vue打包使用Nginx代理解决跨域问题

这篇文章主要为大家详细介绍了vue打包使用Nginx代理解决跨域问题，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随四海网的小编两巴掌来看看吧！

vue 在开发环境，涉及跨域，就在本地配置了代理，但是部署到服务器上，就不行了。

解决方法有一下几种

• 服务器端配置CORS
• 用nginx反向代理,和访问本地服务器是一样的
• 可以修改成正式线上的地址，再build

推荐

使用nginx配置反向代理，这样就可以在前端彻底解决跨域问题。

vue index.js文件源码

代码如下：

'use strict'
// Template version: 1.2.7
// see http://vuejs-templates.github.io/webpack for documentation.
const path = require('path')
module.exports = {
dev: {
// Paths

assetsPublicPath: '/',
changeOrigin: true,
proxyTable: {
'/api': {
target: 'https://api.it120.cc/fengyu',
changeOrigin:true,
pathRewrite: {
'^/api': ''
}
},
'/book': {
target: 'http://api.zhuishushenqi.com/',
changeOrigin:true,
pathRewrite: {
'^/book': ''
}
},
},

// 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,
},
build: {
// Template for index.html
index: path.resolve(__dirname, '../dist/index.html'),
// Paths
assetsRoot: path.resolve(__dirname, '../dist'),
assetsSubDirectory: './static',
assetsPublicPath: './',

*/
productionSourceMap: true,
// https://webpack.js.org/configuration/devtool/#production
devtool: '#source-map',
// Gzip off by default as many popular static hosts such as
// Surge or Netlify already gzip all static assets for you.
// Before setting to `true`, make sure to:
// npm install --save-dev compression-webpack-plugin
productionGzip: false,
productionGzipExtensions: ['js', 'css'],
// Run the build command with an extra argument to
// View the bundle analyzer report after build finishes:
// `npm run build --report`
// Set to `true` or `false` to always turn it on or off

}
}
