p:带有PDF文件的媒体会导致“文件不是以'％PDF-'开头". IE7中的错误 [英] p:media with PDF file causes "File does not begin with '%PDF-'." error in IE7
问题描述
我正在根据以下问题使用<p:media>:如何使用< p:media>绑定动态内容?
I'm using <p:media> based on this question&answer: How to bind dynamic content using <p:media>?
在IE7中无法正常运行，但Mozilla和Chrome可以正常运行. IE7错误如下:
It doesn't work in IE7 while it works fine Mozilla and Chrome. IE7 errors as:
文件不是以'％PDF-'开头.
File does not begin with '%PDF-'.
我了解这是因为生成的PDF的文件名为dynamiccontent.properties.xhtml.如何更改文件名?我尝试在DefaultStreamedContent构造函数中传递文件名，但是没有效果.
I understood it's because the file name for generated PDF is dynamiccontent.properties.xhtml. How do I change the file name? I tried passing the file name in DefaultStreamedContent constructor, but it had no effect.
推荐答案
很抱歉，您可以死贴，但对于那些正在阅读本文的人来说，是的，这可能是文件名问题.
Sorry to necro-post but for those who are seeing this article, yes it can be a file name issue.
Acrobat产品从历史上就一直打开PDF，只要％PDF-header开始在文件的前1024个字节之内即可. ％PDF-header之前没有对多余字节进行检查.但是，10.1.5和11.0.01更新通过强制执行更严格的PDF标头解析来提高安全性.现在，该产品拒绝打开一小部分未正确以'％PDF-'标头开头的PDF.
Acrobat products have historically opened a PDF as long as the %PDF-header started anywhere within the first 1024 bytes of the file. No checks were performed on the extraneous bytes before the %PDF-header. However, the 10.1.5 and 11.0.01 updates improve security by enforcing stricter parsing of the PDF-header. The product now refuses to open the small fraction of PDFs that do not correctly start with the '%PDF-' header.
您可以通过设置适当的首选项来禁用计算机上的标头验证
You can disable the header validation on machines by setting the appropriate preference
如果AVGeneral密钥不存在，请手动创建.
If the AVGeneral key does not exist, create it manually.
HKLM路径一般为:
The HKLM path is generically:
HKLM \ Software \ Adobe(产品名称)(版本)\ AVGeneral \ bValidateBytesBeforeHeader = dword:00000000
HKLM\Software\Adobe(product name)(version)\AVGeneral\bValidateBytesBeforeHeader=dword:00000000
例如，要更改Acrobat 11.0的行为，请在以下位置创建DWORD:HKLM \ SOFTWARE \ Adobe \ Adobe Acrobat \ 11.0 \ AVGeneral \ bValidateBytesBeforeHeader = dword:00000000
For example, to change the behavior for Acrobat 11.0, create a DWORD at this location: HKLM\SOFTWARE\Adobe\Adobe Acrobat\11.0\AVGeneral\bValidateBytesBeforeHeader=dword:00000000
HKCU路径一般为:
The HKCU path is generically:
HKCU \ Software \ Adobe(产品名称)(版本)\ AVGeneral \ bValidateBytesBeforeHeader = dword:00000000
HKCU\Software\Adobe(product name)(version)\AVGeneral\bValidateBytesBeforeHeader=dword:00000000
例如，要更改Reader 10.0的行为，请在以下位置创建DWORD:HKCU \ SOFTWARE \ Adobe \ Acrobat Reader \ 10.0 \ AVGeneral \ bValidateBytesBeforeHeader = dword:00000000
For example, to change the behavior for Reader 10.0, create a DWORD at this location: HKCU\SOFTWARE\Adobe\Acrobat Reader\10.0\AVGeneral\bValidateBytesBeforeHeader=dword:00000000
始终在首选项路径中更改产品和版本号以匹配您的安装.这种方法使PDF可以显示在您控制的机器上.
Always change the product and version number in the preference path to match your installation. This method allows the PDF to display on machines you control.
