I'm working on a bash script that requires capturing cookies from web requests.
What I'm Trying to Achieve
- Create a temporary file using
mktemp - Use curl to make a web request
- Capture all cookies set by the server in this temporary file
- Be able to read and use these cookies in subsequent requests
My Current Approach which is working
COOKIE_FILE=~/cookies.txt
curl https://example.com -c "$COOKIE_FILE" -b "$COOKIE_FILE"
Temporary file approach (fails)
COOKIE_FILE=$(mktemp)
curl https://example.com -c "$COOKIE_FILE" -b "$COOKIE_FILE"
and
COOKIE_FILE=$(tempfile --mode=666)
curl https://example.com -c "$COOKIE_FILE" -b "$COOKIE_FILE"
