开源的Cloudflare优选IP+DnsPod的解析自动切换
Cloudflare优选IP 每隔15分钟更新(IPv6+IPv4)
项目地址：https://github.com/uxiaohan/CloudflareIP-dnspod-ddns
实现逻辑及局部代码
获取优选IP
const res = await fetch("https://api.vvhan.com/tool/cf_ip");
const data = await res.json();
// 数据格式
// {
// "success": true,
// "data": {
// "v4": {
// "CM": [],
// "CU": [],
// "CT": []
// },
// "v6": {
// "CM": [],
// "CU": [],
// "CT": []
// }
// }
// }
取优选IP中的最优选 (延迟比较)
// 取最优选IP IPv4
const CM_IP_V4 = data.v4.CM.reduce((minItem, currentItem) => {
return currentItem.latency < minItem.latency ? currentItem : minItem;
}, data.v4.CM[0]);
const CU_IP_V4 = data.v4.CU.reduce((minItem, currentItem) => {
return currentItem.latency < minItem.latency ? currentItem : minItem;
}, data.v4.CU[0]);
const CT_IP_V4 = data.v4.CT.reduce((minItem, currentItem) => {
return currentItem.latency < minItem.latency ? currentItem : minItem;
}, data.v4.CT[0]);
const DNS_DATA_V4 = { 移动: CM_IP_V4.ip, 联通: CM_IP_V4.ip, 电信: CU_IP_V4.ip, 默认: CT_IP_V4.ip };
// 取最优选IP IPv6
const CM_IP_V6 = data.v6.CM.reduce((minItem, currentItem) => {
return currentItem.latency < minItem.latency ? currentItem : minItem;
}, data.v6.CM[0]);
const CU_IP_V6 = data.v6.CU.reduce((minItem, currentItem) => {
return currentItem.latency < minItem.latency ? currentItem : minItem;
}, data.v6.CU[0]);
const CT_IP_V6 = data.v6.CT.reduce((minItem, currentItem) => {
return currentItem.latency < minItem.latency ? currentItem : minItem;
}, data.v6.CT[0]);
const DNS_DATA_V6 = { 移动: CM_IP_V6.ip, 联通: CM_IP_V6.ip, 电信: CU_IP_V6.ip, 默认: CT_IP_V6.ip };
循环替换优选IP
DnsPodDomainList.forEach(async i => {
try {
const res = await client.ModifyRecord({ Domain, RecordType: i.Type, RecordLine: "", RecordLineId: i.LineId, Value: i.Type == "A" ? DNS_DATA_V4[i.Line] : DNS_DATA_V6[i.Line], RecordId: i.RecordId, SubDomain });
console.log(res);
} catch (error) {
console.log(error);
}
});
附注：Node18+，不然不支持fetch
你也可以更改为：axios
CD 进入目录执行命令pnpm add axios
同时修改文件：controller.js第1-15行代码如下：
const moment = require("moment");
const axios = require("axios");
// 配置
const { secretId, secretKey, Domain, SubDomain } = require("./config");
const tencentcloud = require("tencentcloud-sdk-nodejs-dnspod");
// 更新 Cloudflare 优选IP开始-----------------------------------------------------------------------------------------------------
const updateCloudflareIp = async () => {
const res = await axios.get("https://api.vvhan.com/tool/cf_ip");
const data = res.data;
if (!data.success) {
console.log("\x1b[91m%s\x1b[0m", "更新 Cloudflare 优选IP失败");
return "更新 Cloudflare 优选IP失败";
}
return await updateTencentDns(data.data);
};
// 更新 Cloudflare 优选IP结束----------------------------------------------------站长科技导航网-------------------------------------------------
