如何使用Jersey客户端POST方法提交数据
问题内容：
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？
问题答案：
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();
}
}
