通过RESTAPI Java从URL获取ObjectID

我尝试将讨论添加到用户故事中。部分代码

        QueryResponse storyQueryResponse = restApi.query(storyRequest);
        JsonObject storyJsonObject = storyQueryResponse.getResults().get(0).getAsJsonObject();
        String storyRef = storyJsonObject.get("_ref").toString();
        System.out.println("Ref: " + storyRef);

        Ref ref = new Ref();
        System.out.println(ref.getOidFromRef(storyRef));
        System.out.println(ref.isRef(storyRef));

        createDis.addProperty("Artifact", ref.getOidFromRef(storyRef));
        createDis.addProperty("Text", "Java-Java-Java-Java-Java-Java-Java-Java-Java-Java-Java-Java");
        CreateRequest createRequest = new CreateRequest("ConversationPost", createDis);
        CreateResponse createResponse = restApi.create(createRequest);

System.out.println（“Ref:+storyRef”）返回 参考号：“

ref.getOidFromRef（storyRef）返回NULL ref.isRef（storyRef）返回FALSE

为什么？

此行无效，导致您的ref周围有一组额外的引号：

String storyRef = storyJsonObject.get("_ref").toString();

将其更改为此应能使其正常工作：

String storyRef = storyJsonObject.get("_ref").getAsString();

始终使用getAs方法，而不是toString
