How to pass dynamic headers to the Http Request in jMeter?

Question

There is a initial request going to the server which should retrieve the CSRF token and use that token id in post request header.

if that does not happen any POST requests to the server will return that error.

In the above screen shot, where token is the request to get the CSRF token Id, If I run the test this will generate one dynamic random token ID. But I need to pass the generated token ID in the post request through Header Manager. How can it possible. If yes, Can any one suggest some way to do that.

Answer 1

我通过使用用户定义的变量和正则表达式提取器将参数从一个请求采样器传递到另一个来解决它。

Answer 2

In the firs request add a postprocesor of the request. if the response is un json format user json Extractor, in json Extractor define a variable that read the token
