无法在react-native中通过axios将Image附加到数组的特定索引处，并使用formdata进行post

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

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

const uploadImageToServer = (imageUri, index) => {
  return new Promise((resolve, reject) => {
    const data = new FormData();
    const imagePath = imageUri.replace('file://', '');

    data.append('index', index);
    data.append('image', {
      uri: imagePath,
      type: 'image/jpeg',
      name: 'image.jpg',
    });

    RNFetchBlob.fetch('POST', 'http://your-server-url.com/upload', {
      'Content-Type': 'multipart/form-data',
    }, data)
      .then((response) => {
        resolve(response);
      })
      .catch((error) => {
        reject(error);
      });
  });
};

const imageUri = 'file:///path/to/image.jpg';
const index = 0;

uploadImageToServer(imageUri, index)
  .then((response) => {
    console.log('Image uploaded successfully:', response);
  })
  .catch((error) => {
    console.error('Image upload failed:', error);
  });
