Can I connect to the QlikView through QMS API authentication using Basic Authentication

Hi all,

An example of a request for PL / SQL:

DECLARE

l_Http_Request Utl_Http.Req;

l_Http_Response Utl_Http.Resp;

l_Buffer_Size NUMBER(10) := 512;

l_Line_Size NUMBER(10) := 50;

l_Lines_Count NUMBER(10) := 100;

l_String_Request VARCHAR2(32767);

l_Line VARCHAR2(128);

l_Substring_Msg VARCHAR2(512);

l_Raw_Data RAW(512);

l_Clob_Response CLOB;

l_Host_Name VARCHAR2(128) := 'real';

l_Port VARCHAR2(128) := '4799';

BEGIN

l_String_Request := '<?xml version="1.0"?>

<system.web>

</system.web>

</appSettings>

<system.serviceModel>

</behaviorExtensions>

</extensions>

</behavior>

</endpointBehaviors>

</behaviors>

</client>

</system.serviceModel>

</configuration>';

l_Http_Request := Sys.Utl_Http.Begin_Request(Url => 'http://host:port/QMS/Service', Method => 'POST', Http_Version => Sys.Utl_Http.Http_Version_1_1);

Sys.Utl_Http.Set_Header(l_Http_Request, 'User-Agent', 'Mozilla/4.0');

Sys.Utl_Http.Set_Header(l_Http_Request, 'Content-Type', 'text/xml;charset=UTF-8');

Sys.Utl_Http.Set_Header(l_Http_Request, 'Content-Length', Length(l_String_Request));

<<request_Loop>>

FOR i IN 0 .. Ceil(Length(l_String_Request) / l_Buffer_Size) - 1

LOOP

l_Substring_Msg := Substr(l_String_Request, i * l_Buffer_Size + 1, l_Buffer_Size);

BEGIN

l_Raw_Data := Utl_Raw.Cast_To_Raw(l_Substring_Msg);

Utl_Http.Write_Raw(r => l_Http_Request, Data => l_Raw_Data);

EXCEPTION

WHEN No_Data_Found THEN

EXIT Request_Loop;

END;

END LOOP Request_Loop;

l_Http_Response := Sys.Utl_Http.Get_Response(l_Http_Request);

Sys.Dbms_Output.Put_Line('Response> status_code: "' || l_Http_Response.Status_Code || '"');

Sys.Dbms_Output.Put_Line('Response> reason_phrase: "' || l_Http_Response.Reason_Phrase || '"');

Sys.Dbms_Output.Put_Line('Response> http_version: "' || l_Http_Response.Http_Version || '"');

END;

Response:

Response> status_code: "401"

Response> reason_phrase: "Unauthorized"

Response> http_version: "HTTP/1.1"

I am trying to cause the EDX task.

Hi Ronnie!

Thanks a lot for replying.

But i already read this documentation, but the solution is not found.

Got a job that should be triggered on exteranal event (EDX), see screenshot

Trying to call this task using the API Management Service (see screenshot)

But to reach the API Management Service, i try with using PL/SQL block (see code above)

and every time i get the answer

Response> status_code: "401"

Response> reason_phrase: "Unauthorized"

Response> http_version: "HTTP/1.1"

Error says problem with authentication

Is the user running the code a member of the correct local group(s) on the Server?

Hell, Rob

Yes, he is a member of.

Server QlickView is running on Windows Server/

And every time I try using code PL /SQL trigger the problem (on EDX), whenever I stumble Authentication error/

For example:

DECLARE
    l_Clob CLOB;
BEGIN
    Debug_Pkg.Debug_On;
    l_Clob := Ntlm_Http_Pkg.Get_Response_Clob('http://host:4799/QMS/Service', 'Domen\Makarenko', 'Password');
    Ntlm_Http_Pkg.End_Request;
    Debug_Pkg.Print(Substr(l_Clob, 1, 32000));
END;

This query returns a result

"Yes, he is a member of.

Server QlickView is running on Windows Server/"

Perhaps this is just a English translation problem, but the user id must be a member of the local groups "QlikView Management API"
