bash脚本将ssh登录发送到最重要的地方的问题[重复]

Question

#!/bin/bash

#Variable
USER="User:          $PAM_USER"
REMOTE="Remote host: $PAM_RHOST"
SERVICE="Service:    $PAM_SERVICE"
TTY="TTY:            $PAM_TTY"
DATE="Date:          `date`"
SERVER="Server:      `uname -a`"
LOGINMESSAGE="$PAM_SERVICE login on `hostname -s` for account    $PAM_USER"

if [ "$PAM_TYPE" = "open_session" ]
then
# dont function
curl -i -X POST -d 'payload={"text": "${PAM_RHOST}" ,    "username":"ssh", "channel":"monitoring"}' \  https://domain/hooks/xxx
# function
curl -i -X POST -d 'payload={"text": "Hello, world!", "username":"sshbot", "channel":"monitoring"}' \  https://domain/hooks/xxx
fi
exit 0

我期望在成功登录时传输变量。

Answer 1

'payload={“text”：“${PAM_RHOST}”...“用单引号包装。它不允许展开变量${PAM_RHOST}。

如果需要扩展，请更改

curl -i -X POST -d 'payload={"text": "${PAM_RHOST}" ,    "username":"ssh", "channel":"monitoring"}' \  https://domain/hooks/xxx

成，

curl -i -X POST -d 'payload={"text": '"${PAM_RHOST}"' ,    "username":"ssh", "channel":"monitoring"}' \  https://domain/hooks/xxx
