webservice端的代码,用于接收和保存二进制图片文件
[WebMethod]
public void SaveDocument(byte[] docbinaryarray, string docname)
{
string strdocPath;
strdocPath = "D:\\test\\share\\" + docname;
FileStream objfilestream = new FileStream(strdocPath, FileMode.Create, FileAccess.ReadWrite);
objfilestream.Write(docbinaryarray, 0, docbinaryarray.Length);
objfilestream.Close();
}
客户端用的soap库
//pfilebuff dwfilelength 为读出的二进制图片
BOOL CTrayDlg::WebServiceCall(char *pFileBuff, DWORD dwFileLength, CString& strRet)
{
HRESULT hRet = FALSE;
CoInitialize(NULL);
ISoapSerializerPtr Serializer;
ISoapReaderPtr Reader;
ISoapConnectorPtr Connector;
try
{
HRESULT hr;
BSTR str = strImgName.AllocSysString();
//与服务器连接
hr = Connector.CreateInstance(__uuidof(HttpConnector30));
if( FAILED(hr) )
{
TRACE("\nSoap 功能缺失! -请确认您的机器上安装有soap3.0或3.0以上版本补丁包, 以及msxml4.0或4.0以上的版本\n");
return FALSE;
}
//调用页面
Connector->Property["EndPointURL"] = _T("http://localhost:53455/manwangchina/Service.asmx?wsdl");
//使用浏览器的代理设置

//连接
hr = Connector->Connect();
//响应函数
Connector->Property["SoapAction"] = _T("http://tempuri.org/SaveDocument");
//启动消息句柄
hr = Connector->BeginMessage();
//SoapSerializer对象
hr = Serializer.CreateInstance(__uuidof(SoapSerializer30));
if( FAILED(hr) )
{
TRACE("\nSoap 功能缺失!请确认您的机器上安装有soap3.0或3.0以上版本补丁包, 以及msxml4.0或4.0以上的版本\n");
return FALSE;
}
//SoapSerializer
hr = Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));
//创建SOAP消息
hr = Serializer->StartEnvelope(_T(""),_T(""),_T(""));
hr = Serializer->StartBody(_T(""));
//找到函数名
hr = Serializer->StartElement(_T("SaveDocument"), _T("http://tempuri.org/"), _T("NONE"), _T(""));
//找到第一个参数
hr = Serializer->StartElement(_T("docbinaryarray"), _T("http://tempuri.org/"), _T("NONE"), _T(""));
IDataEncoderFactoryPtr encoderFc;
encoderFc.CreateInstance(__uuidof(DataEncoderFactory30));
DWORD *len1=new DWORD;
IDataEncoderPtr encoder=encoderFc->GetDataEncoder(L"base64");
encoder->raw_SizeToEncode(pFileBuff,dwFileLength,len1);
byte *data = new byte[dwFileLength+1];
//输入参数值
hr = Serializer->WriteBuffer(dwFileLength, (byte*)data);
//结束
hr = Serializer->EndElement();
//找到第二个参数
hr = Serializer->StartElement(_T("docname"), _T("http://tempuri.org/"), _T("NONE"), _T(""));
//输入参数值
hr = Serializer->WriteString(str);
//结束
hr = Serializer->EndElement();
//----------------------------------
hr = Serializer->EndElement();
hr = Serializer->EndBody();
hr = Serializer->EndEnvelope();
//将该消息发送给web服务
hr = Connector->EndMessage();
hr = Connector->InputStream;
SysFreeString(str);
//读取响应
hr = Reader.CreateInstance(__uuidof(SoapReader30));
//将reader联接到connector的输出字符串
Reader->Load(_variant_t((IUnknown*)Connector->OutputStream), _T(""));
//结果
strRet = (const char*)Reader->RpcResult->text;
hRet = TRUE;
// AfxMessageBox(strRet);
}
catch (_com_error e)
{
TRACE("接口调用失败:%s\n", strMethod);
return FALSE;
}
catch (...)
{
return FALSE;
}
return hRet;
}
程序总是提示调用SaveDocument失败, 可能出错的代码是
hr = Serializer->WriteBuffer(dwFileLength, (byte*)data);找几天都没有找到出错的原因
