Vue如何跨域请求

配置config/index.js

proxyTable: {
        "/api":{
            target:'https://api.douban.com/v2/',
            changeOrigin:true,
            pathRewrite:{
                "^/api":'/'
            }
        }
    },

在main.js中，写入请求的地址

Vue.prototype.$host="/api";

组件中使用

let url=this.$host+'/movie/top250';
        this.$axios.get(url,{
          params:{
            count:10,
            start:0
          }
        })
        .then(res=>{
          console.log(res)
        })
        .catch(error=>{
          console.log(error)
        })
