我正在关注xhtml2pdf
guides。
我使用了一个示例html文件并保存为test.html:
<html>
<head>
<style>
@page {
size: a4 portrait;
@frame header_frame { # Static Frame
-pdf-frame-content: header_content;
left: 50pt; width: 512pt; top: 50pt; height: 40pt;
}
@frame content_frame { # Content Frame
left: 50pt; width: 512pt; top: 90pt; height: 632pt;
}
@frame footer_frame { # Another static Frame
-pdf-frame-content: footer_content;
left: 50pt; width: 512pt; top: 772pt; height: 20pt;
}
}
</style>
</head>
<body>
<!-- Content for Static Frame 'header_frame' -->
<div id="header_content">Lyrics-R-Us</div>
<!-- Content for Static Frame 'footer_frame' -->
<div id="footer_content">(c) - page <pdf:pagenumber>
of <pdf:pagecount>
</div>
<!-- HTML Content -->
To PDF or not to PDF
</body>
</html>
然后我将此文件作为字符串读入并尝试创建pdf:
with open('test.html','r') as f:
sourceHtml = f.read()
outputFilename = "test.pdf"
resultFile = open(outputFilename , "w+b")
pisaStatus = pisa.CreatePDF(sourceHtml,dest=resultFile)
resultFile.close()
但是,我得到以下错误回溯:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\xhtml2pdf\document.py", line 89, in pisaDocument

src, properties = self._parseDeclarationGroup(src.lstrip())
File "C:\Python27\lib\site-packages\xhtml2pdf\w3c\cssParser.py", line 1017, in _parseDeclarationGroup
raise self.ParseError('Declaration group closing \'}\' not found', src, ctxsrc)
xhtml2pdf.w3c.cssParser.CSSParseError: Declaration group closing '}' not found:: (u'{ ', u'# Static Frame\n ')
这似乎意味着css代码中缺少}
。然而,对我来说似乎很好。我正在使用Windows,所以我认为这可能与\r\n
行EOL有关 - 但事实并非如此。
谁能看到我做错了什么?

当我将所有CSS定义放在一行中时,它可以正常工作:
<html>
<head>
<style>
@page {size: a4 portrait; @frame header_frame {-pdf-frame-content: header_content; left: 50pt; width: 512pt; top: 50pt; height: 40pt;} @frame content_frame { left: 50pt; width: 512pt; top: 90pt; height: 632pt;} @frame footer_frame { -pdf-frame-content: footer_content; left: 50pt; width: 512pt; top: 772pt; height: 20pt;}}
</style>
</head>
...
注意,如果我将它们分开,以便每个定义都有一个单独的行,它就会挂起。

您遇到的问题与错误完全无关,但仍然涉及您的CSS。
CSS中的注释是使用/*
和*/
创建的,而不是像Python中的#
。如果你删除&#34;评论&#34;从您的文件中,它由pisa解析和创建。这也是您的单行示例有效的原因,但它们并未包括在内。
