我拥有并发布了新的 Firebase Storage SDK，即 10.2.6。当我尝试下载文件时出现此错误。以前在 10.2.1 中我没有问题。

就在崩溃之前，我得到了这个信息:

I/DynamiteModule: Selected remote version of com.google.android.gms.firebasestorage, version >= 6

编辑:

当然是这里:

private void handleDownload(final String key, ArrayList<String> locations, ArrayList<Talk> talks) {
        for (String location : locations) {
            DatabaseH.getShareTalksReference().child(key).child(location).setValue(null);
        }


        int[] downloadCount = {talks.size()};
        log.d(downloadCount);

        for (final Talk talk : talks) {
            new StorageListener(StorageH.getStream(talk.getPath()), (task) -> {
                try {
                    File file = new File(sTalksFolder, talk.getFileName());
                    talk.setPath(file.getAbsolutePath());

                    InputStream inputStream = task.getResult().getStream();
                    String fileContent = IOUtils.toString(inputStream);
                    TalkFile talkFile = new TalkFile(fileContent);
                    talkFile.setTalk(talk);

                    IOUtils.copy(IOUtils.toInputStream(talkFile.toString()), new FileOutputStream(file));

                    downloadCount[0]--;

                    if (downloadCount[0] == 0) {
                        ReceivedDB.getInstance(context).deleteReceived(locations);
                        SendMessagingService.received(getApplicationContext(), locations);
                        FileSyncService.addFiles(getBaseContext(), talks);
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            });
        }
    }

这是 getStream() 方法:

public static StreamDownloadTask getStream(String url) {
        return FirebaseStorage.getInstance().getReferenceFromUrl(url).getStream();
}

最佳答案

我知道这已经有一段时间了，但如果有人得到这个，我为解决这个问题所做的只是修改访问该项目的规则

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}

我认为默认情况下它希望对用户进行身份验证，但出于开发目的，我删除了该 if 语句。您可以在存储部分下的规则选项卡中找到它
