如何在React-native中将图片从图库复制到应用程序的安装目录

npm install react-native-fs --save

react-native link react-native-fs

import RNFS from 'react-native-fs';

import ImagePicker from 'react-native-image-picker';

const options = {
  title: 'Select Image',
  storageOptions: {
    skipBackup: true,
    path: 'images',
  },
};

ImagePicker.showImagePicker(options, (response) => {
  if (response.didCancel) {
    console.log('User cancelled image picker');
  } else if (response.error) {
    console.log('ImagePicker Error: ', response.error);
  } else if (response.customButton) {
    console.log('User tapped custom button: ', response.customButton);
  } else {
    const imagePath = response.uri;
    // 复制图片到应用程序的安装目录
    // 可以使用RNFS.copyFile方法将图片复制到指定目录
  }
});

const imagePath = response.uri;
const destinationPath = RNFS.DocumentDirectoryPath + '/image.jpg';

RNFS.copyFile(imagePath, destinationPath)
  .then(() => {
    console.log('Image copied to application directory');
  })
  .catch((error) => {
    console.log('Error copying image: ', error);
  });
