I. Hashlib module　　 Python's hashlib provides a common digest algorithm, such as MD5,SHA1 and so on.Abstract the algorithm is also called hash algorithm and hashing algorithm. It uses a function to convert any length of data into a fixed length data string (usually represented by a 16-binary string).　　abstract the algorithm is to calculate the fixed-length summary digest by the Digest function f () to the data of arbitrary length, in order to find out

In Nodejs, modules can be divided into core modules and file modules. The core module is compiled into binary code, which can be referenced only with require notation, such as (Require (' net ')). File module refers to a JS file, a JSON file, or a. node file. The path to add the file after referencing the file module:/.../.../xxx.js represents the absolute path

follows:可见在logging.basicConfig()函数中可通过具体参数来更改logging模块默认行为，可用参数有filename：用指定的文件名创建FiledHandler（后边会具体讲解handler的概念），这样日志会被存储在指定的文件中。filemode：文件打开方式，在指定了filename时使用这个参数，默认值为“a”还可指定为“w”。format：指定handler使用的日志显示格式。 datefmt：指定日期时间格式。 level：设置rootlogger（后边会讲解具体概念）的日志级别 stream：用指定的stream创建StreamHandler。可以指定输出到sys.stderr,sys.stdout或者文件(f=open(‘test.log‘,‘w‘))，默认为sys.stderr。若同时列出了filename和stream两个参数，则stream参数会被忽略。format参数中可能用到的格式化串：%(name)s Logger的名字%(levelno)s 数字形式的日志级别%(levelname)s 文本形式的日志级别%(pathname)s
