怎样使用VC6调用webservice的接口

Posted 2023-04-11

参考技术A 网络上有很多这样的文章，但是无法一次性调试过，下面的程序完全是经过测试了的，可以使用，在这留档下。
代码如下：
/*begin*/
#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; //你机器得安装SOAP Toolkit3.0 ，1.0时，用using namespace时报错
void query(char *EndPointURL,char *NameSpace,char *method,int argv_len,char* argv[])

ISoapSerializerPtr Serializer;
ISoapReaderPtr Reader;
ISoapConnectorPtr Connector;
// Connect to the service
Connector.CreateInstance(__uuidof(HttpConnector30));
Connector->Property["EndPointURL"] = EndPointURL;//接口位置
Connector->Connect();//和服务器连接
// Begin message
Connector->Property["SoapAction"] = _bstr_t(NameSpace)+"/"+_bstr_t(method);//方法名
Connector->BeginMessage();
Serializer.CreateInstance(__uuidof(SoapSerializer30));
// 将serializer连接到connector的输入字符串
Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));
// 创建SOAP消息
Serializer->StartEnvelope("soap","","");
Serializer->StartBody("body");
Serializer->StartElement(method,NameSpace,"","");//命名空间必须有
for(int i=0;i<argv_len;i++)

Serializer->StartElement(argv[i],NameSpace,"","");
Serializer->WriteString(argv[i]);
Serializer->EndElement();


Serializer->EndElement();
Serializer->EndBody();
Serializer->EndEnvelope();
// Send the message to the web service
Connector->EndMessage();
// 读取响应
Reader.CreateInstance(__uuidof(SoapReader30));
// 将reader联接到connector的输出字符串
Reader->Load(_variant_t((IUnknown*)Connector->OutputStream), "");
printf("Answer: %s\n",(const char*)Reader->RpcResult->xml);

int main(int argc, char* argv[])

CoInitialize(NULL);
char *EndPointURL="接口地址";
char *NameSpace="接口地址";
char *method="call"; //接口提供的方法名
int argv_len=4;
char *argu[4]="08SY20310982","100000", "error", "49"; //参数，这里传递了4个，还可以增加
query(EndPointURL,NameSpace,method,argv_len,argu);
CoUninitialize();
getchar();
return 0;

没有wsdl，怎么使用soapui测试webservice接口？

参考技术A soapUI创建，路径里面输入【服务地址】+【接口名？wsdl】 参考技术B soapui调用wsdl，主要用其来查看web service提供的接口，以及返回的结果
