cl_http_client usage causing Web UI timeout

510 Views

Hello,

I'm currently running into an issue when triggering a mobile notification (via HTTP post) from Web UI and was wondering if anyone had any experience doing this or thoughts on my issue.

I have it set up to trigger the mobile notification when saving a service request. The notification itself works great and reaches our mobile devices, but afterwards the next action performed in Web UI results in a 500 timeout.

I've determined the issue is caused whenever I close the HTTP connection I opened to send out the notification. If I remove the code which closes the connection, then there is no timeout issue. However, I didn't want to just open the connection then not close it so I wanted to see if anyone knew why it would be timing out.

Here are the relevant portions from my code:

DATA:

lr_client TYPE REF TO if_http_client.

* Create URL

cl_http_client=>create_by_url( EXPORTING url = lv_device_url

IMPORTING client = lr_client

EXCEPTIONS

argument_not_found = 1

plugin_not_active = 2

internal_error = 3

OTHERS = 4 ).

lr_client->request->set_method( 'POST' ).

* Content Type

lr_client->request->set_header_field( EXPORTING name = 'Content-Type'

value = 'application/xml' ).

* Authentication

lr_client->request->set_header_field( EXPORTING name = 'Authorization'

value = lv_auth ).

* Message to User

lr_client->request->set_header_field( EXPORTING name = 'X-SMP-APNS-ALERT'

value = lv_notif ).

* Alert Sound

lr_client->request->set_header_field( EXPORTING name = 'X-SMP-APNS-SOUND'

value = 'Default' ).

* Send Request

lr_client->send( EXCEPTIONS http_communication_failure = 1 http_invalid_state = 2 ).

CALL METHOD lr_client->receive(

EXCEPTIONS

http_communication_failure = 1

http_invalid_state = 2

http_processing_failed = 3 ).

lr_client->close( ).

Any thoughts on this issue would be appreciated. Thank you.
