需要Jersey客户端api的方式来发布一个带有json负载和头的webrequest

Question

我正在使用jersey（org.glassfish.jersey.client.*)为我的一个REST API编写客户机。

api url为:http://localhost:5676/searchws/search/getresults(POST)

我看到了calden提到的提供有效负载的答案如何在Java中向REST API发送请求有效负载？但我正在寻找一种方法在新泽西客户端做到这一点。

这是我的代码，到目前为止，它不能完全工作的post请求。

public class RequestGenerator 
{

    private WebTarget target;
    private ClientConfig config;
    private Client client;
    private Response response;

    public RequestGenerator(Method RequestSendingMethod) throws Exception
    {
        switch (RequestSendingMethod)
        {
            case POST :
                config = new ClientConfig();
                client = ClientBuilder.newClient(config);
                target = client.target("http://localhost:5676/searchws").path("search").path("getresults");
                String payload = "{\"query\":\"(filter:(\\\"google\\\")) AND (count_options_availbale:[1 TO *])\"}"; //This is just a sample json payload actual one is pretty large
                response = target.request(MediaType.APPLICATION_JSON_TYPE).post(Entity.json("")); // What to do here
                String jsonLine = response.readEntity(String.class);
                System.out.println(jsonLine);
}

}

您可以将有效负载指定为entity.json的参数

 String payload = "{\"query\":\"(filter:(\\\"google\\\")) AND (count_options_availbale:[1 TO *])\"}";  
 response = target.request(MediaType.APPLICATION_JSON_TYPE).post(Entity.json(payload));
