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）-优快云博客

　　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：
