vue 项目webpack proxyTable只是用于开发环境吗？现在代码在开发环境不跨域，打包到线上竟然跨域了，怎么搞

1 现在开发环境没有使用proxyTable解决跨域，是后台php解决的，
2 在开发环境的时候没有跨域 ，npm run build 打包放到服务器上运行 ，接口就跨域了

这样可以在前端设置什么解决吗

单纯前端解决不了吧，我记得proxytable本身只是为了开发时使用的，他本身是处理了跨域的一些问题的。你在build之后就和他没关系了，相当于只是一个js去执行。
不知道你前端页面是用什么起的服务，如果是用的nginx的话，可以在里面做一个反向代理。在不就是通过服务端做CORS了。
