Django简单快速实现PUTDELETE方法

Posted 2020-10-22 北方姆Q

使用django的小伙伴们应该都知道我们是无法开心的处理PUT跟DELETE的

 1 $.ajax({
 2     url: \'XXX\',
 3     type: \'PUT\',
 4     dataType: \'json\',
 5     data: {
 6         \'s\': $("#select-id").find("option:selected").text()
 7     },
 8     success: function (data) {
 9         console.log(\'ok\');
10     }
11 })

 1 def func(request):
 2     if request.method == \'GET\':
 3         s = request.GET.get(\'s\', None)
 4         return XXX
 5     elif request.method == \'POST\':
 6         s = request.POST.get(\'s\', None)
 7         return XXX
 8     elif request.method == \'PUT\':
 9         s = request.PUT.get(\'s\', None)                    # 我们希望愉快的获取继续处理
10         return XXX
11     elif request.method == \'DELETE\':
12         s = request.DELETE.get(\'s\', None)                # 我们希望愉快的获取继续处理
13         return XXX
14     else:
15         pass

很不幸，在默认情况下，我们不能很轻易的根据restful来写url，但是，懒癌的威力是无穷大的！emmmmmmm.....

首先我们需要在django里某个app下添加一个中间件py文件，命名随意，这里我叫middleware

 1 #!/usr/bin/env python
 2 # -*- coding:utf8 -*-
 3 # __author__ = \'北方姆Q\'
 4 
 5 from django.http import QueryDict
 6 try:
 7     from django.utils.deprecation import MiddlewareMixin    # 1.10.x
 8 except ImportError:
 9     MiddlewareMixin = object                                # 1.4.x-1.9.x
10 
11 
12 class HttpPost2HttpOtherMiddleware(MiddlewareMixin):
13     def process_request(self, request):
14         """
15         可以继续添加HEAD、PATCH、OPTIONS以及自定义方法
16         HTTP_X_METHODOVERRIDE貌似是以前版本的key？？？
17         :param request: 经过原生中间件处理过后的请求
18         :return:
19         """
20         try:
21             http_method = request.META[\'REQUEST_METHOD\']
22             if http_method.upper() not in (\'GET\', \'POST\'):
23                 setattr(request, http_method.upper(), QueryDict(request.body))
24         # except KeyError:
25         #     http_method = request.META[\'HTTP_X_METHODOVERRIDE\']
26         #     if http_method.upper() not in (\'GET\', \'POST\'):
27         #         setattr(request, http_method.upper(), QueryDict(request.body))
28         except Exception:
29             pass
30         finally:
31             return None

然后在django的settings里注册此中间件就好了

 1 MIDDLEWARE = [
 2     \'django.middleware.security.SecurityMiddleware\',
 3     \'django.contrib.sessions.middleware.SessionMiddleware\',
 4     \'django.middleware.common.CommonMiddleware\',
 5     \'django.middleware.csrf.CsrfViewMiddleware\',
 6     \'django.contrib.auth.middleware.AuthenticationMiddleware\',
 7     \'django.contrib.messages.middleware.MessageMiddleware\',
 8     \'django.middleware.clickjacking.XFrameOptionsMiddleware\',
 9     \'yourappname.middleware.HttpPost2HttpOtherMiddleware\',                            # 改成自己的app名称哦
10 ]
