Running PHP-File in Background Task??

[ramona_wolf]

Hello!

I need some help. I have a php-filename ( http:
www.site.com\values.php?date=2009-10-21&value=1234 ).

The data (date and value) I get from a SAP table. That means, I concatenate the script name in SAP.

Now I have to run this file (or script?) automatically in SAP (in background).

But I can't find a method to do this.

Kind Regards

Hi,

You may try to use class httpclient as follows:

DATA: http_client TYPE REF TO if_http_client .
DATA: l_url TYPE string , 
      l_result TYPE string ,
      l_str TYPE string .
DATA: lt_results TYPE TABLE OF string. 
 
 CLEAR l_url .
 CONCATENATE 'http:\\www.site.com\values.php?date=' '2009-10-21' '&value=' '1234'
   INTO
  l_url . 
 
 CALL METHOD cl_http_client=>create_by_url
 EXPORTING url = l_url
 IMPORTING client = http_client
 EXCEPTIONS argument_not_found = 1 
   plugin_not_active = 2 
   internal_error = 3 
   OTHERS = 4. 
 
 CALL METHOD http_client->send 
  EXCEPTIONS 
    http_communication_failure = 1
    http_invalid_state = 2. 
 
CALL METHOD http_client->receive
   EXCEPTIONS
 http_communication_failure = 1 
 http_invalid_state = 2
 http_processing_failed = 3.
 
 CLEAR l_result .
 l_result = http_client->response->get_cdata( ). 
 
 REFRESH lt_results .
 
 SPLIT l_result AT cl_abap_char_utilities=>cr_lf INTO TABLE lt_results . 
 
 LOOP AT lt_results INTO l_str.
   WRITE:/ l_str .
 ENDLOOP .

Hello Simo,

running as a background job is the same result as written.

What could be the reason for the error message?

You need to talk to your network people to find out how to get out to the internet

CALL METHOD cl_http_client=>create_by_url
 EXPORTING url = l_url
           proxy_host = proxy.xxx.com ???!!!
           proxy_service = 80 ???!!!
 IMPORTING client = http_client
 EXCEPTIONS argument_not_found = 1 
   plugin_not_active = 2 
   internal_error = 3 
   OTHERS = 4.

Hi Simo,

We made progress in solving the problem.

Now I get the error

HTTP message has an invalid format. Contact your system administrator

I searched for that error, but I couldn't find a solution for it.

Can you help me again, please?

Thanks very much for your help.

Kind Regards

Ramona

The method calls all did return with code 0:

CALL METHOD cl_http_client=>create_by_url, sy-subrc = 0

CALL METHOD cl_http_client->send, sy-subrc = 0

CALL METHOD cl_http_client->receive, sy-subrc = 0

Insert code below before CALL METHOD http_client->send

DATA: form_data type tihttpnvp.
DATA: line type ihttpnvp.

call method http_client->request->set_header_field
  EXPORTING
    name  = '~request_method'
    value = 'POST'.

line-name = 'date'.
line-value = '2009-10-21'.
APPEND line to form_data.

line-name = 'value'.
line-value = '1234'.
APPEND line to form_data.

call method http_client->request->set_form_fields
  EXPORTING
    fields = form_data.

Hello Simo,

now I get the following error:

WRITE: / sy-datum, ': ', / l_url.

LOOP AT lt_results INTO l_str.

WRITE:/ l_str .

ENDLOOP .

How you can see, I tried several ways to run.

I can't find a solution.

I tried with l_url is the full path name and I tried it without the data.

What do I wrong?

thanks for your help!

I quess HTTP request still does not contain all the header fields needed.

Add the fields below and learn more from http://php.net/manual/en/reserved.variables.server.php

call method http_client->request->request->set_header_field
  exporting  name = '~request_uri'
	     value = '/path/values.php' .

call method http_client->request->request->set_header_field 
  exporting name = '~request_method'
           value = 'POST'.

call method http_client->request->request->set_header_field
  exporting name = '~enctype'
	    value = 'multipart/form-data'.

call method http_client->request->request->set_header_field
 exporting name = 'Content-Type'
           value = 'text/plain'.

call method http_client->request->request->set_header_field
 exporting name = '~server_protocol'
           value = 'HTTP/1.1'.

call method http_client->request->request->set_header_field
 exporting name = '~Content-Length'
           value = '60000' .

Hello Simo,

when running:

CALL METHOD cl_http_client=>create_by_url
    EXPORTING
      url                = l_url
      proxy_host         = '172.xxx'
      proxy_service      = '8080'

I get the error: HTTP message has an invalid format. Contact your system administrator.

When running

CALL METHOD cl_http_client=>create_by_url
    EXPORTING
      url                = l_url

I get the error: 404 Resource not found. Partner not reached.

Could it be a missing authority?

Could you please check my source code? Perhaps I've done anything wrong.

Thank you very much!

Add host and proper path if you got error Message: Badly formed request - No path or hostname in request.

* replace site.com with your site (http:\\www.site.com -> site.com)
call method http_client->request->set_header_field 
 exporting name = 'HOST' 
           value = 'site.com:8080'.

* replace 'path' with a proper path or just /values.php
call method http_client->request->request->set_header_field
  exporting  name = '~request_uri'
	     value = '/path/values.php' .
 

Try to get the http trace from your php server to find out all the header fields the site expects.

example:

HEAD / HTTP/1.1

Host: google.com

User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; MS-RTC LM 8; InfoPath.2)

Dear Simo,

it's almost finished. There is no error message any more, but the website is not updated.

I'll try to find out the parameter which has to be set, but can you help me one more time?

Hi,

Have you forgot this:

 CALL METHOD http_client->send 
  EXCEPTIONS 
    http_communication_failure = 1
    http_invalid_state = 2.

It should be before CALL METHOD http_client->receive

Also add the following to see the results at the end:

 REFRESH lt_results .
 
 SPLIT l_result AT cl_abap_char_utilities=>cr_lf INTO TABLE lt_results . 
 
 LOOP AT lt_results INTO l_str.
   WRITE:/ l_str .
 ENDLOOP .

Hi!

Both codes you sent are in my program, I deleted it in the message by an oversight.
