Error Code 'Connection Failed' CL_HTTP_CLIENT while calling URL

Former Member — Thu, 14 Aug 2014 01:11:53 GMT

Guys,

I am trying to call a Google API directly from the ABAP code using CL_HTTP_CLIENT. While calling the URL I am getting error message 'Connection Failed', this is Google Geocoding API.

*&---------------------------------------------------------------------*
*& Report YGEOCODE
*&---------------------------------------------------------------------*
REPORT ygeocode.

*Selection-screen
SELECTION-SCREEN BEGIN OF BLOCK b1.
PARAMETERS: lv_input TYPE string DEFAULT 'http://maps.googleapis.com/maps/api/geocode/xml?address=',
             lv_addr TYPE string.
SELECTION-SCREEN END OF BLOCK b1.

CONSTANTS: lv_n       TYPE c     VALUE '&',
            lv_sensor TYPE char7 VALUE 'sensor=',
            lv_false   TYPE char5 VALUE 'false'.

DATA : lv_value TYPE string.
DATA : http_client TYPE REF TO if_http_client .
DATA : lv_url TYPE string.
DATA : return TYPE string.
DATA : lv_err_string TYPE string ,
        lv_ret_code TYPE sy-subrc .

* Build Url
CONCATENATE lv_input lv_addr lv_n lv_sensor lv_false
        into lv_url.
TRANSLATE lv_url TO LOWER CASE.

* Create Client
CALL METHOD cl_http_client=>create_by_url
   EXPORTING
     url    = lv_url
   IMPORTING
     client = http_client.

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

* Receive
CALL METHOD http_client->receive
   EXCEPTIONS
     http_communication_failure = 1
     http_invalid_state         = 2
     http_processing_failed     = 3.
IF sy-subrc NE 0.
   http_client->response->get_status(
     IMPORTING
       code   = lv_ret_code
       reason = lv_err_string
          ).
   MESSAGE lv_err_string TYPE 'I'.
ENDIF.

* Now we have the response , parse , display
* do what you like
return = http_client->response->get_cdata( ).
