接入微信公众平台开发，开发者需要按照如下步骤完成：
- 填写服务器配置
- 验证服务器地址的有效性
- 依据接口文档实现业务逻辑
填写服务器配置
说明：现在选择提交肯定是验证token失败，因为还需要完成代码逻辑
注意：如果没有注册公众号，也可以利用测试平台完成上述过程(在开发过程中建议使用测试账号，待真实上线时使用自己真实的公众号即可)
测试平台：http://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login
验证服务器地址的有效性
开发者提交信息后，微信服务器将发送GET请求到填写的服务器地址URL上，GET请求携带四个参数
- 原理 开发者通过检验signature对请求进行校验。若确认此次GET请求来自微信服务器，请原样返回echostr参数内容，则接入生效，成为开发者成功，否则接入失败
- 流程
- 将token、timestamp、nonce三个参数进行字典序排序
- 将三个参数字符串拼接成一个字符串进行sha1加密
- 开发者获得加密后的字符串可与signature对比，标识该请求来源于微信
- 搭建Django服务
创建Django工程并添加应用
修改配置文件settings.py
代码语言：javascript复制ALLOWED_HOSTS = [<span class="hljs-string">"*"</span>]
<span class="hljs-comment"># Application definition</span>
INSTALLED_APPS = [
<span class="hljs-string">'django.contrib.admin'</span>,
<span class="hljs-string">'django.contrib.auth'</span>,
<span class="hljs-string">'django.contrib.contenttypes'</span>,
<span class="hljs-string">'django.contrib.sessions'</span>,
<span class="hljs-string">'django.contrib.messages'</span>,
<span class="hljs-string">'django.contrib.staticfiles'</span>,
<span class="hljs-string">'myApp'</span>,
]
添加主路由与子路由
project/urls.py
代码语言：javascript复制<span class="hljs-keyword">from</span> django.contrib <span class="hljs-keyword">import</span> admin
<span class="hljs-keyword">from</span> django.urls <span class="hljs-keyword">import</span> path, re_path, include
urlpatterns = [
path(<span class="hljs-string">'admin/'</span>, admin.site.urls),
path(<span class="hljs-string">''</span>, include((<span class="hljs-string">"myApp.urls"</span>, <span class="hljs-string">"myApp"</span>), namespace=<span class="hljs-string">"myApp"</span>)),
]
myApp/urls.py
代码语言：javascript复制<span class="hljs-keyword">from</span> django.urls <span class="hljs-keyword">import</span> path, re_path
<span class="hljs-keyword">from</span> myApp <span class="hljs-keyword">import</span> views
urlpatterns = [
path(<span class="hljs-string">r'index/'</span>, views.index),
]
添加测试视图
myApp/views.py
代码语言：javascript复制<span class="hljs-keyword">from</span> django.shortcuts <span class="hljs-keyword">import</span> render, HttpResponse
<span class="hljs-comment"># Create your views here.</span>
<span class="hljs-function"><span class="hljs-keyword">def</span> <span class="hljs-title">index</span><span class="hljs-params">(request)</span>:</span>
<span class="hljs-keyword">return</span> HttpResponse(<span class="hljs-string">"sunck is a good man"</span>)
测试基础服务
启动命令：python manage.py runserver 0.0.0.0:8080
浏览器地址栏输入：http://39.107.226.105:8080/index/
验证微信服务器请求
myApp/urls.py
代码语言：javascript复制<span class="hljs-keyword">from</span> django.urls <span class="hljs-keyword">import</span> path, re_path

myApp/views.py

timestamp = request.GET.get(<span class="hljs-string">'timestamp'</span>, <span class="hljs-keyword">None</span>)

hashlist = [token, timestamp, nonce]
hashlist.sort()
hashstr = <span class="hljs-string">''</span>.join([s <span class="hljs-keyword">for</span> s <span class="hljs-keyword">in</span> hashlist])
hashstr = hashlib.sha1(hashstr.encode(<span class="hljs-string">"utf-8"</span>)).hexdigest()
<span class="hljs-keyword">if</span> hashstr == signature:
<span class="hljs-keyword">return</span> HttpResponse(echostr)
<span class="hljs-keyword">else</span>:
<span class="hljs-keyword">return</span> HttpResponse(<span class="hljs-string">"field"</span>)
启动Django服务
启动服务：python manage.py runserver 0.0.0.0:8080
配置Nginx
因为微信服务器只请求80或者443端口，但是DJango服务无法使用这两个端口。所以需要配合Nginx作为反向代理分发请求给DJango服务
代码语言：javascript复制 user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
use epoll;
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request"'
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
charset koi8-r;
location / {
proxy_pass http://39.107.226.105:8080;
}
location /static {
alias /var/www/ty/collectedstatic/;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}重启Nginx服务：systemctl restart nginx.service
浏览器地址栏输入：http://39.107.226.105/index/
注意：此时无需输入8080端口，默认使用80端口请求Nginx服务，Nginx再将请求转发给DJango服务
