React Native Expo如何使用expo图像拾取器将图像上传到Firebase

npm install expo-image-picker firebase

import * as ImagePicker from 'expo-image-picker';
import * as firebase from 'firebase';

const pickImage = async () => {
  let result = await ImagePicker.launchImageLibraryAsync({
    mediaTypes: ImagePicker.MediaTypeOptions.Images,
    allowsEditing: true,
    aspect: [4, 3],
    quality: 1,
  });

  if (!result.cancelled) {
    uploadImage(result.uri);
  }
};

const uploadImage = async (uri) => {
  const response = await fetch(uri);
  const blob = await response.blob();

  const ref = firebase.storage().ref().child('images/' + Date.now());
  const snapshot = await ref.put(blob);

  // 获取上传后的图像URL
  const downloadURL = await snapshot.ref.getDownloadURL();

  // 在此处可以对上传后的图像进行进一步处理或展示
  console.log('Image uploaded successfully:', downloadURL);
};
