我在尝试导入序列化的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，为什么它不处理导入时的UTF-8字符。我没有做任何特别的事情。另外，当我上次测试它时，相同的代码起作用。下面是我使用导出&进口我Google &我检查了那名相关的所有问题的StackOverflow（但答案没有我的线索所涉及的代码，在一个应用程序的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 

@user_passes_test(lambda u: u.is_superuser) 
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)) 

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字符会使它变成呕吐物，这是没有意义的，因为Python对UTF-8字符没有问题，而且我没有做任何奇怪的事情，导致代码突然以不同的方式对待它。

服务器何时启动python3 manage.py runserver看来，进口会工作得很好。当Django通过wsgi在Apache上运行时，它通过Django导入时无法正常工作。所以我猜测Apache是​​以某种方式干扰它的。现在它可以工作，只要我直接通过Django导入。
