Question

我已经在我的Vue中存储了Laravel用户的状态，但是试图像这样获取它：

Traceback (most recent call last):
  File "script_2020-08-05-17-15-26.py", line 52, in <module>
    masked_df=source_df.withColumn("FirstName", fake_firstname())

    pickled_command, broadcast_vars, env, includes = _prepare_for_python_RDD(sc, command)

    raise pickle.PicklingError(msg)
_pickle.PicklingError: Could not serialize object: TypeError: can't pickle weakref objects

在控制台中调用该变量时，我得到：

ƒisLoggedIn（状态）{ 返回state.user？真假; }

代替let isLoggedIn = store.getters.isLoggedIn或true。

我的商店代码：

false

我的let store = { state: { user: '', }, mutations: { setAuthUser(state, user) { state.user = user; } }, getters: { isLoggedIn(state) { return state.user ? true : false } } }; export default store;，我在其中调用吸气剂：

app.js

您没有正确初始化存储，这导致了您注意到的问题。您的商店代码只是导出普通对象而不是Vuex.Store。

要初始化商店，请执行以下操作：

import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)

let store = /* ... */

export default new Vuex.Store(store)

从Vue中的商店获取吸气剂返回ƒisLoggedIn（状态）
