Django request get parameters
提问by Hulk
In a Django request I have the following:
在 Django 请求中，我有以下内容：
POST:<QueryDict: {u'section': [u'39'], u'MAINS': [u'137']}>
How do I get the values of sectionand MAINS?
我如何获得的价值section和MAINS？
if request.method == 'GET':
qd = request.GET
elif request.method == 'POST':
qd = request.POST
section_id = qd.__getitem__('section') or getlist....

You can use []to extract values from a QueryDictobject like you would any ordinary dictionary.
您可以像使用任何普通字典一样[]从QueryDict对象中提取值。
# HTTP POST variables
request.POST['section'] # => [39]
request.POST['MAINS'] # => [137]
# HTTP GET variables
request.GET['section'] # => [39]
request.GET['MAINS'] # => [137]
# HTTP POST and HTTP GET variables (Deprecated since Django 1.7)
request.REQUEST['section'] # => [39]
request.REQUEST['MAINS'] # => [137]

You may also use:
您还可以使用：
request.POST.get('section','') # => [39]
request.POST.get('MAINS','') # => [137]
request.GET.get('section','') # => [39]
request.GET.get('MAINS','') # => [137]
Using this ensures that you don't get an error. If the POST/GET data with any key is not defined then instead of raising an exception the fallback value (second argument of .get() will be used).
使用它可以确保您不会出错。如果未定义带有任何键的 POST/GET 数据，则不会引发异常，而是使用回退值（将使用 .get() 的第二个参数）。
