I need to extract sesskey, mbParam and AuthToken values and send them as list in the next request body.
In the request these values are displayed as
["{\"jsessionid\":\"0000gPQCV4FJ1NQvB8d4Ifd_P9I\",\"mbparam\":\"hDu7DhU%2FjA81TEjwbREmytgqIItmUS4b6rhEojYtcalv0PUs6iaewmtZu6U%3D\",\"MP-AUTH-TOKEN\":\"4fU7Bg20sRRUikHnzmZKcC4ZPyCjVxJnmm7QMnSm6mfT7GlqnySQS2YP\"}"]
How to handle these values?

Answer 1

Use the following Regular Expression Extractor configuration:
Reference Name: anything meaningful, i.e. dynamicvalues
Regular Expresssion:
\["\{\\"jsessionid\\":\\"(.+?)\\",\\"mbparam\\":\\"(.+?)\\",\\"MP-AUTH-TOKEN\\":\\"(.+?)\\"\}"\]
Template: $1$$2$$3$
Refer Extracted values as:
${dynamicvalues_g1} - for jsessionid
${dynamicvalues_g2} - for mbparam
${dynamicvalues_g3} - for MP-AUTH-TOKEN
While developing your regular expression remember that you need to escape the following characters with a backslash:
[
{
\
}
]
Other special characters which need escaping are: .^$*+?()|
