我有一个 java 应用程序，我正在尝试通过 crm web api 更新一个机会。当我尝试使用像 PATCH 这样的非标准 HTTP 方法（这是更新所必需的）并用“X-HTTP-Method-Override”覆盖它时，就像我在各种示例代码中发现的那样，它不起作用。

机会更新的代码：

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;
}

执行此方法后，我收到以下错误：

{
 "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()"
   }
 }
}

在网上找不到任何有关此错误的信息后，我尝试了不同的条目并希望通过 PUT 使用单个属性更新。这对于普通属性（如许多实体上的 name 属性）成功，但是当我尝试更新查找字段时，我得到一个不同的错误。但首先我的方法：

单属性更新代码：

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;
}

我通过调用此方法

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

错误信息：

{
 "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()"
    }
  }
 }

感谢您的任何帮助。

如果其他人应该处于这个位置，我很高兴向您展示我的答案。您应该使用 java 的 HTTPPatch-Class 而不是使用 x-http-override 标头。

方法：

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;
}

通过以下方式调用方法：

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);
