今天小編就為大家分享一篇利用django+wechat-python-sdk 創(chuàng)建微信服務(wù)器接入的方法，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。一起跟小編過(guò)來(lái)看看吧

1、版本說(shuō)明：python 2.7.10, Django (1.6.11.6),centos7

2、步驟說(shuō)明：

A、django 建立項(xiàng)目

django-admin.py startproject projtest

之后啟動(dòng)服務(wù)器，看看是否正確：

cd projtest

配置 projtest子目錄下面的setting.py文件，允許外部機(jī)器訪問(wèn)

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

把其中ALLOWED_HOSTS改成如下

ALLOWED_HOSTS = ['*']

然后啟動(dòng)，外部機(jī)器看看能否訪問(wèn)到：

# python manage.py runserver 0.0.0.0:80

利用django+wechat-python-sdk 創(chuàng)建微信服務(wù)器接入

B、創(chuàng)建應(yīng) 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、安裝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，加入應(yīng)用

目錄結(jié)構(gòu)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：應(yīng)用名稱后面要有逗號(hào)

E、在wechat目錄下，重寫(xiě)views.py文件，代碼如下（參考網(wǎng)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):
 #這里我當(dāng)時(shí)寫(xiě)成了防止跨站請(qǐng)求偽造，其實(shí)不是這樣的，恰恰相反。因?yàn)閐jango默認(rèn)是開(kāi)啟了csrf防護(hù)中間件的
 #所以這里使用@csrf_exempt是單獨(dú)為這個(gè)函數(shù)去掉這個(gè)防護(hù)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'消息類型: {}'.format(message.type))
  else:
    rsp = wechat.response_text('check error')
  return HttpResponse(rsp)

F、修改projtest/projtest/urls.py ，添加映射到微信應(yīng)用（類似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、微信提交配置通過(guò)

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

以上這篇利用django+wechat-python-sdk 創(chuàng)建微信服務(wù)器接入的方法就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
