Response headers with multiple value

Hi all,

I'm working on some REST messages  on another Apache project, Syncope. 
I'm having problems with some Response headers.
Currently we build the response using the following method. Consider the 
case we have multiple ERROR_CODE values, for example 
RequiredValuesMissing and InvalidValues:

         for (SyncopeClientException sce : ex.getExceptions()) {
             builder.header(RESTHeaders.ERROR_CODE, 
sce.getType().getHeaderValue());
             ...
         }

(https://github.com/apache/syncope/blob/1_2_X/core/src/main/java/org/apache/syncope/core/rest/utils/RestServiceExceptionMapper.java 
- row 156)

In our client, we get the response in this way:

         List<Object> exTypesInHeaders = 
response.getHeaders().get(RESTHeaders.ERROR_CODE);

(https://github.com/apache/syncope/blob/1_2_X/client/src/main/java/org/apache/syncope/client/rest/RestClientExceptionMapper.java 
- row 79)

At this point, if we try to access to exTypesInHeaders, we have a list 
containing only one entry, with value 
"RequiredValuesMissing,InvalidValues" (a string value).  What I'm 
expecting instead is a list containing two entries, the first one with 
value "RequiredValuesMissing" and the second one with value 
"InvalidValues".

Is there some problems with multi value headers?

Thanks,

Hi Sergey,

thanks for your help. I added this line in the createServiceInstance 
method of RestClientFactoryBean:

RestClientFactoryBeanWebClient.getConfig(WebClient.client(serviceInstance)).getRequestContext().put("org.apache.cxf.http.header.split", 
true);

and it worked!

Regards

Hi

See

https://jax-rs-spec.java.net/nonav/2.0-rev-a/apidocs/javax/ws/rs/core/Response.html#getHeaders()

It says that on the client side it is identical to getStringHeaders(), 
where a header with multiple values is concatenated. In some cases a 
single values may have commas, CXF was splitting by default originally 
but later on it became an optional (CXF-specific) feature, can be 
enabled by setting an

"org.apache.cxf.http.header.split" contextual property

HTH, Sergey
