我在java中使用Unirest和/ resolve请求来获取用户提供的轨道的ID。我的代码过去工作得很好，然后大约1-2个月前API返回：http://hastebin.com/ofidoxuyec.xml，这解释了为什么当我尝试解析响应时会发生这种情况：

它发生在我提供的任何链接上，甚至是API文档中的示例轨道。奇怪的是API响应代码是200，这意味着没有错误吗？
如果我只是输入API调用，那么API调用在任何浏览器中都可以正常工作。有任何想法吗？谢谢！
代码：
（title，author，id和streamUrl是正确声明的所有字段，我的SoundCloud客户端ID有效。我使用/ resolve文档中的示例链接仅用于测试）
try {
HttpResponse<JsonNode> response = Unirest.get("http://api.soundcloud.com/resolve?url=http://soundcloud.com/matas/hobnotropic&client_id=" + App.prefs.getSCClientId())
.header("accept", "application/json")
.asJson();
if(response.getStatus() != 200)
App.logger.warn("Soundcloud API returned error code " + response.getStatus() + " for the URL " + url);
JSONObject json = response.getBody().getObject();
title = json.getString("title");
author = json.getJSONObject("user").getString("username");
id = json.getInt("id") + "";
if(!json.getBoolean("streamable"))
throw new NotStreamableException(getSource(), url);
else
streamUrl = json.getString("stream_url");
} catch (UnirestException e) {
e.printStackTrace();
}
