Adding JSON as a message body in a HTTP PUT request in Cygwin?

Question

I have the following JSON , which I have validated using JsonLint :

{
        "names": [
            {
                "id":"123",
                "name":"stubName",
                "type":"stubType",
            }
        ]
    }

I would like to add it as a message body in my CURL command (using Cygwin) in order to test a REST handler that I wrote.

I am currently using this command, which I created from reading this answer:

 curl -H "Content-Type: application/json" -X PUT -d '{
        "names": [
            {
                "id":"123",
                "name":"StubName",
                "type":"StubType",
            }
        ]
    }' localhost:9980/Id/123/version/123/addPerson

My handler is as follows:

            @PUT
            @Consumes("application/json")
            @Path("/Id/{Id}/version/{version}/addPerson")
            public Response addPerson(@PathParam("Id") String Id,
                                                    @PathParam("version") String version, 
                                                     @Context List<Name> names) {

            LOGGER.info("NAMES PASSED : {}", names.toString());

    }

When I try to hit my method using CURL I get an HTTP 400 method.

Edit: when I try to do names.toString() I get a null pointer, meaning that the names list must be null.

I'd suggest you try using the Postman app instead of cURL too — OneCricketeer, Dec 08 '16 at 15:22
@cricket_007 Sorry I added that by mistake, please see the actual path I am using — java123999, Dec 08 '16 at 15:23
I don't know what json library you've setup, but the `@Context` is intended for the request object, not the json document. Like, look at some of these examples http://stackoverflow.com/questions/7693669/how-to-post-a-json-object-to-a-jax-rs-service — OneCricketeer, Dec 08 '16 at 15:27

You should not use @Context The entity body (parameter) should be annotation-less.

 public Response addPerson(@PathParam("Id") String Id,
                           @PathParam("version") String version, 
                           List<Name> names) {

With a List<Name> you should be sending a JSON array. Get rid of the {"names":, and just send the []

curl -H "Content-Type: application/json" -X PUT -d '[
    {
        "id":"123",
        "name":"StubName",
        "type":"StubType",
    }
]' localhost:9980/Id/123/version/123/addPerson
