我尝试将图片上传到firebase存储并从firebase存储中检索图像。但是,“检索”案例不起作用:
// image upload
var storageRef = firebase.storage().ref('profilePicturesOfAbmin/original/'+file.name);
storageRef.put(file);
function error(err) {
console.log("error",err);
}
// retrieve image from firebase storage
var storageRef = firebase.storage().ref();
var spaceRef = storageRef.child('profilePicturesOfAbmin/original/'+file.name);
storageRef.child('profilePicturesOfAbmin/original/'+file.name).getDownloadURL().then(function(url) {
console.log("bsbdsbsdbd");
var test = url;
alert("hfdghjghj",url);
}).catch(function(error) { });

因此,看到您的错误消息,想法是todo
StorageRef.put(file, function(){
// Now do the download
})
或者有一个等待文件上传的处理程序

您可能想尝试这样的事情......
var storageRef = firebase.storage().ref(filePath);
function uploadImage(event){
var file = event.target.files[0];
return storageRef.put(file).then(function(snapshot) {
// put the file now do something...
var fullPath = snapshot.metadata.fullPath;
console.log(fullPath);
}).catch(function(error){
console.log("error uploading "+error);
});
}
function retrieveImage(imageUri, imgElement){
if (imageUri.startsWith('gs://')) {
storageRef.refFromURL(imageUri).getMetadata().then(function(metadata) {
imgElement.src = metadata.downloadURLs[0];
console.log("URL is "+metadata.downloadURLs[0]);
}).catch(function(error){
console.log("error downloading "+error);
});
}
}
一旦文件成功上传,这将使用Promise来执行操作。
发生错误时,它也会登录到控制台。

var storageRef = firebase.storage().ref('profilePicturesOfAbmin/original/')
storageRef.listAll().then(res => {
//for folders
res.perfixes.forEach(folder => {
console.log(folder);
});
// for files NAME and URL
res.items.forEach(item => {
// console.log( item.name );
item.getDownloadURL().then(function (url) {
console.log(url);
});
});
})
