axios可以解决跨域访问的问题吗？

1、在使用vue开发的时候经常要涉及到跨域的问题，其实在vue cli中是有我们设置跨域请求的文件的。2、当跨域无法请求的时候我们可以修改工程下config文件夹下的index.js中的dev:{}部分。dev: {    env: require('./dev.env'),    port: 8080,    autoOpenBrowser: false,    assetsSu

bDirectory: 'static',    assetsPublicPath: '/',    proxyTable: {        '/api': {            target: 'http://api.douban.com/v2',            changeOrigin: true,            pathRewrite: {                '^/api': ''            }        }    },    // CSS Sourcemaps off by default because relative paths are "buggy"    // with this option, according to the CSS-Loader README    // (https://github.com/webpack/css-loader#sourcemaps)    // In our experience, they generally work as expected,    // just be aware of this issue when enabling this option.    cssSourceMap: false}将target设置为我们需要访问的域名。3、然后在main.js中设置全局属性：Vue.prototype.HOST = '/api'4、至此，我们就可以在全局使用这个域名了，如下：var url = this.HOST + '/movie/in_theaters'    this.$http.get(url).then(res => {      this.movieList = res.data.subjects;    },res => {      console.info('调用失败');
    });
5、一定要重新启动服务
