Firebase存储10.2.6->无法打开结果流 [英] Firebase Storage 10.2.6 -> Could not open resulting stream

问题描述

我拥有新的Firebase Storage SDK(即10.2.6)并遇到了问题.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.

I have and issue with the new Firebase Storage SDK, namely 10.2.6. When I try do download a file I get this error. Previously in the 10.2.1 I had no problem.

就在坠机事故发生之前，我得到了以下信息:

Just before the crash I get this info:

I/DynamiteModule: Considering local module com.google.android.gms.firebasestorage:0 and remote module com.google.android.gms.firebasestorage:6
I/DynamiteModule: Selected remote version of com.google.android.gms.firebasestorage, version >= 6

当然是这样:

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:

This is the getStream() method:

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

推荐答案

我知道这已经有一段时间了，但是如果有人知道了，我为解决此问题所做的只是修改访问该项目的规则

I know this has been out for a while, but if anyone gets this, what I did to resolve this issue is just modifying the rule for accessing the item

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，但是出于开发目的，我删除了if语句.您可以在存储"部分下的规则"标签中找到此图片

I think by default it wants the user to be authenticated, but for dev purposes I removed that if statement. You'll find this in the rules tab under the storage section
