CURL 访问需要从不同页面登录的页面 [英] CURL to access a page that requires a login from a different page

问题描述

我有 2 个页面:xyz.com/a 和 xyz.com/b.当且仅当我先登录 xyz.com/a 时，我才能访问 xyz.com/b.如果访问 xyz.com/b 而不通过另一个，我只会通过浏览器拒绝访问(没有重定向到登录).一旦我登录 xyz.com/a，我就可以访问另一个.

I have 2 pages: xyz.com/a and xyz.com/b. I can only access xyz.com/b if and only if I login to xyz.com/a first. If accessing xyz.com/b without going through the other, I simply get access denied (no redirect to login) via the browser. Once I login at xyz.com/a, I can access the other.

我的问题是使用 curl 命令执行此操作.我可以使用 curl 成功登录到 xyz.com/a，但随后尝试 xyx.com/b 并且我的访问被拒绝.

My problem is doing this using the curl command. I can login successfully to xyz.com/a using curl, but then try xyx.com/b and I get access denied.

我使用以下内容:

curl --user user:pass https://xyz.com/a  #works ok
curl https://xyz.com/b #doesn't work

我尝试将第二行与 & 一起使用没有用户/密码部分，仍然不起作用.两个页面都使用相同的 CA，所以这不是问题.有什么建议?谢谢

I've tried using the second line with & without the user/password part and still doesn't work. Both pages uses the same CA, so that's not a problem. Any suggestions? Thanks

推荐答案

该网站可能使用 cookies 来存储您的会话信息.当你跑

The web site likely uses cookies to store your session information. When you run

curl --user user:pass https://xyz.com/a  #works ok
curl https://xyz.com/b #doesn't work

curl 在两个单独的会话中运行两次.因此，当第二个命令运行时，第一个命令设置的 cookie 不可用；这就像您在一个浏览器会话中登录页面 a，并尝试在另一个浏览器会话中访问页面 b.

curl is run twice, in two separate sessions. Thus when the second command runs, the cookies set by the 1st command are not available; it's just as if you logged in to page a in one browser session, and tried to access page b in a different one.

你需要做的是保存第一个命令创建的cookies:

What you need to do is save the cookies created by the first command:

curl --user user:pass --cookie-jar ./somefile https://xyz.com/a

然后在运行第二个时读回它们:

and then read them back in when running the second:

curl --cookie ./somefile https://xyz.com/b

或者，您可以尝试在同一个命令中下载这两个文件，我认为这将使用相同的 cookie.

Alternatively you can try downloading both files in the same command, which I think will use the same cookies.
