从多个联机图书源查找图书下载URL
pybooks的Python项目详细描述
安装
$ pip install pybooks
用法
简单用法
from pybooks.pbook import Pbooks
pbook = Pbooks( author='jerome',
title='elements of statistic',
weights=(9, 1))
pbook.main()
参数weights用于计算找到的所有项和最终选择的url的准确性。例如，weights的(9, 1)将比title对作者准确性更重要，因此结果更有可能使author的名称与输入更相似。默认权重为(1, 1)
可选参数有show_result: Print the result at the end or not、threshold: Only print result with accuracy higher than threshold和log: Show process while running or not等。在代码文档中可以找到更多参数。
可以通过编辑文件PyBoox/SuthCE.jSON修改和添加其他源，并按照文件中的现有格式。
sources.json格式，规则
示例： Library Genesis with elements of statistics as search term
我们在url中只需要以下组件：request: ?req=...、delimiter: + (elements+of+statistics)、pagination: page=...和term_concatenation: & (req=...&page=...)
INSIDE SOURCES.JSON
URL: main url without search terms
URL_RULES: dictionary contains keys and values as search rules.
HTML_RULES: Contains nested dictionary represent necessary components to conduct searches such as tags, attributes for titles, authors, rows and page body
.POSITION: The position of the that element in the row if there are other similar elements with similar tag and attributes, leave as null if it is unique
.TAG: The tag of the desired element
.ATTRIBUTE: Attributes of the tag, for exanple: {"class": "id", "...": "..", ...}. Leave the value of a key as true if an attribute has no value
命令行用法
可以直接从命令行使用包
示例：搜索一本书名为“统计学习要素”和作者为“Jerome Friedman”的书
您可以将pbook.exe添加到环境变量中，并通过此命令从命令行使用它，%PATH%作为指向pybooks目录（文件夹）的路径，通常可以在\Python{version}\Lib\pybooks中找到。
setx PATH "%PATH%pbook -a "jerome friedman" -t "elements of statistical learning"
