我正在尝试将（Laravel API）与（React 本机应用程序）连接，我在邮递员中测试了 API，它 100% 正常工作，但是当我在本机应用程序中获取时，出现以下错误！

错误

    [Unhandled promise rejection: TypeError: Network request failed]
- node_modules\whatwg-fetch\dist\fetch.umd.js:527:17 in setTimeout$argument_0
- node_modules\react-native\Libraries\Core\Timers\JSTimers.js:135:14 in _callTimer

在应用程序中，它显示如下：

有我的 app.js 代码（只有 fetch 函数）：

myfun = async()=>{

await fetch('http://127.0.0.1:8000/api/login',{

    method:'POST',
    headers:{
        'Accept': 'application/json',
        'Content-Type': 'application/json'
    },
    body: JSON.stringify({"email":email, "password": passowrd})
}).then(res => res.json())
.then(resData =>{
    alert(resData);
    console.log(resData);
});
}
