next.js 配置代理服务器（跨域问题）亲测有效

//next.config.js
/**
 * @type {import('next').NextConfig}
 */
const nextConfig = {
    async rewrites() {
        return [
            {
                source: '/api/:path*',
                destination: `http://localhost:5000/api/:path*`,
            },
        ];
    },
}
module.exports = nextConfig
