web服务:
添加方法:
[WebMethod]//必须有
public int Add(int a,int b)
{
returna+b;
}
public Data GetStudent()
{
string str=System.ConigurationManager.
using(SqlConnection cnn=new SqlConnection())
{
using(SqlCommand cmm=cnn.CreateCommand())
{
cmm.CommandText="select*from student";
SqlDataAdapter da =new SqlDataAdapter(cmm);
DataSet ds =new DataSet();
da.Fill(ds);
return ds;
}
}
}
web服务的传输协议知识点:
HTTP-GET
在地址栏
<webService><protocols><add name="HttpGet"></protocols></webService>
HTTP-POST
SOAP
将WebService发布到服务器上:
调用上述加法(新建网站)(没有发布必须打开需要调用的网站)
protected void Button1_Click(object sender, EventArgs e)
{
localhost.WebService ws=new localhost.WebService();
this.TextBox3.Text = ws.Add(Convert.ToInt32(TextBox1.Text), Convert.ToInt32(TextBox2.Text)).ToString();
this.GridView1.DataSource=ws.GetStudent();
this.GridView1.DataBind();
}
天气预报:
protected void Page_Load(object sender, EventArgs e)
{
if(!this.IsPostBack)
{
cn.com.webxml.www.WeatherWebService wws=new cn.com.webxml.www.WeatherWebService();
this.DropDownList1.DataSource=wws.getSupportProvince();
this.DropDownList1.DataBind();
}
}
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
cn.com.webxml.www.WeatherWebService wws = new cn.com.webxml.www.WeatherWebService();
BindCity(wws);
}
private void BindCity(cn.com.webxml.www.WeatherWebService wws)
{
this.DropDownList2.Items.Clear();
string[] strs = wws.getSupportCity(this.DropDownList1.SelectedValue);
foreach (string str in strs)
{
this.DropDownList2.Items.Add(new ListItem(str.Substring(0, str.IndexOf("("))));
}
}
protected void Button2_Click(object sender, EventArgs e)
{
cn.com.webxml.www.WeatherWebService wws = new cn.com.webxml.www.WeatherWebService();
string[] strs = wws.getWeatherbyCityName(this.DropDownList2.SelectedValue);
this.Label1.Text = strs[0] + "," + strs[1] + "<br/>";
this.Label1.Text = "温度:" + strs[5] + "<br/>";
this.Label1.Text = "风:" + strs[7];
}
电话号码的查询:
protected void Button3_Click(object sender, EventArgs e)
{
cn.com.webxml.webservice.MobileCodeWS ws=new cn.com.webxml.webservice.MobileCodeWS ();
string strss = ws.getMobileCodeInfo(this.TextBox4.Text, this.TextBox5.Text);
this.Label2.Text = strss;
}
