vue-axios：无法读取未定义的属性'post'

我试图使用axios发送登录数据，但我收到了以下错误：

[Vue warn]：v-on处理程序出错："TypeError:无法读取属性未定义的"post"；

TypeError:无法读取未定义的属性"post">

我使用了这个$文档中的http.post。

main.js

import Vue from "vue";
import App from "./App.vue";
import axios from "axios";
import VueAxios from "vue-axios";
import router from "./router/router";
import store from "./store/index";
import vuetify from "./plugins/vuetify";
Vue.config.productionTip = false;
Vue.use(VueAxios, axios);
new Vue({
router,
store,
vuetify,
render: h => h(App)
}).$mount("#app");

Vue.use(Vuex);
export default new Vuex.Store({
