PDFKit 未生成正确的 PDF

我安装了 PDFKit 和 wkhtmltopdf。

在一个操作中，我渲染了一个简单的 html，如下所示：

<html><body><h1>Hello Internet!</h1></body></html>

当我使用 .pdf 扩展名运行操作时，它会生成错误的 pdf 文件。调试 PDFKit 我得到了这些行：

result = IO.popen(invoke, "w+") do |pdf|
  pdf.puts(@source.to_s) if @source.html?
  pdf.close_write
  pdf.gets(nil)
end

嗯，这是生成我的 PDF 的地方，它使用命令行 no wkhtmltopdf 和我的 html 作为输入。

使用 rdebug 我发现 invoke 的值是：

"c:\Program Files\wkhtmltopdf\wkhtmltopdf.exe" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-"

并且 @source.to_s 是

<html><body><h1>Hello Internet!</h1></body></html>

好的，所以我尝试像这样手动运行命令：

"c:\Program Files\wkhtmltopdf\wkhtmltopdf.exe" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-" < c:\hello_internet.html > correct.pdf

显然在 hello_internet 中有 @source.to_s 的内容

运行它会产生正确的 pdf正在生成。

生成的正确 pdf 位于此处，错误的是此处。

我不知道这里出了什么问题。

谢谢。

原文

I installed PDFKit and wkhtmltopdf.

In one action I render a simple html like:

<html><body><h1>Hello Internet!</h1></body></html>

When I run my action with .pdf extension it generates a wrong pdf file. Debugging PDFKit I got to these lines:

result = IO.popen(invoke, "w+") do |pdf|
  pdf.puts(@source.to_s) if @source.html?
  pdf.close_write
  pdf.gets(nil)
end

Well, this is where my PDF is generated, it uses a command line no wkhtmltopdf and my html as input.

Using rdebug I found that the value for invoke is:

"c:\Program Files\wkhtmltopdf\wkhtmltopdf.exe" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-"

And @source.to_s is

<html><body><h1>Hello Internet!</h1></body></html>

Ok, so I tried to run the command by hand like this:

"c:\Program Files\wkhtmltopdf\wkhtmltopdf.exe" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-" < c:\hello_internet.html > correct.pdf

Obviously in hello_internet there is the content of @source.to_s

Running it results in the correct pdf being generated.

The correct pdf generated is here and the wrong is here.

I have no idea what can be wrong here.

Thanks.
