ptcontenttype - Content-Type Testing Tool

ptcontenttype tests whether changing the request Content-Type header influences the returned response Content-Type.

Installation

pip install ptcontenttype

Adding to PATH

If you're unable to invoke the script from your terminal, it's likely because it's not included in your PATH. You can resolve this issue by executing the following commands, depending on the shell you're using:

For Bash Users

echo "export PATH=\"`python3 -m site --user-base`/bin:\$PATH\"" >> ~/.bashrc
source ~/.bashrc

For ZSH Users

echo "export PATH=\"`python3 -m site --user-base`/bin:\$PATH\"" >> ~/.zshrc
source ~/.zshrc

Usage examples

ptcontenttype -u https://www.example.com/
ptcontenttype -u https://www.example.com/api -m POST -d '{"test":true}'
