本文介绍了vue下跨域设置的相关介绍，分享给大家，具体如下:
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。
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
}
'/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：
4、至此，我们就可以在全局使用这个域名了，如下：
{
this.movieList = res.data.subjects;
},res => {
console.info('调用失败');
});
