我正在尝试使用以下代码登录网站并获取内容，但是当我运行代码时，输​​出不可读，并且代码也没有给出任何错误/异常。代码是否正常工作并登录网站但数据已加密，因此这就是它在控制台中显示的内容，或者代码是否存在问题

加密文本比我展示的要多得多，并且这在控制台中一次又一次地重复

Answer 1

我认为加密后的内容就是cookie的内容。另外，您说您没有收到任何错误，那么您如何解释输出中提供的警告:

WARNING: Cookie rejected: "BALANCEID=mycluster2.node3". Illegal path attribute "/resources"

检查您是否正确使用 cookie
