我使用RNFetchBlob将图像从本地(ios)文件系统上传到Firebase
虽然我的图片正在被删除,但关闭后我的blob仍保留在文件系统中。 我尝试取消链接blob,但它仍然是
function createBlob(uri, mediaType) {
const Blob = RNFetchBlob.polyfill.Blob;
const typePrefix = isImage(mediaType) ? 'image' : 'video';
window.Blob = Blob;
window.XMLHttpRequest = RNFetchBlob.polyfill.XMLHttpRequest;
return new Promise((resolve, reject) => {
const uid = guid();
const mediaRef = firebase.storage().ref('users').child(`${uid}.${mediaType}`);
let uploadBlob = null;
Blob.build(uri, { type: `${typePrefix}/${mediaType}` })
.then((blob) => {
uploadBlob = blob;
return mediaRef.put(blob, { type: `${typePrefix}/${mediaType}` });
})
.then((response) => {
uploadBlob.close();
resolve(response);
})
.catch(error => {
reject(error);
});
});
}
关闭blob后,它在我的模拟器文件夹中的显示方式
createBlob
后我使用RNFetchBlob.fs.unlink(path)
答案 0 :(得分:2)
我认为您close()
正在工作,因为uploadBlob
变量是在前一个闭包中创建的,但未传递到下一个.then
块。我认为这可能有用......
Blob.build(uri, { type: `${typePrefix}/${mediaType}` })
.then((blob) => {
uploadBlob = blob;
return ({
response: mediaRef.put(blob, { type: `${typePrefix}/${mediaType}` }),
blob: uploadBlob
})
.then(({response, blob}) => {
blob.close();
resolve(response);
})
