如何使用 curl 将收到的 cookie 信息打印到标准输出？
According to the man pages if you use '-' as the file name for the -c --cookie-jar option it should print the cookie to stdout. The problem is I get an error:
根据手册页，如果您使用“-”作为 -c --cookie-jar 选项的文件名，它应该将 cookie 打印到标准输出。问题是我收到一个错误：
curl: option -: is unknown
an example of the command I am running:
我正在运行的命令示例：
curl -c --cookie-jar - 'http://google.com'

You get that error because you use in the wrong way that option. When you see in a man page an option like:
您会收到该错误，因为您以错误的方式使用该选项。当您在手册页中看到如下选项时：
-c, --cookie-jar <file name>
this mean that if you want to use that option, you must to use -cOR--cookie-jar, never both! These two are equivalent and, in fact, -cis the abbreviated form for --cookie-jar. There are many, many options in man pages which are designed in the same way.
这意味着如果你想使用那个选项，你必须使用-cOR--cookie-jar，永远不要同时使用！这两个是等价的，实际上-c是 的缩写形式--cookie-jar。手册页中有许多以相同方式设计的选项。
In your case:
在你的情况下：
curl -c - 'http://google.com'
--cookie-jaris given as argument for -coption, so, it's interpreted as a file name, not like an option (as you may think), and -remains alone which leads to error because curl, indeed, doesn't have such an option.
--cookie-jar作为-c选项的参数给出，因此，它被解释为一个文件名，而不是一个选项（如您所想），并且-仍然单独存在，这会导致错误，因为curl确实没有这样的选项。

You need to use two options to get only the cookie text on stdout:
您需要使用两个选项来仅获取 stdout 上的 cookie 文本：
--cookie-jar <file name>from the man page "If you set the file name to a single dash, '-', the cookies will be written to stdout"
--cookie-jar <file name>从手册页“如果您将文件名设置为单个破折号，'-'，cookies 将被写入标准输出”
--output <file>from the man page "Write output to instead of stdout". Set it to /dev/null to throw it away.
--output <file>来自手册页“将输出写入而不是标准输出”。将其设置为 /dev/null 以将其丢弃。
Also helpful is --silent
也有帮助的是 --silent
Putting it all together:
把它们放在一起：
curl --silent --output /dev/null --cookie-jar - 'http://www.google.com/'
curl --silent --output /dev/null --cookie-jar - 'http://www.google.com/'
Output:
输出：
# Netscape HTTP Cookie File
# https://curl.haxx.se/docs/http-cookies.html
# This file was generated by libcurl! Edit at your own risk.
#HttpOnly_.google.com TRUE / FALSE 1512524163 NID 105=DownH33BKZnCsWJeGvsIC5cKRi7CPT3K3QjfUB-4js5xGw6P_6svMqU1yKlKOEu4XwL_TdddZlcMITefFGOtCCyzJNhO_7E9UMNpbQHja40IAerYP5Bwj-FhY1m35mZdvkVSmrg1pZPvH96IkVVVVVVVV
My use case: Test that your website uses the HttpOnly cookie setting, per the OWASP recommendation:
我的用例：根据 OWASP 建议，测试您的网站是否使用 HttpOnly cookie 设置：
curl --silent --output /dev/null --cookie-jar - 'http://www.google.com/' | grep HttpOnly
回答by Matías Insaurralde
Remove the "-c"
删除“-c”
curl --cookie-jar - 'http://google.com'
Also you try verbose mode and see the cookie headers:
您还可以尝试详细模式并查看 cookie 标头：
curl -v 'http://google.com'

You can save the cookies received and send them back to the server using the following commands:
您可以使用以下命令保存收到的 cookie 并将它们发送回服务器：
1) To get/save the cookies to file "/tmp/cookies.txt":
1) 获取/保存 cookie 到文件“/tmp/cookies.txt”：
curl -c /tmp/cookies.txt http://the.site.with.cookies/
2) To send the cookies back to the server (again using file "/tmp/cookies.txt"):
2) 将 cookie 发送回服务器（再次使用文件“/tmp/cookies.txt”）：
curl -b /tmp/cookies.txt http://the.site.with.cookies/
I hope it was useful.
我希望它很有用。
