Json數據沒有正確地從URL讀取

我想從url讀取Json數據。在下面的json格式中，不能正確地從鏈接讀取jsonObject。我有代碼實現，但仍然出現錯誤。需要一些關於錯誤的幫助。請注意，我沒有創建任何模型類來解析json數據，而是直接從URL調用，然後在控制檯中打印該json數據。Json數據沒有正確地從URL讀取

JSON數據：

[ 
    { 
     "countryId": "BE", 
     "vat": 0.21, 
     "maxShortestEdge": 60, 
     "maxMiddleEdge": 80, 
     "maxLongestEdge": 200, 
     "maxLengthGirth": 300, 
     "maxWeight": 40, 
     "languages": [ 
      "fr", 
      "nl", 
      "en" 
     ], 
     "defaultLanguage": "nl", 
     "currency": { 
      "id": "EUR", 
      "messageId": "general.units.currency.eur" 
     } 
    }, 
    { 
     "countryId": "DE", 
     "vat": 0.19, 
     "maxShortestEdge": 60, 
     "maxMiddleEdge": 80, 
     "maxLongestEdge": 200, 
     "maxLengthGirth": 300, 
     "maxWeight": 40, 
     "languages": [ 
      "de", 
      "en" 
     ], 
     "defaultLanguage": "de", 
     "currency": { 
      "id": "EUR", 
      "messageId": "general.units.currency.eur" 
     }, 
     "tracking": { 
      "google": "UA-64686897-5", 
      "facebook": "591925420983129" 
     } 
    }, 
    { 
     "countryId": "LU", 
     "vat": 0.17, 
     "maxShortestEdge": 60, 
     "maxMiddleEdge": 80, 
     "maxLongestEdge": 200, 
     "maxLengthGirth": 300, 
     "maxWeight": 40, 
     "languages": [ 
      "fr", 
      "en" 
     ], 
     "defaultLanguage": "fr", 
     "currency": { 
      "id": "EUR", 
      "messageId": "general.units.currency.eur" 
     } 
    } 
]

代碼實現：

public class RestTest { 

    public static void main(String[] args) { 
     Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy.xxxxx.com",8080)); 

     try { 

      URL url = new URL("http://test.one.de/api/"); 
      HttpURLConnection http = (HttpURLConnection)url.openConnection(proxy); 
      InputStream ins = http.getInputStream(); 
      JsonParser jsonParser = new JsonParser(); 
      JsonObject jsonObject = (JsonObject)jsonParser.parse(new InputStreamReader(ins)); 
      System.out.println(jsonObject); 
     } 
     catch (MalformedURLException e) 
     { 
      e.printStackTrace(); 
     } catch (IOException e) { 

      e.printStackTrace(); 
     } 

    } 

}

錯誤獲取：

此鏈接應該是對您有用https://stackoverflow.com/questions/2591098/how-to-parse-json-in-java – Vignajeth

嘗試使用JsonArray而不是JsonObject。你可以嘗試讀取字符串，然後將其轉換

String json = IOUtils.toString(ins, encoding); 
JsonArray jsonArray = new JsonArray(json);

您可以使用ObjectMapper作爲替代：

ObjectMapper mapper = new ObjectMapper(); 
    JsonNode node = mapper.readTree(json); 
    System.out.print(node.get(0).get("countryId").asText()); //getting countryId of the first object in array

你可以用下面的代碼來分析它

S飾

納克url =「http://qs.gls-one.de/api/countries/origin/configurations」;

CloseableHttpClient client = HttpClientBuilder.create().build(); 
HttpGet post = new HttpGet(url); 
HttpResponse response = client.execute(post); 
System.out.println("Response Code : " 
       + response.getStatusLine().getStatusCode()); 

String response2= EntityUtils.toString(response.getEntity(), "UTF-8"); 
JSONArray jsonArray = new JSONArray(response2); 
System.out.println(jsonArray);

}
