API testing using Jmeter

Question

I am trying to do some API testing in Jmeter. I was trying to follow this https://octoperf.com/blog/2018/04/23/jmeter-rest-api-testing/ . But I need to get token from cookie.

Can anyone suggest me a solution? Using Jmeter version 5.0

Sorry, if this question was asked previously. But, I could't find a solution.

Answer 1

Normally APIs don't use cookies so my expectation is that you need to extract HTTP Header value instead

1. Take a look at Response Data -> Response Headers mode of the View Results Tree listener and locate the value you need to extract.

   

2. Add Regular Expression Extractor as a child of the request and use the relevant regular expression in order to extract the interesting value. For example:

   • In order to extract gws from Server: gws header the regular expression would be Server: (.*)

   • In order to extract 1P_JAR cookie value the regular expression would be 1P_JAR=(.+?);

   • Don't forget to change Regular Expression Extractor's "Field to check" to Response Headers

Add the next line to user.properties file (located in the "bin" folder of your JMeter installation)

CookieManager.save.cookies=true Restart JMeter to pick the property up Add HTTP Cookie Manager to your Test Plan Now you should be able to refer cookie values as:

${COOKIE_session} and ${COOKIE__xsrf} CHk More info https://stackoverflow.com/questions/45520455/how-can-i-extraxt-session-id-and-xsrf-token-through-cookies-in-jmeter
