在 Web 应用程序中显示 PDF [英] Display PDF in Web Application
问题描述
我用谷歌搜索了这个，搜索了这个，浏览了 SO 和其他网站(我已经尝试阅读这个问题几个小时了)，但我似乎仍然无法找到一个令人满意的解决方案一个简单、常见的编程问题.
I have googled this, searched this, looked through SO and other sites (I've been trying to read on this issue for hours now), but I still can't seem to find a satisfactory solution to what seems to be a simple, common programming issue.
让我来设置场景:
- 我有一个网站/网络应用程序，允许用户搜索 SQL Server 库.
- 与搜索结果相关的大部分文档都是 PDF 文件.
- PDF 文件以 BLOB 的形式存储在 SQL Server 数据库中.
- 我希望能够从数据库中动态提取 PDF 并将其显示给用户.
- 为了保留用户的搜索进度，我想我想在另一个浏览器窗口/标签中打开文件
- 我已经知道如何将 PDF 保存到服务器的指定目录中.
- 我不想希望用户看到文件的路径.
- 在合理范围内，我想要一个适用于所有主要浏览器的解决方案:
- I've got a website/web application that allows the user to search a SQL Server library.
- Most of the documents related to the search results are PDF files.
- The PDF files are stored inside of the SQL Server database a BLOBs.
- I want to be able to dynamically pull a PDF from the database and display it to the user.
- In order to preserve the user's search progress, I think I'd like to open the file in another browser window/tab
- I've figured out how to save the PDF to the server in a specified directory.
- I DON'T want the user to see the path to the file.
- Within reason, I want a solution that works in all major browsers:
- Internet Explorer
- 火狐
- 铬
- Safari(包括 iPhone/iPad Mobile Safari)
到目前为止，我尝试过的每个解决方案都存在一些基本问题:
Every solution I've tried so far has some basic problems wrong with it:
- 在 iPhone/iPad 上使用 iFrames 似乎失败了
- 使用 Server.Transfer(我使用的是 ASP.NET)显示乱码而不是 PDF
- 我尝试了几个演示 3rd 方解决方案，但它们也很糟糕！
我想不通！我真的是一名桌面开发人员，这在 Windows 中EASY！为什么网络这么难?
I can't figure it out! I'm really a desktop developer, and this was EASY in Windows! Why is it so hard with the web?
是我笨吗，这真的是一个简单的练习，还是这个基本任务真的那么难?
Am I stupid and this is really an easy exercise, or is this basic task really that hard?
请帮我指明正确的方向！
Please help point me in the right direction!
谢谢！！！

您可以通过为链接指定 target="_blank" 来在新选项卡中打开 pdf.博客中提到的 ByteArray 是您从 DB 中提取的 BLOB.希望这会有所帮助.
You can have pdf opened in a new tab by speccifying target="_blank" for the link. ByteArray mentioned in the blog is your BLOB from the DB. Hope this helps.
