如何在react native中从api下载文件( excel )？

npm install react-native-fetch-blob --save

import RNFetchBlob from 'react-native-fetch-blob';

const downloadFile = () => {
  const fileUrl = 'https://example.com/api/download/excel';
  const fileDir = RNFetchBlob.fs.dirs.DownloadDir;
  const fileName = 'example.xlsx';

  RNFetchBlob.config({
    fileCache: true,
    addAndroidDownloads: {
      useDownloadManager: true,
      notification: true,
      path: `${fileDir}/${fileName}`,
      description: 'Downloading file...',
    },
  })
    .fetch('GET', fileUrl)
    .then((res) => {
      console.log('File downloaded successfully.');
    })
    .catch((error) => {
      console.log('Error downloading file:', error);
    });
};

<Button title="Download Excel" onPress={downloadFile} />
