AxiosError：React Native 在向本地后端发出 api 请求时出现网络错误

Question

Frontend

await axios.get("http://localhost:8000/admin/api/getcategories",{
            "Content-Type": "application/json",
          }).then(result=>{
            console.log(result);
        }).catch(err=>{
            console.log(err);
        })

Backend

const cors = require('cors');

app.use(cors());

Tried restarting the application, and with other api tried sending without headers, but nothing worked, also added

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

for android and NSAllowsArbitraryLoads for IOS

Try to use ngrok ( https://ngrok.com/ ) to make your local API public. It is free for developers
