Vuex操作中的Vue资源 - “this is null”错误

我正试图从商店行动中进行GET调用 . 但是我的 Vue.http.get() 电话会抛出 TypeError "this is null" .

我完全失去了，我还没有找到其他人在其他地方遇到这个具体问题 . 任何帮助，将不胜感激 . 谢谢

演练

• 用户导航到/ login /

• 提交登录

• 已通过身份验证和令牌

• 调度保存令牌和检索配置文件的操作

• 尝试使用 Vue.http 内部操作时发生错误

注意，令牌正确地存储在state和localStorage中 .

Login.vue

methods: {
    submit() {
        this.$http.post(
            this.loginEndpoint,
            this.object
        ).then(response => {
            this.$store.dispatch({
                "type": "auth/save",
                "token": response.body.key,
            }).then(() => {
                this.$router.push({name: "home"})
            }).catch(error => {
                console.log(error)
            })
        }).catch(error => {
            console.log(error)
        })
    }
}

商店

import Vue from 'vue'
import Vuex from 'vuex'
import Auth from '../stores/auth.js'


// plugins
Vue.use(Vuex)


export default new Vuex.Store({
    modules: {
        auth: Auth,
    },
})

auth.js - 存储模块

import Vue from 'vue'


export default {
    namespaced: true,

    state: {
        token: null,
        profile: {},
    },

    mutations: {
        setProfile(state, payload) {
            state.profile = payload.profile
        },

        setToken(state, payload) {
            state.token = payload.token
        },
    },

    actions: {
        save: (context, payload) => {
            return new Promise((resolve, reject) => {
                const url = "/rest-auth/user/"

                context.commit('setToken', {
                    token: payload.token,
                })

                localStorage.setItem("token", payload.token)

                console.log("get user profile")

                // *** Error below calling Vue.http.get ***
                // TypeError: this is null
                Vue.http.get(url).then(response => {
                    console.log("Profile received")

                    context.commit('setProfile', {
                        profile: response.body,
                    })

                    localStorage.setItem("profile", response.body)
                    resolve()

                }).catch(error => {
                    reject(error)
                })
            })
        },
    },
}
