在vite.config.ts中用环境变量设置proxy

import { fileURLToPath, URL } from 'node:url'
import { defineConfig, loadEnv } from 'vite'
import vue from '@vitejs/plugin-vue'
import vueJsx from '@vitejs/plugin-vue-jsx'
import VueDevTools from 'vite-plugin-vue-devtools'

// https://vitejs.dev/config/
export default defineConfig(({ mode, command }) => {
  const env = loadEnv(mode, process.cwd()); //一定要加上
  return {
    plugins: [
      vue(),
      vueJsx(),
      VueDevTools(),
    ],

    server: {
      host: '0.0.0.0',
      proxy: {
        [env.VITE_APP_BASE_API]: {
          target: `http://172.16.16.7:8088`,
          changeOrigin: true,
          rewrite: (path) => path.replace(RegExp(`^${env.VITE_APP_BASE_API}`), ''),
          bypass(req, res, options: any) {
            const proxyURL = options.target + options.rewrite(req.url);
            console.log('proxyURL', proxyURL);
            req.headers['x-req-proxyURL'] = proxyURL; // 设置未生效
            res.setHeader('x-res-proxyURL', proxyURL); // 设置响应头可以看到
          },
        },
      }
    },
    resolve: {
      alias: {
        '@': fileURLToPath(new URL('./src', import.meta.url))
      }
    }
  }
})
