我想实现以下流程:
当http请求正在进行时,显示加载程序。请求完成后隐藏加载程序。

我不确定我是否理解你,但我假设那样。当http请求正在进行时你想要一个加载器。所以我要展示逻辑。希望理解
<template>
<div>
<div v-if="loading">
<!-- here put a spinner or whatever you want to do when request is on proccess -->
</div>
<div v-if="!loading">
<!-- here is your application code -->
</div>
</div>
</template>
<script>
import axios from 'axios'
export default {
data() {
return {
loading: false
}
},
methods: {
makeRequest () {
this.loading = true //the loading begin
axios.get('/example')
.then(response => {
this.loading = false //the loading stop when the response given from server
//do whatever with response
})
.catch(error => {
this.loading = false
//do whatever with response
})
}
}
}
</script>
希望你理解。有关信息,发送http请求我使用的是axios,我也在使用v-if,但在第二个div中你可以使用v-else

仅适用于Nuxt.js用户
roli编写的示例很好,但是理想情况下您不想在每次请求中重复自己。所以我建议你这样做 感谢:https://stackoverflow.com/a/58084093/1031297
添加['@ nuxtjs / axios']。...
添加或修改 plugins / axios.js
export default ({ app, $axios ,store }) => {
$axios.interceptors.request.use((config) => {
store.commit("SET_DATA", { data:true, id: "loading" });
return config;
}, (error) => {
return Promise.reject(error);
});
$axios.interceptors.response.use((response) => {
store.commit("SET_DATA", { data:false, id: "loading" });
return response;
}, (error) => {
return Promise.reject(error);
});
}
商店在
export default {
state: () => ({
loading: false
}),
mutations: {
SET_DATA(state, { id, data }) {
state[id] = data
}
},
actions: {
}
}
