微信公众号开发总结:
1、微信公众号分为三种:服务号、订阅号、企业号
2、微信公众号API官方文档http://qydev.weixin.qq.com/wiki/index.php?title=%E9%A6%96%E9%A1%B5
3、获取Token,然后调用是否Token过期,一般设置7200(两小时)过期。

public class TokenHelper { public string CorpID = "xxxxxxxxxx"; public string CorpSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; private string _Token; public string Token { get { return _Token; } set { _Token = value; } } public string GetToken(string URL) { /*获取AccessToken*/ string Access_Token = string.Format(@"https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={0}&corpsecret={1}",CorpID,CorpSecret); if (!string.IsNullOrEmpty(URL)) { Access_Token = URL; } HttpWebRequest request = WebRequest.Create(Access_Token) as HttpWebRequest; CookieContainer cookieContainer = new CookieContainer(); request.CookieContainer = cookieContainer; request.AllowAutoRedirect = true; request.Method = "POST"; request.ContentType = "text/html"; request.Headers.Add("charset", "utf-8"); HttpWebResponse response = request.GetResponse() as HttpWebResponse; Stream responseStream = response.GetResponseStream(); StreamReader sr = new StreamReader(responseStream, Encoding.UTF8); Token = sr.ReadToEnd(); return Token; }
4、获取Token后任意调用一个简单的方法,如提示过期,再重新获取。
