如何使用Jersey客户端POST方法提交数据

Question

我是新泽西州的新手。我需要实现一个Jersey客户端，才能使用POST方法提交数据。curl命令是：

curl -d '{"switch": "00:00:00:00:00:00:00:01", "name":"flow-mod-1", "priority":"32768", "ingress-port":"1","active":"true", "actions":"output=2"}' http://localhost:8080/wm/staticflowentrypusher/json

因此，我试图找出如何使用Jersey客户端来实现上述curl命令的方法。

到目前为止，我已经完成了：

public class FLClient {

private static Client client;
private static WebResource webResource;
private static String baseuri = "http://localhost:8080/wm/staticflowentrypusher/json";
private static ClientResponse response;
private static String output = null;

public static void main(String[] args) {
    try {

        client = Client.create();

        webResource = client.resource(baseuri);

                    // implement POST data

    } catch (Exception e) {
        e.printStackTrace();
    }
}

}

有人可以帮我吗？

现在我知道了。这是我的解决方案：

public static void main(String[] args) {

    try {
        Client client = Client.create();

        WebResource webResource = client.resource(baseuri);

        String input = "{\"switch\": \"00:00:00:00:00:00:00:01\", "
                + "\"name\":\"flow-mod-1\", \"priority\":\"32768\", "
                + "\"ingress-port\":\"1\",\"active\":\"true\", "
                + "\"actions\":\"output=2\"}";

        // POST method
        ClientResponse response = webResource.accept("application/json")
                .type("application/json").post(ClientResponse.class, input);

        // check response status code
        if (response.getStatus() != 200) {
            throw new RuntimeException("Failed : HTTP error code : "
                    + response.getStatus());
        }

        // display response
        String output = response.getEntity(String.class);
        System.out.println("Output from Server .... ");
        System.out.println(output + "\n");
    } catch (Exception e) {
        e.printStackTrace();
    }

}
