[英]Why am I getting null values on the server side after sending a post request by Postman
[英]Sending POST request with POSTMAN to Java REST API and getting null values in the xml response
I am creating a REST Service in Java and now I am building the post method wich has 2 parameters that has to be inputted as xml in postman (for test) and get a response as xml in java and insert it in database.
對於初學者,我試圖將值作為查詢參數添加到 POSTMAN 中,並帶有鍵和值。 響應為 200,但 xml 為 CUI=null Mesaj=null
即使您在 Postman 中為兩個鍵添加了值,這兩個值都是 null。
它怎么能看到這些值? 這是 java 代碼:
@Stateless
@Path("/cererepost")
public class HelloWorldResource {
Resp x = new Resp();
@EJB
private NameStorageBean nameStorage;
/**
* Retrieves representation of an instance of helloworld.HelloWorldResource
* @return an instance of java.lang.String
*/
@POST
@Produces("application/xml")
@Consumes(MediaType.APPLICATION_XML)
public Response postMsg(@PathParam("cui") String cui, @PathParam("mesaj") String mesaj) {
String xmlString = "CUI=" + cui + " Mesaj=" + mesaj;
Response response = Response.status(200).type(MediaType.TEXT_XML).entity(xmlString).build();
return response;
}
}
我應該修改什么才能看到我在 postman 生成的 xml 中的帖子中發送的參數值?
提前致謝
@PathParam("cui") String cui
這一行顯示來自客戶端的值應該作為路徑參數傳遞,而不是查詢字符串,如下所示:
正確: /cererepost/some_value
如果要將它們作為服務器端的查詢字符串參數獲取, @PathParam("cui")
更改為@QueryParam("cui")
。
要了解query string
和path variables
之間的區別,請查看這篇文章。
