java - 错误: "A JSONArray text must start with ' [' at 1 [character 2 line 1]" should not apply

Question

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，我用所需的输入填充此类的对象并将其放入 JSONArray

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

最后我开始发帖:

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

我不明白这个错误，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？我的第一个字符是“[”？

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: 我尝试用这些填充 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);

当我尝试这样做时:

.body(requestObject).asJson();

我收到新错误: 找不到类 org.codehaus.jettison.json.JSONObject 的序列化程序，也没有发现用于创建 BeanSerializer 的属性

编辑4: 我的示例响应应如下所示:

Answer 1

错误是关于错误类型的对象。第一个字符应该是“[”，但事实并非如此——我猜是“{”。

这是因为您正在执行 array.get(0)，它会返回一个 JSONObject，其中需要 JSONArray。

更新:

我使用您提供的附加信息进行了一些调试。 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() 获取答案正文。

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));

您需要使用result.getBody()来返回您想要的对象。 之后你可以做

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

打印它或

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

将其保存到 ShipmentRequest 类型的对象中。
