vue.config.js
const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
transpileDependencies: true,
devServer:{
proxy:{
'/api':{
target: 'http://xx.xx.xxx.xx',
changeOrigin:true,
pathRewrite: {
'^/api': ''
}
}
}
}
}) server: {
// 跨域的写法
proxy: {
'/api': {
target: 'http://nvzu.xxx.cn/', // 实际请求地址
changeOrigin: true,
rewrite: (path) => path.replace(/^\/api/, ""),
},
},
},
// 不跨域的写法
/* server: {
host: '192.168.1.195'
// 0.0.0.0
}, */"use strict";
import axios from "axios";
// Full config: https://github.com/axios/axios#request-config
axios.defaults.baseURL = '/api' || '';
// axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;
// axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
let config = {
// 这里的api就是获取configJS中的地址
baseURL: '/api'
// timeout: 60 * 1000, // Timeout
// withCredentials: true, // Check cross-site Access-Control
};
const _axios = axios.create(config);
_axios.interceptors.request.use(
function(config) {
// Do something before request is sent
return config;
},
function(error) {
// Do something with request error
return Promise.reject(error);
}
);
// Add a response interceptor
_axios.interceptors.response.use(
function(response) {
// Do something with response data
return response;
},
function(error) {
// Do something with response error
return Promise.reject(error);
}
);
export default{
install:function(app){
app.config.globalProperties.axios = _axios;
app.config.globalProperties.$translate = (key) =>{
return key
}
}
}
/* Plugin.install = function(Vue) {
Vue.axios = _axios;
window.axios = _axios;
Object.defineProperties(Vue.prototype, {
axios: {
get() {
return _axios;
}
},
$axios: {
get() {
return _axios;
}
},
});
};
Vue.use(Plugin)
export default Plugin; */页面使用proxy.axios.get/post进行获取跨域接口
<template>
<div class="home">
<img alt="Vue logo" src="../assets/logo.png">
<HelloWorld msg="Welcome to Your Vue.js App"/>
</div>
</template>
<script>
import {getCurrentInstance} from 'vue' // 引入Vue3中的getCurrentInstance
// @ is an alias to /src
import HelloWorld from '@/components/HelloWorld.vue'
export default {
name: 'HomeView',
mounted(){
const {proxy} = getCurrentInstance();
console.log(proxy);
// Axios.get
proxy.axios.get('/index_category/data').then((e)=>{
console.log(e);
})
},
components: {
HelloWorld
}
}
