Question

我正在从html创建pdf并且它被转换但没有图像。我也试过绝对的网址，但它仍然没有用 pdf功能：

def test_pdf(request):

    template = get_template('../templates/index.html')
    html = template.render(Context(data))
    filename = 'pdfs/'+str(random.random())+'.pdf'

    file = open(filename, "w+b")
    pisaStatus = pisa.CreatePDF(html.encode('utf-8'), dest=file, encoding='utf-8',link_callback=link_callback)
    # Return PDF document through a Django HTTP response
    file.seek(0)
    pdf = file.read()
    file.close()            # Don't forget to close the file handle
    return HttpResponse({"success":"success"})

def link_callback(uri, rel):

    sUrl = settings.STATIC_URL      # Typically /static/
    sRoot = settings.STATIC_ROOT    # Typically /home/userX/project_static/
    mUrl = settings.MEDIA_URL       # Typically /static/media/
    mRoot = settings.MEDIA_ROOT     # Typically /home/userX/project_static/media/


    if uri.startswith(mUrl):
        path = os.path.join(mRoot, uri.replace(mUrl, ""))

    elif uri.startswith(sUrl):
        path = os.path.join(sRoot, uri.replace(sUrl, ""))

    else:
        return uri  # handle absolute uri (ie: http://some.tld/foo.png)

    if not os.path.isfile(path):
            raise Exception(
                'media URI must start with %s or %s' % (sUrl, mUrl)
            )
    return path

设置文件：

PROJECT_ROOT = "/var/www/html/newclone/userapi/" 
MEDIA_ROOT = path.join(PROJECT_ROOT,'media')
MEDIA_URL = '/media/'
STATIC_ROOT = path.join(PROJECT_ROOT,'static-root')
STATIC_URL =  "/static/"

这有什么问题。 pdf生成成功但图像丢失

html文件：

<div class="h1"><img src="/media/xyz"></div>

Answer 1

甚至无法想象错误：在我的CSS中我写道：

.main{width:75%;}

因为这个图像不可见。我随意删除它，图像开始显示

xhtml2pdf没有选择图像
