权限受控的主体思路
我们已经做到了给用户分配角色,给角色分配权限,这个权限怎么和我们的路由以及左侧菜单结合起来呢(如何应用/生效)?
在权限管理页面中,每个路由都有一个标识,如果用户拥有这个标识,那么用户就可以访问这个路由模块,如果没有这个标识,就不能访问路由模块。
用什么来实现呢?
vue-router 提供了一个叫做 addRoutes 的 API 方法,这个方法的含义是动态添加路由规则,思路如下。

拆分静态和动态路由
- 从 constantRoutes 中删除动态路由 asyncRoutes,
src/router/index.js
。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
| export const asyncRoutes = [ departmentRouter, roleRouter, employeeRouter, permissionRouter, attendanceRouter, approvalRouter, salaryRouter, socialRouter ] export const constantRoutes = [ { path: '*', redirect: '/404', hidden: true } ]
|
- 先通过 addRoutes 添加所有的动态路由测试一下,
permission.js
。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
| import { asyncRoutes } from '@/router'
router.beforeEach(async function(to, from, next) { NProgress.start() if (store.getters.token) { if (to.path === '/login') { next('/') } else { if (!store.getters.userId) { await store.dispatch('user/getUserInfo') router.addRoutes(asyncRoutes) } next() } } })
|
测试:在地址栏输入对应的路由地址试试,例如 http://localhost:8888/#/permissions
。
问题:页面是能出来,刷新的时候为什么还是 404 了?
处理 404 问题
删除 router/index.js
中的 { path: '*', redirect: '/404', hidden: true }
路由配置项。
permission.js
。
1 2 3 4 5
| router.addRoutes([...asyncRoutes, { path: '*', redirect: '/404', hidden: true }])
|
问题:刷新的时候白屏了?
处理白屏问题
通过 addRoutes 动态新增的路由是异步的,不会即可生效,为了保证生效,需要让用户重新进一下首页(重新走一下 beforeEach 的逻辑)。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39
| import { asyncRoutes } from '@/router'
router.beforeEach(async function(to, from, next) { NProgress.start() if (store.getters.token) { if (to.path === '/login') { next('/') } else { if (!store.getters.userId) { await store.dispatch('user/getUserInfo') router.addRoutes([...asyncRoutes, { path: '*', redirect: '/404', hidden: true }]) next({ ...to, replace: true, }) return } next() } } })
|
筛选路由逻辑
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51
| router.beforeEach(async function(to, from, next) { NProgress.start() if (store.getters.token) { if (to.path === '/login') { next('/') } else { if (!store.getters.userId) { const { roles: { menus } } = await store.dispatch('user/getUserInfo') const filterRoutes = asyncRoutes.filter(item => menus.includes(item.children[0].name)) router.addRoutes([ ...filterRoutes, { path: '*', redirect: '/404', hidden: true } ]) next({ ...to, replace: true }) return } next() } } else { if (whiteList.indexOf(to.path) > -1) { next() } else { next('/login') } } NProgress.done() })
|
在地址栏手动输入筛选后的路由地址进行测试。
🤔 格外注意:需要把 router/modules
中每一个路由文件的 name 和后端返回的 menus 保持一致。
侧边栏的问题
问题:router.options.routes
只会拿到初始化时的 routes 规则,后续动态新增的拿不到。
思路:把动态路由也存储到 Vuex 一份,store/modules/user.js
。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
| import { constantRoutes } from '@/router' export default { namespaced: true, state: { token: getToken(), userInfo: {}, routes: constantRoutes || [] }, mutations: { setRoutes(state, filterRoutes) { state.routes = [...constantRoutes, ...filterRoutes, { path: '*', redirect: '/404', hidden: true }] } }, }
|
permission.js
。
1
| store.commit('user/setRoutes', filterRoutes)
|
- 建立获取 Vuex 中路由的快捷访问,
store/getters.js
。
1 2 3 4 5
| const getters = { routes: (state) => state.user.routes, } export default getters
|
- 通过 mapGetters 取出 routes,
layout/components/Sidebar/index.vue
。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
| <script> export default { components: { SidebarItem, Logo }, computed: { ...mapGetters(['sidebar', 'routes']),
}, } </script>
|
- 给另外一个账号分配权限测试。
员工 => 给“乔海”分配角色 => 角色 => 给角色分配权限 => 重新登录“乔海”的账号查看是否生效。
🤔 注意:后端对管理员的角色做了特殊处理,永远具有所有权限,所以请用其他账号测试。
- 新问题:通过浏览器地址栏手动输入的时候,发现竟能访问侧边栏没有的路由。
原因:因为我们前面在 addRoutes 的时候,一直都是往 router 实例添加,乔海受到了前面管理员的影响。
退出重置路由
目标
当多个账号相互切换时,处理 router 相互影响的问题。
内容
- 使用项目提供好的路由重置方法,
router/index.js
。
1 2 3 4 5
| export function resetRouter() { const newRouter = createRouter() router.matcher = newRouter.matcher }
|
- 重置路由实例和 Vuex 中的路由数据,
store/modules/user.js
。
1 2 3 4 5 6 7 8 9 10 11 12
| logout(context) { context.commit('removeToken') context.commit('removeUserInfo') resetRouter() context.commit('user/setRoutes', [], { root: true }) }
|
功能权限应用
- 封装自定义指令,
src/main.js
。
1 2 3 4 5 6 7 8 9 10 11
| Vue.directive('permission', { inserted(el, binding) { const points = store.state.user.userInfo?.roles?.points || [] if (!points.includes(binding.value)) { el.remove() } } })
|
- 应用自定义指令,
src/views/employee/index.vue
。
1
| <el-button v-permission="'add-employee'" size="mini" type="primary" @click="$router.push('/employee/detail')">添加员工</el-button>
|
首页-基本结构和数字滚动
- 安装数字滚动插件,
vue-count-to
。
- 基本结构,
src/views/dashboard/index.vue
。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440 441 442 443 444 445 446 447 448 449 450 451 452 453 454 455 456 457 458 459 460 461 462 463 464 465 466 467 468 469 470 471 472 473 474 475 476 477 478 479 480 481 482 483 484 485 486 487 488 489 490 491 492 493 494 495 496 497 498 499 500 501 502 503 504 505 506 507 508 509 510 511 512 513 514 515 516 517 518 519 520 521 522 523 524 525 526 527 528 529 530 531 532 533 534 535 536 537 538 539 540 541 542 543 544 545 546 547 548 549 550 551 552 553 554 555 556 557 558 559 560 561 562 563 564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579
