2.HTML Viewer
通过cl_gui_html_viewer类显示url链接或者显示HTML页面。
1.创建cl_gui_html_viewer类对象，调用show_url显示url对应网页；
2.调用load_html_document方法加载Tcode:SMW0的html；
上传html文檔：
<HTML> <HEAD> <TITLE>SAP HTML Page</TITLE> </HEAD> <BODY> <H1> <IMG SRC=SAPLOGO.GIF ALIGN=MIDDLE> SAP HTML Header </H1> <P> <H2>SAP HTML Post Form</H2> <FORM method=post action=SAPEVENT:POST> <INPUT TYPE=text NAME=FirstName VALUE=John> <INPUT TYPE=submit VALUE="Submit input using POST method"> </FORM> </P> <P> <H2>SAP HTML Get Form</H2> <FORM method=get action="SAPEVENT:GET"> <INPUT TYPE=text NAME=FirstName VALUE=king> <INPUT TYPE=submit VALUE="Submit input using GET method"> </FORM> </P> </BODY> </HTML>
Tcode:SMW0,上传html文件
