vue:登录后跳转到之前要访问的页面(vue@3.3.4)

一，安装pinia

liuhongdi@lhdpc:/data/vue/responsive$ npm -S install pinia

安装完成后查看已安装的版本:

liuhongdi@lhdpc:/data/vue/responsive$ npm list pinia
responsive@0.1.0 /data/vue/responsive
└── pinia@2.1.6

二，代码：

1,store/redirect.js

import {defineStore} from 'pinia'
//保存登录后要跳转到的页面
export const useRedirectStore = defineStore("REDIRECT",{
    state() {
        return {
            redirectUrl: '',
        }
    },
    //getter
    getters: {
 
    },
    //actions
    actions: {
        setRedirectUrl(url) {
            console.log("set redirecturl:");
            this.redirectUrl = url;
        }
    }
})

2,无权登录时转到登录页

//跳转到登录页
let redistr = useRouter().currentRoute.value.fullPath;
let path = useRouter().currentRoute.value.path;
if (path != '/login/login') {
    //保存登录后要跳转的url
    let storer = useRedirectStore();
    storer.setRedirectUrl(redistr);
}
 
//跳转到登录页
router.push({
  path: "/login/login"
});

3,登录成功后的跳转:

let url = "/api/login/login";
axios({
  method:"post",
  url:url,
  data:postData,
  headers:{'Content-Type': 'multipart/form-data'},
}).then((res) => {
      if (res.data.code == 0) {
          ElMessage.success("登录成功!");
          setUser(res.data);
 
       //执行登录成功后需要执行的跳转
 
          let storer = useRedirectStore();
    //判断要跳转到的地址
    let {redirectUrl} = storeToRefs(storer);
    if (redirectUrl == '') {
        router.replace({path: "/index/home"});
    } else {
       let url = "/#"+redirectUrl.value;
       //清空
       storer.setRedirectUrl('');
       //跳转
       location.href=url;
    }
 
      } else {
        ElMessage.error("error:"+res.data.msg);
      }
    }
).catch(err=>{
  console.log(err);
  alert('网络错误:'+err.message);
});

三，测试效果:
