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

const uploadImageToS3 = () => {
  // 使用react-native-image-picker选择图像
  ImagePicker.showImagePicker({}, (response) => {
    if (response.didCancel) {
      console.log('用户取消了图像选择');
    } else if (response.error) {
      console.log('图像选择错误:', response.error);
    } else {
      // 创建FormData对象来存储图像数据
      const formData = new FormData();
      formData.append('file', {
        uri: response.uri,
        type: response.type,
        name: response.fileName,
      });

      // 发送POST请求到S3预签名URL
      axios.post('YOUR_S3_PRE_SIGNED_URL', formData)
        .then((res) => {
          console.log('图像上传成功:', res);
        })
        .catch((error) => {
          console.log('图像上传失败:', error);
