download:post下载

本文写了一个ts封装的小方法，download下载功能的实现，
首先建立一个ts文件：

import axios from 'axios'
//post 下载
export const download = (url: string, obj: any, fileName: string, format: string): void => {
    axios.request({ method:'post', url: url, data: obj, responseType:'arraybuffer' }).then((response: any) => {
        let data: any = response.data
        if (!data) {
            return
        }
        let url = window.URL.createObjectURL(new Blob([data]))
        let link = document.createElement('a')
        link.style.display = 'none'
        link.href = url
        link.download = fileName + format; //下载后文件名
        link.setAttribute('download', fileName + format)
        document.body.appendChild(link)
        link.click()
    })
}

download = (url: string, obj: any, fileName: string, format: string): void
参数: {
url: 下载地址
obj: 参数对象
fileName: 文件名称
format: 下载的文件格式
}
eg: download(‘https://www.baidu.com/’, { id: 14138 }, ‘这是个文件’, ‘.txt’)
