1 公司提供接口，微信平台可以通过访问我们的接口，进行数据交互，通过xml。
2 http://mp.weixin.qq.com/ 微信服务号平台，输入用户名密码进入高级功能-开发者模式，
3 申请服务号之后，微信会提供appid和AppSecret两个参数，根据这两个参数可以获取token，token作为你服务号和微信交互的证明。
4 接下里就是完成自己的接口部分的开发，然后接口的服务器配置地址输入微信服务号的服务器配置url，本地的项目地址是不行的，得是能访问的地址
5 接口的开发，接受xml，然后返回xml。
6 页面不需要写什么，但是注意编码，微信的编码是utf-8的，所以一定要注意，gb2312或者默认是无法访问的
<%@ Page Language="C#" ResponseEncoding="utf-8" ContentType="text/xml" AutoEventWireup="true" CodeBehind="weixin.aspx.cs" Inherits="weixin.weixin" %>
7 后台代码：
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["city"] != null && Request.QueryString["city"].ToString() != "")
{
cityname = Request.QueryString["city"].ToString();
}
weixinEntity wx = new weixinEntity();
string postStr = "";
if (Request.HttpMethod.ToLower() == "post" )
{
Stream s = System.Web.HttpContext.Current.Request.InputStream;
byte[] b = new byte[s.Length];
s.Read(b, 0, (int)s.Length);
postStr = Encoding.UTF8.GetString(b);
if (!string.IsNullOrEmpty(postStr)) //请求处理
{
wx.Handle(postStr);
}
}
else
{
wx.Auth();
