1.设置JS安全域名

2.开通微信支付，并在商户端设置支付安全域名

3.获取JSAPI权限参数

///         /// jsapi获取签名        /// 
        private config QuerySignature(string access_token,string ticket,string ticket_time,int weixin_id,string appid)        {            //需要签名的页面的url            string urlstr = Util.getServerPath() + "/Home/TemplateView";            //获取最新的jsapi_tiket与accesstoken            WeixinJsAPI jsAPi = new WeixinJsAPI(access_token, ticket, ticket_time, weixin_id);            string jsapi = jsAPi.Ticket;            //取签名的时间戳可以是随机数            long timestamp = Util.getLongTime();            //随机字符串(可以写方法随机生成)            string nonceStr = sys.getRandomCode(26);            //签名算法            string signature = GetSignature(jsapi, nonceStr, timestamp, urlstr);            return new config() {appId= appid,nonceStr= nonceStr,timestamp= timestamp,signature= signature };         }

///         /// 签名算法        /// 
        /// ticket        /// 随机字符串        /// 时间戳        /// 需要签名的url        private string GetSignature(string jsapi, string nonceStr, long timestamp, string urlstr)        {            StringBuilder str = new StringBuilder();            string string1 = "jsapi_ticket=" + jsapi + "&noncestr=" + nonceStr + "&timestamp=" + timestamp + "&url=" + urlstr;            return FormsAuthentication.HashPasswordForStoringInConfigFile(string1, "SHA1").ToLower();        }

/*产生验证码*/        public static string getRandomCode(int codeLength)        {            string so = "2,3,5,6,7,8,9,A,B,C,D,E";            string[] strArr = so.Split(',');            string code = "";            Random rand = new Random();            for (int i = 0; i < codeLength; i++)            {                code += strArr[rand.Next(0, strArr.Length)];            }            return code;        }

　　还需要获取微信公众号的JSAPI的ticket

4.统一下单
