sudo yum install curl
sudo apt install curlSimulate HTML form requests
If you need to use the Curl command to simulate a form request, you can use the -F option of the Curl command to create a POST request and use multipart/form-data for encoding.
The -F option allows you to specify multipart data, and the Curl command automatically sets the content type to multipart/form-data.
If you need to send multiple form fields, you can use the -F option multiple times to specify multiple data, and the format of the data is specified by the key-value pair of field=value.
For example, the following Curl command will simulate an HTML form to send data in two fields, the field website value is myfreax.com, the field email value is web@myfreax.com, and finally the URL of the specified request.
curl -X POST -F 'website=myfreax.com' -F 'email=web@myfreax.com' https://wwww.myfreax.com/contact.php
