HTTP_POST Function

Hello All,
I am trying to use the HTTP_POST function to send a table to a outside source. Can someone tell my what parameters I have to have filled and with what before I can call the function succesfully. Thanks.
Gabriel

Could you please post the error here so ppl can help you.
Also if this error is unavoidable then you can handle it in method itself...
Regards,
BJ

Using Function module HTTP_POST with SSL anonymous

Does anybody know how I can use the function module HTTP_POST called from ABAP but to use SSL communication using the anonymous client.
I think by default it uses the DEFAULT standard client for communication.
Is there anyway that the HTTP_POST function module can use a type 'G' connection in SM59.
I have tried to use the newer cl_http_client but for some reason the server I'm connecting to does not like the HTTP_POST that is sent via this mechanism. The only difference I can see is that the header fields i set using cl_http_client come out in lowercase.
content-type: application/x-www-form-urlencoded; charset="UTF-8"
content-length: 288
Whereas using HTTP_POST I can define the header fields exactly how they should be displayed e.g.
Content-type: application/x-www-form-urlencoded; charset="UTF-8"
Content-length: 288
Does anybody know how to rectify this
thanks,

Hi Agasti,
Use class CL_HTTP_CLIENT. there is a method SET_HEADER_FIELD , u can use POST in that.
It will be something like below:
data: client type ref to if_http_client.
ur code to call the webservice API (method CREATE or CREATE_BY_URL
CALL METHOD client->request->set_header_field
EXPORTING
name = '~request_method'
value = 'POST'.
It will work.
cheers,
Hema.

HTTP_POST to .aspx URL/form

Hi Folks,
My requirement is to post data to an aspx form from ABAP program. After searching in the forums, I decided to use HTTP_POST function module to achieve the goal.
Now when I execute my program, I do get the status as 'OK' and status code of '200' but data is not getting posted to the form. The way I have been trying to pass data is - I have a structure with field names same as the form field names. I populate the corresponding values in the local work area and append it to request_body table. Which I have come to realize may not be the correct way. I also tried passing the data same way to request header, that did not work either.
Does someone have example code on how to use HTTP_POST? or suggestions? I tried where-used on the FM, but could not find anything discreet.
Or at a higher level, is this approach right to post data?
Thanks!

Thanks Aarif!
I did come across this post. I can reach the HTTP service. Trying to make the parameters values work. But still not able to.

Portal application can't read request info

hi all,
i use portal application for change portal user's infos.but when i sent request info,
request.getServletRequest().getInputStream() method is cutting my sending line after 90. character.
in R3 side i use HTTP_POST function and fill request info (table paramater).
i tried to send 2 line(less than 90 character) in request info, but i can't read second line in java code.
Is IPortalComponentRequest accept only 90 character ?
how can i solve this problem , any idea ?
my code is below, variable "str" is filling only first 90 character;
     protected void doOnNodeReady(
               IPortalComponentRequest request,
               IEvent event) {
     String str = "";
     try {
          InputStream is = request.getServletRequest().getInputStream();
          InputStreamReader isr = new InputStreamReader(is);
          int c;
          while ((c = isr.read()) > -1) {
          str = str + (char) c;
            } catch (java.io.IOException ex) {
             str = "Error accessing input stream";

New discovery...If I shut down all instances of IE on my machine, then reopen my test form, it works. Once. The second time I try it I get the same peculiar behavior again, until I again shut down all instances of IE.

Calling Portal Application Components

Due to formatting restrictions w/in Portal Application building, I need to be able to create (for example) a report where all headings are blank.
I'd like to then embed the invocation of the report from a Dynamic Page, where the page will contain all of the formatting for the column headings.
I've tried embedding the call two ways:
1) <ORACLE>call RPT_0717092052.show()</ORACLE>
2) <ORACLE>CALL PORTAL30.RPT_0717092052.show (
p_arg_names => PORTAL30.wwv_standard_util.string_to_table2('_show_header:_max_rows:_portal_max_rows'),
p_arg_values => PORTAL30.wwv_standard_util.string_to_table2('YES:25:25'))</ORACLE>
Neither seems to work.
Anyone have any ideas how to make this work??

<i>What I want is to call portal application on background (not to call browser).</i>
you can use CL_HTTP_CLIENT class or HTTP_GET or HTTP_POST function modules for the same. (but you need to pass the user id /pwd in the program) (ITS doesnt fit your case)
check out the demo programs.
for CL_HTTP_CLIENT

Need example of BlackBerry "browser push" in ABAP (ERP)

I'm looking to perform a "browser channel push" from ERP to the BlackBerry BES/MDS. I have all the ABAP completed for the HTML content itself, but I'm struggling with the HTTP message to the MDS. Anyone have an example I can work off of? I'll take either a HTTP_POST function module exmaple, or a HTTP_REQUEST method example.
Thanks

Jay, what is your exact requirement? Is the Java application external to your Tomcat (Turnkey), acting as a separate application? If so, then yes, JMS is the only way you can "subscribe" to a destination in BlazeDS. However, I have a feeling that you are looking for a way to control the subscription to a destination yourself within BlazeDS?

Hi,
Check if any proxy is maitained in the client by going into transaction
SICF-> Goto-> HTTP Client Proxy -> HTTP LOG TAB.
If there is anything maintained under Host name and port, if yes you need to specify the IP address while calling FM HTTP_POST
under PROXY as
192.168.0.1:8080 where first part is IP address & 2nd part(8080) is port.
Also test connection for SAPHTTPA under SM59 to see if its properly configured.

Amit

How to send an XML file via HTTP_POST

I have an ABAP program that creates an XML file and I need to somehow post this XML file to a webserver and read the HTTP Response that it sends back. I see that there is a function module called HTTP_POST but I've never used it before. I also see that there are a number of ABAP Objects related to HTTP. Has anyone done this before.
I'm on SAP 4.7 (6.20)
Thank you,

I went to www.fedex.com and exported their SSL cert. I then imported it into SAP via STRUST. However, I still get the same http_communication_error. The XML needs to be posted to this address: 'https://gatewaybeta.fedex.com:443/GatewayDC'

Using UTL_HTTP.GET_RESPONSE function (PL/SQL)

Hello,
I have a problem using the UTL_HTTP.GET_RESPONSE (URL, 'POST') function while I try to call a function that returns an XML;
The function returning my XML is:
FUNCTION MyFunction return XMLTYPE is
begin
return XMLTYPE('<PROVA>test</PROVA>');
end MyFunction;
To perform the http call I use this function:
FUNCTION POST(URL VARCHAR2, DATA_IN CLOB) RETURN CLOB IS
BEGIN
DECLARE
DATA_OUT CLOB;
PIECE VARCHAR2(4000);
AMT PLS_INTEGER := 4000;
POS PLS_INTEGER := 1;
HTTP_REQ UTL_HTTP.REQ;
HTTP_RESP UTL_HTTP.RESP;
BEGIN
HTTP_REQ := UTL_HTTP.BEGIN_REQUEST (URL, 'POST');
UTL_HTTP.SET_HEADER(HTTP_REQ, 'content-length', LENGTH(DATA_IN));
LOOP
DBMS_LOB.READ(DATA_IN,AMT,POS,PIECE);
UTL_HTTP.WRITE_TEXT(HTTP_REQ, PIECE);
EXIT WHEN AMT < 4000;
POS := POS + AMT;
AMT := 4000;
END LOOP;
HTTP_RESP := UTL_HTTP.GET_RESPONSE (HTTP_REQ);
BEGIN
LOOP
UTL_HTTP.READ_TEXT(HTTP_RESP, PIECE);
DATA_OUT := DATA_OUT || PIECE;
END LOOP;
EXCEPTION WHEN UTL_HTTP.END_OF_BODY THEN NULL;
END;
UTL_HTTP.END_RESPONSE (HTTP_RESP);
RETURN DATA_OUT;
END;
END;
The script pl/sql that calls the preceding function is:
declare
v_resp CLOB;
v_url VARCHAR2(4000);
begin
v_url := 'http:// ... /meters.export_table.MyFunction'
v_resp := POST(v_url, '-');
end;
After this call to my url, the variabile v_resp contains the following error message:
"<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<HTML><HEAD>
<TITLE>400 Bad Request</TITLE>
</HEAD><BODY>
<H1>Bad Request</H1>

Do you know how I can get my XML? What is the problem in that call http for my function?
Thanks

How to pass parameter in   HTTP_POST or HTTP Class

I want to use HTTP_POST to pass xml info by http_post. I want to pass a simple parameter and receive it in a JSP first for test. I assign the value in the following way:
TYPES: BEGIN OF text,
         line(256),
       END OF text.
DATA xml TYPE TABLE OF text WITH HEADER LINE.
xml-line = 'apple=aaa'.
APPEND xml.
and then ...
CALL FUNCTION 'HTTP_POST'
    TABLES
      REQUEST_ENTITY_BODY         = xml
      response_entity_body        = response
      response_headers            = response_headers.
then I use a JSP to receive the parameter, but what I get from "apple" is null.
<br>Param APPLE
     <%
     String apple=request.getParameter("apple");
     out.println(apple);
     %>
QUESTION:
1 Is this way correct for passing a parameter via a HTTP? It seems I failed to pass a parameter.What is the correct way?
2 If I want to pass a whole xml string, what format should I organize my data stream?Maybe I should use cl_http_client to make it?

Post a File to a web server using HTTP_POST

Hello,
I have to generate a program to post a file ".TXT" to a web server using a HTTP POST with multipart form and a couple of variables (user, password).
I was investigating and I found that I can do it using SAPHTTP but I dont know how to work with the FM HTTP_POST.
Does anyone have a sample code?
Thanks
Ariel

sample usage:
CALL FUNCTION 'HTTP_POST'
    EXPORTING
      ABSOLUTE_URI                = IM_OFX_CONTROL_DATA-ADDRESS
      REQUEST_ENTITY_BODY_LENGTH = RESPONSE_ENTITY_BODY_LENGTH

      USER                        = IM_OFX_CONTROL_DATA-HTTP_USER
      PASSWORD                    = IM_OFX_CONTROL_DATA-HTTP_PASSWORD
      BLANKSTOCRLF                = 'X'
    IMPORTING
      STATUS_CODE                 = STATUS
      STATUS_TEXT                 = STATUS_TEXT
      RESPONSE_ENTITY_BODY_LENGTH = RLENGTH

   EXCEPTIONS
        OTHERS                      = 1.
Refer the programs:
