利用proxy 解决 Django Vue 开发环境中的跨域问题 最近使用 Django+Vue的组合快速的做一个项目，前段之前有看过，但是只是👀会了，这次实际操作，在前后端分离后的开发环境中踩了坑。 环境 Django + DRF Django Channels，主要是websocket vue-admin-template，一个开源的项目，很多东西都有实现，新手可以用来改改就用，还能学习 开发环境： wsgi, 8000 asgi, 8001 vue, 9528 问题 想像在使用nginx一样的透明的使用开发环境 django已经配置了corsheaders middleware了 尝试 axios显示指定地址和端口到8000的服务上，解决了axios实例的访问，但是使用 el-upload的表单时，发现就不好使了，localhost和其他不同域，拿不到 cookie中的csrftoken，导致被 django拒绝 解决 在查看了各种文档后，最有效的方案是devServer的proxy，这是webpack提供的功能，使用的是http-proxy-middleware这个中间件，文档很详细，可以看看。 目标： 代理 /api的请求到8000端口的wsgi server 代理 /ws的请求到8001的asgi server /api ---> localhost:8000/api localhost:9528 (cookie) -- /ws ---> localhost:8001/ws vue.conf.js devServer: { ... proxy: { [process.env.VUE_APP_BASE_API]: { target: 'http://127.0.0.1:8000', changeOrigin: true, ws: false, pathRewrite: { ['^' + process.env.VUE_APP_BASE_API]: '' }, cookieDomainRewrite: { '*': 'localhost' } }, '/ws': { target: 'ws://127.0.0.1:8001', // changeOrigin: true, secure: false, ws: true } } ... } 说明： ...
