前端权限设置

需求

family权限的用户不能访问doctor/*.html …

效果

访问doctor/*.html弹出“你不是医生账户”，
重定向到home.html

实现

获取到当前路径currentURL
获取到当前用户角色userRole
判断这个路径是否是该角色能访问的

function onload(){var currentURL = window.location.href;// console.log("当前页面路径是：" + currentURL);// console.log(userRole);var adminMatch = currentURL.match(/\/admin\//);if (adminMatch&&userRole!='admin'){alertBox("你不是管理员账户",function(){window.location.href="../home.html";});} var doctorMatch = currentURL.match(/\/doctor\//);if (doctorMatch&&userRole!='doctor'){alertBox("你不是医生账户",function(){window.location.href="../home.html";});} var familyMatch = currentURL.match(/\/family\//);if (familyMatch&&userRole!='family') {alertBox("你不是家属账户",function(){window.location.href="../home.html";});} }

资源

模块结构

具体的user.js实现

调用栈

$(document).ready(function () {set_login_status();{storage(result.data);{onload(userRole);}}
}

每一个页面都有这个的引入

<script src="./js/user.js"></script>

$(document).ready(function () {// 设置用户登录状态set_login_status();// 注销按钮单击事件$("#btn-logout").click(function (e) { logout();        });
});

function set_login_status() {var $A = $(".user-name");if (!$A) return false;$.ajax({type: "GET",url: SERVER_PATH + "/user/status",xhrFields: {withCredentials: true},success: function (result) {if (result.status == "0" && result.data) {$A.text(result.data.nickname);$("#user-info").show();$("#center").show();$("#register").hide();$("#login").hide();window.sessionStorage.setItem("id", result.data.userId);storage(result.data);// 根据用户的 userGroup 来设置跳转路径var centerLink;if (result.data.userGroup === "管理员") {centerLink = "./admin/center.html";} else if (result.data.userGroup === "医生") {centerLink = "./doctor/center.html";} else if(result.data.userGroup === "老人家属"){centerLink = "./family/center.html"; } else {centerLink = "./user/center.html"; // 默认路径}$("#center").attr("href", centerLink); // 设置跳转路径} else {$("#user-info").hide();$("#center").hide();$("#register").show();$("#login").show();}}});    
}

var userRole;//根据用户id查到用户组中返回 account 存入sessionStorage
function storage(user) {var id=user.userId;var token=sessionStorage.getItem("token");$.ajax({type: "GET",url: SERVER_PATH + "/user/account",data: {"userId":id,"token": token},xhrFields: {withCredentials: true},success: function (result) {if (result.status == "0" && result.data) {//存储Accountwindow.sessionStorage.setItem(result.data.type, result.data.account);if(result.data.type=='adminAccount'){userRole='admin';}else if(result.data.type=='doctorAccount'){userRole='doctor';}else if(result.data.type=='familyAccount'){userRole='family';}else if(result.data.type=='userAccount'){userRole='user';}onload(userRole);} }});    
}

function onload(){var currentURL = window.location.href;// console.log("当前页面路径是：" + currentURL);// console.log(userRole);var adminMatch = currentURL.match(/\/admin\//);if (adminMatch&&userRole!='admin'){alertBox("你不是管理员账户",function(){window.location.href="../home.html";});} var doctorMatch = currentURL.match(/\/doctor\//);if (doctorMatch&&userRole!='doctor'){alertBox("你不是医生账户",function(){window.location.href="../home.html";});} var familyMatch = currentURL.match(/\/family\//);if (familyMatch&&userRole!='family') {alertBox("你不是家属账户",function(){window.location.href="../home.html";});} }

后端权限控制

主要是依赖token得到用户信息
然后到拦截器进行验证

1.给所有前端请求都携带token

首先，怎么让每一个前端请求都携带token数据呢

在common.js中添加一下代码

// 设置全局AJAX参数
// 把token加入索引的请求中，后端会有权限验证
$.ajaxSetup({data: {"token": window.sessionStorage.getItem("token")}
});

这样就会使得所有前端请求都携带token数据呢

注意一点：用来在路径中直接携带token数据将会被影响

类似于一下这个

他会导致token变成复选框这样的请求

token=xxx,xxx

前端请求

后端响应：

如果是原先的data中请求还是有效的
只不过会覆盖原来的token

2.添加拦截器

package com.jsss.controller.Interceptor;import com.alibaba.fastjson.JSONObject;
import com.jsss.common.ErrorCode;
import com.jsss.common.ResponseModel;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;@Component
public class LoginCheckInterceptor implements HandlerInterceptor, ErrorCode {@Autowiredprivate RedisTemplate redisTemplate;@Overridepublic boolean preHandle(HttpServletRequest request,HttpServletResponse response, Object handler) throws Exception {String token = request.getParameter("token");if (token == null || StringUtils.isBlank(token) || !redisTemplate.hasKey(token)) {response.setContentType("application/json");response.setCharacterEncoding("utf-8");PrintWriter writer = response.getWriter();Map<Object, Object> data = new HashMap<>();data.put("code", USER_NOT_LOGIN);data.put("message", "请先登录！");ResponseModel model = new ResponseModel(ResponseModel.STATUS_FAILURE, data);writer.write(JSONObject.toJSONString(model));return false;}return true;}
}

3.配置到WebMvcConfiguration

package com.jsss.configuration;import com.jsss.controller.Interceptor.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;@Configuration
public class WebMvcConfiguration implements WebMvcConfigurer {@Autowiredprivate LoginCheckInterceptor loginCheckInterceptor;@Overridepublic void addInterceptors(InterceptorRegistry registry) {//登录拦截器配置registry.addInterceptor(loginCheckInterceptor).addPathPatterns("/**").excludePathPatterns("/user/login", "/user/register"/*,"/{path}/captcha"*/);}}

4.更多的权限验证

后端配置拦截器的一个问题【问题】
