Hi Manish,

What is the problem you are facing ?

Hello Ajay,

http_url is of string type but my URL has more than 255 chars

I want to ask is their any other method to pass parameter data to my http request in the format which i mentioned in url.

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

Hi ,

Use   IF_HTTP_CLIENT~APPEND_FIELD_URL .

Sreenivas.

[CRVMANISH]

Sreenivas,

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

URL  data type is too short to accept it.

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.

[CRVMANISH]

Although it is dynamic , it is not accepting more than 256 , is their any basis setting

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

[CRVMANISH]

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.

[CRVMANISH]

/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.

Manish

Hello Mansih,

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

Uwe

[CRVMANISH]

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

Issue is with only POST not GET Method.

Regards

Manish

[UweFetzer_se38]

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".

[alejandro_mejias]

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]

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

Regards

Manish

Have you tried one of our suggestions yet?

Again: you cannot use Spaces within an URL.
