概述

最近在整一个微信扫码用户帐号绑定功能。为了满足用户帐号绑定场景的需要，通过生成用户自己的二维码，用户扫描后，公众号可以接收到事件推送。

如下

1、用户登录扫码

2、绑定成功

实现思路

扫码绑定账户，其实就是扫描带有用户信息的二维码，微信端接收到消息，会向服务器推送一个扫描事件，服务端接收到信息，进行处理，进而在界面进行信息反馈。

用户登录系统=》生成带有用户id的二维码=》用户打开微信扫码=》

微信服务器向我们的系统回调扫描事件=》得到扫描的用户id+openid=>

进行绑定操作=》进而把结果反映到界面

主要代码实现

1、获取二维码 

string domain = BqoolWebSite.WebSiteMapping[BqoolWebSiteType.BigCRMWebService][CommonSetting.GetEnvironmentMode()];string url = domain + "/api/WeChat/GetQrCode";var data = new GetQrCodeParam(){Account = "xxxxx", //AccountUser_ID = "xxxxx",//User_IDDate = DateTime.UtcNow.ToUnixTimestamp(),Action = BaseRequestParam.ActionType.Get,IsRefresh = false //是否强制刷新 默认false};_nLogger.Info($"WeChat GetQrCode Call BigCRM Web - Url : {url}, data : {data.ToJsonString()}");var result = HttpTools.EncryptPost<GetQrCodeParam, ApiResult>(url, data);_nLogger.Info($"WeChat GetQrCode Call BigCRM Web Result - Url : {url}, result : {result.ToJsonString()}");
if (result.Success && result.Data != null){//  result.Data   GetQrCodeResult}

2、获取绑定信息  

string domain = BqoolWebSite.WebSiteMapping[BqoolWebSiteType.BigCRMWebService][CommonSetting.GetEnvironmentMode()];string url = domain + "/api/WeChat/GetBindInfo";var data = new GetBindInfoParam(){Account = "xxxxx", //AccountUser_ID = "xxxxxx",//User_IDDate = DateTime.UtcNow.ToUnixTimestamp(),Action = BaseRequestParam.ActionType.Get};_nLogger.Info($"WeChat GetBindInfo Call BigCRM Web - Url : {url}, data : {data.ToJsonString()}");var result = HttpTools.EncryptPost<GetBindInfoParam, ApiResult>(url, data);_nLogger.Info($"WeChat GetBindInfo Call BigCRM Web Result - Url : {url}, result : {result.ToJsonString()}");if (result.Success && result.Data != null){//  result.Data   GetBindInfoResult}

3、取消订阅  

string domain = BqoolWebSite.WebSiteMapping[BqoolWebSiteType.BigCRMWebService][CommonSetting.GetEnvironmentMode()];string url = domain + "/api/WeChat/Disconnect";var data = new GetBindInfoParam (){Account = "xxxx", //AccountUser_ID = "xxxxx",//User_IDDate = DateTime.UtcNow.ToUnixTimestamp(),Action = BaseRequestParam.ActionType.Update};_nLogger.Info($"WeChat Disconnect Call BigCRM Web - Url : {url}, data : {data.ToJsonString()}");var result = HttpTools.EncryptPost< GetBindInfoParam, ApiResult>(url, data);_nLogger.Info($"WeChat Disconnect Call BigCRM Web Result - Url : {url}, result : {result.ToJsonString()}");if (result.Success ){//ApiResult}
