用cas使用bash進行身份驗證，curl命令行

我發現這個腳本用於使用cas進行身份驗證，從命令行使用curl和bash（請參閱下面的代碼）獲取受保護的URL。但是，我無法使腳本正常工作。我已驗證我能夠提取LoginTicket，JSESSION並提供正確的用戶名和密碼。然而，即使我已經證實我提供了所有正確的信息，cas服務器似乎也沒有反應。它只是一次又一次地返回登錄頁面而沒有任何錯誤消息。用cas使用bash進行身份驗證，curl命令行

這個腳本仍然是一個可行的方法嗎？或者我需要使用cas REST-API，如果我想使用命令行獲取有效的cas票，現在adays？

# Usage: cas-get.sh {url} {username} {password} # If you have any errors try removing the redirects to get more information 
# The service to be called, and a url-encoded version (the url encoding isn't perfect, if you're encoding complex stuff you may wish to replace with a different method) 
DEST="$1" 
ENCODED_DEST=`echo "$DEST" | perl -p -e 's/([^A-Za-z0-9])/sprintf("%%%02X", ord($1))/seg' | sed 's/%2E/./g' | sed 's/%0A//g'` 

#IP Addresses or hostnames are fine here 
CAS_HOSTNAME=team.eea.sk 

#Authentication details. This script only supports username/password login, but curl can handle certificate login if required 
USERNAME=$2 
PASSWORD=$3 

#Temporary files used by curl to store cookies and http headers 
COOKIE_JAR=.cookieJar 
HEADER_DUMP_DEST=.headers 
rm $COOKIE_JAR 
rm $HEADER_DUMP_DEST 

#The script itself is below 

#Visit CAS and get a login form. This includes a unique ID for the form, which we will store in CAS_ID and attach to our form submission. jsessionid cookie will be set here 
CAS_ID=`curl -s -k -c $COOKIE_JAR https://$CAS_HOSTNAME/cas/login?service=$ENCODED_DEST | grep name=.lt | sed 's/.*value..//' | sed 's/\".*//'` 

#Submit the login form, using the cookies saved in the cookie jar and the form submission ID just extracted. We keep the headers from this request as the return value should be a 302 including a "ticket" param which we'll need in the next request 
curl -s -k --data "username=$USERNAME&password=$PASSWORD&lt=$CAS_ID&_eventId=submit" -i -b $COOKIE_JAR -c $COOKIE_JAR https://$CAS_HOSTNAME/cas/login?service=$ENCODED_DEST -D $HEADER_DUMP_DEST -o /dev/null 

#Linux may not need this line but my response from the previous call has retrieving windows-style linebreaks in OSX 
#dos2unix $HEADER_DUMP_DEST > /dev/null 

#Visit the URL with the ticket param to finally set the casprivacy and, more importantly, MOD_AUTH_CAS cookie. Now we've got a MOD_AUTH_CAS cookie, anything we do in this session will pass straight through CAS 
CURL_DEST=`grep Location $HEADER_DUMP_DEST | sed 's/Location: //'` 
curl -s -k -b $COOKIE_JAR -c $COOKIE_JAR $CURL_DEST 

#If our destination is not a GET we'll need to do a GET to, say, the user dashboard here 

#Visit the place we actually wanted to go to 
curl -s -k -b $COOKIE_JAR "$DEST"
