vue axios 下载excel

1. 封装的接口api方法

 exportCoil(responseType:any) {
    return REST.request(HTTPMethod.GET,  `${this.url}/ExportCoilData`,responseType)
 }

2. 组件中调用

		exportExcel() {
			this.coilAPI?.exportCoil('blob').then((res: any) => {
				var blob = new Blob([res.data], {
					type: "application/x-msdownload;charset=UTF-8"
				})
				let url = window.URL.createObjectURL(blob)
				let link = document.createElement('a')
				link.style.display = 'none'
				link.href = url
				link.id = 'Adownload'
				//命名可能会出现问题，格式一定和后端下载的格式一样
				link.setAttribute('download', `铝卷数据_ ${AiDateTime.YMD(new Date())}.xlsx`)
				document.body.appendChild(link)
				link.click()
			})
		}
