微信辅助操作类

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：
