python-将html模板转换为带有图像的pdf
作者：互联网
我正在使用django并尝试呈现pdf发票,pdf成功生成,但是图像不在pdf中.
实际上,我想添加条形码图像,因此我动态生成了.svg文件,但不知道如何将其放入pdf.
这是我在做的..
from io import BytesIO
from django.http import HttpResponse
from django.template.loader import get_template
from xhtml2pdf import pisa
def render_to_pdf(template_src, context_dict={}):
template = get_template(template_src)
html = template.render(context_dict)
result = BytesIO()
pdf = pisa.pisaDocument(BytesIO(html.encode("ISO-8859-1")), result)
if not pdf.err:
return HttpResponse(result.getvalue(), content_type='application/pdf')
return None
html-
<body>
<div class="container-fluid">
<div class="row">
<div class="col-6">
<div class="row">
<div class="col-12">
<span>
{{ package_no_barcode }}
<br>
{{ package.package_no }}
....
查看-
class GenerateInvoicePdf(View):
def get(self, request, *args, **kwargs):
package = Package.objects.get(package_no=request.GET.get('package'))
address = package.purchase.order_product.delivery_location
CODE128 = barcode.get_barcode_class('code128')
package_no_barcode = CODE128(u'{pkg_no}'.format(pkg_no=package.package_no))
if request.user.display_username == seller.display_username:
data = {
'package':package,
'address':address,
'package_no_barcode':package_no_barcode,
}
pdf = render_to_pdf('pdf/invoice.html', data)
if pdf:
response = HttpResponse(pdf, content_type='application/pdf')
filename = "Invoice_%s.pdf" %(package)
content = "inline; filename='%s'" %(filename)
download = request.GET.get("download")
if download:
content = "attachment; filename='%s'" %(filename)
response['Content-Disposition'] = content
return response
return HttpResponse("Not found")
我还尝试了cid-< img src =“ cid：{{package_no_barcode}}”“ alt =” {{package.package_no}}“>
生成的svg的示例
CODE128 = barcode.get_barcode_class('code128')
package_no_barcode = CODE128(u'PLAI73664PJHS')
package_no_barcode.save('PSKK')
生成svg-

如何用此代码制作svg图像？
解决方法:
要获取在html中呈现的svg,您必须按原样获取svg文本(文本输出)并将其放入模板中,而无需使用< img>标签.

</body>在代码段中,您看到的是已经渲染的html,但是您需要找到获取文本的方式,并将其作为上下文变量传递给模板,就像使用package_no_barcode一样.
编辑
我已经使用jinja2和flask进行了测试,但是解决方案应该与django及其模板引擎相似.
首先,请确保在服务器代码中以字符串形式获取svg代码.然后,将其作为上下文变量传递到模板,就像我之前提到的那样.
在模板中,您需要“评估”之前传递的变量中的html或本例中的svg代码.为了使用jinja2做到这一点,我使用了安全过滤器.
<body>
<div class="container-fluid">

<div class="col-6">
<div class="row">
<div class="col-12">
{{ barcode | safe }}
<span></span>
</div>
</div>
</div>
</div>

</body>
结果,我得到了：
但是我想使用django的默认模板引擎,您需要使用内置的escape过滤器来获得类似的东西.
