.Net HttpClient 模拟登录微信公众平台发送消息
1.模拟登录
public WeiXinRetInfo ExecLogin(string name, string pass)
{
CookieContainer cc = new CookieContainer();//接收缓存
WeiXinRetInfo retinfo = null; try
{
string password = Common.GetMd5Str32(pass).ToUpper(); HttpClientHandler hchandler = new HttpClientHandler()
{
CookieContainer = cc
}; HttpClient hclient = new HttpClient(hchandler);
hclient.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.89 Safari/537.36");
hclient.DefaultRequestHeaders.Add("Referer", "https://mp.weixin.qq.com");
//hclient.DefaultRequestHeaders.Add("Host", "mp.weixin.qq.com");
//hclient.DefaultRequestHeaders.Add("ContentType", "application/x-www-form-urlencoded");
//hclient.DefaultRequestHeaders.ExpectContinue = false; HttpContent hcontent = new FormUrlEncodedContent(new Dictionary<string, string>()
{
{"username",name},
{"pwd",password},
{"imgcode",""},
{"f","json"}
}); //https://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN
HttpResponseMessage hresponse = hclient.PostAsync(Wx_Const.LOGIN_URL, hcontent).Result; hresponse.EnsureSuccessStatusCode(); string str_response = hresponse.Content.ReadAsStringAsync().Result; retinfo = Newtonsoft.Json.JsonConvert.DeserializeObject<WeiXinRetInfo>(str_response); if (retinfo.base_resp.err_msg.Equals("ok"))
{
string token = retinfo.redirect_url.Split(new char[] { '&' })[].Split(new char[] { '=' })[].ToString();//取得令牌
lgin.CreateDate = DateTime.Now;
lgin.Token = token; string[] strCookies = (string[])hresponse.Headers.GetValues("Set-Cookie");
HttpClientCookies hcckis = new HttpClientCookies();
hcckis.AddCookie(strCookies);
lgin.hcckis = hcckis; lgin.LoginCookie = cc;
}
}
catch (Exception ex)
{
Console.WriteLine(string.Format("ExecLogin Exception[{0}]", ex.Message));
//throw;
} return retinfo;
}
2.新增图文消息（返回msgid）,后续发送图文消息是用到
/// <summary>
/// 新增图文消息
/// </summary>
/// <returns></returns>
public CreateMsgRs AddWeixinImgTextMsg()
{
string str_url_add_appmsg = string.Format("https://mp.weixin.qq.com/cgi-bin/operate_appmsg?t=ajax-response&sub=create&type=10&token={0}&lang=zh_CN", this.lgif.Token); //https://mp.weixin.qq.com/cgi-bin/operate_appmsg?t=ajax-response&sub=create&type=10&token={0}&lang=zh_CN HttpClientHandler httpClientHandler = new HttpClientHandler()
{

}; HttpClient client = new HttpClient(httpClientHandler); client.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.89 Safari/537.36"); client.DefaultRequestHeaders.Add("Origin", "https://mp.weixin.qq.com"); client.DefaultRequestHeaders.Add("Referer", string.Format("https://mp.weixin.qq.com/cgi-bin/appmsg?t=media/appmsg_edit&action=edit&type=10&lang=zh_CN&token={0}", this.lgif.Token));
//
//client.DefaultRequestHeaders.Add("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8"); //client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded")); //client.DefaultRequestHeaders.ty string fileid0 = ""; UploadImgRs uploadImgRs = AddImg(); if (uploadImgRs.base_resp.ErrMsg.Equals("ok"))
{
fileid0 = uploadImgRs.content;
} HttpContent content = new FormUrlEncodedContent(new Dictionary<string, string>()
{
{"token",this.lgif.Token},
{"lang","zh_CN"},
{"f","json"},
{"ajax",""},
{"random","0.9338385944720358"},

{"title0","张静初出演电影版《三体》 获小说作者肯定"},
{"content0","2015年，被媒体称为中国“科幻元年”，多部科幻片启动了拍摄计划，《三体》当然是最受瞩目的，宣布的开机消息如是说“影片由小说原作者刘慈欣出任监制、游族影业CEO孔二狗担任总制片人、新锐导演张番番历经三年苦心筹备出任影片导演，台前众多国内实力派艺人担纲出演，幕后则由国际团队承担起拍摄、特效等重任，力求将本片打造成一部制作精良、高度还原的史诗级国产科幻片开山之作。”看着这依然模棱两可的说辞，网友们忧心忡忡，去年一片“求不渣”的请求声再起"},
{"digest0","2015年，被媒体称为中国“科幻元年”，多部科幻片启动了拍摄计划，《三体》当然是最受瞩目的"},

string s = response.Content.ReadAsStringAsync().Result; CreateMsgRs cmrs = Newtonsoft.Json.JsonConvert.DeserializeObject<CreateMsgRs>(s); return cmrs;
}
3.获取图文列表
/// <summary>
/// 获取图文消息列表
/// </summary>
/// <returns></returns>
public WeixinImgTextMsg GetImgTextList()
{
WeixinImgTextMsg wxImgText = null; string str_url_get_list = string.Format("https://mp.weixin.qq.com/cgi-bin/appmsg?type=10&action=list&begin=0&count=10&f=json&token={0}&lang=zh_CN&token={0}&lang=zh_CN&f=json&ajax=1&random={1}", this.lgif.Token, "0.18148761289194222"); HttpClientHandler httpClientHandler = new HttpClientHandler()
{

}; HttpClient client = new HttpClient(httpClientHandler); client.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.89 Safari/537.36"); HttpResponseMessage response = client.GetAsync(str_url_get_list).Result; string s = response.Content.ReadAsStringAsync().Result; wxImgText = Newtonsoft.Json.JsonConvert.DeserializeObject<WeixinImgTextMsg>(s); return wxImgText; }
4.获取订阅用户
/// <summary>
/// 获取fakeid
/// </summary>
/// <returns></returns>
public ArrayList SubscribeMP()
{
string token = this.loginInfo.Token; string str_url_sendmsg = string.Format("https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize=10&pageidx=0&type=0&groupid=0&token={0}&lang=zh_CN", token); try

fackID1.Add(fackID);
} return fackID1;
}
catch (Exception ex)
{
throw new Exception(ex.StackTrace);
}
}
5.发送消息
/// <summary>
/// 发送消息
/// </summary>
/// <param name="Message"></param>
/// <param name="fakeid"></param>
public SendMsgRs SendWxMessage(Wx_MsgType WxMsgType, string Message, string fakeid, string msgIdOrFileId)
{
