前言

上一篇已经创建好了前后端项目，本篇开始编码部分。

开始

几乎所有的系统都绕不开登录功能，那么就从登录开始，完成用户登录以及用户菜单权限控制。

登录

首先用户输入账号密码点击登录，然后组合以下参数调用identityserver的/connect/token端点获取token：

{grant_type: "password",scope: "HelloAbp",username: "",password: "",client_id: "HelloAbp_App",client_secret: "1q2w3e*"
}

这个参数来自ABP模板的种子数据：

我使用的是password flow，这个flow无需重定向。如果你的网站应用只有一个的话，可以这么做，如果有多个的话建议采用其他oidc方式，把认证界面放到identityserver程序里，客户端重定向到identityserver去认证，这样其实更安全，并且你无需在每个客户端网站都做一遍登录界面和逻辑。。。

还有一点，严格来说不应该直接访问/connect/token端点获取token。首先应该从identityserver发现文档/.well-known/openid-configuration中获取配置信息，然后从/.well-known/openid-configuration/jwks端点获取公钥等信息用于校验token合法性，最后才是获取token。ABP的Angular版本就是这么做的，不过他是使用angular-oauth2-oidc这个库完成，我暂时没有找到其他的支持password flow的开源库，参考：https://github.com/IdentityModel/oidc-client-js/issues/234

前端想正常访问接口，首先需要在HttpApi.Host，IdentityServer增加跨域配置：

前端部分需要修改的文件太多，下面只贴出部分主要代码，需要完整源码的可以去GitHub拉取。

src\store\modules\user.js：

const clientSetting = {grant_type: "password",scope: "HelloAbp",username: "",password: "",client_id: "HelloAbp_App",client_secret: "1q2w3e*"
};
const actions = {// user loginlogin({ commit }, userInfo) {const { username, password } = userInforeturn new Promise((resolve, reject) => {clientSetting.username = username.trim()clientSetting.password = passwordlogin(clientSetting).then(response => {const data = responsecommit('SET_TOKEN', data.access_token)setToken(data.access_token).then(() => {resolve()})}).catch(error => {reject(error)})})},// get user infogetInfo({ commit }) {return new Promise((resolve, reject) => {getInfo().then(response => {const data = responseif (!data) {reject('Verification failed, please Login again.')}const { name } = datacommit('SET_NAME', name)commit('SET_AVATAR', '')commit('SET_INTRODUCTION', '')resolve(data)}).catch(error => {reject(error)})})},setRoles({ commit }, roles) {commit('SET_ROLES', roles)},// user logoutlogout({ commit, dispatch }) {return new Promise((resolve, reject) => {logout().then(() => {commit('SET_TOKEN', '')commit('SET_NAME', '')commit('SET_AVATAR', '')commit('SET_INTRODUCTION', '')commit('SET_ROLES', [])removeToken().then(() => {resetRouter()// reset visited views and cached views// to fixed https://github.com/PanJiaChen/vue-element-admin/issues/2485dispatch('tagsView/delAllViews', null, { root: true })resolve()})}).catch(error => {reject(error)})})},// remove tokenresetToken({ commit }) {return new Promise(resolve => {commit('SET_TOKEN', '')commit('SET_NAME', '')commit('SET_AVATAR', '')commit('SET_INTRODUCTION', '')commit('SET_ROLES', [])removeToken().then(() => {resolve()})})}
}

src\utils\auth.js：

export async function setToken(token) {const result = Cookies.set(TokenKey, token);await store.dispatch("app/applicationConfiguration");return result;
}export async function removeToken() {const result = Cookies.remove(TokenKey);await store.dispatch("app/applicationConfiguration");return result;
}

src\api\user.js：

export function login(data) {return request({baseURL: "https://localhost:44364",url: "/connect/token",method: "post",headers: { "content-type": "application/x-www-form-urlencoded" },data: qs.stringify(data),});
}export function getInfo() {return request({url: "/api/identity/my-profile",method: "get",});
}export function logout() {return request({baseURL: "https://localhost:44364",url: "/api/account/logout",method: "get",});
}

src\utils\request.js：

service.interceptors.request.use((config) => {// do something before request is sentif (store.getters.token) {config.headers["authorization"] = "Bearer " + getToken();}return config;},(error) => {// do something with request errorconsole.log(error); // for debugreturn Promise.reject(error);}
);// response interceptor
service.interceptors.response.use((response) => {const res = response.data;return res;},(error) => {console.log("err" + error); // for debugMessage({message: error.message,type: "error",duration: 5 * 1000,});if (error.status === 401) {// to re-loginMessageBox.confirm("You have been logged out, you can cancel to stay on this page, or log in again","Confirm logout",{confirmButtonText: "Re-Login",cancelButtonText: "Cancel",type: "warning",}).then(() => {store.dispatch("user/resetToken").then(() => {location.reload();});});}return Promise.reject(error);}
);

菜单权限

vue-element-admin的菜单权限是使用用户角色来控制的，我们不需要role。前面分析过，通过/api/abp/application-configuration接口的auth.grantedPolicies字段，与对应的菜单路由绑定，就可以实现权限控制了。

src\permission.js：

router.beforeEach(async (to, from, next) => {// start progress barNProgress.start();// set page titledocument.title = getPageTitle(to.meta.title);let abpConfig = store.getters.abpConfig;if (!abpConfig) {abpConfig = await store.dispatch("app/applicationConfiguration");}if (abpConfig.currentUser.isAuthenticated) {if (to.path === "/login") {// if is logged in, redirect to the home pagenext({ path: "/" });NProgress.done(); // hack: https://github.com/PanJiaChen/vue-element-admin/pull/2939} else {//user nameconst name = store.getters.name;if (name) {next();} else {try {// get user infoawait store.dispatch("user/getInfo");store.dispatch("user/setRoles", abpConfig.currentUser.roles);const grantedPolicies = abpConfig.auth.grantedPolicies;// generate accessible routes map based on grantedPoliciesconst accessRoutes = await store.dispatch("permission/generateRoutes",grantedPolicies);// dynamically add accessible routesrouter.addRoutes(accessRoutes);// hack method to ensure that addRoutes is complete// set the replace: true, so the navigation will not leave a history recordnext({ ...to, replace: true });} catch (error) {// remove token and go to login page to re-loginawait store.dispatch("user/resetToken");Message.error(error || "Has Error");next(`/login?redirect=${to.path}`);NProgress.done();}}}} else {if (whiteList.indexOf(to.path) !== -1) {// in the free login whitelist, go directlynext();} else {// other pages that do not have permission to access are redirected to the login page.next(`/login?redirect=${to.path}`);NProgress.done();}}
});

src\store\modules\permission.js：

function hasPermission(grantedPolicies, route) {if (route.meta && route.meta.policy) {const policy = route.meta.policy;return grantedPolicies[policy];} else {return true;}
}export function filterAsyncRoutes(routes, grantedPolicies) {const res = [];routes.forEach((route) => {const tmp = { ...route };if (hasPermission(grantedPolicies, tmp)) {if (tmp.children) {tmp.children = filterAsyncRoutes(tmp.children, grantedPolicies);}res.push(tmp);}});return res;
}const state = {routes: [],addRoutes: [],
};const mutations = {SET_ROUTES: (state, routes) => {state.addRoutes = routes;state.routes = constantRoutes.concat(routes);},
};const actions = {generateRoutes({ commit }, grantedPolicies) {return new Promise((resolve) => {let accessedRoutes = filterAsyncRoutes(asyncRoutes, grantedPolicies);commit("SET_ROUTES", accessedRoutes);resolve(accessedRoutes);});},
};

src\router\index.js：

export const asyncRoutes = [{path: '/permission',component: Layout,redirect: '/permission/page',alwaysShow: true, // will always show the root menuname: 'Permission',meta: {title: 'permission',icon: 'lock',policy: 'AbpIdentity.Roles'},children: [{path: 'page',component: () => import('@/views/permission/page'),name: 'PagePermission',meta: {title: 'pagePermission',policy: 'AbpIdentity.Roles'}},{path: 'directive',component: () => import('@/views/permission/directive'),name: 'DirectivePermission',meta: {title: 'directivePermission',policy: 'AbpIdentity.Roles'}},{path: 'role',component: () => import('@/views/permission/role'),name: 'RolePermission',meta: {title: 'rolePermission',policy: 'AbpIdentity.Roles'}}]},。。。。。。// 404 page must be placed at the end !!!{ path: '*', redirect: '/404', hidden: true }
]

因为菜单太多了，就拿其中的一个“权限测试页”菜单举例，将它与AbpIdentity.Roles绑定测试。

运行测试

运行前后端项目，使用默认账号admin/1q2w3E*登录系统：

正常的话就可以进入这个界面了：

目前可以看到“权限测试页”菜单，因为现在还没有设置权限的界面，所以我手动去数据库把这条权限数据删除，然后测试一下：

但是手动去数据库改这个表的话会有很长一段时间的缓存，在redis中，暂时没去研究这个缓存机制，正常通过接口修改应该不会这样。。。

我手动清理了redis，运行结果如下：

最后

本篇实现了前端部分的登录和菜单权限控制，但是还有很多细节问题需要处理。比如右上角的用户头像，ABP的默认用户表中是没有头像和用户介绍字段的，下篇将完善这些问题，还有删除掉vue-element-admin多余的菜单。
