URGENT ISSUE -

Hi averyone

I need to make an upload of a file via POST method to a web service.

I have no problems passing the parameters user and password in the header line but i cant add multipart data to post de txt file .

the code im using is :

*create client object

CALL METHOD cl_http_client=>create

EXPORTING

host = host

service = port

scheme = scheme

IMPORTING

client = client.

*Set Header

client->request->set_header_field( name = '~request_uri'

value = path ).

client->request->set_header_field( name = '~request_method'

value = 'POST' ).

client->request->set_header_field( name = '~enctype'

value = 'multipart/form-data' ).

client->request->set_header_field( name = 'Content-Type'

value = 'text/plain').

client->request->set_header_field( name = '~server_protocol'

value = 'HTTP/1.1' ).

Set de los parametros a enviar

client->request->set_form_field( name = 'user'

value = '20295635089').

client->request->set_form_field( name = 'password'

value = '010107').

client->request->set_form_field( name = 'file'

value = 'c:\TB_20295635089_002002_20061212_000001.txt').

DATA: lv_fields TYPE tihttpnvp.

CALL METHOD client->request->get_header_fields

CHANGING

fields = lv_fields.

send and receive

client->send( ).

CALL METHOD client->receive

EXCEPTIONS

http_communication_failure = 1

http_invalid_state = 2

http_processing_failed = 3

OTHERS = 4.

Im getting the following error message

<HTML><TITLE>411 Invalid value for Content-Length header</TITLE><BODY><h1>411 Invalid value for Content-Length header</h1></BODY></HTML>

client->request->set_form_field( name = 'file'

value = 'c:\TB_20295635089_002002_20061212_000001.txt').

the above line is the problem.

you have to use gui_upload to upload the data first and then set it to the request object

request->set_cdata

then

request->send

Sorry but i cant take this line out .

File is one of de obligatories parameters ..

if i upload de data and set it to the request object and take out the set_form_file = name = 'file' i get the error : parameter missing FILE .

thanks anyway .. hope you can help me with this.

Regards

i am checking, will get back. however i feel that this may not be possible as the input type ="file" is very strict, you cannot even default file name to this element in normal html programming.

Hi Raja,

I know this is a very old thread but I have the same problem. I need to send a parameter using set_form_field, because If I put it inside a multipart , the web site doesn't recognize it, but using method set_form_field, I don't know what value to pass, because the parameter is type file.

Do you know if there is a way to send a parameter type file , with set_form_field method?

Thansk,

Take the C:\ from that line and then use append_cdata and send.

Dear all, we are facing same issue, we are not able to send requested file as txt output format.

We sent user & password and input file as string. This is correct? Could you please send us an example?

Thanks in advance,

I found a way to make it work, please remove the username and password ARBA service you put: P

Dear Maxi,

could you please tell us how you send the username and password to ARBA? These are mandatory fields for HTTP Post conection.

Thanks in advance,

Daniela.
