Posted on by mimi51340

Hello,

I would like consume a webservice REST in AX2009 to track the shipment of our orders.

For this I used this example : Consuming REST APIs in Dynamics AX 2012 (folio3.com)

I modified for my case like this :

static void Job37(Args _args)
    {
    System.Net.HttpWebRequest webReq;

    System.Net.HttpWebResponse webRes;

    CLRObject clrObj;

    System.IO.Stream stream;

    System.IO.StreamReader streamRead;

    System.IO.StreamWriter streamWrite;

    System.Net.ServicePoint servicePt;

    System.Net.WebHeaderCollection headers = new System.Net.WebHeaderCollection();

   ;

   //This line gives the user control to run unmanaged and managed code

    new InteropPermission(InteropKind::ClrInterop).assert();

    // Create Object for adding headers

    headers = new System.Net.WebHeaderCollection();



    clrObj = System.Net.WebRequest::Create("https://api.dachser.com/rest/v2/shipmenthistory?tracking-number=4619790347927552&customer-id=231993665126400");

    webReq = clrObj;

    //Set Method Type

    webReq.set_Method("GET");

    webReq.set_KeepAlive(true);

    // Set Content type

    webReq.set_ContentType("application/xml");

    // Add Authorization code

    //headers.Add("Authorization", "sdfgvczzxcbtyfrvb");
    headers.Add("X-IBM-Client-Id", "clientId");
    headers.Add("Accept-Language", "en");
    headers.Add("accept", "application/json");

    //Add header to request

    webReq.set_Headers(headers);

    //Get Service Point

    servicePt = webReq.get_ServicePoint();

    servicePt.set_Expect100Continue(false);

    //Gets the response object

    webRes = webReq.GetResponse();

    //Get Stream

    stream = webRes.GetResponseStream();

    streamRead = new System.IO.StreamReader(stream);

    stream.Close();

    webRes.Close();

}

But the code exits on "webReq.set_Headers(headers);" line.

I don't know why. Please could you help me ?

Thanks a lot.

Hello,

It seems to work but now I exit without message at :

webRes = webReq.GetResponse();

Any idea ?

Thanks.

I don't see any obvious errors. You can try your luck with try/catch (If you can get error it will a lot easier)

Like below ? I don't get any message...

static void Job37(Args _args) { System.Net.HttpWebRequest webReq; System.Net.HttpWebResponse webRes; CLRObject clrObj; System.IO.Stream stream; System.IO.StreamReader streamRead; System.IO.StreamWriter streamWrite; System.Net.ServicePoint servicePt; System.Net.WebHeaderCollection headers = new System.Net.WebHeaderCollection(); ; try { //This line gives the user control to run unmanaged and managed code new InteropPermission(InteropKind::ClrInterop).assert(); // Create Object for adding headers headers = new System.Net.WebHeaderCollection(); clrObj = System.Net.WebRequest::Create("https://api.dachser.com/rest/v2/shipmenthistory?tracking-number=4619790347927552&customer-id=231993665126400"); webReq = clrObj; //Set Method Type webReq.set_Method("GET"); webReq.set_KeepAlive(true); // Set Content type webReq.set_ContentType("application/xml"); //Add header to request webReq.set_Headers(headers); // Add Authorization code //headers.Add("Authorization", "sdfgvczzxcbtyfrvb"); headers.Add("X-IBM-Client-Id", "clientId"); headers.Add("Accept-Language", "en"); headers.Add("accept", "application/json"); //Get Service Point servicePt = webReq.get_ServicePoint(); servicePt.set_Expect100Continue(false); //Gets the response object webRes = webReq.GetResponse(); //Get Stream stream = webRes.GetResponseStream(); streamRead = new System.IO.StreamReader(stream); stream.Close(); webRes.Close(); } catch (Exception::Error) { info("Caught 'Exception::Error'."); throw Exception::Error; } }

Nope You need catch CLRError.

catch (Exception::CLRError) { throw error(AifUtil::getClrErrorMessage()); } ---------OR---------- catch(Exception::CLRError) { ex = CLRInterop::getLastException();//ex-->System.Exception ex; info(ex.ToString()); }

Or if you have inner exception

catch(Exception::CLRError) { exc = CLRInterop::getLastException(); if( exc ) { clrExcMessage = exc.get_Message(); // BP Deviation Documented strError = CLRInterop::getAnyTypeForObject( clrExcMessage ); innerExc = exc.get_InnerException(); while(innerExc != null) { clrExcMessage = innerExc.get_Message(); // BP Deviation Documented strError = strError '\n' CLRInterop::getAnyTypeForObject( clrExcMessage ); innerExc = innerExc.get_InnerException(); } } }

Note: Right now I don't have a chance to check from ax 2009. I found this examples , on the internet after a few minutes of searching. But if you search for "catch" in system classes, you can find much more accurate examples.

Hello,

Thanks for your help.

Now I get an error :

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Net.WebException: The underlying connection has been closed : An unexpected error occurred on a send. ---> System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream. à System.Net.FixedSizeReader.ReadPacket(Byte[] buffer, Int32 offset, Int32 count) à System.Net.Security.SslState.StartReadFrame(Byte[] buffer, Int32 readBytes, AsyncProtocolRequest asyncRequest) à System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest) à System.Net.Security.SslState.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest) à System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest) à System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest) à System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult) à System.Net.TlsStream.CallProcessAuthentication(Object state) à System.Threading.ExecutionContext.runTryCode(Object userData) à System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) à System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) à System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) à System.Net.TlsStream.ProcessAuthentication(LazyAsyncResult result) à System.Net.TlsStream.Write(Byte[] buffer, Int32 offset, Int32 size) à System.Net.PooledStream.Write(Byte[] buffer, Int32 offset, Int32 size) à System.Net.ConnectStream.WriteHeaders(Boolean async) --- Fin de la trace de la pile d'exception interne --- à System.Net.HttpWebRequest.GetResponse() --- Fin de la trace de la pile d'exception interne --- à System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) à System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) à System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) à System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) à ClrBridgeImpl.InvokeClrInstanceMethod(ClrBridgeImpl* , ObjectWrapper* objectWrapper, Char* pszMethodName, Int32 argsLength, ObjectWrapper** arguments, Boolean* argsAreByRef, Boolean* isException)

Could you help me please ? I get the error on this line : webRes = webReq.GetResponse();

I tried directly on the API portal of the partner, The correct URL is for example :

clrObj = System.Net.WebRequest::Create("https://api.dachser.com/rest/v2/shipmenthistory?tracking-number=4572418880307200&customer-id=8305600968523776");

And headers :

headers.Add("Accept-Language", "application/json"); headers.Add("X-IBM-Client-Id", "ce4fcc672e2f154342e318e1fa674c78"); headers.Add("accept", "application/json");

Thank you very much.

You can find it using Web Browser. I checked it I think it's using tls 1.2.

Ax 2009 uses .Net framework 3.5. In the past, tls 1.2 was not used with this version. Later, this situation changed, but as far as I know, there was no change in the ax kernel (You can't see 1.2 among the types)

This has multiple solutions. I shared a solution I came across below but actually there was a simpler solution I was looking for.

Thanks, so I created a file ax32.exe.conf from client side.

I executed the job "TLS_check" and I get : TLS security level TLS 1.2 is allowed by AX.

But now in my program, I get another error, do you think I have forgotten something ?
