用ABAP进行HTTP编程如何获取交互中的错误明细

最精简的写法是这样写的：

可以enhance成下面的样子，这样一旦出错我们能够知道准确的error message。

   CALL METHOD l_http_client->receive                                  
      EXCEPTIONS                                                        
        http_communication_failure = 1                                  
        http_invalid_state         = 2                                  
        http_processing_failed     = 3                                  
        OTHERS                     = 4.                                 
    IF sy-subrc <> 0.                                                   
      l_sysubrc = sy-subrc.                                             
      CALL METHOD l_http_client->get_last_error                         
        IMPORTING                                                       
          code    = l_sysubrc                                           
          message = l_error_text.                                       
    ENDIF.                                                              
                                                                        
    CALL METHOD l_http_client->response->get_status                     
      IMPORTING                                                         
        code   = l_status                                               
        reason = l_reason.     

比如下图这个例子，errorcode 407， message ICM_HTTP_SSL_ERROR，按照SAP官方文档的说法，是certificate import出了问题。
