How Configure Dynamic HTTP header in REST Receiver Channel

[venkatasap]

Hi All,

My scenario is PROXY to REST whereas Dynamic HTTP headers need to pass in Rest receiver channel, this header parameter.

We have write the udf for and passing the parameter values in the udf but , we confused how to configure the values in the REST refceiver channel .

UDF:

DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION); DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP","XHeaderName1"); DynamicConfigurationKey key2 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP","XHeaderName2"); DynamicConfigurationKey key3 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP","XHeaderName3"); DynamicConfigurationKey key4 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP","XHeaderName4"); DynamicConfigurationKey key5 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP","XHeaderName5"); conf.put(key1, var1); conf.put(key2,var2); conf.put(key3, var3); conf.put(key3, var4); conf.put(key3, var5); return "";

Hi,

Thanks for this explanation, i was able to pass the Authorization Parameters via Dynamic Configuration.

However, the value of the parameters are visible in the message audit log (RESTOUT_HTTP_HEADER).

Is there anyway the Authorization Parameters can be passed in the HTTP Header as masked ?

Anyway to do the same from REST Sender adapter? Basically I want to dynamically assign HTTP Header value which can get these values from PI Mapping result.

Hi S RAVINDER,

I am getting access_token from REST lookup and now I am trying to add dynamic attribute and assign it a value of the acquired access token....

Could you please help me here?

my UDF for dynamic config -

finally{ // 5. close the accessor in order to free resources. if (accessor!=null) accessor.close(); } //return token; //Dynamic Configuration DynamicConfiguration dynConf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION); DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/REST", "XHeaderName1"); dynConf.put(key, token); return "";

However, my UDF is giving error while testing -

Exception:[java.lang.NullPointerException: while trying to invoke the method com.sap.aii.mapping.api.DynamicConfiguration.put(com.sap.aii.mapping.api.DynamicConfigurationKey, java.lang.String) of a null object loaded from a local variable at slot 8] in class com.sap.xi.tf._MM_SFDC_RESTAPI_QUOTE_STATUS_UPSERT_REQ_V1_ method newAccessToken[com.sap.aii.mappingtool.tf7.rt.Context@30f2539]
See error logs for details

If I remove dynamic config line my code is giving me access_token value successfully..

How can I pass this access_token value to synamic attribute and later use it in REST receiver adapter to add custom http header value?
