<button id="taozhi" type="submit">Convert</button>

function showAlert(event) {
// 这就是你需要的吧！！input.files获取选中文件之后的filelist
const input = document.querySelector('input[type="file"]')
const file = input.files[0]
let formData = new FormData();
formData.append('image', file);
fetch('http://localhost:8001/upload',{
method:'post',
body:formData,
})
.then((response) => response.json() )
.then((response)=>{
console.log(response)
})
.catch((err)=>console.error(err));
