使用vue+axios+vite实现跨域请求

1、route.js

import { createRouter, createWebHistory} from 'vue-router'

const routerHistory = createWebHistory()
const router = createRouter({
  history: routerHistory,
  routes
})
export default router;

2、main.js

import { createApp,h } from 'vue'
import router from './route/route'
import axios from "axios";
import VueAxios from 'vue-axios'

axios.defaults.headers.post['Content-Type']='application/json' const app = createApp(App) app.config.globalProperties.$axios = axios axios.defaults.withCredentials = true axios.defaults.baseURL = '/api'

app.use(VueAxios, axios)
app.use(router).use(ElementPlus).mount('#app')

3、vite.config.js

module.exports = {
    proxy: {
        '/api': {
            target: 'http://',  //你要跨域访问的网址
            changeOrigin: true,   // 允许跨域
            rewrite: (path) => path.replace(/^\/api/, '') // 重写路径把路径变成空字符
        }
    }
}

4、使用

this.$axios
    .post('/zentao/search-buildQuery', testData, {
      params: {
        zentaosid: this.sessionID,
      }
    })
    .then(res => {
      this.getOrderBugSearchList()
    }).catch(err => {
  console.log(err)
});
