用Visual C调用weblogic webservice.pdf (75.6 K)

前段时间研究了以下用Visual C++调用weblogic的webservice，发现与调用微软的webservice还是不同的，用其自带的例子无法实现与weblogic的webservice的通讯，下面和大家分享一下实现的方法。

1．首先，需要安装微软的mssoap tookit 3.0工具包，可以从微软的官方网站上下载；

2．使用weblogic的workshop建立一个web服务。

代码如下所示：

public class add implements com.bea.jws.WebService

{

static final long serialVersionUID = 1L;

/**

* @common:operation

public int AddNumbers(int NumberOne,int NumberTwo)

{

return NumberOne+NumberTwo;

}

仅仅完成一个加法运算即可。

3．查看wsdl文件，内容如下：

<?xml version="1.0" encoding="utf-8"?>

<types>

<s:schema elementFormDefault="qualified" targetNamespace="http://www.openuri.org/" xmlns:s="http://www.w3.org/2001/XMLSchema">

<s:element name="AddNumbers">

<s:complexType>

<s:sequence>

<s:element name="NumberOne" type="s:int"/>

<s:element name="NumberTwo" type="s:int"/>

</s:sequence>

</s:complexType>

</s:element>

<s:element name="AddNumbersResponse">

<s:complexType>

<s:sequence>

<s:element name="AddNumbersResult" type="s:int"/>

</s:sequence>

</s:complexType>

</s:element>

<s:element name="int" type="s:int"/>

</s:schema>

</types>

</message>

</message>

</message>

</message>

</message>

</message>

</operation>

</portType>

</operation>

</portType>

</operation>

</portType>

<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>

<soap:operation soapAction="http://www.openuri.org/AddNumbers" style="document"/>

<input>

<soap:body use="literal"/>

</input>

<soap:body use="literal"/>

</output>

</operation>

</binding>

<http:binding verb="GET"/>

<http:operation location="/AddNumbers"/>

<input>

<http:urlEncoded/>

</input>

<mime:mimeXml part="Body"/>

</output>

</operation>

</binding>

<http:binding verb="POST"/>

<http:operation location="/AddNumbers"/>

<input>

<mime:content type="application/x-www-form-urlencoded"/>

</input>

<mime:mimeXml part="Body"/>

</output>

</operation>

</binding>

<soap:address location="http://localhost:7001/add/add.jws"/>

</port>

<http:address location="http://localhost:7001/add/add.jws"/>

</port>

<http:address location="http://localhost:7001/add/add.jws"/>

</port>

</service>

</definitions>

查看的目的是得到：targetNamespace=http://www.openuri.org/

可以填写在客户端的代码中。

4．运行weblogic workshop的webservice测试工具，通过查看源代码，得到其webservice的地址。注意，这一步和微软的例子是不同的。

得到按钮提交的地址是：http://localhost:7001/add/add.jws/AddNumbers

5．用vc建立一个console的程序，其全部代码如下：

#include <stdio.h>

#import "msxml4.dll"

using namespace MSXML2;

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

exclude("IStream", "IErrorInfo", "ISequentialStream", "_LARGE_INTEGER", \

"_ULARGE_INTEGER", "tagSTATSTG", "_FILETIME")

using namespace MSSOAPLib30;

void Add()

{

ISoapSerializerPtr Serializer;

ISoapReaderPtr Reader;

ISoapConnectorPtr Connector;

// Connect to the service.

Connector.CreateInstance(__uuidof(HttpConnector30));

Connector->Property["EndPointURL"] = "http://localhost:7001/add/add.jws/AddNumbers";

Connector->Connect();

// Begin the message.

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("","STANDARD","");

Serializer->StartBody("");

Serializer->StartElement("AddNumbers","http://www.openuri.org/","","");

//Serializer->StartElement("AddNumbers xmlns=\"http://www.openuri.org/\" ","","","");

//Serializer->StartElement("AddNumbers","","STANDARD","");

Serializer->StartElement("NumberOne","http://www.openuri.org/","","");

Serializer->WriteString("5");

Serializer->EndElement();

Serializer->StartElement("NumberTwo","http://www.openuri.org/","","");

Serializer->WriteString("10");

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", (const char*)Reader->RpcResult->text);

return;

}

int main()

{

CoInitialize(NULL);

Add();

CoUninitialize();

return 0;

}
