详解asp.net完成微信民众账号接口开辟要领【C#.Net教程】,asp.net 开发

这篇文章主如果一篇详解asp.net完成微信民众账号接口开辟要领，感兴趣的小伙伴们能够参考一下

提及微信民众帐号，人人都不会生疏，运用这个平台能给网站或体系增添一个新亮点，直接进入正题吧，在运用之前一定要仔细浏览官方API文档。
运用.net完成的要领：
//微信接口地点页面代码:

weixin _wx = new weixin(); 
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)) //要求处置惩罚 
{ 
_wx.Handle(postStr); 
} 
} 
else 
{ 
_wx.Auth(); 
}
