# 一、跨平台授权登录的实现
要想实现项目A授权登录到项目B，必须满足以下几个条件: ①项目A 需要有 项目B 的token，将token作为url参数进行跳转； ②项目B 开放与 login 同级的路径，不做拦截； ③项目B 从url中获取token，写入浏览器 Cookies 后自动获取登陆信息，即可完成授权；
router/index.js
import Vue from "vue";
import Router from "vue-router";
/**
* 不需要登录拦截的路由配置
*/
const loginIgnore = {
names: ["404", "403"], // 根据路由名称匹配
paths: ["/login", "/authorization"], // 根据路由fullPath匹配
/**
* 判断路由是否包含在该配置中
* @param route vue-router 的 route 对象
* @returns {boolean}
*/
includes(route) {
return this.names.includes(route.name) || this.paths.includes(route.path);
}
};
/**
* 初始化路由实例
* @returns {VueRouter}
*/
function initRouter() {
return new Router({
mode: "history",
routes: [{
path: "/login",
name: "login",
meta: {
title: "登录"
},
component: () => {
return import("@/pages/login/LoginBlank");
}
},
{
path:"/start",
name:"start",
component: () => {
return import("@/pages/StartView");
}
},
{
path: "/authorization",
name: "authorization",
meta: {
title: "项目A授权登录项目B"
},
component: () => {
return import("@/pages/authorization/Authorization");
}
},
{
path: "/404",
name: "exp404",
meta: {
title: "404页面"
},
component: () => {
return import("@/pages/exception/404");
}
},
{
path: "/500",
name: "exp500",
meta: {
title: "500页面"
},
component: () => {
return import("@/pages/exception/500");
}
},
{
path:"*",
redirect: "/404"
}]
});
}
export {loginIgnore, initRouter};
