在 Python 中使用 doi 自动下载

如何解决在 Python 中使用 doi 自动下载

我在一个 csv 文件中有大约 1000 个与相关 doi 相关的文章链接，我需要下载这些论文。

我尝试了以下方法：

List_dois = [""] #here I have inserted the list of 1000 doi

out = 'out_folder'
logging.basicConfig(filename='myapp.log',level=logging.INFO)
for doi in List_dois:
    try:
        SciHub(doi,out).download(choose_scihub_url_index=3)
        time.sleep(10)
    except:
        logging.info("Error!",sys.exc_info()[0],doi)

但是在大​​约 10 次下载后，它会生成以下错误：

Traceback (most recent call last):
  File "/home/username/PycharmProjects/pythonProject3/main.py",line 65,in <module>
    sci = SciHub(doi,out).download(choose_scihub_url_index=3)
  File "/home/username/PycharmProjects/pythonProject3/venv/lib/python3.8/site-packages/scidownl/scihub.py",line 90,in download
    self.download_pdf(pdf)
  File "/home/username/PycharmProjects/pythonProject3/venv/lib/python3.8/site-packages/scidownl/scihub.py",line 147,in download_pdf
    if self.is_captcha_page(res):
  File "/home/usernamePycharmProjects/pythonProject3/venv/lib/python3.8/site-packages/scidownl/scihub.py",line 184,in is_captcha_page
    return 'must-revalidate' in res.headers['Cache-Control']
  File "/home/username/PycharmProjects/pythonProject3/venv/lib/python3.8/site-packages/requests/structures.py",line 54,in getitem
    return self._store[key.lower()][1]
KeyError: 'cache-control'

我该如何解决这个问题？ 睡眠时间不要增加太多，不然操作真的太长了...
