JS 下载文件 后端返回url，前端重命名文件

cont CommonDownloadFile = (blobUrl, name) => {
	const fileName = name;
	const x = new window.XMLHttpRequest();
	x.open("GET", blobUrl, true);
	x.responseType = "blob"
	x.onload = () => {
		const url = window.URL.createObjectURL(x.response);
		const a = document.createElement("a");
		a.href = url;
		a.download = fileName;
		document.body.appendChild(a); // 兼容低版本浏览器
		a.click();
	}
	x.send();
}
