如何在 Wget 中使用 Firefox cookie？

Question

wget --load-cookies将 cookie 作为“最初由 Netscape 的 cookies.txt 文件使用的格式的文本文件”加载。但是，Firefox 将其 cookie 保存在SQLite数据库中。

有没有办法从 Firefoxcookies.sqlite文件中提取“Netscape 的 cookies.txt 文件” ？

Answer 1

您可以使用 cookie 导出器扩展来导出可与 wget 一起使用的 cookie.txt 格式文件。

或者，您可以创建自己的。Cookie 可在 中查看Options / Privacy / remove individual cookies。你可以找到你想要的 cookie 并创建一个包含信息的 .txt 文件：

domain - The domain that created AND that can read the variable. 
flag - A TRUE/FALSE value indicating if all machines within a given domain can access the variable.  Say "true" 
path - The path within the domain that the variable is valid for.  Use / for any url
secure - A TRUE/FALSE value indicating if a secure connection with the domain is needed to access the variable. Use false to allow http://
expiration - The UNIX time that the variable will expire on.  Set something far in the future
name - The name of the variable. 
value - The value of the variable.

例如，一个人可能看起来像这样：

.domain.com TRUE  / FALSE 4102358400 SESSIONID dfjdfkjsjwere090fusfdkljf

如果您正在使用wget，那么您可能很熟悉命令行。在这种情况下，您可以使用一个简单的 shell 脚本来代替 Firefox 扩展：

extract_cookies.sh > mycookies.txt
wget --load-cookies mycookies.txt examplehost.com

您可以从https://gist.github.com/hackerb9/d382e09683a52dcac492ebcdaf1b79af下载extract_cookies.sh 脚本或剪切并粘贴以下内容：

#!/bin/sh -e
# extract_cookies.sh:
#
# Convert from Firefox's cookies.sqlite format to Netscape cookies,
# which can then be used by wget and curl. (Why don't wget and curl
# just use libsqlite if it's installed? Mysteries abound.)

# USAGE:
#
# $ extract_cookies.sh > /tmp/cookies.txt
# or
# $ extract_cookies.sh ~/.mozilla/firefox/*default*/cookies.sqlite > /tmp/cookies.txt

# USING WITH WGET:
# $ wget --load-cookies=/tmp/cookies.txt http://example.com

# USING WITH CURL:
# $ curl --cookie /tmp/cookies.txt http://example.com

# Note: If you do not specify an SQLite filename, this script will
# intelligently find it for you.
#
# A) Usually it will check all profiles under ~/.mozilla/firefox/ and
# use the cookies.sqlite that was updated most recently.
#
# B) If you've redirected stdin (with < or |) , then that will be used.
