我正在尝试使用python3来返回http://www.doi2bib.org/生成的bibtex引文。 url是可预测的,因此脚本可以在不必与网页交互的情况下计算出url。我尝试过使用selenium,bs4等,但无法获取文本框内的文字。
url = "http://www.doi2bib.org/#/doi/10.1007/s00425-007-0544-9"
import urllib.request
from bs4 import BeautifulSoup
text = BeautifulSoup(urllib.request.urlopen(url).read())
print(text)
有人能建议一种在python中将bibtex引用作为字符串(或其他)返回的方法吗?
答案 0 :(得分:9)
你在这里不需要BeautifulSoup
。有一个额外的XHR请求已发送到服务器以填写bibtex引文,例如使用requests
进行模拟:
import requests
bibtex_id = '10.1007/s00425-007-0544-9'
url = "http://www.doi2bib.org/#/doi/{id}".format(id=bibtex_id)
xhr_url = 'http://www.doi2bib.org/doi2bib'
with requests.Session() as session:
session.get(url)
response = session.get(xhr_url, params={'id': bibtex_id})
print(response.content)
打印:
@article{Burgert_2007,
doi = {10.1007/s00425-007-0544-9},
url = {http://dx.doi.org/10.1007/s00425-007-0544-9},
year = 2007,
month = {jun},
publisher = {Springer Science $\mathplus$ Business Media},
volume = {226},
number = {4},
pages = {981--987},
author = {Ingo Burgert and Michaela Eder and Notburga Gierlinger and Peter Fratzl},
title = {Tensile and compressive stresses in tracheids are induced by swelling based on geometrical constraints of the wood cell},
journal = {Planta}
}
您也可以使用selenium
解决此问题。这里的关键技巧是使用Explicit Wait等待引用to become visible:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Firefox()
driver.get('http://www.doi2bib.org/#/doi/10.1007/s00425-007-0544-9')
element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, '//pre[@ng-show="bib"]')))
print(element.text)
driver.close()
打印与上述解决方案相同。
