【问题描述】：

我有一个简单的应用程序，允许您将图像上传到服务器，它设置在我的生产服务器上，由 django + uwsgi + ngnix 组成。

我在尝试上传图片时遇到问题。我收到以下错误：

错误

502 Bad Gateway
nginx/1.2.1

功能：

def upload(request):
    form = ImageForm()
    context = {'form':form,}
    context.update(csrf(request))


    if request.POST:
        form = ImageForm(request.POST, request.FILES)
        if form_is.valid():

            image = request.FILES.get('image')
            CarPhoto.objects.create(user=request.user,cars=1,description='dwq',image=image)
            return HttpResponseRedirect(reverse('transformer:kevin'))
    return     render_to_response('image.html',context,context_instance=RequestContext(request))

模板

 <form method="POST" enctype="multipart/form-data" action=".">

 {% csrf_token %}
 <div id="c">image</div> {{form.image}}
    <input type = "submit" value= "add" id="box2"/>
 </form>

【解决方案1】：

听起来您的 uWSGI 实例已经死亡或以不知道如何回答的方式失败。

除了 uWSGI 日志之外，还可以查看 nginx 日志，看看它会走多远。

也许您上传的文件太大，以至于阻塞了一些前端流传输部分。

编辑您的帖子以指示两个日志文件的输出，我们将看到。

【解决方案2】：

如果您的项目中包含第三方应用程序，那么它应该安装在您的服务器上，就像南方是第三方应用程序一样。考虑 south 包含在您的 settings.py 文件中，那么 south 也应该安装在您的服务器上。如果该模块在这里考虑南方，已经安装在服务器上，然后尝试升级它。因为您可能在本地机器上使用升级版模块，而服务器中安装了旧版本。
