Обновления веб-API Java и MS CRM 2016

Question

У меня есть приложение Java, и я пытаюсь обновить возможность через веб-API CRM. Когда я пытаюсь использовать Нестандартный HTTP-метод, такой как PATCH (который необходим для обновления), и переопределяю его с помощью "X-HTTP-Method-Override", как я нашел его в различных примерах кода, он не работает.

Код для возможности обновления:

public int updateOpportunity(OpportunityDaoModel model) throws IOException, URISyntaxException {
JSONObject opportunity = new JSONObject();
opportunity.put("name", model.getTopic());

HttpURLConnection connection = null;
URL url = new URL(RESOURCE + "/api/data/"+API_VERSION+"/opportunities(" + model.getCrmguid() + ")");
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("X-HTTP-Method-Override", "PATCH");
connection.setRequestProperty("OData-MaxVersion", "4.0");
connection.setRequestProperty("OData-Version", "4.0");
connection.setRequestProperty("Accept", "application/json");
connection.addRequestProperty("Authorization", "Bearer " + token);
connection.setUseCaches(false);
connection.setRequestProperty("Content-Type", "application/json");
connection.setDoOutput(true);
connection.connect();

OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(opportunity.toString());
out.flush();
out.close();
int responseCode = connection.getResponseCode();
return responseCode;
}

После выполнения этого метода я получаю следующую ошибку:

{
 "error":{
   "code":"","message":"Unmapped Request found, PathTemplate:~/entityset/key, HttpVerb:POST","innererror":{
     "message":"Unmapped Request found, PathTemplate:~/entityset/key, HttpVerb:POST","type":"Microsoft.Crm.CrmHttpException","stacktrace":"   at Microsoft.Crm.Extensibility.OData.EntityController.HandleUnmappedRequest(ODataPath path)\r\n   at lambda_method(Closure , Object , Object[] )\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass10.<GetExecutor>b__9(Object instance, Object[] methodParameters)\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ExecuteAsync(HttpControllerContext controllerContext, IDictionary`2 arguments, CancellationToken cancellationToken)\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ApiControllerActionInvoker.<InvokeActionAsyncCore>d__0.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ActionFilterResult.<ExecuteAsync>d__2.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__1.MoveNext()"
   }
 }
}

После того, как я не нашел в Интернете никакой информации об этой ошибке, я попробовал другую запись и захотел использовать обновление одного атрибута через PUT. Это успешно выполняется для обычных атрибутов (например, атрибута name во многих объектах), но когда я пытаюсь обновить поле поиска, я получаю другую ошибку. Но сначала мой метод:

Код для обновления одного атрибута:

public int updateAttribute(String entity, String id, String attribute, String value) throws IOException, URISyntaxException {
JSONObject opportunity = new JSONObject();
HttpURLConnection connection = null;
String urlString = "";
if(attribute.contains("@odata.bind")) { // lookup value
    urlString = RESOURCE + "/api/data/"+API_VERSION+"/"+entity+"(" + id + ")";
        opportunity.put(attribute, value);
} else { // text value
        urlString = RESOURCE + "/api/data/"+API_VERSION+"/"+entity+"(" + id + ")/" + attribute;
        opportunity.put("value", value);
}
URL url = new URL(urlString);
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("PUT");
connection.setRequestProperty("OData-MaxVersion", "4.0");
connection.setRequestProperty("OData-Version", "4.0");
connection.setRequestProperty("Accept", "application/json");
connection.addRequestProperty("Authorization", "Bearer " + token);
connection.setUseCaches(false);
connection.setRequestProperty("Content-Type", "application/json");
connection.setDoOutput(true);
connection.connect();

OutputStreamWriter out = new     OutputStreamWriter(connection.getOutputStream());
out.write(opportunity.toString());
out.flush();
out.close();
int responseCode = connection.getResponseCode();
return responseCode;
}

я называю этот метод через

 updateAttribute("opportunities", model.getCrmguid(), "[e-mail]", "/entityendpointwiths("+model.getProgress()+")");

Сообщение об ошибке:

    }
  }
 }

Спасибо за любую помощь.

Если кто-то еще должен быть в этом положении, я рад представить вам мой ответ. Вместо использования заголовка x-http-override вы должны использовать HTTPPatch-Class java.

метод:

public String updateAttribute(String entity, String id, List<Map<String, Object>> parameters) throws IOException, URISyntaxException {
JSONObject object = new JSONObject();
    for (Map<String, Object> map : parameters) {
        for (Map.Entry<String, Object> entry : map.entrySet()) {
            String key = entry.getKey();
            Object value = entry.getValue();
            object.put(key, value);
        }
    }

    String urlString = "";
    urlString = RESOURCE + "/api/data/"+API_VERSION+"/"+entity+"(" + id + ")/";
    StringEntity stringEntity = new StringEntity(object.toString());

    URL url = new URL(urlString);
    HttpPatch httpPatch = new HttpPatch(urlString);
    httpPatch.addHeader("OData-MaxVersion", "4.0");
    httpPatch.addHeader("OData-Version", "4.0");
    httpPatch.addHeader("Accept", "application/json");
    httpPatch.addHeader("Authorization", "Bearer " + token);
    httpPatch.addHeader("Content-Type", "application/json");
    httpPatch.setEntity(stringEntity);

    CloseableHttpClient httpClient = HttpClients.createDefault();
    HttpResponse httpResponse = httpClient.execute(httpPatch);

int responseCode =  httpResponse.getStatusLine().getStatusCode();

if (responseCode > 299) {
    InputStream inputStream = httpResponse.getEntity().getContent();
    ByteArrayOutputStream result = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int length;
    while ((length = inputStream.read(buffer)) != -1) {
        result.write(buffer, 0, length);
    }

    throw new IOException(result.toString("UTF-8"));
}

return responseCode;
}

Вызов метода через:

List<Map<String,Object>> opportunityParameterList = new ArrayList<>();
Map<String, Object> opportunityParameters = new HashMap<>();      
opportunityParameters.put("name", opportunityDaoModel.getTopic());
opportunityParameters.put("[e-mail]", "/lookupentityendpoint("+opportunityDaoModel.getProgress()+")");
opportunityParameterList.add(opportunityParameters);
this.crmHelper.updateAttribute("opportunities", opportunityDaoModel.getCrmguid(), opportunityParameterList);
