json中的發佈請求RESTful

Question

我想在使用java的服務器中執行POST操作。

它正在使用xml，但不使用json。你可以幫我嗎？ 這個例子效果很好。

config = new ClientConfig(); 
client = ClientBuilder.newClient(config); 
target = client.target("http://192.168.1.156:5700/sdelab07-local").path("person"); 

String xmlRequest = "<person><firstname>ffff</firstname><healthProfile><value>89</value></healthProfile></person>"; 

response = target.request(MediaType.APPLICATION_XML_TYPE).post(Entity.xml(xmlRequest)); 
String xmlLine = response.readEntity(String.class); 
System.out.println(xmlLine); 

這個json的POST請求不起作用，爲什麼？

String jsonRequest = "{\"firstname\" : \"ffff\"," + 
          "\"healthProfile\" : {" + 
          "\"value\" : 51}}"; 

response = target.request(MediaType.APPLICATION_JSON_TYPE).post(Entity.json(jsonRequest)); 
String jsonLine = response.readEntity(String.class); 
System.out.println(jsonLine); 

我得到以下錯誤：

N/A (through reference chain: introsde.rest.ehealth.model.Person["healthProfile"])

我覺得我jsonRequest是在一個錯誤的格式。如果是這樣，那麼正確的應該是什麼？

我試圖現在在郵差中發佈郵件請求。身份證即使在那裏也不起作用。我在使用xml發佈時沒有問題。 使用JSON我得到以下信息（在郵差）：

Can not deserialize instance of introsde.rest.ehealth.model.LifeStatus out of START_ARRAY token at [Source: org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream@208dd233; line: 5, column: 31] (through reference chain: introsde.rest.ehealth.model.Person["healthProfile"])

這是我的Person類：

太謝謝你了！

Answer 1

JSON的正確的格式是：

{ 
    "person": { 
     "firstname": "ffff", 
     "healthProfile": { "value": "89" } 
     } 
} 

希望這可以幫助你
