JMeter and Content Disposition

Question

I am trying to emulate POST for stress testing with JMeter.

The "standard" POST (done by browser or curl) looks like:

POST /foo/boo HTTP/1.1
User-Agent: curl/7.35.0
Host: localhost:4000
Accept: */*
Content-Length: 8376
Content-Type: multipart/form-data; boundary=------------------------9dec6d453f478def

--------------------------9dec6d453f478def
Content-Disposition: form-data; name="filedata"; filename="plan.jmx"
Content-Type: application/octet-stream
....

However the request after jmeter lacks the filename attribute of the Content-Disposition section:

POST /feedback/1.0/attack/ HTTP/1.1
Connection: keep-alive
Content-Length: 8331
Content-Type: multipart/form-data; boundary=qO2U87_27QtEGliQMv6ZGjIe6PnfEh1TX-RHAhJ
Host: localhost:4000
User-Agent: Apache-HttpClient/4.3.3 (java 1.5)

--qO2U87_27QtEGliQMv6ZGjIe6PnfEh1TX-RHAhJ
Content-Disposition: form-data; name="filedata"
....

I looked at the XML and jmeter config looks like:

      <elementProp name="HTTPsampler.Files" elementType="HTTPFileArgs">
        <collectionProp name="HTTPFileArgs.files">
          <elementProp name="/Users/alexey/Work/all-attacks.zip" elementType="HTTPFileArg">
            <stringProp name="File.path">plan.jmx</stringProp>
            <stringProp name="File.paramname">filedata</stringProp>
            <stringProp name="File.mimetype"></stringProp>
          </elementProp>
        </collectionProp>
      </elementProp>

What is the way of specifying the filename attribute of the Content-Disposition when using jmeter?

Answer 1

It should be as simple as:

1. Check Use multipart/form-data for POST

2. Provide full path to file and filedata as "Parameter Name"

   • HTTP Request

     

   • View Results Tree listener output

     

See Performance testing: Upload and Download Scenarios with Apache JMeter guide for comprehensive information on how to simulate file operations in your JMeter test.

Answer 2

If you want to add any header into your request then you can add by passing those values into Http Header Manager (it'll be a child element for Http request)

Content-Disposition: form-data; name="filedata"; filename="plan.jmx"

Here Pass Content-Disposition in Name filed of header manger and rest in value field (no need to pass : ). It'll add this header in your request.

Also, are you getting proper response while executing this request from Jmeter? If not, try to change the implementation to Java of Http Request
