如何使用 Jersey 客户端 POST 方法提交数据 [英] How to submit data with Jersey client POST method

问题描述

我是泽西岛的新手.我需要实现一个 Jersey 客户端来使用 POST 方法提交数据.curl命令是:

I am new to Jersey. I need to implement a Jersey client to submit data with POST method. The curl command is:

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

所以我想弄清楚如何使用 Jersey 客户端来实现上面的 curl 命令.

So I am trying to figure out how to use Jersey client to implement the above curl command.

到目前为止我已经完成了:

So far I have done:

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?

推荐答案

现在我想通了.这是我的解决方案:

Now I figure it out. Here is my solution:

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

}
