Django簡單快速實現PUT、DELETE方法

使用django的小伙伴們應該都知道我們是無法開心的處理PUT跟DELETE的

$.ajax({
    url: 'XXX',
    type: 'PUT',
    dataType: 'json',
    data: {
        's': $("#select-id").find("option:selected").text()
    },
    success: function (data) {
        console.log('ok');
    }
})

def func(request):
    if request.method == 'GET':
        s = request.GET.get('s', None)
        return XXX
    elif request.method == 'POST':
        s = request.POST.get('s', None)
        return XXX
    elif request.method == 'PUT':
        s = request.PUT.get('s', None)                    # 我們希望愉快的獲取繼續處理
        return XXX
    elif request.method == 'DELETE':
        s = request.DELETE.get('s', None)                # 我們希望愉快的獲取繼續處理
        return XXX
    else:
        pass

很不幸，在默認情況下，我們不能很輕易的根據restful來寫url，但是，懶癌的威力是無窮大的！emmmmmmm.....

首先我們需要在django里某個app下添加一個中間件py文件，命名隨意，這里我叫middleware

#!/usr/bin/env python
# -*- coding:utf8 -*-
# __author__ = '北方姆Q'

from django.http import QueryDict
try:
    from django.utils.deprecation import MiddlewareMixin    # 1.10.x
except ImportError:
    MiddlewareMixin = object                                # 1.4.x-1.9.x


class HttpPost2HttpOtherMiddleware(MiddlewareMixin):
    def process_request(self, request):
        """
        可以繼續添加HEAD、PATCH、OPTIONS以及自定義方法
        HTTP_X_METHODOVERRIDE貌似是以前版本的key？？？
        :param request: 經過原生中間件處理過后的請求
        :return:
        """
        try:
            http_method = request.META['REQUEST_METHOD']
            if http_method.upper() not in ('GET', 'POST'):
                setattr(request, http_method.upper(), QueryDict(request.body))
        # except KeyError:
        #     http_method = request.META['HTTP_X_METHODOVERRIDE']
        #     if http_method.upper() not in ('GET', 'POST'):
        #         setattr(request, http_method.upper(), QueryDict(request.body))
        except Exception:
            pass
        finally:
            return None

然后在django的settings里注冊此中間件就好了

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',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'yourappname.middleware.HttpPost2HttpOtherMiddleware',                            # 改成自己的app名稱哦
]
