Question

我正在使用pdfkit从html字符串创建pdf。

这是我的代码：

cover = '<html> <head></head><body><h1>hello<h1></body> </html>'
body = "<html> <head></head><body><h1>hello<h1></body> </html>"
pdf = dfkit.from_string(body, False, cover=cover, cover_first=True)

如果我不使用掩护，效果很好，如果我使用掩护，则会引发以下错误：

我认为这可能是因为我使用的是字符串而不是html的URL。

因此，我添加了一个返回html的终结点，即使它仍然引发相同的错误。

这是它的url版本：django端点

options = {'encoding': "UTF-8"}
cover = '{}/api/blahblah/blah'.format('localhost:8088')
body = "<html> <head></head><body><h1>hello<h1></body> </html>"
pdf = dfkit.from_string(body, False, options =options, cover=cover, cover_first=True)

如果尝试在post man上将其击中，则端点在外部可以正常工作。但是，如果将它与pdfkit一起使用，则会引发ConnectionRefusedError。

如果我一起取下盖子，它可以正常工作，它将创建pdf。但是，需要掩护。有什么建议吗？

解决了这个问题。我完全忘记了我在docker容器中运行它，所以localhost从未解决。

python pdfkit不呈现封面
