尝试导入序列化的XML文件时出现此错误。我从一个用于开发服务器的数据库中导出它，稍后我将它导入另一个开发服务器上的另一个数据库（在同一台机器上）。我很困惑为什么它不会在导入时处理UTF-8字符。我没有做任何特别的事。另外，当我上次测试它时，相同的代码工作。这是我用来导出和输出的代码。导入，在应用的views.py ...

from django.shortcuts import render, render_to_response, get_object_or_404
from django.http import HttpResponseRedirect, HttpResponse
from django.contrib.auth.decorators import user_passes_test
from django.core import serializers

def export_serial(request):
    '''
    This exports data using Django serializing.
    See: https://docs.djangoproject.com/en/dev/topics/serialization/
    '''
    XMLSerializer = serializers.get_serializer("xml")
    xml_serializer = XMLSerializer()
    xml_serializer.serialize(list(ThisModel.objects.all()) 
                        + list(ThatModel.objects.all())
                          + list(ThirdModel.objects.all()))
    data = xml_serializer.getvalue()

    response = HttpResponse(mimetype='text/xml')
    response['Content-Disposition'] = 'attachment; filename=my-backup.xml'
    response.write(data)
    return response


@user_passes_test(lambda u: u.is_superuser)
def import_serial(request):
    '''
    This is for importing data that was saved/backed up, as serialized.
    '''
    xmlfile = '/home/zamphatta/path/to/my-backup.xml'
    serialfile = open(xmlfile,'r')
    data = serialfile.read()
    serialfile.close()

    for deserialized_object in serializers.deserialize("xml", data):
        deserialized_object.save()

    template = loader.get_template('z-style/index.htm')
    context = RequestContext(request, {
        'title': data,
    })
    return HttpResponse(template.render(context))

我用谷歌搜索＆amp;我检查了所有相关的StackOverflow问题（但答案并不能让我回答这个问题），并且仍然不知道为什么这会给我带来这个错误。我所知道的是非ascii字符正在使它变得愚蠢，这没有意义'因为Python没有UTF-8字符的问题而且我没有做任何会导致代码突然对待它的奇怪的东西

更新：以下是错误消息的更全面版本...

似乎服务器启动时python3 manage.py runserver，导入工作正常。当Django通过wsgi在Apache上运行时，当我通过Django导入它时，它无法正常工作。所以我猜测Apache在某种程度上干扰了它。它现在有效，只要我直接导入Django。

'ascii'编解码器无法解码位置5367中的字节0xe2：序数不在范围内（128）
