我正在使用JAX-RS開發REST API。我跟着this tutorial,現在我正在運行應用程序。但是我的網址路徑有問題。如果用戶輸入的BASE_URI錯例如Grizzly JAX-RS不返回400錯誤請求
// Base URI the Grizzly HTTP server will listen on
public static final String BASE_URI = "http://localhost:8080/app/api/1.0
:灰熊的主要方法,在這裏我addded我自己這樣的路徑自動創建BASE_URI
"http://localhost:8080/ap/ap/1.0/path/to/myResourse/123"
灰熊返回
Not Found
Resource identified by path '/app/api/1.0/whatever/the/user/entered, does not exist.
Grizzly 2.3.28.
問題是,如果用戶輸入BASE_URI
正確的,但進入我的資源路徑錯了,灰熊不顯示「未找到資源」的消息,但只顯示黑屏與HTTP頭404。
那麼如何顯示一個400 Bad Request
,告訴用戶他向一個無效的URL請求?我如何更改Grizzly提供的默認錯誤消息?
我試過尋找創建自定義錯誤消息,包括ExceptionMappers,但我認爲這不是我正在尋找的。我能想到的一個解決方案是爲URL Path中的每個/
創建一個新類,但這不是一個非常優雅的方法......?
下面是從那裏獲取資源,然後我在我的API顯示
@Path("/path/to/myResourse")
public class ResourceService {
@GET
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON + "; charset=UTF-8")
public Response getBuildingSite(@PathParam("id") String id) throws Exception {
StringBuilder sb = new StringBuilder();
sb.append("https://www.exmaple.com/rest/api/resources");
sb.append(id);
sb.append(".xml");
String url = sb.toString();
try {
Resource resource = Connector.fetch(Resource.class, url);
return JSONMapper.asOkJsonResponse(resource);
} catch (Exception e) {
return JSONMapper.asErrorJsonResponse(
new ErrorResponse(404,"Resource '" + id + "' not found"));
}
}
}
