使用Base32对字节串s进行编码。 base64.b32decode(s, casefold=False, map01=None) 对Base32编码的字节串进行解码,可选参数casefold用来标记是否接收小写字母作为输入。RFC3548允许数字0到字母O的映射,以及数字1到字母I或L的映射。当可选参数map01不是None时用来指定数字1映射为什么字母(此时数字0总是会被映射为字...

(often referred to as adata model) is implemented as a Python class and is used to map to a single database table. Once you’ve created your data models, you can use Django’s database-abstraction API to access and manipulate data in the mapped database tables in a pythonic way. This...
InFigure 1, you saw how an area of interest can be marked on a map. But how can you transfer this information to the database? To be more specific, how can the area enclosed by a polygon on a map be represented as a row in a database table, so you can use SQL to check wheth...
用python操作hbase时需要用到happybase库 python+happybase 1.pip install happybase 直接安装即可 2.测试安装 python -c ‘import happybase’,不报错就是正常的或直接导入happybase包不报错 3.安装thrift,thrift为一个语言编译器,在python去操作hbase是需要将语言重新编译为hbase底层支持的c++,具体可看https://www....
首先需要知道,图片转换成base64并不是加解密,而是编解码,主要的作用不在于安全性,而在于让内容能在各个网关间无错的传输,这才是Base64编码的核心作用。 1 base64编码原理 Base64编码是基于64个字符A-Z,a-z,0-9,+,/的编码方式,因为2的6次方正好为64,所以用6位就可以表示出这64个字符了。一个字节是8位,...
