1 | 后续修复： 2 | 1、后端修改: 3 | uvicorn.run(app,host='0.0.0.0',port=8888) 4 | 2、前端.env文件修改： 5 | VUE_APP_NAME=FastAPI 6 | VUE_APP_DOMAIN_DEV=192.168.1.101:8888 7 | （这里的192.168.1.101是本机局域网IP地址，FastAPI是希望显示的title） 8 | 3、nginx的nginx.conf修改： 9 | listen 80; 10 | server_name 192.168.1.101; 11 | 4、前端使用nodejs进行npm run build（或cnpm run build）打包。 12 | 5、删掉原来nginx里面的dist文件夹，并且拷贝刚打包的dist文件夹。 13 | 6、重启nginx和后端FastAPI 14 | 达到效果： 15 | 1、页面标题正常显示标题 16 | 2、局域网内其它电脑或手机可以正常访问和登录
