Convert html to pdf using Python/Flask
提问by Dmitry_Mahrachev
I want to generate pdf file from html using Python + Flask. To do this, I use xhtml2pdf. Here is my code:
我想使用 Python + Flask 从 html 生成 pdf 文件。为此，我使用 xhtml2pdf。这是我的代码：
def main():
pdf = StringIO()
pdf = create_pdf(render_template('cvTemplate.html', user=user))
pdf_out = pdf.getvalue()
response = make_response(pdf_out)
return response
def create_pdf(pdf_data):
pdf = StringIO()
pisa.CreatePDF(StringIO(pdf_data.encode('utf-8')), pdf)
return pdf
In this code file is generating on the fly. BUT! xhtml2pdf doesn't support many styles in CSS, because of this big problem to mark page correctly. I found another instrument(wkhtmltopdf). But when I wrote something like:
在这个代码文件中是动态生成的。但！xhtml2pdf 不支持 CSS 中的许多样式，因为正确标记页面这个大问题。我找到了另一种乐器（wkhtmltopdf）。但是当我写下类似的东西时：
pdf = StringIO()
data = render_template('cvTemplate1.html', user=user)
WKhtmlToPdf(data.encode('utf-8'), pdf)
return pdf
Was raised error:
被引发错误：
AttributeError: 'cStringIO.StringO' object has no attribute 'rfind'
And my question is how to convert html to pdf using wkhtmltopdf (with generating file on the fly) in Flask?

Have you tried with Flask-WeasyPrint, which uses WeasyPrint? There are good examples in their web sites so I don't replicate them here.
您是否尝试过使用WeasyPrint 的Flask- WeasyPrint？他们的网站上有很好的例子，所以我不在这里复制它们。
