Question

当我添加中间件时，TemplateResponse页面上的表单停止工作：提交会导致加载几分钟，然后导致负载均衡器错误。

在form中未定义中间件时，process_img，bot方法和settings.py查看完全按预期工作。

代码：

在settings.py中：

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'polls.views.ExampleMiddleware'
]

MIDDLEWARE_CLASSES = [
    'polls.views.ExampleMiddleware'
]

views.py中的中间件定义：

class ExampleMiddleware(MiddlewareMixin):
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        return response

    def process_template_response(self, request, response):
        if 'right' in request.POST:
            response.context_data['response'] = 'Sweet, thanks!'
        elif 'wrong' in request.POST:
            response.context_data['response'] = 'Awww, sorry'
        return response

views.py中的相关观点：

def bot(request):
    img_form = ImageUploadForm()
    context = {'img_form':img_form}
    if request.method=='POST':
        img_form = ImageUploadForm(request.POST, request.FILES)
        if img_form.is_valid():
            myfile = request.FILES['image']
            context = process_img(myfile)
            return TemplateResponse(request, 'polls/bot.html',context)
    return TemplateResponse(request, 'polls/bot.html',context)

什么打破了表单提交以及如何解决？

根据你的settings.py，你忘了在逗号后面加上逗号;＆＃39; django.contrib.messages.middleware.MessageMiddleware＆＃39;＆＃34;。

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'polls.views.ExampleMiddleware'
]

Django Middleware打破表单提交？
