如何将React-Native-camera拍摄的图像上传到Firebase存储？

import React, { useState } from 'react';
import { View, Button } from 'react-native';
import { RNCamera } from 'react-native-camera';
import firebase from 'firebase';

// 初始化Firebase
firebase.initializeApp({
  // Firebase配置信息
});

const UploadImage = () => {
  const [imageData, setImageData] = useState(null);

  // 拍摄图像并上传到Firebase存储
  const handleTakePicture = async () => {
    if (this.camera) {
      const options = { quality: 0.5, base64: true };
      const data = await this.camera.takePictureAsync(options);
      setImageData(data.base64);

      // 初始化存储引用
      const storageRef = firebase.storage().ref();

      // 创建Blob对象
      const blob = await new Promise((resolve, reject) => {
        const xhr = new XMLHttpRequest();
        xhr.onload = function () {
          resolve(xhr.response);
        };
        xhr.onerror = function (e) {
          console.log(e);
          reject(new TypeError('Network request failed'));
        };
        xhr.responseType = 'blob';
        xhr.open('GET', data.uri, true);
        xhr.send(null);
      });

      // 上传图像到Firebase存储
      const uploadTask = storageRef.child('images/' + data.fileName).put(blob);

      // 监听上传任务状态变化
      uploadTask.on(
        'state_changed',
        (snapshot) => {
          // 上传进度
          const progress = (snapshot.bytesTransferred / snapshot.totalBytes) * 100;
          console.log('Upload is ' + progress + '% done');
        },
        (error) => {
          // 上传错误处理
          console.log(error);
        },
        () => {
          // 上传完成，获取下载URL
          uploadTask.snapshot.ref.getDownloadURL().then((downloadURL) => {
            console.log('File available at', downloadURL);
            // 可以在这里进行下载URL的处理，例如展示图像或者其他操作
          });
        }
      );
    }
  };

  return (
    <View style={{ flex: 1 }}>
      <RNCamera
        ref={(ref) => {
          this.camera = ref;
        }}
        style={{ flex: 1 }}
        type={RNCamera.Constants.Type.back}
        captureAudio={false}
      />
      <Button title="拍摄并上传" onPress={handleTakePicture} />
    </View>
  );
};

export default UploadImage;
