背景
以我个人证书为例，购买后服务商会提供注册机构的证书凭证，证书凭证效果如下。
腾讯云域名管理列表（https://console.cloud.tencent.com/domain/all-domain） 如果管理的域名比较多，又希望批量下载证书时就比较麻烦，因为当前产品功能并未提供批量下载功能。所以今天分享一下，如果来批量下载证书凭证列表。
如何批量下载域名证书文件
介绍一下如何通过脚本批量下载证书文件。 首先打开证书下载页，将证书页的cookies复制到文件中。
复制出来,内容结构大致如下：
代码语言：javascript复制curl 'https://domain-wss.cloud.tencent.com/domains/api/domain/certificate?domain=djangowang.vip&g_tk=402638928'

--compressed将以上内容复制到以下脚本中，并命名脚本文件名download_domainname.sh。
代码语言：javascript复制#!/bin/bash
# filename:download_domainname.sh
while read line
do
domainName=$line
curl -o $domainName.jpg 'https://domain-wss.cloud.tencent.com/domains/api/domain/certificate?domain='$domainName'&g_tk=402638928'

compressed
done < domainfile到腾讯云控制台，批量下载证书域名到本地（https://console.cloud.tencent.com/domain/all-domain）。
下载后用Excel打开复制第一列域名到domainfile文件中。
执行一下download_domainname.sh脚本，最终证书就会下载到当前目录中。
