I may be way off base, but I've been trying all afternoon to run the curl post command in this recess PHP framework tutorial. What I don't understand is how is PHP supposed to interpret my POST, it always comes up as an empty array.
curl -i -X POST -d '{"screencast":{"subject":"tools"}}' \
http://localhost:3570/index.php/trainingServer/screencast.json
(The slash in there is just to make me not look like an idiot, but I executed this from windows using PHP 5.2, also tried on a Linux server, same version with Linux curl)
There must be something I'm missing because it seems pretty straightforward, the post just isn't be interpreted right, if it was, everything would work great.
This is what I get back:
HTTP/1.1 409 Conflict Date: Fri, 01 May 2009 22:03:00 GMT Server: Apache/2.2.8 (Win32) PHP/5.2.6 X-Powered-By: PHP/5.2.6 Transfer-Encoding: chunked Content-Type: text/html; charset=iso-8859-1 {"screencast":{"id":null,"subject":null,"body":null, "dataUrl":null,"dataMedium":null,"createdOn":null,"author":null}}
Normally the parameter -d
is interpreted as form-encoded. You need the -H
parameter:
curl -v -H "Content-Type: application/json" -X POST -d '{"screencast":{"subject":"tools"}}' \
http://localhost:3570/index.php/trainingServer/screencast.json
I believe you are getting an empty array because PHP is expecting the posted data to be in a Querystring format (key=value&key1=value1).
Try changing your curl request to:
curl -i -X POST -d 'json={"screencast":{"subject":"tools"}}' \
http://localhost:3570/index.php/trainingServer/screencast.json
and see if that helps any.
You should escape the quotes like this:
curl -i -X POST -d '{\"screencast\":{\"subject\":\"tools\"}}' \
http://localhost:3570/index.php/trainingServer/screencast.json
You need to set a few extra flags so that curl sends the data as JSON.
$ curl -H "Content-Type: application/json" \
-X POST \
-d '{"JSON": "HERE"}' \
http://localhost:3000/api/url
-H
