Обновления веб-API Java и MS CRM 2016

Question

У меня есть приложение java, и я пытаюсь обновить возможность через crm web api. Когда я пытаюсь использовать нестандартный HTTP-метод, такой как PATCH (который необходим для обновления) и переопределяет его с помощью «X-HTTP-Method-Override», как я нашел его в разных примерах кода, он не работает.

код для обновления возможностей:

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 следующее сообщение об ошибке:

{ 
"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 информации для этой ошибки я попытался другой записи и хотел использовать обновление одного атрибута через PUT. Это удается для обычных атрибутов (например, атрибута name для многих объектов), но когда я пытаюсь обновить поле поиска, я получаю другую ошибку. Но первый 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 с помощью

updateAttribute("opportunities", model.getCrmguid(), "lookupentityid@odata.bind", "/entityendpointwiths("+model.getProgress()+")"); 

Сообщение об ошибке:

"error":{ 
    "code":"","message":"Operation not supported on opportunity","innererror":{ 
    "message":"Operation not supported on opportunity","type":"Microsoft.Crm.CrmHttpException","stacktrace":" at Microsoft.Crm.Extensibility.OData.EntityController.PutEntity(String entityName, String key, EdmEntityObject entity)\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()" 
    } 
    } 
} 

Спасибо за любой Помогите.

С наилучшими пожеланиями, Деннис

Если кто-то должен быть в этом положении я рад представить вам мой ответ. Вместо использования заголовка x-http-override вы должны использовать HTTPPatch-класс 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 с помощью:

List<Map<String,Object>> opportunityParameterList = new ArrayList<>(); 
Map<String, Object> opportunityParameters = new HashMap<>();  
opportunityParameters.put("name", opportunityDaoModel.getTopic()); 
opportunityParameters.put("lookupfield@odata.bind", "/lookupentityendpoint("+opportunityDaoModel.getProgress()+")"); 
opportunityParameterList.add(opportunityParameters); 
this.crmHelper.updateAttribute("opportunities", opportunityDaoModel.getCrmguid(), opportunityParameterList);
