WeChat public account development web page authorizes to obtain user basic information

If the user accesses a third-party webpage in the WeChat client, the official account can obtain the user's basic information through the WeChat webpage authorization mechanism to implement business logic.
Note: There are two ways to authorize web pages
For more web authorization, please refer to the official website documentation: Web authorization
Silent authorization
Silent authorization can obtain the user's basic information when the user is paying attention. The user has no need to do this process. Perception.
The first step is to forward the request through the factory class
/// <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;
}The second step is to write user attention events
WeChat.Messages.TextMessage tm = = em.FromUserName;
tm.FromUserName = em.ToUserName;
tm.CreateTime ==<span style="color: #000000;"> </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> tm.GenerateContent();<br> }</span>
The third step is to obtain the user’s basic information based on the obtained OpenId and accesstoken (the demonstration here is to save the user into In the database)
/// <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; //昵称
sex = root.Element("sex").Value; //性别什么
headimgurl = root.Element("headimgurl").Value; //头像url
province = root.Element("province").Value;//地区
country = root.Element("country").Value;
language = root.Element("language").Value;
subscribe_time = root.Element("subscribe_time").Value;
DateTime create_time = Common.GetTime(subscribe_time);//将时间戳转换为当前时间
city = root.Element("city").Value;
user.OpenID = FromUserName;//OpenID即粉丝ID
user.PublicId = ToUserName;
user.UserID = FromUserName;
user.NickName = nickname;
user.Sex = int.Parse(sex);
user.Subscribe = int.Parse(subscribe);
user.Country = country;
user.Province = province;
user.City = city;
user.CreateDate = create_time;
user.HeadimgUrl = headimgurl;
//将user实体存入数据库中
bool show = _user.Add(user);
#endregion
}
}
catch
{
throw (new ArgumentNullException());
}
}To implement AccessToken in the above code, just create a new Context class
private static DateTime GetAccessToken_Time;

GetData的实现
public static string GetData(string url)
{ return SendGetHttpRequest(url, "application/x-www-form-urlencoded");
}
ParseJson的实现
public static XDocument ParseJson(string json, string rootName)
{ return JsonConvert.DeserializeXNode(json, rootName);
}

Webpage authorization process

The first step is to determine whether the user is authorized. If not authorized, jump to the authorization page. If authorized, obtain basic information
