我正在尝试将我的第一个Django 1.0.2应用程序移植到OSX / Leopard上，使用Apache + mod_python 3.3.1 + python 2.6.1（全部以64位模式运行）并且我偶尔会遇到错误上传使用Django开发服务器测试时不存在的文件。
上传代码类似于Django文档中描述的代码：
class UploadFileForm(forms.Form):
file = forms.FileField()
description = forms.CharField(max_length=100)
notifygroup = forms.BooleanField(label='Notify Group?', required=False)
def upload_file(request, date, meetingid ):
print date, meetingid
if request.method == 'POST':
print 'before reloading the form...'
form = UploadFileForm(request.POST, request.FILES)
print 'after reloading the form'
if form.is_valid():
try:
handle_uploaded_file(request.FILES['file'], request.REQUEST['date'], request.REQUEST['description'], form.cleaned_data['notifygroup'], meetingid )
except:
return render_to_response('uploaded.html', { 'message': 'Error! File not uploaded!' })
return HttpResponseRedirect('/myapp/uploaded/')
else:
form = UploadFileForm()
return render_to_response('upload.html', {'form': form, 'date':date, 'meetingid':meetingid})
此代码通常可以正常工作，但有时（例如，每10次上传一次）并且在相当长的等待时间之后，它会因以下错误而失败：

我尝试使用mod_wsgi运行所有内容并没有区别。
有人知道我做错了什么吗？
提前感谢您的帮助！

更新：
虽然我成功上传了大文件（60+ MB），但是当它失败时它失败并且与上传的大小没有明显的关系，即它也失败了以前成功上传的10kB文件。

使用mod_wsgi让Firefox的问题消失了。
将我的研究限制在Apache和Safari之间的交互问题上，我偶然发现了Apache https://bugs.webkit.org/show_bug.cgi?id=5760的这个错误报告，该报告描述了与正在发生的事情非常相似的事情，并且显然仍然是开放的。读这个给了我尝试和禁用keepalive的想法，虽然我需要更广泛地测试它，但似乎问题已经消失。
简单：
BrowserMatch“Safari”nokeepalive
Apache配置中的就行了。

文件有多大？上传脚本超时可能需要很长时间，因此请尝试增加该脚本的执行时间。
答案 3 :(得分：0)
这里很长时间没有回答，但我自己经历了这个并尝试了一些事情来解决它。在我的情况下，如果有人在上传过程中取消了下载（或丢失了连接），就会发生这种情况。
您可以自己尝试一下，看看这是否是导致“IOError：请求数据读取错误”的原因：上传足够大的文件，您可以从计算机或路由器上拔下以太网电缆。稍等一下，看看是否收到错误。我每次都这样做！
