JSON Question

How to POST JSON data with Curl from Terminal/Commandline to Test Spring REST?

I use Ubuntu and installed Curl on it. I want to test my Spring REST application with Curl. I wrote my POST code at Java side however I want to test it with Curl. I am trying post a JSON data. An example data is like this:

{"value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Configuration Deneme 3","version":0,"systemId":3,"active":true}


I use this command:

curl -i \
-H "Accept: application/json" \
-H "X-HTTP-Method-Override: PUT" \
-X POST -d "value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Configuration Deneme 3","version":0,"systemId":3,"active":true \
http://localhost:8080/xx/xxx/xxxx


It returns this error:

HTTP/1.1 415 Unsupported Media Type
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=utf-8
Content-Length: 1051
Date: Wed, 24 Aug 2011 08:50:17 GMT


The error description is this:


The server refused this request because the request entity is in a format not supported by the requested resource for the requested method ().


Tomcat log:
"POST /ui/webapp/conf/clear HTTP/1.1" 415 1051

Any ideas about the right format of the Curl command?

EDIT:

This is my Java side PUT code (I have tested GET and DELETE and they works)

@RequestMapping(method = RequestMethod.PUT)
public Configuration updateConfiguration(HttpServletResponse response, @RequestBody Configuration configuration) { //consider @Valid tag
configuration.setName("PUT worked");
//todo If error occurs response.sendError(HttpServletResponse.SC_NOT_FOUND);
return configuration;
}

Answer

You need to set your content-type to application/json. But -d sends the Content-Type application/x-www-form-urlencoded, which is not accepted on Spring's side.

Looking at the curl man page, I think you can use -H:

-H "Content-Type: application/json"

Full example:

curl -H "Content-Type: application/json" -X POST -d '{"username":"xyz","password":"xyz"}' http://localhost:3000/api/login
