通過REST API獲取數據時java.lang.IllegalArgumentException的問題

我嘗試使用REST API並嘗試連接到服務器並使用Java獲取數據。我開發了一些代碼;通過REST API獲取數據時java.lang.IllegalArgumentException的問題

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);

我在上面最後一句之後得到一個異常;

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

我使用的應用「捲曲」，也就是在命令行上爲REST-API有用，並用相同的URL容易得到的數據。但是，我無法在Java上做到這一點。網址有問題嗎？請糾正我，因爲我沒有看到任何錯誤的代碼。

你不需要在查詢參數前的末尾添加'backslash'，即它應該像'https：// XXX/0/devices/2c5a7b88-1eca-48b3-ae68-cdcb011a84d9/s /汽車存在？最新= 2' – Satendra

從URL中刪除\\。它不應該在那裏。只使用?來啓動查詢字符串。
