Question

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

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

这个api返回一个json响应。我需要使用泽西客户端提供有效负载，这就是我被困住的地方。 FOllowing是我需要提供的有效载荷的样本提取（最好是字符串）

问题是如何将有效负载（XML / JSON）作为字符串或实体提供给我的webtarget。

我看到了提供calden How to send Request payload to REST API in java?提到的有效载荷的答案，但我正在寻找一种方法在泽西客户端中进行。

这是我的代码，直到现在，它不能完全用于发布请求。

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);
}

}

Answer 1

您指定payload作为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));

我使用以下代码完成了这项工作，Salil的代码工作得很好（+1感谢他），感谢所有为此问题做出贡献的人，喜欢stackoverflow：

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 :             
                    String payload = "\r\n{\r\n\"query\": \"google \",\r\n\"rows\": 50,\r\n\"return_docs\": true,\r\n\"is_facet\": true\r\n}"; //this is escapped json string in single line
                    config = new ClientConfig();
                    client = ClientBuilder.newClient(config);
                    target = client.target("http://localhost:7400/searchws/search/getresults");
                    response = target.request().accept(MediaType.APPLICATION_JSON).post(Entity.entity(payload, MediaType.APPLICATION_JSON), Response.class);
                    processresponse(response); //This could be any method which processes your json response and gets you your desired data.
                    System.out.println(response.readEntity(String.class));
                    break;
                case GET :
                    config = new ClientConfig();
                    client = ClientBuilder.newClient(config);
                    target = client.target("http://localhost:7400/search-service/searchservice").path("search").path("results").path("tiger");
                    response = target.request().accept(MediaType.APPLICATION_JSON).get();
                    processresponse(response); //This could be any method which processes your json response and gets you your desired data.
                    System.out.println(response.readEntity(String.class));
            }

}

需要Jersey客户端api方式发布带有json有效负载和标头的webrequest
