我是wsj的付费会员，我想从linux终端登录到我的wsj帐户，这样我就可以编写代码来抓取一些文章来进行NLP研究。我不会公布任何数据。
我的方法是基于之前根据请求、CURL和BeautifulSoup从wsj的Scrape文章中得到的答案当时有效但现在不起作用的代码的主要问题是，显然wsj采用了不同的OAuth 2.0方法。首先，我无法再通过运行login_url来获得连接。我觉得这是个瓶颈。这是下一步的必填字段。
我注意到的另一件事是使用了状态参数。我不知道如何使用这个字段。运行后
curl -s 'https://sso.accounts.dowjones.com/authorize?scope=openid+idp_id+roles+email+given_name+family_name+djid+djUsername+djStatus+trackid+tags+prts&client_id=XXXXXXX&response_type=code&redirect_uri=https%3A%2F%2Faccounts.wsj.com%2Fauth%2Fsso%2Flogin&state=https://www.wsj.com&username=XXXXXX&password=XXXXXX'
它确实返回："建立是否重定向到/login？状态=XXXX"但不确定在该步骤之后如何使用状态参数。

/usernamepassword/login请求还需要一些参数。它需要state和nonce。此外，connection字段似乎不再出现在Location标头中，而是硬编码在js文件中。
凭据详细信息嵌入在下面的脚本标记内的Base64编码JSON中https://accounts.wsj.com/login
您可以按如下方式更新bash脚本。它使用curl，jq，sed和amp；小狗：
#/bin/bash
username="your_email@gmail.com"
password="your_password"
base_url="https://accounts.wsj.com"
rm -f cookies.txt
login_page=$(curl -s -L -c cookies.txt "$base_url/login")

但是这个bash脚本维护起来很痛苦，我建议使用这样的python脚本：
import requests

import re
import base64
import json
username="your_email@gmail.com"
password="your_password"
base_url="https://accounts.wsj.com"
session = requests.Session()
r = session.get("{}/login".format(base_url))
soup = BeautifulSoup(r.text, "html.parser")
jscript = [
t.get("src")
for t in soup.find_all("script")
if t.get("src") is not None and "app-min" in t.get("src")
][0]
credentials_search = re.search("Base64.decode('(.*)'", r.text, re.IGNORECASE)
base64_decoded = base64.b64decode(credentials_search.group(1))
credentials = json.loads(base64_decoded)
print("client_id : {}".format(credentials["clientID"]))
print("state : {}".format(credentials["internalOptions"]["state"]))
print("nonce : {}".format(credentials["internalOptions"]["nonce"]))
print("scope : {}".format(credentials["internalOptions"]["scope"]))
r = session.get("{}{}".format(base_url, jscript))
connection_search = re.search('connection:s*"(w+)"', r.text, re.IGNORECASE)
connection = connection_search.group(1)
r = session.post(
'https://sso.accounts.dowjones.com/usernamepassword/login',
data = {
"username": username,

})
soup = BeautifulSoup(r.text, "html.parser")
login_result = dict([

for t in soup.find_all('input')
if t.get("name") is not None
])
r = session.post(
'https://sso.accounts.dowjones.com/login/callback',
data = login_result)
#check connected user
r = session.get("https://www.wsj.com/articles/singapore-prime-minister-lee-rejects-claims-he-misused-state-powers-in-family-feud-1499094761?tesla=y")
username_search = re.search('"firstName":s*"(w+)",', r.text, re.IGNORECASE)
