如何将图片上传到Firebase存储？ [英] How to upload an image to Firebase storage?
本文介绍了如何将图片上传到Firebase存储？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试将一个简单的字节数组上传到Firebase存储中，但是我的 onFailureListener 不断被调用并记录回给我，说上传失败。我希望你们可以告诉我我的代码有什么问题。
在上面我得到了
pre> // Firebase
私有Firebase mRef;
私有StorageReference storageRef;
然后在 onStart（）
@Override
保护无效onStart（）{
super.onStart（）;
googleApiClient.connect（）;
// Firebase
mRef =新的Firebase（链接到Firebase帐户）;
FirebaseStorage存储= FirebaseStorage.getInstance（）;
storageRef = storage.getReferenceFromUrl（link to storage）;
$ b $ p然后在我的 onActivityResult（） @Override
protected void onActivityResult（int requestCode，int resultCode，Intent data） {
addImageImageView.setVisibility（View.GONE）;
if（requestCode == Constants.REQUEST_CODE&& resultCode == RESULT_OK&& data！= null）{
//首先，我们必须确保将图像添加到
的ArrayList<图像> imagesFromGallery = data.getParcelableArrayListExtra（Constants.INTENT_EXTRA_IMAGES）;
for（int i = 0; i< imagesFromGallery.size（）; i ++）
{
try {
//尝试上传
InputStream stream = new FileInputStream（new File（imagesFromGallery.get（i）.path））;
StorageReference imageStorage = storageRef.child（cardImages /+testImages）;
UploadTask uploadTask = imageStorage.putStream（stream）;
uploadTask.addOnFailureListener（new OnFailureListener（）{
@Override
public void onFailure（@NonNull Exception e）{
Log.d（myStorage，failure :( ）;
}
}）。addOnSuccessListener（new OnSuccessListener< UploadTask.TaskSnapshot>（）{
@Override
public void onSuccess（UploadTask.TaskSnapshot taskSnapshot）{
Log.d（myStorage，success！）;
}
}）;
catch（UnsupportedEncodingException e）{
e.printStackTrace（）;
} catch（FileNotFoundException e）{
e.printStackTrace（）;
}
}
}
这是我的堆栈跟踪：

解决方案您需要登录用户或更改安全性允许公众访问。这在 Firebase存储安全的文档中有解释。
对于初始开发，您可以更改Firebase控制台中的规则以允许公开访问：
服务firebase.storage {
match /b/project-XXXXXXXXXXXXXX.appspot.com/o {
match / {allPaths = **} {
//提供对所有用户的访问
允许阅读：如果是真的;
允许写入：如果为true;
}
}
}
I'm trying to upload a simple byte array into Firebase storage, but my onFailureListener keeps getting called and logging back to me saying that the upload failed. I'm hoping you guys can tell me whats wrong with my code.
At the top I got
//Firebase
private Firebase mRef;
private StorageReference storageRef;
Then in onStart()
@Override
protected void onStart() {
super.onStart();
googleApiClient.connect();
//Firebase
mRef = new Firebase("link to firebase account");
FirebaseStorage storage = FirebaseStorage.getInstance();
storageRef = storage.getReferenceFromUrl("link to storage");
}
Then in my onActivityResult()
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
addImageImageView.setVisibility(View.GONE);
if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK && data != null) {
//First we gotta make sure to add the images to
ArrayList<Image> imagesFromGallery = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES);
for (int i = 0; i < imagesFromGallery.size(); i++)
{
try {
//try uploading it
InputStream stream = new FileInputStream(new File(imagesFromGallery.get(i).path));
StorageReference imageStorage = storageRef.child("cardImages/" + "testImages");
UploadTask uploadTask = imageStorage.putStream(stream);
uploadTask.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.d("myStorage","failure :(");
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Log.d("myStorage","success!");
}
});
catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
Here is my stack trace:
11-13 21:27:00.392 31388-996/com.daprlabs.aaron.swipedeck2 E/StorageException: StorageException has occurred.

解决方案 You either need to sign-in the user or change the security rules to allow public access. This is explained in the documentation for Firebase Storage Security.
For initial development, you can change the rules at the Firebase Console to allow public access:
service firebase.storage {
match /b/project-XXXXXXXXXXXXXX.appspot.com/o {
match /{allPaths=**} {
// Provide access to all users
allow read: if true;
allow write: if true;
}
}
}
