在UniApp的开发小程序过程中,为了针对不同角色用户登录后的个性化需求。通过动态权限配置机制,能够根据用户的角色展示不同的TabBar。此项目是通过Uni-App命令行的方式搭建的
Vue3+Vite+Ts+Pinia+Uni-ui
的小程序项目
1、司机角色:
2、供应商角色:
3、司机且供应商角色:
tabbar
组件,在需要显示tabbar的页面添加这个组件,在根据一个选中的index值来切换选中效果。而我的实现方式:把所有有
tabbar
的页面全部引入在一个tabbarPage
页面,根据角色userType
,来动态显示页面
1、常规登录:通过微信登录获取code
2、根据code获取openId
3、根据openId获取token,若token存在表:此用户已经登陆/绑定过,则根据token获取用户信息,根据角色直接进入项目页面;若token不存在,则跳转到登录页面
4、登录成功后,调用用户信息接口,根据角色直接进入项目页面
export const useLogin = () => {
const { proxy } = getCurrentInstance() as any
//常规登录
const judgmentLogin = () => {
uni.login({
provider: 'weixin', //使用微信登录
success: async (loginRes) => {
// 根据微信登录的code获取openid
const res = await proxy.$api.getOpenid({ code: loginRes.code })
if (res.success) {
// console.log('res.data.openid----', res.data.openId)
// 根据openid获取token
openidLogin(res.data.openId)
// 存储openid
uni.setStorageSync('openId', res.data.openId)
}
}
});
}
// 登录过的用户再次进入根据openid获取token,有token则直接进入当前用户的页面,没有则进入登录页面
const openidLogin = (async (openId: string) => {
// console.log('openId----', openId)
const res = await proxy.$api.openIdLogin({ openId })
if (res.success) {
if (res.data) {
// 存储token
uni.setStorageSync('token', res.data)
userInfo(openId)
} else {
uni.navigateTo({
url: '/pages/login/login'
})
}
}
})
// 登录成功后(有token后)根据openid获取用户信息
const userInfo = (async (openId: any) => {
const res = await proxy.$api.getUserInfo({ openId })
if (res.success) {
console.log('获取登陆用户信息', res.data)
uni.setStorageSync('userInfo', JSON.stringify(res.data))
const userTypeList = ['scm_driver', 'scm_supplier', 'supplier_and_driver']
// 遍历角色数组来存储当前用户的角色。此角色为userTypeList中的某一个并且此数组只能存在一个userTypeList里面的角色,不会同时存在两个
res.data.roles.map((item: any) => {
if (userTypeList.includes(item.roleKey)) {
uni.setStorageSync('userType', item.roleKey)
}
})
// 判断角色数组中只要有一个角色在userTypeList中,则进入当前用户的角色页面,否则进入无权限页面
const flag = res.data.roles.some((item: any) => {
return userTypeList.includes(item.roleKey)
})
// console.log('flag----', flag)
if (flag && userTypeList.includes(uni.getStorageSync('userType'))) {
setTimeout(() => {
uni.reLaunch({
url: '/pages/tabbarPage/tabbarPage'
})
}, 500)
} else {
uni.showToast({
icon: 'none',
title: '当前用户角色没有权限!'
})
}
}
