using curl with -d param1=value1 seems not work properly - linux

Question

I have a shell Unix running every hour (crontab on CentOS 7).
Inside that shell, a loop read and proceed treatment for all new files find in a defined folder.
At the end of each files's treatment a CURL command is send with some parameters, for example :
curl https://aaaaaa.com/website -d param1=value1 -d param2=value2 ....
Each time the shell is run by crontab, the 1st CURL is correctly converted to a true URL and received by Apache/Tomcat, but all the others are bad. In fact the 2nd and the following CURLs seem not converted in the correct format like
https://aaaaaa.com/website?param1=value1&param2=value2
but they are sent like
https://aaaaaa.com/website -d param1=value1 -d param2=value2
So the website is unable to treat the parameters properly.
Why the 1st command is correctly converted to a correct URL format and not the following ?

You need to provide the "-d" flags and values before the URL so:
curl -d param1=value1 -d param2=value2 https://aaaaaa.com/website
Moreover, this command is going to send the parameters/values as POST parameters, not query parameters. You can use the "-G" flag, possibly combined with "--url-encode" to send as query parameters, see:
