我的目标是创建一个OData查询，该查询仅获取"Value": 100000000,数据以用于Options数组中的最后一个条目。我只需要在响应数据中发送最后一个Option的Value字段，然后Java接收响应并进行一些处理。我不允许将整个响应发送到Java。
我正在尝试解析Global Option Sets中的数据。我在解析Options ComplexType时遇到问题，到目前为止，在我当前的查询中只能到达选项级别。
https://myorg.api.crm.dynamics.com/api/data/v9.0/GlobalOptionSetDefinitions(06d1a507-4d57-e911-a82a-000d3a1d5203)/Microsoft.Dynamics.CRM.OptionSetMetadata
当前示例响应如下。由于Options是ComplexType，因此我没有找到任何文档或指南可以为我提供正确的方法指导。如果可以按照我希望的方式来运行此OData查询，则最终可以用Java实现我的方案。

我能够用Java过滤JSON，但是我还是想先过滤OData以获得单个Value字段。
try {
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("https://myorg.api.crm.dynamics.com/api/data/v9.0/GlobalOptionSetDefinitions%28" +
optionSetGuidString +
"%29/Microsoft.Dynamics.CRM.OptionSetMetadata/Options")
.get()
.addHeader("Authorization", "Bearer " + accessToken)
.build();
Response response = client.newCall(request).execute();
String dataReturnedFromGetOptions = response.body().string();
JSONObject json = new JSONObject(dataReturnedFromGetOptions);
JSONArray jsonArray = (JSONArray) json.get("value");
JSONObject jsonObject = (JSONObject) jsonArray.get(jsonArray.length() - 1);
previousValue = jsonObject.getInt("Value");
}
catch (IOException e) { }
