Question

我在开发中的Django项目中使用wkhtmltopdf收到以下错误。如果我尝试使用Apache服务器运行它，则返回的状态代码是6而不是1.

命令＆＃39; [＆＃39; wkhtmltopdf＆＃39;，＆＃39; - 禁用-javascript＆＃39;，＆＃39; - 编码＆＃39;， u＆＃39; utf8＆＃39;，＆＃39; - 安静＆＃39;，你＆＃39;错误＆＃39;，＆＃39; /tmp/wkhtmltopdfnUwu3t.html'，＆＃39; - ＆＃ 39;]＆＃39; 返回非零退出状态1

这是我的观点。

class MyPDF(OrgOwnerMixin, PDFTemplateView):
    filename = 'my_pdf.pdf'
    template_name = 'pdf/test.html'

    def get_object(self, *args, **kwargs):
        return Organisation.objects.get(slug=self.kwargs['slug'])

    def get_context_data(self, *args, **kwargs):
        ctx = super(MyPDF, self).get_context_data(*args, **kwargs)
        ctx['object'] = self.get_object()
        return ctx

这是Traceback：

非常感谢任何帮助

看到PDFTemplateView我怀疑你正在使用django-wkhtmltopdf。

查看追溯的Exception Value：

Exception Value: Command '['wkhtmltopdf', '--disable-javascript', '--encoding', u'utf8', '--quiet', u'False', '/tmp/wkhtmltopdfEG5K8j.html', '-']' returned non-zero exit status 1

我在此处看到了可疑参数False：--quiet False /tmp/wkhtmltopdfEG5K8j.html

但是，我刚刚进行了全新安装（最新的Django 2.x和django-wkhtmltopdf==3.1.0），我无法重现您的问题。但是我注意到一件事：你继承了MyPDF的{{1}}课程，你忘记在这里发帖了。

我怀疑在OrgOwnerMixin OR中OrgOwnerMixin继承的任何类（如果有的话）中都有类似的内容：

OrgOwnerMixin

这会导致class OrgOwnerMixin: cmd_options = {'quiet': False}作为参数传递给命令行中的False标志，从而触发您的异常。

如果要禁用--quiet标志，则必须执行以下操作：

--quiet

虽然我没有在文档中看到这一点，但我可以在代码中清楚地看到，只有当您将cmd_options = {'quiet': None}作为选项的值传递时才会从命令行中删除它。您可以通过查看wkhtmltopdf.utils._options_to_args函数来查看此内容。

Answer 2

我有一个类似的问题，但这是由于我的模板链接到外部文件。我发现解决方案是将'enable-local-file-access': True添加到我的选项中：

cmd_options = {'quiet': None, 'enable-local-file-access': True}
