参考文档：https://mp./wiki?t=resource/res_main&id=mp1445241432
一、安装Senparc.Weixin NuGet包。
二、添加引用
using Senparc.CO2NET.Extensions;using Senparc.Weixin.MP.Entities.Request;
三、微信公众号-开发-基本配置
Global.asax全局配置Application_Start
//微信配置开始var isGLobalDebug = true;//设置全局 Debug 状态var senparcSetting = SenparcSetting.BuildFromWebConfig(isGLobalDebug);var register = RegisterService.Start(senparcSetting).UseSenparcGlobal();//CO2NET全局注册，必须！var isWeixinDebug = true;//设置微信 Debug 状态var senparcWeixinSetting = SenparcWeixinSetting.BuildFromWebConfig(isWeixinDebug);register.UseSenparcWeixin(senparcWeixinSetting, senparcSetting);微信全局注册，必须！//注册公众号AccessTokenContainer.Register(System.Configuration.ConfigurationManager.AppSettings["WeixinAppId"],System.Configuration.ConfigurationManager.AppSettings["WeixinAppSecret"],"公众号");//注册小程序（完美兼容）AccessTokenContainer.Register(System.Configuration.ConfigurationManager.AppSettings["WxOpenAppId"],System.Configuration.ConfigurationManager.AppSettings["WxOpenAppSecret"],"小程序");//微信配置结束
/// <summary>/// 微信后台验证地址（使用Get），微信后台的“接口配置信息”的Url填写如：http://sdk./weixin/// </summary>[HttpGet][ActionName("Index")]public ActionResult Get(PostModel postModel, string echostr){if (CheckSignature.Check(postModel.Signature, postModel.Timestamp, postModel.Nonce, Token)){return Content(echostr); //返回随机字符串则表示验证通过}else{return Content("failed:" + postModel.Signature + "," + MP.CheckSignature.GetSignature(postModel.Timestamp, postModel.Nonce, Token) + "。" +"如果你在浏览器中看到这句话，说明此地址可以被作为微信公众账号后台的Url，请注意保持Token一致。");}}
四、获取公众号相关信息
public static readonly string Token = WebConfigurationManager.AppSettings["WeixinToken"];//与微信公众账号后台的Token设置保持一致，区分大小写。public static readonly string EncodingAESKey = WebConfigurationManager.AppSettings["WeixinEncodingAESKey"];//与微信公众账号后台的EncodingAESKey设置保持一致，区分大小写。public static readonly string AppId = WebConfigurationManager.AppSettings["WeixinAppId"];//与微信公众账号后台的AppId设置保持一致，区分大小写。public static readonly string WeixinAppSecret = WebConfigurationManager.AppSettings["WeixinAppSecret"];
五、获取token
public string GetAccessToken(){return Senparc.Weixin.MP.Containers.AccessTokenContainer.GetAccessToken(AppId);}
六、自定义创建菜单
利用json更新菜单
[HttpPost]public string CreateMenuFromJson(string token, string fullJson){//TODO:根据"conditionalmenu"判断自定义菜单var apiName = "使用JSON更新";try{GetMenuResultFull resultFull = Newtonsoft.Json.JsonConvert.DeserializeObject<GetMenuResultFull>(fullJson);//重新整理按钮信息WxJsonResult result = null;IButtonGroupBase buttonGroup = null;buttonGroup = monApi.GetMenuFromJsonResult(resultFull, new ButtonGroup()).menu;result = monApi.CreateMenu(token, buttonGroup);var json = new{Success = result.errmsg == "ok",Message = "菜单更新成功。" + apiName};//return Json(json);return "菜单更新成功。" + apiName;}catch (Exception ex){var json = new { Success = false, Message = string.Format("更新失败：{0}。{1}", ex.Message, apiName) };//return Json(json);return string.Format("更新失败：{0}。{1}", ex.Message, apiName);}}
json格式实例（一级菜单最多三个，二级菜单最多五个）
{"menu": {"button": [{"name": "一级菜单","sub_button": [{"type": "view","name": "二级菜单","url": ""}]}]}}
读取json
public string GetMenuJson(){StreamReader sr = new StreamReader(System.Web.HttpRuntime.AppDomainAppPath + "\\menu.json", Encoding.Default);string line;string jsonobj = "";while ((line = sr.ReadLine()) != null){jsonobj = jsonobj + line.ToString();}return jsonobj;}
创建菜单
public ActionResult CreateMenu(){string MenuJson = GetMenuJson();string token = GetAccessToken();return Content(CreateMenuFromJson(token, MenuJson));}
七、调用授权页面获取用户微信code
urlpath:回调url,此url对应域名需要配置在微信公众号-接口权限-网页服务-网页授权-网页授权获取用户基本信息
public void GetWeixinCode(string urlpath){string state = Guid.NewGuid().ToString("N");string url = string.Format("https://open./connect/oauth2/authorize?appid={0}&redirect_uri={1}&response_type=code&scope=snsapi_userinfo&state=" + state + "#wechat_redirect", AppId, urlpath);Response.Redirect(url);}
八、根据code获取用户openid
post访问地址
public static string WebRequestPostOrGet(string sUrl, string sParam){byte[] bt = System.Text.Encoding.UTF8.GetBytes(sParam);Uri uriurl = new Uri(sUrl);HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(uriurl);req.Method = "Post";req.Timeout = 120 * 1000;req.ContentType = "application/x-www-form-urlencoded;";req.ContentLength = bt.Length;using (Stream reqStream = req.GetRequestStream()){reqStream.Write(bt, 0, bt.Length);reqStream.Flush();}try{using (WebResponse res = req.GetResponse()){Stream resStream = res.GetResponseStream();StreamReader resStreamReader = new StreamReader(resStream, System.Text.Encoding.UTF8);string resLine;System.Text.StringBuilder resStringBuilder = new System.Text.StringBuilder();while ((resLine = resStreamReader.ReadLine()) != null){resStringBuilder.Append(resLine + System.Environment.NewLine);}resStream.Close();resStreamReader.Close();return resStringBuilder.ToString();}}catch (Exception ex){return ex.Message;}}
根据code获取openid
/// <summary>/// 根据code获取用户openid/// </summary>/// <param name="Code"></param>/// <param name="access_token"></param>/// <returns></returns>public string GetOpenidByCode(string Code, out string access_token){string url = string.Format("https://api./sns/oauth2/access_token?appid={0}&secret={1}&code={2}&grant_type=authorization_code", AppId, WeixinAppSecret, Code);string ReText = WebRequestPostOrGet(url, "");//post/get方法获取信息Newtonsoft.Json.Linq.JObject DicText = (Newtonsoft.Json.Linq.JObject)Newtonsoft.Json.JsonConvert.DeserializeObject(ReText);access_token = "";if (DicText.ContainsKey("access_token"))access_token = DicText["access_token"].ToString();if (!DicText.ContainsKey("openid"))return "";return DicText["openid"].ToString();}
九、根据openid获取用户信息
WXModel：
public class WXModel{public string openid { get; set; }public string nickname { get; set; }public int sex { get; set; }public string province { get; set; }public string city { get; set; }public string country { get; set; }public string headimgurl { get; set; }}
获取用户信息
public WXModel GetUserInfoByCode(string code){string access_token = "";string openid = GetOpenidByCode(code, out access_token);string userinfo = WebRequestPostOrGet("https://api./sns/userinfo?access_token=" + access_token + "&openid=" + openid + "&lang=zh_CN", "");WXModel model = Newtonsoft.Json.JsonConvert.DeserializeObject<WXModel>(userinfo);return model;}
十、微网站公用获取用户信息方法
public WXModel GetUser(string urlpath){WXModel model = null;var code = Request.Params["code"];urlpath = urlpath.UrlEncode();if (code == null || code == ""){GetWeixinCode(urlpath);}else{model = GetUserInfoByCode(code);}return model;}
十一、需要获取用户的地方
string urlpath = Request.Url.AbsoluteUri;tb_user user = GetUser(urlpath);
