asp.net微信开发已关注用户管理步骤详解

这篇文章主要介绍了asp.net微信开发中有关已关注用户管理的相关内容，需要的朋友可以参考下
公众号可通过本接口来获取帐号的关注者列表，关注者列表由一串openid（加密后的微信号，每个用户对每个公众号的openid是唯一的）组成。一次拉取调用最多拉取10000个关注者的openid，可以通过多次拉取的方式来满足需求。
接口调用请求说明
http请求方式: get（请使用https协议）
返回说明
正确时返回json数据包：
错误时返回json数据包（示例为无效appid错误）：
{errcode:40013,errmsg:invalid appid}
附：关注者数量超过10000时
当公众号关注者数量超过10000时，可通过填写next_openid的值，从而多次拉取列表的方式来满足需求。
具体而言，就是在调用接口时，将上一次调用得到的返回中的next_openid值，作为下一次调用中的next_openid值。
示例如下：
公众账号a拥有23000个关注的人，想通过拉取关注接口获取所有关注的人，那么分别请求url如下：
https://api.weixin.qq.com/cgi-bin/user/get?access_token=access_token
返回结果:
{ "total":23000, "count":10000, "data":{" openid":[ "openid1", "openid2", ..., "openid10000" ] }, "next_openid":"openid10000" }
https://api.weixin.qq.com/cgi-bin/user/get?access_token=access_token&next_openid=next_openid1
返回结果:
{ "total":23000, "count":10000, "data":{ "openid":[ "openid10001", "openid10002", ..., "openid20000" ] }, "next_openid":"openid20000" }
https://api.weixin.qq.com/cgi-bin/user/get?access_token=access_token&next_openid=next_openid2
返回结果（关注者列表已返回完时，返回next_openid为空）:
{ "total":23000, "count":3000, "data":{" "openid":[ "openid20001", "openid20002", ..., "openid23000" ] }, "next_openid":"openid23000" }
微信官方网站后台的接口权限表里（以服务号为例）每天调用的获取用户列表能获取500次，获取用户基本信息可以获取500000次，所以说接下来，我在获取用户列表的时候，会用到缓存，别看500次不少了，
可是真正的用起来快得不得了，先上效果图如下：
先来看看用户列表，官网说获取用户的列表返回的是一组组openid，针对这个特性，我是这么做的，
创建一个用于存储openid的类
public class wxopenidinfo { public string wxopenid { get; set; }//用户存放微信用户的openid }
然后再创建用户信息的基本类
/// <summary> /// 微信用户基本信息类 /// </summary> public class wxuserinfo { public int subscribe { get; set; }//关注状态 public string openid { get; set; }//openid public string nickname { get; set; }//昵称 public string sex { get; set; }//性别 public string city { get; set; }//城市 public string province { get; set; }//省份 public string headimgurl { get; set; }//头像图片地址 public string subscribe_time { get; set; }//关注时间 public string remark { get; set; }//备注 public string groupid { get; set; }//分组id }

分组统计，用于显示每个分组的已存在人数，无其他作用

weixinserver wxs = new weixinserver();是单独创建的一个类，主要用来获取通行证和加载流的方法，代码如下：
/// <summary> /// 微信服务类 /// </summary> public class weixinserver { /// <summary> /// 获取通行证 /// </summary> /// <returns></returns> public string getaccesstoken() { string url_token = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=此处应该填写公众的appid&secret=此处应该填写公众号的secret"; httpwebrequest myrequest = (httpwebrequest)webrequest.create(url_token); myrequest.method = "get"; httpwebresponse myresponse = (httpwebresponse)myrequest.getresponse(); streamreader reader = new streamreader(myresponse.getresponsestream(), encoding.utf8); string content = reader.readtoend(); reader.close(); return content; } public string getpage(string p, string postdata) { stream outstream = null; stream instream = null; streamreader sr = null; httpwebresponse response = null; httpwebrequest request = null; encoding encoding = encoding.utf8; byte[] data = encoding.getbytes(postdata); // 准备请求... try { // 设置参数 request = webrequest.create(p) as httpwebrequest; cookiecontainer cookiecontainer = new cookiecontainer(); request.cookiecontainer = cookiecontainer; request.allowautoredirect = true; request.method = "post"; request.contenttype = "application/x-www-form-urlencoded"; request.contentlength = data.length; outstream = request.getrequeststream(); outstream.write(data, 0, data.length); outstream.close(); //发送请求并获取相应回应数据 response = request.getresponse() as httpwebresponse; //直到request.getresponse()程序才开始向目标网页发送post请求 instream = response.getresponsestream(); sr = new streamreader(instream, encoding); //返回结果网页（html）代码 string content = sr.readtoend(); string err = string.empty; return content; } catch (exception ex) { string err = ex.message; return string.empty; } } }
