当我提交一个具有 method="POST" 的表单时，处理它的视图正在获取方法 GET，我似乎无法让它成为文件上传所必需的 POST。只是罐装我现有的（一周前工作，在升级到 1.4 之前）并尝试使用从https://docs.djangoproject.com/en/dev/topics/http/file-uploads/上传示例的表格，你能看出这里出了什么问题吗？我尝试使用 Chrome Incognito 进行新会话，结果相同。当我不包含 method="POST" 时，它使用方法 GET 提交，并且这些字段包含在电子邮件的 request.GET 字典中。但是，当我更改为 POST/post 时，它仍然是 GET 方法，并且字段不在 request.POST 或 request.GET 字典中。Django 1.4 中是否存在导致此行为的错误？有什么我想念的吗？我试图做一个简单的例子来排除所有无关的潜在变量。

简单的测试场景：

网址.py：

url(r'^upload_test/+$', 'views.presentation.UploadTest'),
url(r'^uploaded_test/+$', 'views.presentation.UploadedTest'),

意见/presentation.py：

def Notify(subject, body):
    """
        Send an email to <to_email>, from <from_email> with the
        subject and body supplied.
    """
    send_mail(subject, body, '<from_email>', ['<to_email>'], fail_silently=False)

def UploadTest(request):
    Notify("UploadTest", "METHOD: " + str(request.method) + """

    """ + str(request))
    return render_to_response('upload.htm', context_instance=RequestContext(request))

def UploadedTest(request):
    Notify("UploadedTest", "METHOD: " + str(request.method) + """

    """ + str(request) + """

    FILES:
    """ + str(request.FILES))
    return render_to_response('upload.htm', context_instance=RequestContext(request))

upload.htm（注意方法是POST，我也尝试了小写以防万一）：

<form
    id="upload_file_form"
    action="/uploaded_test"
    method="POST"
    enctype="multipart/form-data"
    target="_blank"
>
    {% csrf_token %}
    <input type="text" name="extra_field" value="extra post field" />
    <input type="file" name="upload_file" id="upload_file" />
    <input type="submit" name="upload" value="Submit" />
</form>

简单测试场景的结果

我收到的电子邮件（注意第一个是预提交的表单，第二个是发布的表单页面）：

值得怀疑，但我的 wsgi 文件或 Apache 站点指令中可能有问题。以下是这些，以防万一：

...wsgi：

import os
import sys

path = '/var'
if path not in sys.path:
   sys.path.append(path)

path = '/var/www'
if path not in sys.path:
   sys.path.append(path)

path = '/var/www/site'
if path not in sys.path:
   sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'site.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

启用 Apache 站点的指令：

    RewriteEngine on
    RewriteCond %{HTTPS} !=on
    RewriteRule ^/(.*) https://%{SERVER_NAME}/$1 [R,L]

也许我需要阅读更多关于 urls.py 或正则表达式的信息。我不小心将表单更改为action="uploaded_test"不带斜线的帖子，并收到一个 404 错误报告，其中 request.method 为“POST”（什么？！@#$*&）...？？？这意味着它必须与我的发布网址有关！我有它：

'^uploaded_test/+$'

我将其更改为：

'^uploaded_test$'

并验证该表格已发布到action="/uploaded_test"并且有效！我将 urls.py 更改为：

'^uploaded_test/$'

并将表格更改为发布到action="/uploaded_test/"，它也有效！我的大多数 urls 条目中都有 /+，因此我可以接受 /loc 或 /loc/ 的许多条目。我想我现在会把它们改回来。我不知道这是一个错误还是我不了解正则表达式/+语法的东西。

您是否在表示层中尝试过 if-else 语句？例如if request.method == 'POST':，然后是您的其余代码。
