I want to load my pdf file in a web page. The user should not have the provison to save or print the file. the below code opens the pdf file as attachment, but i want to open it directly in the page.
另请提供可以禁用 pdf 菜单栏的任何 Javascript 。
Response.ContentType = "Application/pdf";
Response.AppendHeader("content-disposition", "attachment; filename=" + old_filename + ".pdf");
Response.TransmitFile(Server.MapPath("~/pdf_files/" + old_filename));
Response.End();
我想在网页上加载我的 pdf 文件。 用户不应该有保存或打印文件的附带条件 。
所以,您希望用户能够将 PDF 本地化( 这意味着文件本身必须可传输到本地计算机), 但是您不想让用户能够保存到本地吗? 不, 您不能这样做 。 您要么阻止信息离开您的机器, 要么您不这样做 。
您可以在服务器上将 PDF 转换成图像( 当然他们可以下载)- 但如果您向客户端提供 PDF 本身, 保存它总是微不足道的 。
不可能。 您可以使用 java 脚本功能在您的网页上停止右键点击( 然后用户不会通过右键点击 pdf/ image 获得保存菜单), 但是他们仍然可以在键盘上键入 ctrl+s 来保存页面 。
如果您想要删除保存功能, 您可以使用 iframe 显示您的 pdf 文件 。
另外,在您 pdf 链接的末尾加上“#toolbar=0”,用于 src 参数。
