响应本机博览会客户端的网络请求失败 [英] network request failed in react native expo client

问题描述

网络请求失败

我试过允许端口连接通过 sudo ufw 允许任何端口命令，但它没有帮助

I have tried allowing port to connect by sudo ufw allow to any port command but it is not helping

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

推荐答案

我通过在我的电脑和手机上使用相同的连接解决了这个问题在usb tathering的帮助下，我在两边得到了相同的ip，而且我也必须更改我的端口号，因为两个本地服务器不会相互冲突...
