Question

我正在尝试让我的Vue-Router记住输入URL，并在登录后转到那里。这段代码在无限循环中结束时一直有效，直到倒数next()为止，而我不知道为什么。

在下面的代码中，我在<----- why infinite loop (?)处添加了注释，我也尝试过next({ fullPath: url})，即使我检查并将entryUrl设置为测试条目{{1， }}

示例路径：

/requests

beforeEach块：

  {
    path: "/requests",
    name: "My Requests",
    component: Requests,
    meta: { requiresAuth: true },
  },

通过无限循环，我的意思是它会执行此操作，直到遇到“最大调用堆栈大小超出”错误为止。这些值只是控制台日志：

let entryUrl = null;

router.beforeEach((to, from, next) => {
  let locStorage = JSON.parse(localStorage.getItem("userData"));
  let stateStore = state.getters.getUserData;
  let userData = locStorage || stateStore;
  let isAuthenticated = userData.token !== "" && userData.token !== undefined;

  // if entry url not "/login" or "/" set entryUrl
  if (to.fullPath !== "/login" && to.fullPath !== "/") {
    entryUrl = to.fullPath;
  }

  // if path requires auth
  if (to.matched.some((record) => record.meta.requiresAuth)) {
    if (!isAuthenticated) {
      // needs auth, none found, send to "/login"
      next({ name: "Login" });
    } else {
      // needs auth, has auth, check for entryUrl
      let url = entryUrl ? entryUrl : "/";
      entryUrl = null;
      next(url); // <-------------------------- why infinite loop (?)
    }
  } else {
    // no auth required ("/login" only in my case)
    next();
  }
});

export default router;
