一、在使用vue開發的時候常常要涉及到跨域的問題,其實在vue cli中是有咱們設置跨域請求的文件的。css
二、當跨域沒法請求的時候咱們能夠修改工程下config文件夾下的index.js中的dev:{}部分。
dev: {vue
env: require('./dev.env'), port: 8080, autoOpenBrowser: false, assetsSubDirectory: '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 }
將target設置爲咱們須要訪問的域名。webpack
三、而後在main.js中設置全局屬性:git
Vue.prototype.HOST = '/api'
四、至此,咱們就能夠在全局使用這個域名了,以下:github
var url = this.HOST + '/movie/in_theaters' this.$http.get(url).then(res => { this.movieList = res.data.subjects; },res => { console.info('調用失敗'); });
