注意：网页授权两种方式

微信公众号开发网页授权获取用户基本信息

更多网页授权请查阅官网文档：网页授权静默授权静默授权即可以在用户关注的的时候，获取用户基本信息，此过程用户无感知。

第一步，通过工厂类转发请求 /// <returns></returns>public string HandleRequest(){string response = string.Empty;EventMessage em = EventMessage.LoadFromXml(RequestXml);if (em != null){switch (em.Event.ToLower()){case ("subscribe"):response = SubscribeEventHandler(em);//通过工厂类分发过来的请求，匹配到关注事件break;case ("unsubscribe"):response = Un_SubscribeEventHandler(em);break;case "click":response = ClickEventHandler(em);break;}}return response;}第二步，写用户关注事件WeChat.Messages.TextMessage tm = = em.FromUserName;tm.FromUserName = em.ToUserName;tm.CreateTime == 　　　　　　return tm.GenerateContent(); }第三步，根据得到的OpenId及accesstoken，即可获取用户基本信息（此处演示是将该用户存入数据库中）/// <summary>/// 根据OpenId将此条粉丝记录插入数据库中/// </summary>/// <param name="FromUserName"></param>/// <param name="ToUserName"></param>public void ShowUserInfo(string FromUserName, string ToUserName){try{Models.Users user = new Models.Users();DAL.User userInfo = new DAL.User();//获取accesstoken，获取用户基本信息需要Openid和accesstoken即可　　　　　　　　 accesstoken = Utility.Context.AccessToken;　　　　　　　　 string url = string.Format("https://api.weixin.qq.com/cgi-bin/user/info?access_token={0}&openid={1}&lang=zh_CN", accesstoken, FromUserName);string result = HttpUtility.GetData(url);XDocument doc = XmlUtility.ParseJson(result, "root");XElement root = doc.Root;if (root != null){#region 取值/存值subscribe = root.Element("subscribe").Value;//是否关注 1 是关注nickname = root.Element("nickname").Value;

顺便提下上文中用到的User类如下public class Users{/// <summary>/// 全局凭证唯一Id/// </summary>public string OpenID { get; set; }/// <summary>/// 公众号Id/// </summary>public string PublicId { get; set; }/// <summary>/// 用户Id/// </summary>public string UserID { get; set; }/// <summary>/// 昵称/// </summary>public string NickName { get; set; }/// <summary>/// 性别 1是男 0是女/// </summary>public int Sex { get; set; }/// <summary>/// 是否关注 1是关注/// </summary>public int Subscribe { get; set; }/// <summary>/// 国家/// </summary>public string Country { get; set; }/// <summary>/// 地区/// </summary>public string Province { get; set; }/// <summary>/// 城市/// </summary>public string City { get; set; }/// <summary>/// 关注时间/// </summary>public DateTime CreateDate { get; set; }/// <summary>/// 用户头像/// </summary>public string HeadimgUrl { get; set; }/// <summary>/// 第三方平台Id，可为空/// </summary>public string UnionID { get; set; }/// <summary>/// 用户取消关注时间/// </summary>public DateTime Un_Subscribe_Time { get; set; }}演示效果数据库中此时是存在10条数据的，当点击关注此公众号的时候，就将此用户的基本信息存入数据库了，数据库刷新后变成11条数据

微信公众号开发网页授权获取用户基本信息网页授权流程

具体介绍依然可参考官网文档：网页授权

第一步，判断该用户是否获取授权，若没有授权，则跳转至授权页面，若授权，则获取基本信息

核心代码/// <summary>/// 获取授权用户的基本信息,包括头像，姓名，等等(推荐方法）/// </summary>/// <param name="accessToken">用户授权之后的accessToken</param>/// <param name="openid">用户授权之后的openid</param>/// <returns></returns>public static ShouQuanWeiXinUserInfo GetShouQuanMessage(){//先判断是否有获取到用户授权的Code,HttpContext.Current.Session["ShouquanCode"]if (HttpContext.Current.Session["ShouquanCode"] == null|| HttpContext.Current.Session["ShouquanCode"].ToString()==""){HttpContext.Current.Session["ShouquanCode"] = "123";//用户授权的CodeGetShouQuanCodeUrl(HttpContext.Current.Request.Url.AbsoluteUri);}else if(HttpContext.Current.Request.QueryString["code"] == null || HttpContext.Current.Request.QueryString["code"] == ""){//用户授权的CodeGetShouQuanCodeUrl(HttpContext.Current.Request.Url.AbsoluteUri);}else{var model = ShouQuanAccessToken(HttpContext.Current.Request.QueryString["code"]);var url =$"http://www.php.cn/{model.access_token}&openid={model.openid}&lang=zh_CN";string gethtml = MyHttpHelper.HttpGet(url);var ac = JsonHelpers.ToObject<ShouQuanWeiXinUserInfo>(gethtml);return ac;}return null;}其中，用户授权的code方法如下： /// <summary>/// 重新获取用户授权的Code,可以获取用户的基本信息（头像，姓名，等等）(推荐用的方法）/// </summary>/// <param name="url">目标Url</param>/// <returns></returns>public static void GetShouQuanCodeUrl(string url){string CodeUrl = "";//加密过的urlstring value = HttpUtility.UrlEncode(url);//用户授权后的CodeCodeUrl = $"http://www.php.cn/{Appid}&redirect_uri={value}&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect";System.Web.HttpContext.Current.Response.Redirect(CodeUrl);//先跳转到微信的服务器，取得code后会跳回来这页面的}其中ShouQuanAccessToken方法 /// <summary>//用户授权之后，获取授权的Access_Token与基本的Access_Token是不同的(推荐方法）/// </summary>/// <param name="code">用户授权之后的Code</param>/// <returns></returns>public static OauthAccessToken ShouQuanAccessToken(string code){var url = $"http://www.php.cn/{Appid}&secret={Secret}&code={code}&grant_type=authorization_code";string gethtml = MyHttpHelper.HttpGet(url);OauthAccessToken ac = new
