vue下载blob流乱码

下载blob流乱码主要原因是因为blob流不能放在axios的header里面而是放在外面

                _this.$send.get({
                    url: '/attendance/exportExcelTemplate',
                    responseType: 'blob',
                    headers: {
                        Accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
                        'Content-Type': 'application/json; charset=UTF-8',
                        'Accept-Encoding': 'gzip, deflate',
                    }
                }, res => {
                    const blob = new Blob([res], {type: 'application/vnd.ms-excel;charset=utf-8;'})
                    let url = window.URL.createObjectURL(blob)
                    const fileName = 'attendanceTemplate.xlsx'
                    const elink = document.createElement('a')
                    elink.download = fileName
                    elink.style.display = 'none'
                    elink.href = window.URL.createObjectURL(blob)
                    document.body.appendChild(elink)
                    elink.click()
                    // window.open(url)
                    URL.revokeObjectURL(elink.href) // 释放URL 对象
                    document.body.removeChild(elink)
                })

                _this.$send.post({
                    url: '/attendance/exportExcel',
                    responseType: 'blob',
                    headers: {
                        Accept: 'application/ms-excel',
                        'Content-Type': 'application/json;charset=UTF-8',
                    },
                    data: data
                }, res => {
                    const blob = new Blob([res], {type:"application/vnd.ms-excel"})
                    console.log(blob)
                    const fileName = 'attendanceTemplate.xlsx'
                    const elink = document.createElement('a')
                    elink.download = fileName
                    elink.style.display = 'none'
                    elink.href = window.URL.createObjectURL(blob)
                    document.body.appendChild(elink)
                    elink.click()
                    URL.revokeObjectURL(elink.href) // 释放URL 对象
                    document.body.removeChild(elink)


                });

而关键点就是axios里面要这样放在外面

    axios({
        method: defaults.method,
        url: defaults.url,
        data: defaults.method === 'POST' || defaults.method === 'PUT' ? defaults.data : null,
        params: defaults.method === 'GET' || defaults.method === 'DELETE' ? defaults.data : null,
        headers: defaults.headers,
        baseURL: defaults.baseURL,
        responseType: defaults.responseType,//这个network里面header是找不到的这才是对的
   
    })
