很多人可能用过如下的功能:
我向微信号发个字符,然后后台去解析字符,拆出其中的关键字,然后去数据库查询是否开启此项服务,如果服务开启,则返回给用户调用此服务的结果。
最近两天开始做的服务有,天气查询,日历,快递,火车,黄金。。。等六个服务做成接口,今天要分析的是这里面唯一没有调用外部API接口的服务。
首先,我们要写好一个计算农历的方法,:
#region 获取农历方法 ///<summary> /// 实例化一个 ChineseLunisolarCalendar ///</summary> private static ChineseLunisolarCalendar ChineseCalendar = new ChineseLunisolarCalendar(); ///<summary> /// 十天干 ///</summary> private static string[] tg = { "甲", "乙", "丙", "丁", "戊", "己", "庚", "辛", "壬", "癸" }; ///<summary> /// 十二地支 ///</summary> private static string[] dz = { "子", "丑", "寅", "卯", "辰", "巳", "午", "未", "申", "酉", "戌", "亥" }; ///<summary> /// 十二生肖 ///</summary> private static string[] sx = { "鼠", "牛", "虎", "免", "龙", "蛇", "马", "羊", "猴", "鸡", "狗", "猪" }; ///<summary> /// 返回农历天干地支年 ///</summary> ///<param name="year">农历年</param> ///<return s></return s> public static string GetLunisolarYear(int year) { if (year > 3) { int tgIndex = (year - 4) % 10; int dzIndex = (year - 4) % 12; return string.Concat(tg[tgIndex], dz[dzIndex], "[", sx[dzIndex], "]"); } throw new ArgumentOutOfRangeException("无效的年份!"); } ///<summary> /// 农历月 ///</summary> ///<return s></return s> private static string[] months = { "正", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二(腊)" }; ///<summary> /// 农历日 ///</summary> private static string[] days1 = { "初", "十", "廿", "三" }; ///<summary> /// 农历日 ///</summary> private static string[] days = { "一", "二", "三", "四", "五", "六", "七", "八", "九", "十" }; ///<summary> /// 返回农历月 ///</summary> ///<param name="month">月份</param> ///<return s></return s> public static string GetLunisolarMonth(int month) { if (month < 13 && month > 0) { return months[month - 1]; } throw new ArgumentOutOfRangeException("无效的月份!"); } ///<summary> /// 返回农历日 ///</summary> ///<param name="day">天</param> ///<return s></return s> public static string GetLunisolarDay(int day) { if (day > 0 && day < 32) { if (day != 20 && day != 30) { return string.Concat(days1[(day - 1) / 10], days[(day - 1) % 10]); } else { return string.Concat(days[(day - 1) / 10], days1[1]); } } throw new ArgumentOutOfRangeException("无效的日!"); } ///<summary> /// 根据公历获取农历日期 ///</summary> ///<param name="datetime">公历日期</param> ///<return s></return s> public static string GetChineseDateTime(DateTime datetime) { int year = ChineseCalendar.GetYear(datetime); int month = ChineseCalendar.GetMonth(datetime); int day = ChineseCalendar.GetDayOfMonth(datetime); //获取闰月, 0 则表示没有闰月 int leapMonth = ChineseCalendar.GetLeapMonth(year); bool isleap = false; if (leapMonth > 0) { if (leapMonth == month) { //闰月 isleap = true; month--; } else if (month > leapMonth) { month--; } } return string.Concat(GetLunisolarYear(year), "年", isleap ? "闰" : string.Empty, GetLunisolarMonth(month), "月", GetLunisolarDay(day)); } #endregion
接着,拼接好返回的字符:
Console.Write(DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss") + "\r\n" + "农历为:"+GetChineseDateTime(DateTime.Now));
为了测试外部调用的情况,我们可以这样,一个ajax过来,然后提交到handler里面,handler调用这些接口来测试下。
需要注意的是,
1,拼接好的字符串里面的换行符最好是HTML标签中的<br/>,不使用\n;
2,调用百度等大型开发平台的API接口的时候,对于返回的JSON,处理JSON转对象的时候,要注意JSON里面数组都要变成LIST,然后再调用自己构造的泛型方法去转换。

网上也有很多付费的接口,另外,今天做黄金查询的时候,发现了个聚合数据也不错哟~
