Vue+flask realizes video synthesis function (drag and drop upload)

let files = this.fileList;
let formd = new FormData();
let i = 1;

//Add upload list files.forEach(item => {

	i++;
})
formd.append("type", i)
let config = {
	headers: {
		"Content-Type": "multipart/form-data"
	}
}

//Upload file request axios.post("/qwe", formd, config).then(res => {
	console.log(res.data)
})

@app.route("/file",methods=['POST'])
