Hello, cocos developers!

I’m developing unzip function.

I’ve read this article.

So I’m using zip.js.

Here’s my code and screenshot of plugin.

        const zip = window["zip"];
        const zipReader = new zip.ZipReader(new zip.Uint8ArrayReader(binArray));
        const entries = await zipReader.getEntries();
        log(entries);
        if (entries.length > 0) {
          for (let i = 0; i < entries.length; i++) {
            const entry = entries[i];
            const data = await entry.getData(
              new zip.BlobWriter(zip.getMimeType(entry.filename))
            );
            log(entry.filename);
            const filePath = native.fileUtils.getWritablePath() + entry.filename;
            if (entry.compressionMethod == 0){ // directory
              if (!native.fileUtils.isDirectoryExist(filePath)) {
                native.fileUtils.createDirectory(filePath);
              }
            } else if (entry.compressionMethod == 8) { // file
              native.fileUtils.writeDataToFile(data, filePath);
            }
          }
        }

        await zipReader.close();
        zip.terminateWorkers();

Does no-worker mean it doesn’t work in web?

#4

Try clean your project, may be it cached. I have test on cocos creator 3.7.2 it work with both web and native. “zip-no-worker-inflate” mean decompress without using webworker (cocos native doesn’t have WebWorker). You can see describe in here: https://github.com/gildas-lormeau/zip.js/blob/master/dist/README.md

I enabled zip-no-worker-inflate, and disabled other plugin.
Build again for windows.
Clean in Visual Studio, and debug, same error.
Could you send your test project please?

#6

May you doesn’t have this script config:
zip.configure({
useWebWorkers: false
});

Try add this on before extract zip

#7
