React native App reagiert nicht auf meine lokale .net -API ⇐ C#

[Guest]

Leute, ich fange gerade an, mit React Native zu arbeiten, und ich habe viele Dinge ausprobiert, die es mit .NET -API funktionieren lassen, aber wenn es eine Get -Anfrage über Emulator sendet, heißt es: "Netzwerkanforderung fehlgeschlagen". . Ich habe alles tief gegoogelt, aber es gibt keine Lösung, sondern holt anstelle meiner lokalen IP "10.0.2.2". Was habe ich falsch gemacht oder was habe ich verpasst?

Code: Select all

async function getAll() {
console.warn('getAll');
return fetch('https://10.0.2.2:5001/api/Users/getall')
.then(response => response.json().data)
.then(response => console.log(response))
.catch(error => console.error(error));
}

const App: () => Node = () => {
const [users, setUsers] = useState(getAll());

return (

 (
{item.userName}
)}
renderSectionHeader={({section}) => (
{section.title}
)}
keyExtractor={(item, index) => index}
/>

);
};

export default App;
