webservice教程(怎么在http中利用webservice對httprequest和httpresponse進行操作)

客戶端:

// 創建一個DataTable

DataTable data = new DataTable("Project");

data.Columns.Add("Name");

data.Columns.Add("Birthday");

data.Rows.Add(new object[] { "Wendy", "1978/03/11" });

data.Rows.Add(new object[] { "Philip", "2000/11/05" });

data.Rows.Add(new object[] { "Felix", "1999/08/04" });

using (var ms = new MemoryStream())

{

// 將DataTable用Xml格式寫入流

data.WriteXml(ms, XmlWriteMode.WriteSchema);

var client = new WebClient();

// 定義HttpRequest的Content-Type(xml,json等)

client.Headers.Add("Content-Type", "text/xml");

var url = "http://localhost:2609/Service1.asmx/SendXml";

// Send HttpRequest

var resp = client.UploadData(url, "POST", ms.ToArray());

var strResp = System.Text.Encoding.UTF8.GetString(resp);

MessageBox.Show(strResp);

}

服務端:

復制代碼 代碼如下:

[WebMethod]

public void SendXml()

{

// 獲得客戶端RAW HttpRequest

var inputStream = HttpContext.Current.Request.InputStream;

// 定義Response返回的格式是:Json

var response = HttpContext.Current.Response;

response.ContentType = "text/json";

//var strXml = "";

//using (var sr = new StreamReader(inputStream))

// strXml = sr.ReadToEnd();

try

{

DataTable data = new DataTable();

using (var xr = XmlReader.Create(inputStream))

data.ReadXml(xr);

// 將讀入Xml的DataTable的行數返回客戶端

string count = "/"" + data.Rows.Count + "/"";

response.BinaryWrite(System.Text.Encoding.UTF8.GetBytes(count));

}

catch (Exception ex)

{

response.BinaryWrite(System.Text.Encoding.UTF8.GetBytes(ex.Message));

}

}

客戶端輸出""3""
