Hello Ajay,

Hi Manish,

You can CONCATENATE string literals rite ?

There is a method available in webdynpro CL_WD_UTILITIES=>CONSTRUCT_WD_URL which creates the URL for a webdynpro application. Not sure if there is a method like what you are looking for.

Thanks,

Ajay Bose

CRVMANISH — Mon, 14 Oct 2013 06:28:56 GMT

Sreenivas,

Thanks for replying , this method will ultimately append field to URL.

URL data type is too short to accept it.

Manish

former_member219762 — Mon, 14 Oct 2013 10:02:50 GMT

Hi,

METHOD cl_http_client=>create_by_url

EXPORTING

url = http_url

Here url type is string so it is dynamic .Why it is not accepting more than 256 characters?

Regards,

Sreenivas.

Hi,

Split parameter stream and CONCATENATE that into another string type object and pass that object to url parameter of the method.

Sreenivas.

Hi Manish,

I don't think that the length of your request is the problem but the Blanks (Spaces) in your parameters. Parameters must always be URL encoded (spaces for example become "%20").

(for these kind of requests (so many parameters) a POST would be a more proper http method I think)

Best regards

Uwe

Check the Status message , requested URL is too long even i enforce it while debugging.

Helo

Assuming client to be an object of class CL_HTTP_CLIENT, you can send whaterver data (field name-value paris, plain data, compressed data, etc.) using this:

client->request->set_cdata( dummy ).

See report RSHTTP01 for an example.

/SaveJobNotification?Notificationid=''1234''&Priority=''CM HIGH''&NotificationType=''Corrective Maint.''&SystemStatus=''''&UserStatus=''Initial''&startdt=''20130203'''

* '&starttime=''122545''&enddt=''20130205''&endtime=''122545''&CodeGroup=''Meter Related Code''&Code=''Meter Install''' '&street=''Plot No 87,Sawarkar Nagar''&city=''Nagpur''&state=''Maharashatra''&country=''India''&zipcode=''440021''' INTO http_url.

How do i pass this data.

Hello Mansih,

just a question: do you know the difference between http GET and http POST?

Uwe

Re: Calling https:// long url from ABAP code IF_HTTP_CLIENT

CRVMANISH — Tue, 15 Oct 2013 09:02:30 GMT

Yes Uwe, I have been using it lot these days, this is already post method.

Issue is with only POST not GET Method.

Manish

UweFetzer_se38 — Tue, 15 Oct 2013 09:40:02 GMT

Ok, then you should already know that with a POST you shouldn't pass the parameters via URL but within the message body like Alejandro Mejias said.

On SCN and the ABAP documentation are enough examples on how to code this. Just search for "SET_FORM_FIELD" or "SET_CDATA".

Re: Calling https:// long url from ABAP code IF_HTTP_CLIENT

alejandro_mejias — Tue, 15 Oct 2013 09:46:31 GMT

In the request set content type application/x-www-form-urlencoded, so the request body uses the same format as the query string:

parameter=value&also=another

something like

	CALL METHOD client->request->set_header_field
	EXPORTING
	name = '`Content-Type`'
	value = '`application/x-www-form-urlencoded`'.

client->request->set_cdata( 'parameter=value&also=another&everythingconcatenatedas=stringtype' );

CRVMANISH — Tue, 15 Oct 2013 11:29:48 GMT

Well Uwe, i am using oData , in this parameters are passed via URL also.

Have you tried one of our suggestions yet?

Again: you cannot use Spaces within an URL.
