dynamic http header in receiver rest adapter

[kevin_chirinos]

Hi gurus,I have a problem when I try to put the dynamic http header. If I put a static value, the interface works fine, but if I change that value to a variable, the interface throws an error. If the dynamic configuration is checked, the value of the variable is correct. Please, any suggestions?

The code in the UDF:

DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION); 
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/REST","HeaderAuthorization");
conf.put(key1, token); 
return token;

Hello Kevin,

In the REST receiver communication channel under 'REST URL' Tab you can specify the pattern variable replacement correctly. Since the Authorization is generated dynamically the pattern variable replacement looks like. I could

Value Source: Adapter-Specific Attribute

Pattern element Name: Authorization

Adapter Specific Attribute: Custom Attribute

Attribute Name: Authorization

Also ensure in the UDF code the attribute name is changed from Header Authorization to Authorization only.

Now Under 'HTTP Headers' Tab you can specify the HTTP headers as below:

Header Name: Authorization

Value Pattern: Bearer {Authorization}

Thanks and Regards - Rajesh PS

rajeshps - I am facing similar problem

If I change everything to Authorization its not working

Working in case of any other keyword eg token,Auth etc.

But header attribute name should be "Authorization" as per API specification.

Can you try it with authorization instead... I mean if you use a small "a"

taran85 - Yes it will work if everything is set to authorization but when I set parameter in headers tab as Authorization its not working.

Please refer below screenshot for the same.

Hi Rajesh,

I tried same thing what you suggested above, but its not working for me.

Can you please advise what am missing here ?

DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/REST","Authorization");
conf.put(key1, var1);
return var1;

Hi Varun K:

I have the same issue as yours . Do you have resolved this issue ? Appreciate your reply !

[chetan_risbud]

Im facing exact same issue.

Can you confirm the solution.

[iker_espinosa]

That's OK.

I also get "Set HTTP Header Authorization to ***" but if you use xpi_inspector with that REST channel you would see that http authorization is correct.

Hi,

Please use HTTP Headers as below

Under "Pattern variable replacement" can you change it from Adapater specific to custom attribute.

If you still facing issue please add the error screenshot.

Hi Varun/Rajesh,

We have a similar requirement, where we need to pass the generated token value to the nwBPM flow as header. we have followed exactly the same process and UDF as mentioned in the blog and we are getting the error : "Server returned code: 415" and

" HTTP error occurred: Unsupported Media Type 8/11/2020 03:28:37.087 PMErrorMP: exception caught with cause com.sap.aii.adapter.rest.ejb.common.exception.HttpCallException: HTTP POST call to http://po url/bpm/pwccom/syscentricdevgooglesdmsc/TriggerUploadProxy?wsdl not successful. Unsupported Media Type"

Can you please share how did you fix this error.

This solution worked once I changed channel configurations as shown.workingconfig.jpg
