curl author Daniel Stenberg plans to add native JSON support to curl

Recently, curl author Daniel Stenberg plans to add native JSON support to curl,
and gave three reasons.

• Sending JSON is common practice in areas like REST APIs
• "Easy to use JSON" is a common answer when asked about the considerations people choose for curl alternatives
• On sites like Stack Overflow, many people can't use curl to send correct JSON and quote JSON correctly because JSON uses double quotes and the shell doesn't expand variables within single quotes

Daniel said that since he doesn't send JSON very often, it was not appropriate for him to design this feature entirely. He needs more help from others to make this feature as useful as possible.

In short, Daniel plans to add two command line options:

• Send formatted JSON as a shortcut for -d with matching Accept header
• Build JSON request body for sending

Currently Daniel has drafted his updated concepts in the curl wiki and created a discussion board. Interested friends can actively participate in the discussion.
