abap 将xstring转换成PDF展示

本文主要是介绍abap 将xstring转换成PDF展示，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

收到外围系统的xstring之后，如何在sap中将其打开呢

1.创建一个屏幕

2.绘制一个customer control

3.创建流逻辑

4.流逻辑如下：

DATA: go_html_container TYPE REF TO cl_gui_custom_container,
go_html_control   TYPE REF TO cl_gui_html_viewer,
lv_url           TYPE char255,
lt_data          TYPE STANDARD TABLE OF x255.MODULE status_0100 OUTPUT.IF go_html_container IS INITIAL .CREATE OBJECT go_html_containerEXPORTINGcontainer_name = 'PDF'.CREATE OBJECT go_html_controlEXPORTINGparent = go_html_container.CALL METHOD go_html_control->load_dataEXPORTINGtype                   = 'application'subtype                = 'pdf'IMPORTINGassigned_url           = lv_urlCHANGINGdata_table             = lt_dataEXCEPTIONSdp_invalid_parameter   = 1dp_error_general       = 2cntl_error             = 3html_syntax_notcorrect = 4OTHERS                 = 5.CALL METHOD go_html_control->show_urlEXPORTINGurl                    = lv_urlin_place               = 'X'EXCEPTIONScntl_error             = 1cnht_error_not_allowed = 2cnht_error_parameter   = 3dp_error_general       = 4OTHERS                 = 5.ENDIF.ENDMODULE.MODULE user_command_0100 INPUT.CALL METHOD go_html_control->freeEXCEPTIONScntl_error        = 1cntl_system_error = 2OTHERS            = 3.LEAVE TO SCREEN 0. "因为我有两个屏幕，所以我要返回上一个，若只有一个，可以注释这句
ENDMODULE.
