java - 通过 REST-API 获取数据时有关 java.lang.IllegalArgumentException 的问题

Question

我尝试使用 REST API 并尝试连接到服务器并获取 Java 中的数据。 我开发了一些代码，例如；

Client client = Client.create();
WebResource webResource = client.resource("https://XXXX/0/devices/2c5a7b88-1eca-48b3-ae68-cdcb011a84d9/s/car-exists\\?latest=2");
WebResource.Builder builder = webResource.getRequestBuilder();
for (NewCookie c : cookies)
  builder = builder.cookie(c);
ClientResponse response = builder.accept("application/json").get(ClientResponse.class);

在上面最后一句之后我遇到了异常；

javax.faces.FacesException: #{XXX}: java.lang.IllegalArgumentException: Illegal character in path at index 117: https://XXX/0/devices/2c5a7b88-1eca-48b3-ae68-cdcb011a84d9/s/car-exists\?latest=2

我在命令行上使用了对 REST-API 有用的应用程序“curl”，并使用相同的 url 轻松获取数据。但是，我无法在 Java 上做到这一点。网址有问题吗？请纠正我，因为我发现该代码没有任何问题。

从 URL 中删除 \\。它不应该在那里。仅使用 ? 来启动查询字符串。
