如何在Wget中使用Firefox cookie？

wget --load-cookies会将cookie加载为“文本文件，其格式最初是Netscape的cookies.txt文件使用的格式”。但是，Firefox将其cookie保留在SQLite数据库中。

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

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

或者，您可以创建自己的。Cookie在中可见Options / Privacy / remove individual cookies。您可以找到所需的Cookie并创建一个包含以下信息的.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.

因此，例如：

.domain.com TRUE  / FALSE 4102358400 SESSIONID dfjdfkjsjwere090fusfdkljf

如果您使用wget，则可能对命令行感到满意。在这种情况下，可以使用简单的Shell脚本代替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.


# HISTORY: I believe this is circa 2010 from:
# http://slacy.com/blog/2010/02/using-cookies-sqlite-in-wget-or-curl/
# However, that site is down now.

# Cleaned up by Hackerb9 (2017) to be more robust and require less typing.


cleanup() {
    rm -f $TMPFILE
    exit 0
}
trap cleanup  EXIT INT QUIT TERM


if [ "$#" -ge 1 ]; then
    SQLFILE="$1"
else
    if tty -s; then
    SQLFILE=$(ls -t ~/.mozilla/firefox/*/cookies.sqlite | head -1)
    else
    SQLFILE="-"     # Will use 'cat' below to read stdin
    fi
fi

if [ "$SQLFILE" != "-" -a ! -r "$SQLFILE" ]; then
    echo "Error. File $SQLFILE is not readable." >&2
    exit 1
fi

# We have to copy cookies.sqlite, because FireFox has a lock on it
TMPFILE=`mktemp /tmp/cookies.sqlite.XXXXXXXXXX`
cat "$SQLFILE" >> $TMPFILE


# This is the format of the sqlite database:
# CREATE TABLE moz_cookies (id INTEGER PRIMARY KEY, name TEXT, value TEXT, host TEXT, path TEXT,expiry INTEGER, lastAccessed INTEGER, isSecure INTEGER, isHttpOnly INTEGER);

echo "# Netscape HTTP Cookie File"
sqlite3 -separator $'\t' $TMPFILE <<- EOF
    .mode tabs
    .header off
    select host,
    case substr(host,1,1)='.' when 0 then 'FALSE' else 'TRUE' end,
    path,
    case isSecure when 0 then 'FALSE' else 'TRUE' end,
    expiry,
    name,
    value
    from moz_cookies;
EOF

cleanup

在大多数系统上，查找sql​​ite文件的方式不起作用。

如果因为有多个Firefox配置文件而拥有多个sqlite文件，该怎么办。

所以这是我的做法：

获取所有cookies.sqlite文件，按行号对它们进行排序，并假设行数最多的是您实际使用最多的行。然后返回该文件的路径。

因此，我将您的行更改为：

SQLFILE=$(find ~ -type f -name cookies.sqlite -exec wc -l {} \+ | sort -rn |grep -v total| head -1 |egrep -o "/.*")
