网络请求失败-Expo React Native

Question

这真的很烦人。如果我使用http://my-domain.com其处理out网络请求失败，但是https://my-domain.com它不断给我网络请求失败的错误。

我一直在网上查找，但仍然没有解决这个问题。请帮忙。

获取代码

const [contents, setContents] = useState([]);
const fetchChannelContent = (slug) => {
fetch(Http.api+"/channel/"+slug)
.then((response) => response.json())
.then((json) => {
setContents(json.channel.content);
})
.catch((error) => {
console.error(error);
});
};
useEffect(() => {
fetchChannelContent(url)
}, []);[![enter image description here][1]][1]
