POSTMAN-TOKEN JMeter equivalent?

Question

I trying to craete HTTP request test for my server in JMeter.

sorry about the links for screenshots, I can't add a picture yet...

the next HTTP requests (of course before the logout) don't work (with the errors):

• create filter

Response code:400 Response message:Bad Request

• get all filters

Response code:Non HTTP response code: org.apache.http.ConnectionClosedException Response message:Non HTTP response message: Premature end of Content-Length delimited message body (expected: 53,145; received: 49,218)

org.apache.http.ConnectionClosedException: Premature end of Content-Length delimited message body (expected: 53,145; received: 49,218) at org.apache.http.impl.io.ContentLengthInputStream.read(ContentLengthInputStream.java:178) at org.apache.http.conn.EofSensorInputStream.read(EofSensorInputStream.java:135) at org.apache.http.conn.EofSensorInputStream.read(EofSensorInputStream.java:148) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.readResponse(HTTPSamplerBase.java:1936) at org.apache.jmeter.protocol.http.sampler.HTTPAbstractImpl.readResponse(HTTPAbstractImpl.java:476) at org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl.sample(HTTPHC4Impl.java:673) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerProxy.sample(HTTPSamplerProxy.java:66) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1296) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1285) at org.apache.jmeter.threads.JMeterThread.doSampling(JMeterThread.java:638) at org.apache.jmeter.threads.JMeterThread.executeSamplePackage(JMeterThread.java:558) at org.apache.jmeter.threads.JMeterThread.processSampler(JMeterThread.java:489) at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:256) at java.lang.Thread.run(Unknown Source)

these two HTTP requests work for me in postMan

createFilter postman screenshot (there is body too, but probably it's not the problem, I did copy-paste)

getAllFilters postman screenshot

edit:

As you can see in them both I have "POSTMAN-TOKEN" in the HTTP headers.

thanks to @Dmitri T I compared the requests from POSTMAN and after I add the "POSTMAN-TOKEN" with his value to JMeter all worked (read about it in this link: what-is-the-postman-token-header-attribute-in-generated-code-from-postman).

the POSTMAN-TOKEN calculated when request is sent. what is the JMeter equiualent?

Thanks!

thanks to @Dmitri T! work like a magic after this I saw it was answered here already: postman-script-to-jmeter-script

and one more online service (didn't checked): online-postman-to-jmeter-converter

You need to amend Google Drive permissions as the screenshots are not accessible.

In the meantime I can give you one generic hint: if the requests are "working" in Postman they will also "work" in JMeter given JMeter sends the same requests as Postman does.

• Either cross check request and pay attention to literally everything, URL, request body, request headers, etc. and it's better to use a 3rd-party sniffer tool like Fiddler or Burp as both tools don't show everything

• or just record the requests from Postman using JMeter's HTTP(S) Test Script Recorder like:

  1. Start the HTTP(S) Test Script Recorder
  2. Import JMeter's self-signed certificate into Postman if you're using HTTPS protocol
  3. Configure Postman to use JMeter as the proxy
  4. Run your request(s) in Postman
  5. JMeter will capture the requests and create the relevant HTTP Request samplers, HTTP Header Managers, etc.
