10分钟采集凡客最新的省、市、区、邮政编码和电话区号（附源码）

　　最近的开发的项目需要用到省、市、区数据，因为要开发的项目也是电子商务网站，在参考凡客的用户体验时，发现它连深圳最新分离出来的光明新区都有了，拍拍网都没有更新数据，看来凡客在数据更新方面还是挺负责的，所以了解了一下它的数据格式，然后花了点时间写了个小程序来抽取最新的省、市、区、邮政编码和电话区号，邮政编码和电话区号是在用户选择数据后推荐给用户选择的，免得用户再花时间去查，如下界面：

一共有三个地址是返回数据的：

        private string GetCityDataUrl(string province){string url = "http://my.vancl.com/DeliveryAddress/GetCityData?povinceId={0}&r={1}";return string.Format(url, JScriptUtil.Escape(province), GetRandom());}private string GetDistrictDataUrl(string province, string city){string url = "http://my.vancl.com/DeliveryAddress/GetAreaData?cityId={0}&povinceId={1}&r={2}";return string.Format(url, JScriptUtil.Escape(city), JScriptUtil.Escape(province), GetRandom());}private string GetPostCodeUrl(string province, string city, string district){string url = "http://my.vancl.com/DeliveryAddress/GetPostalCode?povince={0}&city={1}&area={2}&r={3}";return string.Format(url, Utils.UrlEncode(province), Utils.UrlEncode(city), Utils.UrlEncode(district), GetRandom());}

核心函数：

        // 抽取凡客数据private void DoGetVanclData(){string[] provinces = Util.Provinces.Split('|');for (int i = 0; i < provinces.Length; i++){string theP = provinces[i].Trim();this.Invoke(new MethodInvoker(() =>{this.label1.Text = theP + "...";}));// 增加省份int pid = GetNewId("Province");this.Invoke(new MethodInvoker(() =>{if (pid == 1)this.textBox1.Text += "insert into [Db_MoMoMate].[dbo].[Province]([Id],[Name])\r\nSELECT " + pid.ToString() + ", '" + theP + "'\r\n";elsethis.textBox1.Text += "union\r\nSELECT " + pid.ToString() + ", '" + theP + "'\r\n";}));// 获取城市数据string[] cityData = WebRequestHelper.HttpGet(GetCityDataUrl(theP), "", Encoding.UTF8).Split('$');Thread.Sleep(10);foreach (string city in cityData){string theC = city.Split(',')[1].Trim();// 城市idint cid = GetNewId("City");string AreaCode = null;// 获取区数据string[] districtData = WebRequestHelper.HttpGet(GetDistrictDataUrl(theP, theC), "", Encoding.UTF8).Split('$');Thread.Sleep(10);foreach (string district in districtData){string theD = district.Split(',')[1].Trim();// 区idint did = GetNewId("District");string[] postData = WebRequestHelper.HttpGet(GetPostCodeUrl(theP, theC, theD), "", Encoding.UTF8).Split('$');if (AreaCode == null){AreaCode = postData[4];}string postCode = postData[3];Thread.Sleep(10);// 增加区this.Invoke(new MethodInvoker(() =>{if (did == 1)this.textBox3.Text += "insert into [Db_MoMoMate].[dbo].[District]([Id],[CityId],[Name],[PostCode])\r\nSELECT " + did.ToString() + ", " + cid.ToString() + ", '" + theD + "', '" + postCode + "'\r\n";elsethis.textBox3.Text += "union\r\nSELECT " + did.ToString() + ", " + cid.ToString() + ", '" + theD + "', '" + postCode + "'\r\n";}));}// 增加城市this.Invoke(new MethodInvoker(() =>{if (cid == 1)this.textBox2.Text += "insert into [Db_MoMoMate].[dbo].[City]([Id],[ProvinceId],[Name],[AreaCode])\r\nSELECT " + cid.ToString() + ", " + pid.ToString() + ", '" + theC + "', '" + AreaCode + "'\r\n";elsethis.textBox2.Text += "union\r\nSELECT " + cid.ToString() + ", " + pid.ToString() + ", '" + theC + "', '" + AreaCode + "'\r\n";}));}this.Invoke(new MethodInvoker(() =>{if (i == provinces.Length - 1){this.label1.Text = "done";this.button1.Enabled = true;}}));}}

最终运行效果如下：
