jMeter - Extract Value from Variable

I am using jMeter to perform a stress test of a website. I need to pass a variable's value to the next Request.

The value can be seen as follows in the response body:

var _data = {};
_data["_as_csrf_token"] = "64da5d341c253c2a181796d2524e57c6502d906b";
jQuery.ajaxSetup({ data: _data, type: "POST" });

How should I use the Regular Expression Extractor to get this value?

Please use the following string to extract the data using ReEx Extractor.

_data\[\"_as_csrf_token\"\] \= \"(.+?)\"\;

As shown in the screenshot below Regular Expression Extractor Example In case you are worried about the data to be extracted. I would suggest using https://regexr.com/ The reason why i prefer this site is because it helps you with the cheatsheet as well.

Second question, why (.+?) why not anything else? The reason is that it matches every kind of text within the pattern. No need to worry about the special characters.

The relevant regular expression would be:

_data\["_as_csrf_token"\] = "(\w+)";

The easiest way is to use boundary extractor:

Set left to:

data["_as_csrf_token"] = "

And right to:

";

If you want to use regex extractor then use:

data\["_as_csrf_token"\] = "[^"]+?";
