How to do HTTP-request/call with JSON payload from command-line?

Question

What's the easiest way to do a JSON call from the command-line? I have a website that does a JSON call to retrieve additional data.

The Request Payload as shown in Google Chrome looks like this:

{"version": "1.1", "method":"progr","id":2,"params":{"call":...} } 

It's about doing the call from (preferably) linux command line and retrieving the JSON content, not about parsing the incoming JSON data.

Answer 1

You could use wget as well:

wget -O- --post-data='{"some data to post..."}' \   --header='Content-Type:application/json' \   'http://www.example.com:9000/json' 

Calling wget with the option -O providing the - (space in between will be ignored, so it could also be written as -O -) to it as its value will cause wget to output the HTTP response directly to standard output instead into a file. The long option name for that is --output-document=file.

Answer 2

Use curl, assuming the data is POST'ed, something like

curl -X POST http://example.com/some/path -d '{"version": "1.1", "method":"progr","id":2,"params":{"call":...} }' 

If you're just retrieving the data with a GET , and don't need to send anything bar URL parameters, you'd just run curl http://example.com/some/path
