A small paper crawler
Project description
PaperCrawlerUtil
一套用来爬论文的工具,a collection of utils to get paper This project is an util package to create a crawler. It contains many tools which can finish part function. There is an example:
from PaperCrawlerUtil.util import *
basic_config(style="print")
for times in ["2019", "2020", "2021"]:
html = random_proxy_header_access("https://openaccess.thecvf.com/CVPR{}".format(times), random_proxy=False)
attr_list = get_attribute_of_html(html, {'href': "in", 'CVPR': "in", "py": "in", "day": "in"})
for ele in attr_list:
path = ele.split("<a href=\"")[1].split("\">")[0]
path = "https://openaccess.thecvf.com/" + path
html = random_proxy_header_access(path, random_proxy=False)
attr_list = get_attribute_of_html(html,
{'href': "in", 'CVPR': "in", "content": "in", "papers": "in"})
for eles in attr_list:
pdf_path = eles.split("<a href=\"")[1].split("\">")[0]
work_path = local_path_generate("cvpr{}".format(times))
retrieve_file("https://openaccess.thecvf.com/" + pdf_path, work_path)
本模块使用自己搭建的一个代理池,代码来自https://github.com/Germey/ProxyPool.git
也可以自己在本地搭建这样的代理服务器,然后使用如下代码更换代理池
basic_config(proxy_pool_url="http://localhost:xxxx")
同时可以替换,其他的一些配置,如下所示,其中日志的等级只能配置一次,之后不会再生效
basic_config(log_file_name="1.log",
log_level=logging.WARNING,
proxy_pool_url="http://xxx",
logs_style=LOG_STYLE_LOG)
如下所示,可以抽取路径上的PDF中的信息,其中路径可以是PDF也可以是文件路径,会自动判断
如果是文件夹,则会遍历所有文件,然后返回总的字符串,可以自选分割符的形式
同时信息的提取是通过两个标记实现的,即通过开始和结束标记截取字段
title_and_abstract = get_para_from_pdf(path="E:\\git-code\\paper-crawler\\CVPR\\CVPR_2021\\3\\3", ranges=(0, 2))
write_file(path=local_path_generate("E:\\git-code\\paper-crawler\\CVPR\\CVPR_2021\\3\\3", "title_and_abstract.txt"),
mode="w+", string=title_and_abstract)
也可以直接安装本包
pip install PaperCrawlerUtil
