string variable not substituted in multi-line string
The colon is the scope character: $scope:$variable. PowerShell thinks you are invoking the variable $password from the scope $user. You might be able to get away with a subexpression.
$user="arun"$password="1234*"@"{ "proxy": "http://$($user):$($password)@org.proxy.com:80", "https-proxy": "http://$($user):$($password)@org.proxy.com:80"}"@Or you could use the format operator
$user="arun"$password="1234*"@"{{ "proxy": "http://{0}:{1}@org.proxy.com:80", "https-proxy": "http://{0}:{1}@org.proxy.com:80"}}"@ -f $user, $passwordJust make sure you escape curly braces when using the format operator.
You could also escape the colon with a backtick
$jsonStr = @"{ "proxy": "http://$user`:$password@org.proxy.com:80", "https-proxy": "http://$user`:$password@org.proxy.com:80"}"@
