BUG场景
一个前后端分离的项目，前端使用Vue2框架，后端使用FastAPI，前端想要传输图片给后端，使用的相关接口为：
'http://10.96.67.161:8081/uploadImg/'
后端FastAPI运行的代码为：
if __name__ == '__main__':
uvicorn.run(app="main:app", host="localhost", port=8081, reload=True)
前端控制台发生报错：
POST http://10.96.67.161:8081/uploadImg/ net::ERR_CONNECTION_REFUSED
解决方案
修改后端代码的localhost为本机IP：
if __name__ == '__main__':
uvicorn.run(app="main:app", host="10.96.67.161", port=8081, reload=True)
