将接收到的文件上载到Firebase存储中
将接收到的文件上载到Firebase存储中
提问于 2022-05-08 17:52:07
在我的代码中，我从Firebase存储获得一个文件，并尝试将其上传到那里。
mStorageRef.child("write_but2.jpg").getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
mStorageRef.child("write_but3.jpg").putFile(uri);
}
});不起作用：
E/UploadTask: could not locate file for uploading:https://firebasestorage...
E/StorageException: StorageException has occurred.
An unknown error occurred, please check the HTTP result code and inner exception for server response.
Code: -13000 HttpResult: 0
No content provider: https://firebasestorage...
java.io.FileNotFoundException: No content provider: https://firebasestorage...请告诉我该怎么做？

这不是文档建议上传文件和读取下载URL的方式。为此，请使用以下代码行：
StorageReference ref = storageRef.child("images/write_but2.jpg");
Task uploadTask = ref.putFile(file);
Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
@Override
public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
if (!task.isSuccessful()) {
throw task.getException();
}
return ref.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
//Do what you need to do with the URL.
} else {
Log.d(TAG, task.getException().getMessage()); //Never ignore potential errors!
}
}

确保Firebase引用路径正确
// Create a storage reference from our app
StorageReference storageRef = storage.getReference();
// Create a reference with an initial file path and name
StorageReference pathReference = storageRef.child("images/stars.jpg");
pathReference.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
// Got the download URL for 'images/stars.jpg'
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception exception) {
// Handle any errors
}
