如何使用FilePond上传图片？

<link href="https://unpkg.com/filepond/dist/filepond.css" rel="stylesheet">
<script src="https://unpkg.com/filepond/dist/filepond.js"></script>

<div id="filepond"></div>

const inputElement = document.getElementById('filepond');
const pond = FilePond.create(inputElement);

FilePond.setOptions({
  server: {
    url: '/upload',
    process: {
      headers: {
        'X-CSRF-TOKEN': 'token'
      }
    }
  }
});

pond.on('processfile', (error, file) => {
  if (!error) {
    console.log('文件已上传', file);
  } else {
    console.log('上传错误', error);
  }
});
