JMeter - Issues with Image Upload for API Request. Recording doesn't work

  1. If I upload an image on Postman using only binary option it works. If I use form-data to upload a file on Postman the image file gets corrupted with unnecessary appended info. So I tried to record JMeter script while uploading image on Postman using binary option. But the image size grew from 279kb to 509kb and I got a corrupt image. It's only 279kb when I send on Postman without recording. See pictures below.

  2. If I use the "Files Upload" tab on JMeter HTTP Request, it appends info as below making the image file corrupt. The JAVA implementation on Advanced tab doesn't work either. --WNAkrdOzMmE0iZxPNbdHVVPxuBwgUX Content-Disposition: form-data; name="source"; filename="fileupload.jpg" Content-Type: image/jpeg

Can someone please provide me Groovy or BeanShell code to upload multiple image files one by one? Or, if there is a way to capture the traffic properly without the image file getting corrupt with additional data, please let me know and I can try. Thanks. Same picture but bigger size when recording in JMeter

Original size when sending only from Postman using binary option

Solution

  • binary file upload means that the file is being send as the HTTP Post request body

    JMeter's equivalent configuration would be:

    1. Switch to the Files Upload tab of the HTTP Request sampler
    2. Provide full or relative path to the file you want to upload
    3. Other fields should remain intact
