django+wechat-python-sdk 创建微信服务器接入的方法
1、版本说明 :python 2.7.10, Django (1.6.11.6),centos7
2、步骤说明:
A、django 建立项目
django-admin.py startproject projtest
之后启动服务器,看看是否正确:
cd projtest
配置 projtest子目录下面的setting.py文件,允许外部机器访问
[root@VM_4_128_centos projtest]# vim projtest/settings.py
把其中ALLOWED_HOSTS改成如下
ALLOWED_HOSTS = ['*']
然后启动,外部机器 看看能否访问到:
# python manage.py runserver 0.0.0.0:80
B、创建应 用wechat
[root@VM_4_128_centos projtest]# python manage.py startapp wechat [root@VM_4_128_centos projtest]# ls manage.py projtest wetchat
C、安装wechat_sdk
[root@VM_4_128_centos projtest]# pip install wechat-sdk Requirement already satisfied: wechat-sdk in /usr/lib/python2.7/site-packages Requirement already satisfied: six==1.10.0 in /usr/lib/python2.7/site-packages (from wechat-sdk) Requirement already satisfied: requests==2.6.0 in /usr/lib/python2.7/site-packages (from wechat-sdk) Requirement already satisfied: pycrypto==2.6.1 in /usr/lib64/python2.7/site-packages (from wechat-sdk) Requirement already satisfied: xmltodict==0.9.2 in /usr/lib/python2.7/site-packages (from wechat-sdk)
D、修改projtest/projtest/setting.py文件,加入应用
目录结构如下:
|-- manage.py |-- projtest | |-- __init__.py | |-- __init__.pyc | |-- settings.py | |-- settings.pyc | |-- urls.py | |-- urls.pyc | |-- wsgi.py | `-- wsgi.pyc `-- wetchat |-- __init__.py |-- admin.py |-- models.py |-- tests.py `-- views.py
vim projtest/settings.py
`-- wetchatINSTALLED_APPS = ( 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'wechat', )
注:应用名称后面要有逗号
E、在wechat目录下,重写views.py文件,代码如下(参考网上例子):
#!/usr/bin/python # -*- coding: utf-8 -*- # Create your views here. from django.shortcuts import render from django.http import HttpResponse from django.views.decorators.csrf import csrf_exempt from django.views.generic.base import View from django.template import loader, Context from wechat_sdk import WechatBasic token = 'zwbswx' class WeChat(View): #这里我当时写成了防止跨站请求伪造,其实不是这样的,恰恰相反。因为django默认是开启了csrf防护中间件的 #所以这里使用@csrf_exempt是单独为这个函数去掉这个防护功能。 @csrf_exempt def dispatch(self, *args, **kwargs): return super(WeChat, self).dispatch(*args, **kwargs) def get(self, request): wechat = WechatBasic(token=token) if wechat.check_signature(signature=request.GET['signature'], timestamp=request.GET['timestamp'], nonce=request.GET['nonce']): if request.method == 'GET': rsp = request.GET.get('echostr', 'error') else: wechat.parse_data(request.body) message = wechat.get_message() rsp = wechat.response_text(u'消息类型: {}'.format(message.type)) else: rsp = wechat.response_text('check error') return HttpResponse(rsp)
F、修改projtest/projtest/urls.py ,添加映射到微信应用(类似servlet)
[root@VM_4_128_centos projtest]# vim projtest/urls.py
from django.conf.urls import patterns, include, url from django.contrib import admin from wechat import views as wt_views ##增加本行 admin.autodiscover() urlpatterns = patterns('', # Examples: # url(r'^$', 'projtest.views.home', name='home'), # url(r'^blog/', include('blog.urls')), url(r'^admin/', include(admin.site.urls)), url(r'^wechat', wt_views.WeChat.as_view()), ##增加本行 )
)
G、微信提交配置通过
05/Jun/2017 03:31:01] "GET /wechat?signature=8a75afb21cf821bbc4e2535119aa05be5c987112&echostr=13869464754252084605×tamp=1496633461&nonce=3957453572 HTTP/1.0" 301 0 [05/Jun/2017 03:31:01] "GET /wechat/?signature=8a75afb21cf821bbc4e2535119aa05be5c987112&echostr=13869464754252084605×tamp=1496633461&nonce=3957453572 HTTP/1.0" 200 20
THE END
