PHP结合vue导出excel出现乱码的解决方法分享

public static function phpExcelList($field, $list, $title='文件',$file_time){
        $spreadsheet = new Spreadsheet();
        $sheet = $spreadsheet->getActiveSheet();
        foreach ($list as $key => $value) {
            foreach ($field as $k => $v) {
                if ($key == 0) {
                    $sheet->setCellValue($k . '1', $v[1]);
                }
                $i = $key + 2; //表格是从2开始的
                $sheet->setCellValue($k . $i, $value[$v[0]]);
            }
        }
        
        ob_clean();
        header("Content-type:application/vnd.ms-excel;charset=UTF-8");
        header('Content-Type: application/vnd.ms-excel');
        header('Content-Disposition: attachment;filename="'.$title.'.csv"');
        header('Cache-Control: max-age=0');
        $writer = new Csv($spreadsheet);
        $writer->save('php://output');
        exit;
    }

this.$http.get(common.webapi+'/api/exportExcel',{params:{参数名称：参数值}}, {emulateJSON:true,responseType: 'blob'}).then((res)=>{
              if(res.data){
              const link = document.createElement('a');// 创建a标签
              let blob = new Blob(['\uFEFF' + res.data],{type: 'application/vnd.ms-excel;'}); // 设置文件类型并在返回值前加bom头，避免乱码
              link.style.display = "none";
              link.href = URL.createObjectURL(blob); // 创建URL
              link.setAttribute("download", "数据"+ this.$moment(new Date().getTime()).format("YYYY-MM-DD")+'.csv');
              document.body.appendChild(link);
              link.click();
              document.body.removeChild(link);
              //如果不会出现乱码，直接一句代码搞定：this.$fileDownload(res.data, "发票数据"+ this.$moment(new Date().getTime()).format("YYYY-MM-DD")+'.csv')
             }
           
          })
