在GAE/J上将PDF文件上传到pdfjet生成的Google文档 [英] Uploading a PDF file to Google Docs generated by pdfjet on GAE/J

问题描述

我需要将PDF文件上载到用户google docs，该文件由pdfjet在google app引擎上生成.我想出使用gae/j的pdfjet生成pdf. pdfjet使用流创建pdf.无论如何，有没有将流转换为文件，所以我可以上传给用户谷歌文档.我尝试了gaevfs，但无法正常运行.如果需要，我可以使用其他pdf生成解决方案或其他虚拟文件系统等.

I need to upload a PDF file to users google docs which is generated by pdfjet on google app engine. I figure out to generate pdf using pdfjet for gae/j. pdfjet uses streams to create the pdf. Is there anyway to convert stream to file so I can upload to users google docs. I tried gaevfs but couldn't make it work. I can use another pdf generation solution if needed or another virtual file system etc.

ByteArrayOutputStream os = new ByteArrayOutputStream();
PDF pdf = new PDF(os);

Google Docs API代码

DocumentListEntry newEntry = new PdfEntry();
newEntry.setTitle(new PlainTextConstruct("Some Report"));

我无法执行的行:setFile(File，String)

newEntry.setFile(pdf, "application/pdf");

谢谢.

推荐答案

您难道不能简单地使用ByteArrayOutputStream.writeTo(OutputStream)方法将ByteArrayOutputStream写入FileOutputStream吗?像这样:

Couldn't you simply write from ByteArrayOutputStream to FileOutputStream using the ByteArrayOutputStream.writeTo(OutputStream) method? Like this:

ByteArrayOutputStream os = new ByteArrayOutputStream();
PDF pdf = new PDF(os);  
FileOutputStream fos = new FileOutputStream("myPDF.pdf");
baos.writeTo(os);
