错误：“JSONArray文本必须以'['at 1 [character 2 line 1]”开头，不应该适用

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了错误：“JSONArray文本必须以'['at 1 [character 2 line 1]”开头，不应该适用相关的知识，希望对你有一定的参考价值。

我有一个通过JAXB初始化的ShipmentRequest类。

在我的主类中发送REST-API POST-Request我正在用所需的输入填充这个类的对象并将它放在JSONArray中

public JSONArray array = new JSONArray();
array.add(shipmentRequest);

最后我开始了POST：

HttpResponse<JsonNode> response = Unirest.post("https://someURL/services/rest/url")
.queryString("access_token","someTokenCode")
.body(array.get(0)).asJson();

我不明白错误，因为当我使用myJSONArray.toJSONString（）时，我得到以下输出：

[{"Id":"123456","Reference":"Send","transport":{"transporterCode":"Deliverer","trackAndTrace":"someCode123456"}}]

我错过了什么？我的第一个角色是'['？

编辑2：我的请求应该是这样的！

<ShipmentRequest xmlns="https://plazaapi.bol.com/services/xsd/v2.1/plazaapi.xsd">
 <OrderItemId>1234567890</OrderItemId>
 <ShipmentReference>A321SR</ShipmentReference>
 <Transport>
   <TransporterCode>TNT</TransporterCode>
   <TrackAndTrace>3SBOL0987654321</TrackAndTrace>
 </Transport>
</ShipmentRequest>

编辑3：我尝试使用以下方法填充JSONObject：

private JSONArray shipmentRequestArray = new JSONArray();
private JSONArray transportArray = new JSONArray();
private JSONObject requestObject = new JSONObject();

transportArray.add(new JSONObject().append("TransporterCode", transporter_Code));
transportArray.add(new JSONObject().append("TrackAndTrace", track_And_Trace));
shipmentRequestArray.add(new JSONObject().append("OrderItemId", orderItemIdTEST));
shipmentRequestArray.add(new JSONObject().append("ShipmentReference", shipment_Reference));
shipmentRequestArray.add(transportArray);

requestObject.put("ShipmentRequest", shipmentRequestArray);

当我尝试这个时：

.body(requestObject).asJson();

我收到新错误：没有为类org.codehaus.jettison.json.JSONObject找到序列化程序，也没有发现创建BeanSerializer的属性

编辑4：我的示例响应应如下所示：

答案

错误是关于错误的对象类型。第一个字符应该是'['，但它不是 - 我猜它'{'。

这是因为你正在执行array.get(0)，它返回一个JSONObject，需要JSONArray。

UPD：

我用你提供的其他信息做了一些调试。问题是Unirest.post返回RequestBodyEntity类的对象。要将其转换为json，您需要首先通过getBody()获得答案。

这对我有用：

ShipmentRequest shipmentRequest = new ShipmentRequest();
shipmentRequest.setOrderItemId("1234567890");
shipmentRequest.setShipmentReference("A321SR");
ShipmentRequest.Transport transport = new ShipmentRequest.Transport();
transport.setTrackAndTrace("3SBOL0987654321");
transport.setTransporterCode("TNT");
shipmentRequest.setTransport(transport);

String jsonRequest = new Gson().toJson(shipmentRequest);
RequestBodyEntity result = Unirest.post("https://plazaapi.bol.com/services/rest/shipments/v2")
    .queryString(
       "access_token",
       "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjaWQiOjMzMTgsInNlcSI6MSwidHlwIjoiYXBpIiwidnNuIjoxLCJuYmYiOjE1MTcyOTc2NjF9.hVdtwBfJAVfRVeBdf1XDAxe7Qpigwa0wmCvnF_Bicc8")
    .body(jsonRequest);
System.out.println(new Gson().fromJson(result.getBody().toString(), ShipmentRequest.class));

你需要使用result.getBody()返回你想要的对象。在此之后你可以做到

System.out.println(result.getBody().toString())

打印或

new Gson().fromJson(result.getBody().toString(), ShipmentRequest.class)

将其保存到ShipmentRequest类型的对象中。
