Solution to the problem of vue2.0 axios cross-domain rendering
Below I will share with you a solution to the problem of vue2.0 axios cross-domain rendering. It has a good reference value and I hope it will be helpful to everyone.
(Scaffolding vue-cli used)
Step one: Use the following declaration in main.js
import axios from 'axios'; Vue.prototype.$axios=axios;
Then in other vue components you can call this.$axios and use
Step 2: Configure proxyTable(config in webpack index.js under)
dev:
{
加入以下
proxyTable:
{
'/api':
{
target:
'http://api.douban.com',//设置你调用的接口域名和端口号
别忘了加http
changeOrigin:
true,
pathRewrite:
{
'^/api':
'/'//这里理解成用‘/api'代替target里面的地址，后面组件中我们掉接口时直接用api代替
比如我要调用'http://api.douban.com/v2/movie/top250'，直接写‘/api/v2/movie/top250'即可
}
}
},##Step Three:
Try it, the cross-domain is successful, but please note that this is only a cross-domain problem solved in the development environment (dev). In the production environment, if it is actually deployed on the server, there will still be cross-domain problems if it is not from the same origin, as in our case The deployed server port is 3001, which requires front-end and back-end joint debugging. In the first step, we can test the front-end in two environments: production and development. In config/dev.env.js and prod.env.js, it is development/ In the production environment, configure the requested address API_HOST respectively. In the development environment, we use the proxy address api configured above. In the production environment, we use the normal interface address, so configure it like thismodule.exports = merge(prodEnv, {
NODE_ENV: '"development"',//开发环境
API_HOST:"/api/"
})module.exports = {
NODE_ENV: '"production"',//生产环境
API_HOST:'"http://api.douban.com"'
}instance.post(process.env.API_HOST+'user/login', this.form)
Step 4:
<template>
<p>
<ul>
<li v-for="item in movieArr">
<span>{{item.title}}</span>
</li>
</ul>
<button @click="sayOut">渲染</button>
</p>
</template>
<script>
export default {
data () {
return {
movieArr : []
}
},
methods: {
sayOut () {
this.$axios.get('/api/v2/movie/top250')
.then((response) => {
console.log(response.data.subjects)
this.movieArr = response.data.subjects // 这里要强调一下这个this 箭头函数指的是它的父级也就是vue实例 然后不用箭头函数的话 this是一个undefined 无法.movieArr来给他赋值 这里要注意一下 我被坑了半天 希望小伙伴不要被坑
})
}
}
}
</script>
