我是wsj的付费会员,我想从linux终端登录我的wsj帐户,因此我可以编写代码以将一些文章用于我的NLP研究。我不会发布任何数据。
我的方法是基于Scrap articles form wsj by requests, CURL and BeautifulSoup的先前答案当时可以使用但现在不可用的代码的主要问题是,显然wsj采用了另一种OAuth 2.0方法。首先,我无法通过运行login_url获得连接。我有点觉得这是瓶颈。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领域。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'
它的确返回:“找到。重定向到/ login?state = XXXX ....”但不确定在此步骤后如何使用状态参数。

请求还需要一些其他参数。它需要state
和nonce
。同样,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https://accounts.wsj.com/login下脚本标签内的Base64编码JSON中>
您可以如下更新bash脚本。它使用curl,jq,sed和pup:
