网络请求失败

我尝试允许端口连接由sudo ufw允许使用任何端口命令，但无济于事

fetch('http://192.XXXXXX//form/user_registration.php',
        {
            method: 'POST',
            headers:
            {
                'Accept': 'application/json',
                'Content-Type': 'application/json',
            },

网络请求失败

我通过在电脑和手机上建立相同的连接来解决了这个问题在USB收集的帮助下，我在两边都获得了相同的IP，而且我还必须更改端口号，因为这两个本地服务器不会互相冲突...

首先，在笔记本电脑或PC中找到您的IP地址：

Mac：https://osxdaily.com/2010/11/21/find-ip-address-mac/

Windows：https://www.whatismyip.com/how-to-get-your-local-ip-address-on-windows-10/

Linux：https://opensource.com/article/18/5/how-find-ip-address-linux

然后，在尝试将Expo客户端连接到本地服务器时，请使用http://localhost:8000而不是http://YourIPAddress:8000。
