Hi James,

There are plenty of classes starting with CL_HTTP_*. We were used cl_http_client and http_client classes for webservices purpose. Please try with this classes. Below are might be useful.

cl_http_client=>create_by_url

http_client->send

http_client->receive

http_client->close

To call a web service, you have to create a proxy in SAP (SE80, other object, enterprise services). See sap library http://help.sap.com/saphelp_nw70/helpdata/EN/02/265c3cf311070ae10000000a114084/frameset.htm.

What kind of header do you want to add??

HI Sandra ,

I create Client proxy from WSDL (.Net service) that my colleague

send to me and I call to it as follows

DATA: lo_client_proxy TYPE REF TO co_task_web_service.

     CALL METHOD lo_client_proxy->crt_task
        EXPORTING
          input  = ls_input
        IMPORTING
          output = ls_output.

but he told me that he want that I add additional data to the HTTP header as follows

Request.Headers.Add("X-FORS_BASED_A_APTED", "t");

How I can do that ?

if it not possible please let me know

Thanks and Regards

James

Hi James,

I would recommend to use the class CL_HTTP_CLIENT.

Here we have been provided with the method SET_HEADER_FIELD.

We can add extra information through this method.

Please revert if something is unclear.

Thanks,

Daya.

I don't think these guys recommending CL_HTTP_CLIENT understand the web service protocols. Since you are using a consumer proxy to call a web service method, then to add a message header field (SOAP envelope header), you need to use the web service runtime protocol WS_HEADER provided for that. You would access this through method IF_PROXY_BASIS~GET_PROTOCOL which is attached to your proxy object. See the documentation in the help files or for interface IF_WSPROTOCOL for an example.

Based on Brad answer, I could find one snippet of code in SDN:

HI ,

Thanks but this is for soap envelope and not for the HTTP header .

HI James ,

Unfortunately you cannot set any attributes on the HTTP header when you using Web service .
