修改nuxt.config.ts：

export default defineNuxtConfig({   .....   //跨域处理   nitro: {     devProxy: {       "/api": {         target: process.env.NUXT_KINGBAL_PROXY_PATH,    // 目标后端API地址         changeOrigin: true,         rewrite: (path) => path.replace(/^\/api/, ''),       },     },   },  ..... })

如上所述，直接在nuxt.config.ts中添加跨域处理部分即可~~~

正式环境的时候我们也需要服务器支持跨域，我们直接配置nginx即可：

 server {         listen       80;         server_name  www.178xyw.com;          location / {             proxy_pass http://localhost:6666/;             add_header 'Access-Control-Allow-Origin' '*';             add_header 'Access-Control-Allow-Credentials' 'true';             add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';             add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';         }            error_page   500 502 503 504  /50x.html;         location = /50x.html {             root   html;         }     }

其中 www.178xyw.com 需要变更为你的绑定域名
