How to make a cURL request with a specific content type header?

To make a cURL request with a specific content type header, you can use the -H or --header flag followed by the content type header. Here's an example command:

curl -H "Content-Type: application/json" -X POST -d '{"name": "John", "age": 30}' http://example.com/api

In this example, the content type header is set to "application/json". The -X flag is used to specify the HTTP method (POST in this case) and the -d flag is used to include the request body in the cURL request. Replace http://example.com/api with the actual endpoint you want to access.
