这里先说一下,CloudFlare是一家DNS供应商(我是这么理解的),他有提供很多服务(HTTPS/CDN等等),具体的大家可以自己去官网看一下:www.cloudflare.com

CloudFlare建议使用linux的curl命令使用开发的API

因shell不能很好的处理CloudFlare返回的json数据,所以在使用shell的基础上,增加了python脚本

本文件一共有四个脚本文件配合使用:

  1. domians.txt :用来存放需要添加的域名
  2. env.env :存放各种变量
  3. filter_zone_id.py :用于将CloudFlare返回的数据过滤(过滤出域名及其区域ID)
  4. filter_dns_id.py :用于将CloudFlare返回的数据过滤(过滤出解析记录及其区域ID)
  5. main.sh :存放linux命令,执行时也是执行这一个脚本即可

一、 domain.txt就不用介绍了,就是把顶级域名写到里面,一行一个
二、 env.env

  #!/bin/bash

#通用变量
#当前目录
PWD=$(pwd)

PYTHON=$(which python)

ECHO=$(which echo)

#这里DNS指的是解析记录
#账号
CF_API_EMAIL=CloudFlare的登录账号
#秘钥
CF_API_KEY=在用户信息里面查看“Global KEY”
#组织名
organization_name="组织名"
#组织ID
organization_id="组织ID"
#设置CNAME 和 IP
CONTENT_CNAME=域名需要解析的别名“CNAME”
CONTENT_IP=域名需要解析的别名IP
#get_zone_id.cf     -- 存放新增域名时Cloudflare返回的JSON 数据
#get_dns_id.cf      -- 存放获取DNS_ID时Cloudflare返回的JSON 数据
#filter_zone_id.py  -- 用于从 "get_zone_id.cf" 中过滤出域名及其相对应的区域ID并写入文件 "zone_id.cf"
#filter_dns_id.py   -- 用于从 "get_dns_id.cf" 中过滤出DNS_ID及其DNS_NAME并写入文件 "dns_id.cf"

二、main.sh

#!/bin/bash
source ./env.env

#新增域名
for domain in $(cat $PWD/domains.txt)
do
    curl -X POST -H "X-Auth-Key: ${CF_API_KEY}" \
    -H "X-Auth-Email: ${CF_API_EMAIL}" \
    -H "Content-Type: application/json" "https://api.cloudflare.com/client/v4/zones" \
     --data '{"name":"'"${domain}"'","jump_start":true,"organization":{"name":"'"${organization_name}"'","id":"'"${organization_id}"'"}}' >> $PWD/get_zone_id.cf
    ${ECHO} -e "\n" >> $PWD/get_zone_id.cf
done

#执行python脚本,过滤出域名的区域ID
$PYTHON $PWD/filter_zone_id.py

#获取DNS ID列表
while read line
do
    ZONE_NAME=$(${ECHO} "$line" | awk '{print $1}')
    ZONE_ID=$(${ECHO} "$line" | awk '{print $2}')
    curl -X GET "https://api.cloudflare.com/client/v4/zones/${ZONE_ID}/dns_records" \
         -H "X-Auth-Email: ${CF_API_EMAIL}" -H "X-Auth-Key: ${CF_API_KEY}" \
         -H "Content-Type: application/json" >> $PWD/get_dns_id.cf
    ${ECHO} -e "\n" >> $PWD/get_dns_id.cf
done < $PWD/zone_id.cf

#执行python脚本,过滤出DNS_ID
$PYTHON $PWD/filter_dns_id.py

#删除DNS记录
#删除DNS记录还需要指定区域ID,每个域名的区域DI不同,所以进行一个判断,判断DNS_NAME是否模糊匹配之前取到的ZONE_NAME
#如果匹配则使用这个ZONE_ID
while read zone
do
    ZONE_NAME=$(${ECHO} "$zone" | awk '{print $1}')
    ZONE_ID=$(${ECHO} "$zone" | awk '{print $2}')
    while read dns
    do
        DNS_NAME=$(${ECHO} "$dns" | awk '{ print $1 }')
        DNS_ID=$(${ECHO} "$dns" | awk '{ print $2 }')
        if [[ "*$DNS_NAME" =~ "$ZONE_NAME" ]]
        then
            curl -X DELETE "https://api.cloudflare.com/client/v4/zones/${ZONE_ID}/dns_records/${DNS_ID}" \
                 -H "X-Auth-Email:${CF_API_EMAIL}" \
                 -H "X-Auth-Key:${CF_API_KEY}" \
                 -H "Content-Type:application/json"
        fi
    done < $PWD/dns_id.cf
done < $PWD/zone_id.cf

#增加DNS记录
#TTL=1 为自动
#proxied=true 使用CF的CDN,等于false是不使用
#data传入变量格式: "'"$EVN"'"
#设置变量

while read line
do
    ZONE_NAME=$(${ECHO} "$line" | awk '{print $1}')
    ZONE_ID=$(${ECHO} "$line" | awk '{print $2}') 
    curl -X POST "https://api.cloudflare.com/client/v4/zones/${ZONE_ID}/dns_records" \
         -H "X-Auth-Email:${CF_API_EMAIL}" \
         -H "X-Auth-Key:${CF_API_KEY}" \
         -H "Content-Type:application/json" \
         --data '{"type":"A","name":"@","content":"'"${CONTENT_IP}"'","ttl":1,"priority":10,"proxied":true}'

    curl -X POST "https://api.cloudflare.com/client/v4/zones/${ZONE_ID}/dns_records" \
         -H "X-Auth-Email:${CF_API_EMAIL}" \
         -H "X-Auth-Key:${CF_API_KEY}" \
         -H "Content-Type:application/json" \
         --data '{"type":"CNAME","name":"www","content":"'"${CONTENT_CNAME}"'","ttl":1,"priority":10,"proxied":false}'

    curl -X POST "https://api.cloudflare.com/client/v4/zones/${ZONE_ID}/dns_records" \
         -H "X-Auth-Email:${CF_API_EMAIL}" \
         -H "X-Auth-Key:${CF_API_KEY}" \
         -H "Content-Type:application/json" \
         --data '{"type":"CNAME","name":"m","content":"'"${CONTENT_CNAME}"'","ttl":1,"priority":10,"proxied":false}'
done < $PWD/zone_id.cf

三、filter_zone_id.py

#!/usr/bin/env python
#*- coding:utf-8 -*

#打开文件获取添加域名成功后返回的数据,然后获取到域名的区域ID
#通过区域ID获取DNS列表

import json
import os
import traceback

#traceback 完整输出报错信息
#str(e) 只给出异常信息,不包括异常信息的类型,如1/0的异常信息
#repr(e) 给出较全的异常信息,包括异常信息的类型,如1/0的异常信息

PWD = os.getcwd()

PWD_GET = PWD+'/get_zone_id.cf'
PWD_ZONE = PWD+'/zone_id.cf'
ERROR_FILE = PWD+'/zone_error.log'

#读取添加域名时返回的字符串,并且循环写入字典,以便于过滤出域名的区域ID
with open (PWD_GET,'r') as file:
    i = 0
    j = 0
    dict = {}
    list = []
    for line in file:
        if line.strip  == " " or line == "\n" or line == " \n":
            continue
        try:
            dict[i]=json.loads(line)
            i+=1
        except Exception as e:
            j+=1
            with open (ERROR_FILE,'a+') as file:
                title = "----------\t\t第%d条报错信息\t\t---------"%(j) + "\n"
                #info = "报错信息:" + traceback.format_exc() + "\n"
                info = "报错信息:" + repr(e) + "\n"
                mation = "报错行:" + line + "\n"
                file.writelines(title)
                file.writelines(info)
                file.writelines(mation)
            continue

#获取所有的key,然后进行循环遍历,获取每个域名的区域ID
keys_list = dict.keys()

for key in keys_list:
    ID=dict[key]['result']['id']
    NAME=dict[key]['result']['name']
    with open (PWD_ZONE,'a+') as file:
        line = NAME + " " + ID + "\n"
        file.writelines(line)

四、filter_dns_id.py

#!/usr/bin/env python
#*- coding:utf-8 -*

#打开文件读取cloudflare返回的DNS ID

import json
import os

PWD = os.getcwd()

PWD_GET = PWD+'/get_dns_id.cf'
PWD_DNS = PWD+'/dns_id.cf'

#读取获取DNS ID时返回的字符串,并且循环写入字典,以便于过滤出DNS ID
with open (PWD_GET,'r') as file:
    i = 0
    dict = {}
    for line in file:
        if line.strip  == " " or line == "\n" or line == " \n":
            continue
        dict[i]=json.loads(line)
        i+=1

key_list = dict.keys()

for key in key_list:
    list =  dict[key]['result']

    #一个域名可能有多个DNS记录,cloudflare返回的是一个列表,列表中是一个一个的字典,
    #一个key-values代表一个DNS记录,所以这里需要遍历列表中的字典
    #通过取列表的索引值,循环每一个位置的字典
    for i in list:
        with open (PWD_DNS,'a+') as file:
            line = i['name'] + " " + i['id'] + "\n"
            file.writelines(line)
