How to pass Named Parameter in Shell Script

Question

Below is the shell script using getopts

#!/bin/bash

while getopts "USER:PWD:JOBID:PROJECTID:" flag
do
         case "${flag}" in
                USER) TEST_USER=${OPTARG};;
                PWD) TEST_PWD=${OPTARG};;
                JOBID) TEST_JOBID=${OPTARG};;
                PROJECTID) TEST_PROJECTID=${OPTARG};;
         esac
       
done
echo "USER: $TEST_USER";
echo "PWD: $TEST_PWD";
echo "JOBID: $TEST_JOBID";                  
echo "PROJECTID: $TEST_PROJECTID"; 

Continue of script i have not put here and if above commands work fine then my issue solve 

And Here what im running output in terminal, Which one is a correct way to get output command

./getopts.sh -USER=devops@gmail.com -PWD=xxxxxx -JOBID=8a809e2496 -PROJECTID=80e2ea54b231f
OR
./getopts.sh USER=devops@gmail.com PWD=xxxxxx JOBID=8a809e2496 PROJECTID=80e2ea54b231f

After running above command im getting empty response or string USER: PWD: JOBID: PROJECTID:

You may want to read the getopts manual page

    while getopts "U:P:J:I:" flag
    do
             case "${flag}" in
                    U) TEST_USER=${OPTARG};;
                    P) TEST_PWD=${OPTARG};;
                    J) TEST_JOBID=${OPTARG};;
                    I) TEST_PROJECTID=${OPTARG};;
             esac
    done
    echo "USER: $TEST_USER";
    echo "PWD: $TEST_PWD";
    echo "JOBID: $TEST_JOBID";
    echo "PROJECTID: $TEST_PROJECTID";

./getopts.sh -U devops@gmail.com -P xxxxxx -J 8a809e2496 -I 80e2ea54b231f

USER: devops@gmail.com
PWD: xxxxxx
JOBID: 8a809e2496
PROJECTID: 80e2ea54b231f

With getopt, it's more complicated, but it allows long options and "=".

    #!/bin/bash
    TEMP=$(getopt -n "$0" -a -l "user:,password:,jobid:,projectid:" -- -- "$@")

    [ $? -eq 0 ] || exit

    eval set --  "$TEMP"

    while [ $# -gt 0 ]
    do
             case "$1" in
                    --user) TEST_USER="$2"; shift;;
                    --password) TEST_PWD="$2"; shift;;
                    --jobid) TEST_JOBID="$2"; shift;;
                    --projectid) TEST_PROJECTID="$2"; shift;;
                    --) shift;;
             esac
             shift;
    done
    echo "USER: $TEST_USER";
    echo "PWD: $TEST_PWD";
    echo "JOBID: $TEST_JOBID";
    echo "PROJECTID: $TEST_PROJECTID";

Some tests:

$ ./test.sh -user=jules -password=kabas -jobid 5555 -projectid 999 -c
./test.sh: unrecognized option '-c'

$ ./test.sh -user=jules -password=kabas -jobid 5555 -projectid 999   
USER: jules
PWD: kabas
JOBID: 5555
PROJECTID: 999
