我一直在尝试从this site中提取DNA序列但我似乎无法访问数据。我的代码如下所示。如果有任何帮助，我也在关注 this tutorial关于数据抓取和我的代码的开头应该看起来与他们的相似。
from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as bslol
# URl to web scrape from
page_url = 'https://www.ncbi.nlm.nih.gov/nuccore/MT755607.1?report=fasta'
# opens the connection and downloads html page from url
uClient = uReq(page_url)
# parses html into a soup data structure to traverse html
# as if it were a json data type.
page_soup = bslol(uClient.read(), "html.parser")
uClient.close()
为了获取文本，我首先尝试使用 print(page_soup.select('pre'))，它返回空括号。
然后我尝试执行 page_soup.find('div', {'class':'seq gbff'}).text 以及 page_soup.find('div', { 'class':'seq gbff'}).content 但无济于事。我还尝试使用 .findAll 来查看是否有任何更改，但这使我距离解决方案更近了一步。
如果有人能帮我解决这个问题，我将不胜感激。
最佳答案
当您分析网站时，网站会进行 ajax 调用来加载 DNA 序列。
import requests
res = requests.get('https://www.ncbi.nlm.nih.gov/sviewer/viewer.fcgi?id=1877761002&db=nuccore&report=fasta&extrafeat=null&conwithfeat=on&hide-cdd=on&retmode=html&withmarkup=on&tool=portal&log$=seqview&maxdownloadsize=1000000')
dna_sequence = res.text.strip()
print(dna_sequence)
输出:
>MT755607.1 Homo sapiens haplogroup A2-T16189C mitochondrion, complete genome
