wkhtmltopdf error

说明

html转个pdf 一堆bug , 有一个记录一个.. python27的， 很抱歉我只找到了原因，没找到解决方案。

bug

执行

>>> import pdfkit>>> pdfkit.from_file('aa.html', 'out.pdf')

error

Traceback (most recent call last):  File "<stdin>", line 1, in <module>  File "/usr/local/python27/lib/python2.7/site-packages/pdfkit/api.py", line 49, in from_file    return r.to_pdf(output_path)  File "/usr/local/python27/lib/python2.7/site-packages/pdfkit/pdfkit.py", line 156, in to_pdf    raise IOError('wkhtmltopdf reported an error:\n' + stderr)IOError: wkhtmltopdf reported an error:Loading pages (1/6)Counting pages (2/6)Warning: Received createRequest signal on a disposed ResourceObject's NetworkAccessManager. This might be an indication of an iframe taking too long to load.Resolving links (4/6)Loading headers and footers (5/6)Printing pages (6/6)DoneExit with code 1 due to network error: ContentNotFoundError

此时此刻我想… 这里有个警告，貌似什么没加载到 ,如下

Warning: Received createRequest signal on a disposed ResourceObject’s NetworkAccessManager. This might be an indication of an iframe taking too long to load.

执行完命令之后，是生成了pdf的，但是也抛了异常，我想如果拦截异常不处理也是可以的，没发现影响功能。不过还是查了一下….

原因

是因为css文件引用了外部的资源，如：字体，图片，iframe加载等。

我这里是引用了外部的一套字体文件，然后就报了这个错。
