微信公众号开发网页授权获取用户基本信息

如果用户在微信客户端中访问第三方网页，公众号可以通过微信网页授权机制，来获取用户基本信息，进而实现业务逻辑。
注意：网页授权两种方式
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 ==<span style="color: #000000;"> </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> tm.GenerateContent();<br> }</span>
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; //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());
}
}上面代码中 AccessToken的实现，新建一个Context类即可
private static DateTime GetAccessToken_Time;
/// 631fb227578dfffda61e1fa4d04b7d25
/// 过期时间为7200秒

private static string mAccessToken;
public static string AppID = "换成相应公众号的即可";
public static string AppSecret = "换成相应公众号的即可";
/// 631fb227578dfffda61e1fa4d04b7d25

/// 039f3e95db2a684c7b74365531eb6044
public static string AccessToken
{
get
{
//如果为空，或者过期，需要重新获取
if (string.IsNullOrEmpty(mAccessToken) || HasExpired())
{
//获取access_token
mAccessToken = GetAccessToken(AppID, AppSecret);
}
return mAccessToken;
}
}

private static string GetAccessToken(string appId, string appSecret)
{
string url = string.Format("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}", appId, appSecret);
string result = HttpUtility.GetData(url);
XDocument doc = XmlUtility.ParseJson(result, "root");
XElement root = doc.Root;
if (root != null)
{
XElement access_token = root.Element("access_token");
if (access_token != null)
{
GetAccessToken_Time = DateTime.Now;
if (root.Element("expires_in") != null)
{
Expires_Period = int.Parse(root.Element("expires_in").Value);
}
return access_token.Value;
}
else
{
GetAccessToken_Time = DateTime.MinValue;
}
}
return null;
}
/// 631fb227578dfffda61e1fa4d04b7d25

private static bool HasExpired()
{
if (GetAccessToken_Time != null)
{
//过期时间，允许有一定的误差，一分钟。获取时间消耗
if (DateTime.Now > GetAccessToken_Time.AddSeconds(Expires_Period).AddSeconds(-60))
{
return true;
}
}
return false;
}
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);
}

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
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
/// 631fb227578dfffda61e1fa4d04b7d25
/// 获取授权用户的基本信息,包括头像，姓名，等等(推荐方法） /// 039f3e95db2a684c7b74365531eb6044

/// 2363942ed0d6cd3e85bae1dffa568116f7735d9f6a7af371769ab5c16d23b2f3
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Code GetShouQuanCodeUrl(HttpContext.Current.Request.Url.AbsoluteUri);
} else if(HttpContext.Current.Request.QueryString["code"] == null || HttpContext.Current.Request.QueryString["code"] == "")
{ //用户授权的Code GetShouQuanCodeUrl(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.ToObject40e1c272594a55af5d8f3e794dcde9cb(gethtml); return ac;
} return null;
}
其中，用户授权的code方法如下：
/// 631fb227578dfffda61e1fa4d04b7d25
/// 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） /// 039f3e95db2a684c7b74365531eb6044
/// 0ab5e68b8f5d292e9a5f810a0a5b2929目标Url8bb7487ae6a16a43571bc14c7fcf93c2
/// 2363942ed0d6cd3e85bae1dffa568116f7735d9f6a7af371769ab5c16d23b2f3
public static void GetShouQuanCodeUrl(string url)
{ string CodeUrl = ""; //加密过的url
string value = HttpUtility.UrlEncode(url); //用户授权后的Code
CodeUrl = $"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
/// 631fb227578dfffda61e1fa4d04b7d25
//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）
/// 039f3e95db2a684c7b74365531eb6044
