react-native-fetch-blob - 'react-native-fs' 和 'react-native-fetch-blob' 找不到下载的文件

Question

我使用'react-native-fs'和'react-native-fetch-blob'在android模拟器中测试文件下载，控制台显示下载成功，但我找不到文件在我的模拟器文件中系统，或者可能没有成功下载，谁能告诉我怎么办，谢谢

Answer 1

将此功能用于带有react-native-fetch-blob.

它对我有用，下载的文件将放在设备/模拟器的下载目录中。

function downloadFile(url,fileName) {
  const { config, fs } = RNFetchBlob;
  const downloads = fs.dirs.DownloadDir;
  return config({
    // add this option that makes response data to be stored as a file,
    // this is much more performant.
    fileCache : true,
    addAndroidDownloads : {
      useDownloadManager : true,
      notification : false,
      path:  downloads + '/' + fileName + '.pdf',
    }
  })
  .fetch('GET', url);
}
