SAP发布HTTP接口

1、创建类

 引用标准接口

改写集成的接口方法

 此处仅实现POST方法，将传入的JSON报文转为函数传入参数，调用获取物料接口，并将返回的物料信息，转换为JSON报文返回

  METHOD if_http_extension~handle_request.

    DATA:lv_method   TYPE string,
         lv_req_json TYPE string,
         lv_res_json TYPE string.
    lv_method = server->request->get_header_field( '~request_method' ).
*    lv_path = server->request->get_header_field( '~request_uri' ).

    IF lv_method <> 'POST'.
      server->response->set_header_field( name = 'Content-Type'  value = 'text/html' ).
      server->response->set_cdata( '请使用POST方法' ).
      server->response->set_status( code   = 200
                                    reason = '' ).
      RETURN.
    ENDIF.

    TYPES:BEGIN OF ty_input,
            i_matnr TYPE marc-matnr,
          END OF  ty_input.

    DATA:ls_input TYPE ty_input,
         lt_marc  TYPE TABLE OF ymms_marc.
    TYPES:BEGIN OF ty_output,
            t_marc LIKE lt_marc,
          END OF ty_output.

    DATA:ls_output TYPE ty_output.

    lv_req_json = server->request->get_cdata( ).
    /ui2/cl_json=>deserialize( EXPORTING json = lv_req_json
                                      pretty_name = /ui2/cl_json=>pretty_mode-camel_case
                            CHANGING data = ls_input ).

    CALL FUNCTION 'YLCCTEST01_GETMATNR'
      EXPORTING
        i_matnr = ls_input-i_matnr
      TABLES
        t_marc  = lt_marc.

    ls_output-t_marc = lt_marc.

    lv_res_json = /ui2/cl_json=>serialize( data = ls_output )."pretty_name = /ui2/cl_json=>pretty_mode-low_case ).

    server->response->set_status( code   = 200 reason = 'successfully' ).        "
    server->response->set_header_field( name = 'Content-Type'  value = 'application/json' ).
    server->response->set_cdata( lv_res_json  ).
  ENDMETHOD.

2、创建WEB服务

事务代码SICF，创建新节点

 处理器清单中填上类名称

 3、激活并测试服务
