小小积累,天气预报~

今天看到公司的一个原来的网站天气预报的那个web服务好像死了,然后就抽时间自己看了下,别看这个功能貌似简单,但是对于我来说,却也弯弯绕了下,不管怎么说,也算是一种积累。废话不多说,代码:

前台:


<head runat="server">    <title>天气预报~</title></head><body>    <form id="form1" runat="server">    地名: <asp:TextBox ID="TB_DIMING" Text="北京" runat="server"></asp:TextBox>    <asp:Button ID="Btn_Tijiao" runat="server" Text="提交" OnClick="Btn_Tijiao_Click" />    <div style="width: 300px; height: 110px; border: 1px solide #ccc">        <table style="width: 100%; height: 80px;">            <tr>                <td style="width: 30%;">                    <table>                        <tr>                            <td>                                <asp:Literal ID="Literal1" runat="server"></asp:Literal>                            </td>                        </tr>                        <tr>                            <td>                                <b><asp:Literal ID="Literal2" runat="server"></asp:Literal></b>                            </td>                        </tr>                    </table>                </td>                <td>                    <table>                        <tr>                            <td>                                <b>温度:</b><asp:Literal ID="Literal3" runat="server"></asp:Literal>                            </td>                        </tr>                        <tr>                            <td>                                <b>风力:</b><asp:Literal ID="Literal4" runat="server"></asp:Literal>                            </td>                        </tr>                        <tr>                            <td>                                <b>空气质量:</b><asp:Literal ID="Literal5" runat="server"></asp:Literal>                            </td>                        </tr>                    </table>                </td>            </tr>        </table>    </div>    </form></body>

前台页面挺糙的,这个我知道,主要是说这个功能实现的过程:

后台:


PRotected void Page_Load(object sender, EventArgs e)    {        if (!IsPostBack)        {            disp_weather("北京");        }    }    public void Btn_Tijiao_Click(object sender, EventArgs e)    {        string diming = TB_DIMING.Text.Trim();        if (diming != "")            disp_weather(diming);    }private void disp_weather(string city)    {        try        {            string[] arrAy = null;            ArrayList weather = Bnn_Weather.Get_3day_weather(city);            if (weather.Count > 0)            {                DateTime dt = Convert.ToDateTime(weather[3].ToString());                Literal5.Text = weather[5].ToString().Replace("空气质量:", "");                arrAy = weather[7].ToString().Split(' ');                Literal2.Text = arrAy[1].ToString();                Literal3.Text = weather[8].ToString();                Literal4.Text = weather[9].ToString();                if (weather[10].ToString() == weather[11].ToString())                {                    Literal1.Text = "<img src=/"../App_Themes/tqimg/b_" + weather[10].ToString() + "/" width=/"50/" height=/"46/" alt='" + arrAy[0].ToString() + "" + weather[1].ToString() + "天气预报:" + arrAy[1].ToString() + "' />";                }                else                {                    Literal1.Text = "<img src=/"../App_Themes/tqimg/b_" + weather[10].ToString() + "/" width=/"50/" height=/"46/" alt='" + arrAy[0].ToString() + "" + weather[1].ToString() + "天气预报:" + arrAy[1].ToString() + "'/><img src=/"../App_Themes/tqimg/b_" + weather[11].ToString() + "/" width=/"50/" height=/"46/" alt='" + arrAy[1].ToString().Split('转')[1].ToString() + "'/>";                }            }        }        catch (Exception)        {            Page.ClientScript.RegisterClientScriptBlock(GetType(), "asdf", "<script>alert('您提供的城市查不到')</script>");        }    }    public class Bnn_Weather    {        public static ArrayList Get_3day_weather(string CityName)        {            try            {                //接口地址:http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx                WeatherWS wc = new WeatherWS();                string[] strarr = wc.getWeather(CityName, "");                ArrayList list = new ArrayList();                int listLength = strarr.Length;                if (listLength > 0)                {                    for (int i = 0; i < listLength; i++)                    {                        list.Add(strarr[i]);                    }                }                return list;            }            catch (Exception e)            {                throw;            }        }    }

之前百度了个例子是在工程里添加一个WebService,后来同事告我一个方法就是通过VS2010中的命令提示工具:WSDL http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx 然后会在本地输出一个类文件,其实性质是一样的,只是我不知道。

慢慢积累….

对了,还有就是附加上这个里面需要的天气图片:
