c#下的webservcie 實現代碼,很簡單一看就清楚了是完成什么樣的功能了
using system;
using system.collections;
using system.componentmodel;
using system.data;
using system.diagnostics;
using system.web;
using system.web.services;
namespace webhelloz5
{
/// <summary>
/// service1 的摘要說明。
/// </summary>
public class service1 : system.web.services.webservice
{
public service1()
{
//codegen：該調用是 asp.net web 服務設計器所必需的
initializecomponent();
}
#region component designer generated code
//web 服務設計器所必需的
private icontainer components = null;
/// <summary>
/// 設計器支持所需的方法 - 不要使用代碼編輯器修改
/// 此方法的內容。
/// </summary>
private void initializecomponent()
{
}
/// <summary>
/// 清理所有正在使用的資源。
/// </summary>
protected override void dispose( bool disposing )
{
if(disposing && components != null)
{
components.dispose();
}
base.dispose(disposing);
}
#endregion
// web 服務示例
// helloworld() 示例服務返回字符串 hello world
// 若要生成，請取消注釋下列行，然后保存并生成項目
// 若要測試此 web 服務，請按 f5 鍵
//[webmethod]
//public string helloworld1()
//{
// return "hello world";
//}
[webmethod]
public string helloworld(int narg, string strarg)
{
return strarg+ narg.tostring();
}
}
}
下面就是調用webservice時,網絡上大家發送的數據包了
client請求數據:
post /webhelloz5/service1.asmx http/1.1
host: localhost
content-type: text/xml
content-length: length
soapaction: "http://tempuri.org/helloworld"
<?xml version="1.0" encoding="utf-8"?>
<soap:envelope xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:body>
<helloworld xmlns="http://tempuri.org/">
<narg>int</narg>
<strarg>string</strarg>
</helloworld>
</soap:body>
</soap:envelope>
server回應數據:
http/1.1 200 ok
content-type: text/xml; charset=utf-8
content-length: length
<?xml version="1.0" encoding="utf-8"?>
<soap:envelope xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:body>
<helloworldresponse xmlns="http://tempuri.org/">
<helloworldresult>string</helloworldresult>
</helloworldresponse>
</soap:body>
</soap:envelope>
vc7下的自動生成的代理類,如下所示:
template <typename tclient>
inline hresult cservice1t<tclient>::helloworld(
int narg,
bstr strarg,
bstr* helloworldresult
)
{
hresult __atlsoap_hr = initializesoap(null);
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_initialize_error);
return __atlsoap_hr;
}
cleanupclient();
ccomptr<istream> __atlsoap_spreadstream;
__cservice1_helloworld_struct __params;
memset(&__params, 0x00, sizeof(__params));
__params.narg = narg;
__params.strarg = strarg;
__atlsoap_hr = setclientstruct(&__params, 0);
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_outofmemory);
goto __skip_cleanup;
}
__atlsoap_hr = generateresponse(getwritestream());
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_generate_error);
goto __skip_cleanup;
}
__atlsoap_hr = sendrequest(_t("soapaction: /"http://tempuri.org/helloworld/"/r/n"));
if (failed(__atlsoap_hr))
{
goto __skip_cleanup;
}
__atlsoap_hr = getreadstream(&__atlsoap_spreadstream);
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_read_error);
goto __skip_cleanup;
}
// cleanup any in/out-params and out-headers from previous calls
cleanup();
__atlsoap_hr = beginparse(__atlsoap_spreadstream);
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_parse_error);
goto __cleanup;
}
*helloworldresult = __params.helloworldresult;
goto __skip_cleanup;
__cleanup:
cleanup();
__skip_cleanup:
resetclientstate(true);
memset(&__params, 0x00, sizeof(__params));
return __atlsoap_hr;
}
流程為:
1 初始化參數列表( setclientstruct(&__params, 0);)
|
v
2.生成發送數據請求(generateresponse(getwritestream());sendrequest(_t("soapaction: /"http://tempuri.org/helloworld/"/r/n"));)
|
v
3.接收和解析回應數據(beginparse(__atlsoap_spreadstream);)
|
v
4.清理工作

if __name__ == '__main__':
assert test()
流程與上差不多如果實現分析.asmx?wdsl文件就完全可以vs中的添加web引用的功能，這里
剩下的主要是特殊符號的處理和類型轉化工作。
