所以有这个开源应用程序将引用字符串解析为 BibTex 格式，我正在尝试使用 Python Requests 将其功能集成到我的项目中。
我知道该表单具有 CSRF 保护，因此我确保将令牌作为 POST 请求的一部分包含在内，但这并没有成功，返回 404 错误：
from requests import Session
from lxml import html
citations = ["107 F. Scarpa, S. Blain, T. Lew, D. Perrott, M. Ruzzene and J. Yates, Elastic buckling of hexagonal chiral cell honeycombs, Composites, Part A, 2007, 38(2), 280–289"]
s = Session()
url = 'https://anystyle.io/'
page = s.get(url)
tree = html.fromstring(page.content)
csrf_token = tree.xpath("/html/head/meta[4]/@content")[0]
response = s.post(
headers = {
'Origin': url,
'Referer': url,
'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0',
'Accept': 'application/json, text/plain, */*',
'Accept-Language': 'en-US,en;q=0.5',
'Content-Type': 'application/json;charset=utf-8',
'Connection': 'keep-alive',
'X-CSRF-TOKEN': csrf_token
},
url = url,
params = (
('format', 'json'),
),
json = {
'input': citations
},
cookies = {
'_any_style_session': s.cookies.get('_any_style_session')
}
)
response.json()
我想知道的是，上面的代码是否正确解决了 CSRF 问题以返回成功的请求，或者应用程序的设计方式是否可以防止自动请求。
添加/parse到 POST 网址：
from requests import Session
from lxml import html
citations = ["107 F. Scarpa, S. Blain, T. Lew, D. Perrott, M. Ruzzene and J. Yates, Elastic buckling of hexagonal chiral cell honeycombs, Composites, Part A, 2007, 38(2), 280–289"]
s = Session()
url = 'https://anystyle.io'
page = s.get(url)
tree = html.fromstring(page.content)
csrf_token = tree.xpath("/html/head/meta[4]/@content")[0]
response = s.post(
headers = {
'X-CSRF-TOKEN': csrf_token # <-- only this header is needed
},
url = url + '/parse', # <-- add '/parse' here!
params = (
('format', 'json'),
),
json = {
'input': citations
},
# cookies= are not needed:
)
print( response.json() )
