问题
So in my Test Plan I have a Cookie Manager setup inside my Thread Group which sets a specific Cookie value for 1 Cookie. Let's call it, MYID. I'm trying to figure out a way to verify that this specific Cookie's value was used to complete this one HTTP Request, because if I set my MYID to a specific value *(which actually tells which web server to go to), say to "Server1", but Server1 is down, unavailable, etc... HAProxy should change this and send you to Server2.
So basically I want to try and make sure that Cookie MYID was equal to "Server1" all the way through the HTTP Request.
I am trying to use a BeanShell PostProcessor to verify the Cookie's value after the request is ran, but when I tried using some code I have inside a PreProcessor that sets a cookie in a different Test Plan of mine I get an error saying:
Error Message:
Typed variable declaration : Attempt to resolve method: getCookieManager() on undefined variable or class name: sampler
And below here is the Code slightly modified from a BeanShell PreProcessor in another Test Plan I have...
CODE:
import org.apache.jmeter.protocol.http.control.Cookie;
import org.apache.jmeter.protocol.http.control.CookieManager;
CookieManager manager = sampler.getCookieManager();
for (int i = 0; i < manager.getCookieCount(); i++) {
Cookie cookie = manager.get(i);
if (cookie.getName().equals("MYID")) {
if (cookie.getValue().equals("Server1")) {
log.info("OK: The Cookie contained the Correct Server Number...");
} else {
log.info("ERROR: The Cookie did NOT contain the Correct Server Number...");
}
break;
}
}
For the error, I was thinking the "sampler" object was no longer available since the Request was already run, or something along those lines, but I'm not sure...
Or, is there another JMeter object I should be using instead of the "BeanShell PostProcessor" in order to verify the Cookie's value was correct..?
Any thoughts or suggestion would be greatly appreciated!
Thanks in Advance,
Matt
回答1:
If you trying to get cookie manager from the parent sampler in the Beanshell PostProcessor - you need to use ctx.getCurrentSampler(), not "sampler" as it is not exposed in script variables.
So just change this line:
CookieManager manager = sampler.getCookieManager();
to
CookieManager manager = ctx.getCurrentSampler().getCookieManager();
And your script should start working as you expect.
ctx
is a shorthand to JMeterContext instance and getCurrentSampler()
method name is self-explanatory.
