ColdFusion CFPDFFORM不会填充PDF表单字段

Question

我创建了一个带有两个表单字段的快速PDF文件,名字和姓氏(或FirstName和LastName),带有"提交"按钮,并使用以下代码尝试在新的PDF文件中填充这些字段:

<cfpdfform action="populate" source="#variables.AbsPath#\test.pdf">
    <cfpdfformparam name="FirstName" value="foo" />
    <cfpdfformparam name="LastName" value="bar" />
</cfpdfform>

但是,我收到此错误:

The system has attempted to use an undefined value, which usually indicates a programming error, either in your code or some system code.
Null Pointers are another name for undefined values.
Platform, Locale, and Platform Name must not be null

我尝试阅读PDF文件,以确保使用此表单字段是正确的,它们是:

<cfpdfform action="read" source="#variables.AbsPath#\test.pdf" result="fields" />

<cfdump var="#fields#">

结构转出:

FirstName:  [empty string]
LastName:   [empty string]
Submit:     [empty string]

我尝试搜索Adobe文档和其他一些网站,但无法找到此错误的解决方案.我还尝试在cfpdfform标记中添加"destination"参数以备不时之需,但结果相同.PDF文件确实存在.有任何想法吗？提前致谢.

更新:这是堆栈跟踪:

Answer 1

我相信这是使用特定服务器的字体问题.这就是为什么相同的代码将在生产服务器而不是测试服务器上工作的原因.我遇到了同样的问题,虽然我没有一个很好的解决方案,但这是我所学到的.

1. 堆栈跟踪显示获取OpenType字体的getPlatformFontDescription时出错.
2. 我们的Windows服务器将一些TrueType字体列为OpenType.是你的？

3. 使用以下代码更正了问题,但这只是一个解决方法.

   <cfpdf name="local.pdffile" action="read" source="some path" >
   <cfscript>
   local.pdfReader = createObject("java", "com.lowagie.text.pdf.PdfReader").init(tobinary(local.pdffile));
   local.outputStream = createObject("java", "java.io.ByteArrayOutputStream").init();
   local.pdfStamper = createObject("java", "com.lowagie.text.pdf.PdfStamper").init(local.pdfReader,local.outputStream);
   local.Acroform = local.pdfStamper.getAcroFields();
   //Populating Form Fields     
    local.Acroform.setField("Field1",Arguments.Value1);
    local.Acroform.setField("Field2",Arguments.Value2);
    // etc.
    local.pdfStamper.setFormFlattening(true); //optional
     local.pdfStamper.close();
     local.pdfReader.close();
     local.pdffile = local.outputStream.toByteArray();
    </cfscript>
    <!--- flatten="no" must be set or you will get the error again  --->
    <cfpdf action="write" source="local.pdffile" destination="#variables.OutputPath##local.UUID#.pdf" overwrite="yes" flatten="no"  />
   

4. 更多诊断:仅使用Java子系统列出服务器可用的所有字体也会失败.试试这个.

    <cfset list=createobject("java","com.adobe.internal.pdfm.util.FontSetBuilder")>
    <cfdump var="#list#">
    <cfset dummy = list.getPdfFontSet()>
    <cfdump var="#dummy.toString()#">
    <!--- this should fail --->
   

5. 我们通过从Windows\Fonts文件夹中删除所有字体并隔离损坏的字体来"修复"我们的问题.这是艰苦的,但似乎工作.

祝好运!
