ASP.NET微信公众号查看粉丝信息接口

本文实例为大家分享了asp.net微信粉丝信息接口查看代码，供大家参考，具体内容如下

微信token实体类：

 /// <summary>
 /// 微信token实体类
 /// </summary>
 public class wechattokenentity
 {
 public string access_token { get; set; }

 public string expires_in { get; set; }
 }

用户信息实体类

 /// <summary>
 /// 用户实体信息类
 /// </summary>
 public class wechatuserentity
 {
 public string subscribe { get; set; }

 public string openid { get; set; }

 public string nickname { get; set; }

 public string sex { get; set; }

 public string city { get; set; }

 public string province { get; set; }

 public string country { get; set; }

 public string headimgurl { get; set; }

 public string subscribe_time { get; set; }

 public string language { get; set; }
 }

微信辅助操作类

 public class wechatdemo
 {
 /*
  * 步骤：
  * 1.通过appid和secret请求微信url，得到token
  * 2.通过access_token和openid得到用户信息（头像地址等）
  * 3.通过access_token和media_id得到用户发送的微信消息
  * 
  */


 string appid = "wxxxxxxxxxxxxxx";
 string appsecret = "1234567890-==687";

 string wechaturl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}";


 public wechatdemo()
 {

 }

 /// <summary>
 /// 获取token信息
 /// </summary>
 /// <returns></returns>
 public wechattokenentity getwechattoken()
 {
  //请求的url地址
  string tokenurl = string.format(wechaturl, appid, appsecret);
  wechattokenentity mytoken;

  try
  {
  //声明并实例化一个webclient对象
  webclient client = new webclient();
  //从执行url下载数据
  byte[] pagedata = client.downloaddata(tokenurl);
  //把原始数据的byte数组转为字符串
  string jsonstr = encoding.default.getstring(pagedata);
  //初始化一个javascriptserializer json解析器
  //序列化注意：需要引用system.web.extensions
  javascriptserializer jss = new javascriptserializer();
  //将字符串反序列化为token对象
  mytoken = jss.deserialize<wechattokenentity>(jsonstr);
  }
  catch (webexception ex)
  {
  throw ex;
  }
  catch (exception ex)
  {
  throw ex;
  }

  return mytoken;
 }

 /// <summary>
 /// 获取用户信息
 /// </summary>
 /// <param name="accesstoken"></param>
 /// <param name="openid"></param>
 /// <returns></returns>
 public wechatuserentity getuserifo(string accesstoken, string openid)
 {
  wechatuserentity wue = new wechatuserentity();

  string url = "https://api.weixin.qq.com/cgi-bin/user/info?access_token={0}&openid={1}";

  url = string.format(url, accesstoken, openid);

  try
  {
  webclient wc = new webclient();
  byte[] pagedata = wc.downloaddata(url);
  string jsonstr = encoding.utf8.getstring(pagedata);
  javascriptserializer jss = new javascriptserializer();
  wue = jss.deserialize<wechatuserentity>(jsonstr);

  }
  catch (webexception ex)
  {
  throw ex;
  }
  catch (exception ex)
  {
  throw ex;
  }

  return wue;
 }

 public string getvoice(string accesstoken, string mediaid)
 {
  string voiceaddress = string.empty;
  string voiceurl = "http://file.api.weixin.qq.com/cgi-bin/media/get?access_token={0}&media_id={1}";
  voiceurl = string.format(voiceurl, accesstoken, mediaid);

  webclient wc = new webclient();
  byte[] pagedata = wc.downloaddata(voiceurl);
  string jsonstr = encoding.utf8.getstring(pagedata);

  //todo:获取声音
  voiceaddress = jsonstr;

  return voiceaddress;
 }

 /// <summary>
 /// 时间戳转为当前时间
 /// </summary>
 /// <param name="timestamp"></param>
 /// <returns></returns>
 public datetime timestamp2datetime(string timestamp)
 {
  datetime dtstart = timezone.currenttimezone.tolocaltime(new datetime(1970, 1, 1));
  long time = long.parse(timestamp + "0000000");
  timespan tonow = new timespan(time);
  return dtstart.add(tonow);
 }

 }

主程序:

 class program
 {
 static void main(string[] args)
 {
  wechatdemo wcd = new wechatdemo();
  wechattokenentity wte = wcd.getwechattoken();
  string token = wte.access_token;
  string openid = "ognvpt52xxxxxxxxxxxxxxxxxx";

  console.writeline("第一步：获得access_token:\n " + token + "\n");

  console.writeline("第二步：获得用户信息");
  wechatuserentity user = wcd.getuserifo(token, openid);

  console.writeline("\n昵称：" + user.nickname);
  console.writeline("国家：" + user.country);
  console.writeline("省份：" + user.province);
  console.writeline("城市：" + user.city);
  console.writeline("语言：" + user.language);
  console.writeline("性别：" + user.sex);
  console.writeline("openid：" + user.openid);
  console.writeline("是否订阅：" + user.subscribe);
  console.writeline("时间：" + wcd.timestamp2datetime(user.subscribe_time));
  console.writeline("头像地址：" + user.headimgurl);

  console.writeline("\n第三步：获取微信声音地址");
  string mediaid = "vwvnskvsldkvmsdlvkmdslkvmsld";

  string voiceaddress = wcd.getvoice(token, mediaid);
  console.writeline("声音地址：" + voiceaddress);
  console.read();
 }
 }

运行结果如图：
