Question

是关于将图像上传到 Firebase 存储的 Blob 提取的教程。我完全像他那样做，但我的不起作用......请帮忙。

import * as firebase from 'firebase'


export let uploadImage = async (uri, imageName) => {  
    const resp = await fetch(uri);  //network [TypeError: Network request failed]
    console.log('resp:',resp)
    const blob = await resp.blob();    
    console.log('blob:',blob)
    let ref = firebase.storage().ref().child('eventapp/' + imageName)
    return ref.put(blob)
}
