// Get the uploaded files. If you want to limit the number of files uploaded, you can // let files = [...this.$refs.fileInput.files].splice(0,limit);
// You can also throw a prompt here that the number of files exceeds the limit let files = [...this.$refs.fileInput.files];

return;
}
// Backend interface address let url = `url`;
// Request the backend interface together Promise.all(
files.slice(0, files.length).map((file) => {
const data = new FormData();
data.append('file', file);
return request.post(url, data, {
