C#下的webservcie 实现代码和在vc和python下的调用实现（原创）

C#下的webservcie 实现代码,很简单一看就清楚了是完成什么样的功能了

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Web;
using System.Web.Services;

namespace WebHelloZ5
{
///

1<summary>   
2/// Service1 的摘要说明。   
3/// </summary>

public class Service1 : System.Web.Services.WebService
{
public Service1()
{
//CODEGEN：该调用是 ASP.NET Web 服务设计器所必需的
InitializeComponent();
}

#region Component Designer generated code

//Web 服务设计器所必需的
private IContainer components = null;

///

1<summary>   
2/// 设计器支持所需的方法 - 不要使用代码编辑器修改   
3/// 此方法的内容。   
4/// </summary>

private void InitializeComponent()
{
}

///

1<summary>   
2/// 清理所有正在使用的资源。   
3/// </summary>

protected override void Dispose( bool disposing )
{
if(disposing && components != null)
{
components.Dispose();
}
base.Dispose(disposing);
}

#endregion

// WEB 服务示例
// HelloWorld() 示例服务返回字符串 Hello World
// 若要生成，请取消注释下列行，然后保存并生成项目
// 若要测试此 Web 服务，请按 F5 键

//[WebMethod]
//public string HelloWorld1()
//{
// return "Hello World";
//}

[WebMethod]
public string HelloWorld(int nArg, string strArg)
{
return strArg+ nArg.ToString();
}

}
}

下面就是调用webservice时,网络上大家发送的数据包了

Client请求数据:

POST /WebHelloZ5/Service1.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml
Content-Length: length
SOAPAction: " http://tempuri.org/HelloWorld "

1<soap:envelope xmlns:soap="  http://schemas.xmlsoap.org/soap/envelope/  " xmlns:xsd="  http://www.w3.org/2001/XMLSchema  " xmlns:xsi="  http://www.w3.org/2001/XMLSchema-instance  ">
2<soap:body>
3<helloworld xmlns="  http://tempuri.org/  ">
4<narg>int</narg>
5<strarg>string</strarg>
6</helloworld>
7</soap:body>
8</soap:envelope>

Server回应数据:

HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

1<soap:envelope xmlns:soap="  http://schemas.xmlsoap.org/soap/envelope/  " xmlns:xsd="  http://www.w3.org/2001/XMLSchema  " xmlns:xsi="  http://www.w3.org/2001/XMLSchema-instance  ">
2<soap:body>
3<helloworldresponse xmlns="  http://tempuri.org/  ">
4<helloworldresult>string</helloworldresult>
5</helloworldresponse>
6</soap:body>
7</soap:envelope>

VC7下的自动生成的代理类,如下所示:

template

  1<typename tclient="">   
  2inline HRESULT CService1T<tclient>::HelloWorld(   
  3int nArg,   
  4BSTR strArg,   
  5BSTR* HelloWorldResult   
  6)   
  7{   
  8HRESULT __atlsoap_hr = InitializeSOAP(NULL);   
  9if (FAILED(__atlsoap_hr))   
 10{   
 11SetClientError(SOAPCLIENT_INITIALIZE_ERROR);   
 12return __atlsoap_hr;   
 13}   
 14  
 15CleanupClient(); 
 16
 17CComPtr<istream> __atlsoap_spReadStream;   
 18__CService1_HelloWorld_struct __params;   
 19memset(&amp;__params, 0x00, sizeof(__params));   
 20__params.nArg = nArg;   
 21__params.strArg = strArg; 
 22
 23__atlsoap_hr = SetClientStruct(&amp;__params, 0);   
 24if (FAILED(__atlsoap_hr))   
 25{   
 26SetClientError(SOAPCLIENT_OUTOFMEMORY);   
 27goto __skip_cleanup;   
 28}   
 29  
 30__atlsoap_hr = GenerateResponse(GetWriteStream());   
 31if (FAILED(__atlsoap_hr))   
 32{   
 33SetClientError(SOAPCLIENT_GENERATE_ERROR);   
 34goto __skip_cleanup;   
 35}   
 36  
 37__atlsoap_hr = SendRequest(_T("SOAPAction: \"  http://tempuri.org/HelloWorld\"\r\n  "));   
 38if (FAILED(__atlsoap_hr))   
 39{   
 40goto __skip_cleanup;   
 41}   
 42__atlsoap_hr = GetReadStream(&amp;__atlsoap_spReadStream);   
 43if (FAILED(__atlsoap_hr))   
 44{   
 45SetClientError(SOAPCLIENT_READ_ERROR);   
 46goto __skip_cleanup;   
 47}   
 48  
 49// cleanup any in/out-params and out-headers from previous calls   
 50Cleanup();   
 51__atlsoap_hr = BeginParse(__atlsoap_spReadStream);   
 52if (FAILED(__atlsoap_hr))   
 53{   
 54SetClientError(SOAPCLIENT_PARSE_ERROR);   
 55goto __cleanup;   
 56} 
 57
 58*HelloWorldResult = __params.HelloWorldResult;   
 59goto __skip_cleanup;   
 60  
 61__cleanup:   
 62Cleanup();   
 63__skip_cleanup:   
 64ResetClientState(true);   
 65memset(&amp;__params, 0x00, sizeof(__params));   
 66return __atlsoap_hr;   
 67} 
 68
 69流程为: 
 70
 711 初始化参数列表( SetClientStruct(&amp;__params, 0);)   
 72|   
 73V 
 74
 752.生成发送数据请求(GenerateResponse(GetWriteStream());SendRequest(_T("SOAPAction: \" http://tempuri.org/HelloWorld\"\r\n "));)   
 76|   
 77V   
 783.接收和解析回应数据(BeginParse(__atlsoap_spReadStream);)   
 79|   
 80V   
 814.清理工作

161流程与上差不多如果实现分析.asmx?WDSL文件就完全可以vs中的添加web引用的功能，这里   
162剩下的主要是特殊符号的处理和类型转化工作。</istream></tclient></typename>
