问题描述
我正在尝试使用 pdf-kit 从 HTML 页面创建 PDF，然后将该 pdf 作为附件发送到电子邮件中。
这是我创建 pdf 的代码，这似乎有效：
html = render_template("office_report.html",role=role,name=name,owner=off,reps=reps,all_weekly=all_weekly,we=we,totals=totals,cog=cog,all_weekly_rpt=True,off_rpt=off_rpt,v=v,adonors=adonors,ae=ae,ov=ov,pay_total=pay_total)
options = {"enable-local-file-access": None}
try:
pdf=pdfkit.from_string(html,False,options=options)
files = pdf
except Exception as e:
print(e)
pdf='ERROR'
然后我尝试发送电子邮件，但不明白如何将 PDF 附加到电子邮件中。
try:
msg = Message('Owner Report ',sender = ("Brand Drivers",BD),recipients = ['jesswholt@gmail.com',BD,comp])
msg.body = "Weekly Report" + str(we)
with app.open_resource(files) as fp:
msg.attach("Owner Report","invoice/pdf",fp.read())
mail.mail.send(msg)
print('sent')
except Exception as e:
print(e)
这里是转换成PDF的HTML

解决方法
取而代之的是：
with app.open_resource(files) as fp:
msg.attach("Owner Report","invoice/pdf",fp.read())
就这样做：
msg.attach("Owner Report",pdf)
pdf（或 files）包含您的文件作为字节类型对象。因此您无需使用 open_resource 并读取文件，因为您已经拥有所需的数据。
