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"; else this.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('$'); Thread.Sleep(10); foreach (string city in cityData) { string theC = city.Split(',')[1].Trim(); // 城市id int cid = GetNewId("City"); string AreaCode = null; // 获取区数据 string[] districtData = WebRequestHelper.HttpGet(GetDistrictDataUrl(theP, theC), "", Encoding.UTF8).Split('$'); Thread.Sleep(10); foreach (string district in districtData) { string theD = district.Split(',')[1].Trim(); // 区id int 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"; else this.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"; else this.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：
本公司项目中还需要大学数据，那是09年开发大学SNS网站的老数据了，把数据都放进数据库：
需要抽取省、市、区数据的朋友可以下载程序源码来使用：
