Qlikview Server and Restful API Conenctor

hbuchetmann — Sat, 16 Nov 2024 02:19:28 GMT

Hello together,

we still have installed the Qlikview Server Version 12.10.20200 in our company.

Recently i downloaded the newest availabe Qlikview Desktop application and tried out the latest Rest API Connector.

I managed to load data into the qlikview application with manually reloading the skript.

But when it try to update the application automatically with the the qlikview server management console , it alwas runs into an error. If i open the application and reload skript manually it works fine.

Do i have to update our server to use the rest api connection with it?

Or is it not possible to get data from API with the management console?

Can you provide the document log that will show the error you're seeing when trying to run the reload task from the QMC?

We always recommend using the same version of Qlikview Desktop as Qlikview Server.

Thanks,
Josh

That is the task log, we need the document log. Please see the following article which will show you how to enable the document log in Qlikview Desktop. After you've enabled the document log, try reloading the QVW again from the QMC and send us the log, that should give you a better idea why the reload is failing.

I think i narrowed the problem down. I installed the same Desktop Client Version as the Server.

When i now load the skript manually it runs into an error as well.

In the skript i first get a token with a /rest/login (method=post) and write this token into a variable :

CUSTOM CONNECT TO
"Provider=QvRestConnector.exe;url=https://...../rest/login;
timeout=30;
method=POST;

...

[rootkey]:
LOAD [token_type]&' '&[access_token] AS Token RESIDENT RestConnectorMasterTable;

RestConnectorMasterTable:
SQL SELECT
"token_type",
"accessToken"
FROM JSON (wrap on) "root";

Let v_Token = FieldValue('Token',1);

Then i put this Variable in a second API request with the variable as authorization:

CUSTOM CONNECT TO

"Provider=QvRestConnector.exe;url=https://.../rest/orders;
timeout=30;
method=GET;
httpProtocol=1.1;
isKeepAlive=1;
bodyEncoding=UTF-8;
sendExpect100Continue=1;
autoDetectResponseType=1;
checkResponseTypeOnTestConnection=1;
keyGenerationStrategy=3;
authSchema=anonymous;
skipServerCertificateValidation=0;
useCertificate=No;
certificateStoreLocation=CurrentUser;certificateStoreName=My;
queryParameters=statusFrom%27.2%1statusTo%27.2;
addMissingQueryParametersToFinalRequest=1;
queryHeaders=Authorization%2$(v_Token);
PaginationType=None;
allowResponseHeaders=0;
allowHttpsOnly=0;

This worked fine with the Desktop version August 19.

With the 12.1 Version the token request gets through, but then i get an "HTTP protocol error 401 (Unauthorized):" with the get /rest/orders.

The Token which is wirtten into the variable is very long.

Here an example:

Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImp0aSI6IjQwZTZjNjI5MjhlOTViNTUwOGFmYzM0MjlkYWFiN2E0N2Y4MDM2MGIyNjJkYzgyYjMyZGIzZmQ5MzdlMzgwYmVkMGYzMGMxY2JhZTJhY2Q4In0.eyJhdWQiOiIxIiwianRpIjoiNDBlNmM2MjkyOGU5NWI1NTA4YWZjMzQyOWRhYWI3YTQ3ZjgwMzYwYjI2MmRjODJiMzJkYjNmZDkzN2UzODBiZWQwZjMwYzFjYmFlMmFjZDgiLCJpYXQiOjE1NzAwNTQ4MDEsIm5iZiI6MTU3MDA1NDgwMSwiZXhwIjoxNTcwMTQxMjAxLCJzdWIiOiI0Iiwic2NvcGVzIjpbIioiXX0.cwb55kzmZ4iAql_jdlWDfHq8j5pHU3AoLTRwZWQVv1uuonIN1x1iaq--IU0d-QNfWOCkc3z61M9RKEd1cQ432-iOwX8OSzUPSDMAsuySNnPtiHBg3OgAniL2Kil0sxYQBLG-rCyGVn1g6yMrtHbrUEdjychmDSd3SY2-Am-ttS5VFd3XwA446hibznvse7LoZrAWSBxwoX_H1atjZ6rDizrn8x9Hu7AKCPmFaTuzA7SKPxvYA6SfFZJKQeg8wtOG8XwhDhsa7DIBbBzjmABvauMIrD-xyKp0bTPZ_FsF6XKs87b5q-n7r2a9A9bvAe6HctqA6oZvEY1-W_0fal8LQ5AfW6zwsv0M7t4Q4EfchdrllY7VfpubqC4Zbh27StilxXvdGVV8VG28nBKROC_icLFrkTzme3yN40T33cd3UqsIp78X2BCJD59x5JZ1kHhFaeNiMHLvN-ODE9wOWcoJ13vCRmuWKRpzFrUZqh9fkQwq0G80KlY6_mkFCmuDND0aiKbT8Dn21od0pRJ03irS_9qNiYtTC8OWYkNOAGhZ33EhwxfwX_xyM3C566L2ylGSWMh9p2EDcbbXfNsX0VpD3gfi2xAwJQMSV57dgBXAoShOXtoaoPpAeJNph50UKXQaRK0B-eAQmRfMGeUKGSYDFZfdnJlvILyKr-17cGofYKM

Any Suggestion how i can make this work again with the variable in

queryHeaders=Authorization%2$(v_Token);

Best I can do is the Help on things to be sure you have not missed something documented there, if you find something not working as documented, please submit a support case to use at that point, so we can address with R&D.

https://help.qlik.com/en-US/connectors/Subsystems/REST_connector_help/Content/Connectors_REST/Create-REST-connection/Create-REST-connection.htm

You mentioned version 12.10 as well, note support for 12.10 is ending in about 4 weeks as well and you should update to a new version to ensure future support.

Regards,
Brett

HI Brett,

we updated the Qlikview Server to the latest Version, now it works fine.

The Value inside $(v_Token) (the token) in the line: queryHeaders=Authorization%2$(v_Token);

is pulled correctly now.

It looks like the older Server Version handled Values inside a variable differently than the newest.

Thank you for your suggestions and help.

Best wishes from germany,

Hermann
