转帖--VC6.0调用ASP.NET WebService实例

「爱情、让人受尽委屈。」 2022-08-18 00:57 157阅读 0赞

**开发平台：**

WinXP SP3+IIS5.1+IE7+Visual Studio 2005+Visual Studio 6.0+ MS SOAP Toolkit 3.0

**一．创建ASP.NET WebService**

Visual Studio 2005à文件à新建à网站àASP.NET Web服务项目WebServiceDemo。

以下为Service.cs代码清单：

usingSystem;

usingSystem.Web;

usingSystem.ComponentModel;

usingSystem.Web.Services;

usingSystem.Web.Services.Protocols;

\[WebService(Namespace = "http://Fantasy/WebServiceDemo/")\]

\[System.Web.Services.Protocols.SoapRpcService\]

publicclass Service : System.Web.Services.WebService

public Service()

//如果使用设计的组件，请取消注释以下行

//InitializeComponent();

\[WebMethod\]

public int AddNumbers(int NumberOne,int NumberTwo)

return NumberOne \+ NumberTwo;

生成à生成网站à发布网站。

**二．为WebServiceDemo创建虚拟目录WebServiceDemo**

开始à设置à控制面板à管理工具àInternet信息服务à默认网站à右击新建à虚拟目录WebServiceDemo指向Projects/WebServiceDemo/PrecompiledWeb/WebServiceDemo.

**三．在Web浏览器中输入**[**http://localhost/WebServiceDemo/Service.asmx**][http_localhost_WebServiceDemo_Service.asmx]

出现以下错误：

无法显示 XML 页。

使用 XSL 样式表无法查看 XML 输入。请更正错误然后单击刷新按钮，或以后重试。

--------------------

名称以无效字符开头。处理资源 'http://localhost/WebServiceDemo/Service.asmx' 时出错。第 1 行，位置: 2

<%@ WebService Class="Service" %>

运行C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet\_regiis.exe –i

在cmd窗口中将显示：

开始安装ASP.NET <2.0.50727>。

若要使（局域网）外网访问WebServiceDemo/Service.asmx，则需要为Windows防火墙添加80端口的例外TCP80。在局域网内其他机器的Web浏览器中输入：[http://192.168.89.125/WebServiceDemo/Service.asmx则可访问本机的Service.asmx][http_192.168.89.125_WebServiceDemo_Service.asmx_Service.asmx]。

若出现“此 Web 服务不符合 WS-I Basic Profile v1.1。”错误，则在Web.Config文件中<system.web></system.web>之间添加以下代码：

<removename='BasicProfile1\_1'/>

</conformanceWarnings>

</webServices>

**四．创建****VC6.0****客户端****SOAP****应用程序远程调用****AddNumbers****函数**

参考SOAP Toolkit 3.0 User Guideà Basic Sample Applicationsà Using the Low-Level APIs for SOAP Messages (DocSample2)à Creating a C++ Version of DocSample2à Creating the Client-Side C++ Code

以下为Win32 Console项目SoapDemo的soapDemo.cpp代码清单：

// soapDemo.cpp

\#include<stdio.h>

\#include<stdlib.h>

//先导入msxml4.dll，再导入mssoap30.dll

\#import"msxml4.dll"

usingnamespace MSXML2;

\#import"C:/Program Files/Common Files/MSSoap/Binaries/mssoap30.dll"/

exclude("IStream", "IErrorInfo", "ISequentialStream", /"\_LARGE\_INTEGER","\_ULARGE\_INTEGER", "tagSTATSTG", "\_FILETIME")

usingnamespace MSSOAPLib30;

void Add(int No1,int No2)

//char \*\_itoa( int value, char \*string, int radix );

char str1\[10\],str2\[10\];

itoa(No1,str1,10);itoa(No2,str2,10);

ISoapSerializerPtr Serializer;

ISoapReaderPtr Reader;

ISoapConnectorPtr Connector;

// Connect to the service.

Connector.CreateInstance(\_\_uuidof(HttpConnector30));

Connector->Property\["EndPointURL"\] = "http://localhost/WebServiceDemo/Service.asmx";     Connector->Connect();

// Begin the message.

Connector->Property\["SoapAction"\] = "http://Fantasy/WebServiceDemo/AddNumbers";

Connector->BeginMessage();

// Create the SoapSerializer object.

Serializer.CreateInstance(\_\_uuidof(SoapSerializer30));

// Connect the serializer object to the input stream of the connector object.

Serializer->Init(\_variant\_t((IUnknown\*)Connector->InputStream));

// Build the SOAP Message.

Serializer->StartEnvelope("","","");

//这里可以添加SoapHeader验证代码：

/\*

Serializer->StartHeader("");

Serializer->StartHeaderElement("MyHeader","http://Fantasy/WebServiceDemo/",0,"","NONE","");

Serializer->StartElement("UserName","","","");//填充参数2则出错。

Serializer->WriteString(\_bstr\_t(userName));

\*/

Serializer->StartBody("");

Serializer->StartElement("AddNumbers","http://Fantasy/WebServiceDemo/","","");

//(第三个参数可有可无，若加上第二个参数出错！？)

Serializer->StartElement("NumberOne","","","");// NumberOne=

Serializer->WriteString((\_bstr\_t)str1);

Serializer->EndElement();

Serializer->StartElement("NumberTwo","","","");// NumberOne=

Serializer->WriteString((\_bstr\_t)str2);

Serializer->EndElement();

Serializer->EndBody();

Serializer->EndEnvelope();

// Send the message to the XML Web service.

Connector->EndMessage();

// Read the response.

Reader.CreateInstance(\_\_uuidof(SoapReader30));

// Connect the reader to the output stream of the connector object.

Reader->Load(\_variant\_t((IUnknown\*)Connector->OutputStream), "");

// Display the result.

printf("Answer = %s/n", (constchar\*)Reader->RpcResult->text);

int main()

CoInitialize(NULL);

Add(12,24);

CoUninitialize();

return 0;

**五．SoapDemo客户端调用AddNumbers执行结果:**Answer=36
