Python dynamic DNSPod DNS Script

替换上你的 API Token,域名ID,记录ID等参数,就可以运行了。 会在后台一直运行,每隔30秒检查一遍IP,如果修改了就更新IP。

获取 API Token 的方式

获得 domain_id 可以用 curl

curl -k https://dnsapi.cn/Domain.List -d "login_token=TOKEN"`
#!/usr/bin/env python
#
# Converts any integer into a base [BASE] number. I have chosen 62
# as it is meant to represent the integers using all the alphanumeric
# characters, [no special characters] = {0..9}, {A..Z}, {a..z}
#
# I plan on using this to shorten the representation of possibly long ids,
# a la url shortenters

Turn any string into a valid filename in Python.
def format_filename(s):
"""Take a string and return a valid filename constructed from the string.
Uses a whitelist approach: any characters not present in valid_chars are
removed. Also spaces are replaced with underscores.
Note: this method may produce invalid filenames such as ``, `.` or `..`
When I use this method I prepend a date string like '2009_01_15_19_46_32_'
and append a file extension like '.txt', so I avoid the potential of using
an invalid filename.
