Assistance Needed with Special Characters in HTTP Request Sampler - JMeter 5.6.3

[Selvah]

Hi everyone,

I'm using JMeter for practice purposes and encountering an issue with the HTTP Request Sampler in my Test Plan. I'm attempting to log in to a web application, but my username and password contain special characters ("@" and "#"). JMeter is converting these characters to their URL-encoded forms ("%40" and "%23"), which causes the login to fail.

Additionally, I am unable to enable the Body Data option in my HTTP Sampler. My current JMeter version is 5.6.3.

Could anyone please assist me with enabling the Body Data feature or provide guidance on how to properly use special characters in the username and password fields?

Thank you in advance for your help!

Best Regards.,

Karpaga Selvan M.

Change "Implementation" of the HTTP Request sampler to Java, the setting lives under "Advanced" tab.

If you have more than 1 HTTP Request sampler and want to apply the change to all of them - go for HTTP Request Defaults
