利用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-sdkRequirement already satisfied: wechat-sdk in /usr/lib/python2.7/site-packagesRequirement 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 renderfrom django.http import HttpResponsefrom django.views.decorators.csrf import csrf_exemptfrom django.views.generic.base import Viewfrom django.template import loader, Context from wechat_sdk import WechatBasictoken = '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)
