=key+operator+value;
}
index.html
<script type="text/javascript" src="static/js/cookie_utils.js"></script>
<script type="text/javascript">
var name=getCookieValue("username");
var img=getCookieValue("userimg");
console.log(name);
console.log(img);
</script>
改进前端页面cookie传值
引入
login.html
<script type="text/javascript" src="static/js/cookie_utils.js"></script>
var userInfo=res.data;
//document.cookie="username="+userInfo.username;
//document.cookie="userImg"+userInfo.userImg;
setCookieValue("username",userInfo.username);
setCookieValue("userimg",userInfo.userImg);
登录后控制台显示
