如何检测不是代理的ip

如何检测不是代理的ip

Busybox 环境下貌似不支持 grep -Po 这个命令，如何改呢

在脚本中有如下：
grep -Po '(?<="id":")[^"]*' | head -1 )

但是我当前环境是 BusyBox v1.24.1，貌似不支持这个 -- ‘P’的参数， 如何修改呢？

当前执行后报错：
No file, need IP
Updating zone_identifier & record_identifier
grep: invalid option -- 'P'
BusyBox v1.24.1 (2022-03-24 03:19:19 CST) multi-call binary.

Usage: grep [-HhnlLoqvsriwFE] [-m N] [-A/B/C N] PATTERN/-e PATTERN.../-f FILE [FILE]...

Search for PATTERN in FILEs (or stdin)

-H	Add 'filename:' prefix
-h	Do not add 'filename:' prefix
-n	Add 'line_no:' prefix
-l	Show only names of files that match
-L	Show only names of files that don't match
-c	Show only count of matching lines
-o	Show only the matching part of line
-q	Quiet. Return 0 if PATTERN is found, 1 otherwise
-v	Select non-matching lines
-s	Suppress open and read errors
-r	Recurse
-i	Ignore case
-w	Match whole words only
-x	Match whole lines only
-F	PATTERN is a literal (not regexp)
-E	PATTERN is an extended regexp
-m N	Match up to N times per file
-A N	Print N lines of trailing context
-B N	Print N lines of leading context
-C N	Same as '-A N -B N'
-e PTRN	Pattern to match
-f FILE	Read pattern from file

(23) Failed writing body

cloudflare v4's auth head changed

from: x-auth-key
to: Authorization: Bearer

运行无效果，但未报错

每次./脚本后
输出“no file.need ip” 和 “Updating zone_identifier & record_identifier”后无反应
cf面板未更新ip，且本地未生成两个存档数据的txt文件
我使用了全局api key 并且在两台机器上分别使用debian和centos做过测试，也用文件内使用方法在/usr目录下实验过
能想到的原因均测试过，实在没办法请教大佬们，希望有大佬解惑

Docker Image

Can you make this a Docker image?

运行报错了

应该是解析json出错了

第一次使用(未生成文件时)，API KEY错误情况下，运行不产生报错

首先感谢大大精简好用的代码，在config填写正确的情况下没有问题，可以正常使用。
出于好奇自己研究了下
在API错误情况下打印：
No file, need IP
Updating zone_identifier & record_identifier
测试了下
大概出现在这个位置

cloudflare-api-v4-ddns/cf-v4-ddns.sh

Line 123 in 1336b07

CFZONE_ID=$(curl -s -X GET "https://api.cloudflare.com/client/v4/zones?name=$CFZONE_NAME" -H "X-Auth-Email: $CFUSER" -H "X-Auth-Key: $CFKEY" -H "Content-Type: application/json" | grep -Po '(?<="id":")[^"]*' | head -1 )

因为API错误的原因导致文件直接退出没有继续执行后文的错误检测代码

修不来……我爬了

Updating DNS to error code: 1020

我是在crontab里做的定时任务
*/5 * * * * cf-v4-ddns.sh >> /home/latezly/cf-ddns.log 2>&1

刚开始启动的时候一直是正常的
过了一段时间就开始报这个错误

Updating DNS to error code: 1020
Something went wrong :(
Response: {"result":null,"success":false,"errors":[{"code":9005,"message":"Content for A record must be a valid IPv4 address."}],"messages":[]}

期间偶尔也有一段时间又恢复正常了

shell script enhancement

If record is not exist, It is better to add an echo message or use the add record api.
