在iframe中显示本地htm文件？ [英] Displaying local htm file in iframe?

问题描述

我使用htm格式的MailBee.NET对象在本地机器上保存了一些电子邮件。为每个电子邮件创建一个单独的文件夹，例如在服务器上使用电子邮件messageID

D：\Emails\GmailId1380ec660e0e656a\doc.htm

是从Gmail下载的电子邮件。我也在数据库中保存上述路径，以便稍后使用。现在我试图在iframe中显示这个htm文件，但它不起作用。用户点击电子邮件，将他带到read_email页面，我试图将上述路径分配给iframe，但iframe保持空白。

  emailMessage.Attributes.Add（ SRC，commandReader [ email_message_path]的ToString（））; 
  

emailMessage是iframe的名称，commandReader是普通的SqlDataReader，我正在使用它来读取上面提到的文件，然后将该路径分配给iframe的src属性，我已将该代码放入page_load事件中。

但正如我所说Iframe保持空白。请帮助我。

谢谢。

解决方案

本地文件引用文件 URI方案。如果您的电子邮件路径仅为 D：\Emails\ ... ，那么您必须在 file：// ：

  file：// D：\Emails\ ... 
  

请注意，大多数浏览器都会阻止您在远程网站中包含本地文件 ！。

I am saving some emails on my local machine using MailBee.NET Objects in htm format. A separate folder is created for each email using email messageID on server for example

D:\Emails\GmailId1380ec660e0e656a\doc.htm

is an email downloaded from gmail. I am saving also the above mentioned path in database so I can use it later. Now I am trying to display this htm file in an iframe but it is not working. A user clicks on email which takes him to the read_email page on which I am trying to assign the path mentioned above to an iframe but the iframe remains blank.

emailMessage.Attributes.Add("src",commandReader["email_message_path"].ToString());

emailMessage is the name of iframe and commandReader is normal SqlDataReader which I am using to read the path of the file mentioned above and then assigning that path to src attribute of iframe, I have placed this code in page_load event.

But as I said Iframe remains blank. Please help me out.

Thanks.

解决方案

Local files are referenced with the file URI scheme. If your email message path is only D:\Emails\... then you'll have to prepend it with file:// :

file://D:\Emails\...

Note that most browser will prevent you from including a local file from a remote website !.
