django+wechat-python-sdk 如何创建微信服务器访问

1.版本说明：Python 2.7.10、Django (1.6.11.6)、centos7

2。步骤描述：

A。 django建立项目后启动服务器

django-admin.py startproject projtest

，看看是否正确：

cd projtest

配置projtest子目录下的setting.py文件，允许外部机器访问

[root@VM_4_128_centos projtest]# vim projtest/settings.py

将ALLOWED_HOSTS改为如下

ALLOWED_HOSTS = ['*']

然后启动让外机看到Can you access:

# python manage.py runserver 0.0.0.0:80

B，创建微信应用

 [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，编辑projtest/projtest/setting.py文件，添加Application

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',
)

注意：应用程序名称后面必须有逗号

E。在wechat目录下，覆盖view.py文件。代码如下（见网上例子）：

#!/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。编辑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
 
)

)

),我们配置
