Django请求获取参数

发布于 2024-10-02 19:02:49 字数 361 浏览 3 评论 0原文

在 Django 请求中，我有以下内容：

POST:<QueryDict: {u'section': [u'39'], u'MAINS': [u'137']}>

如何获取 section 和 MAINS 的值？

if request.method == 'GET':
    qd = request.GET
elif request.method == 'POST':
    qd = request.POST

section_id = qd.__getitem__('section') or getlist....

In a Django request I have the following:

POST:<QueryDict: {u'section': [u'39'], u'MAINS': [u'137']}>

How do I get the values of section and MAINS?

if request.method == 'GET':
    qd = request.GET
elif request.method == 'POST':
    qd = request.POST

section_id = qd.__getitem__('section') or getlist....

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]

使用此功能可确保您不会收到错误。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）。

You may also use:

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).

您可以使用 [] 从 QueryDict 对象中提取值，就像提取任何普通字典一样。

# 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 can use [] to extract values from a QueryDict object like you would any ordinary dictionary.

# 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]
