Delphi 调用WebService 直接发送SOPA报文

有一些WebService使用D7的HTTPRIO控件已经不能正常调用了，

这个时候可以直接使用HTTPReqResp控件直接发送报文，

或者使用TIdHTTP控件 http post方式请求 webservicessoap协议接口

函数示例：

HTTPReq: THTTPReqResp;

function TDM_Demo.WebSrvMain( In_fkey_XML,In_funccode,In_fparam_XML:String):String;

var

  DataMsg:WideString;

  strStream, strSend: TStringStream;

begin

//使用SOPAUI等工具获得标准示例报文DataMsg

  DataMsg:='<?xml version="1.0" encoding="utf-8"?>'+

  '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"'+

  ' xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" '+

  'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" '+

  'xmlns:xsd="http://www.w3.org/2001/XMLSchema">'+

'<SOAP-ENV:Body>'+

'<m:funMain xmlns:m="http://services.dtshis/">'+

'<In_fkey_XML><![CDATA['+In_fkey_XML+']]></In_fkey_XML>'+

'<In_funccode>'+In_funccode+'</In_funccode>'+

'<In_fparam_XML><![CDATA['+In_fparam_XML+']]></In_fparam_XML>'+

  '</m:funMain></SOAP-ENV:Body></SOAP-ENV:Envelope>';

  strStream := TStringStream.Create('');

  strSend := TStringStream.Create(AnsiToUtf8(DataMsg));//Utf8转码

  try

    HTTPReq.url := '服务地址';

    HTTPReq.Execute(strSend, strStream);

    result := strStream.DataString;

    result := UTF8Decode(result);

//xml    < >  "  转码

    result := StringReplace(result,'&lt;','<',[rfReplaceAll, rfIgnoreCase]);

    result := StringReplace(result,'&gt;','>',[rfReplaceAll, rfIgnoreCase]);

    result := StringReplace(result,'&quot;','"',[rfReplaceAll, rfIgnoreCase]);

//转为delphi XMLDocument 文档

    result := StringReplace(result,'<?xml version="1.0" encoding="UTF-8"?>',

      '<?xml version="1.0" encoding="gb2312"?>',[rfReplaceAll, rfIgnoreCase]);

  finally

    strStream.Free;

    strSend.Free;

  end;

end;

http  post方式请求 webservices soap协议接口

with IdHttp do

    begin

      ProtocolVersion := pv1_1;

      AllowCookies := True;

      ProxyParams.BasicAuthentication := False;

      ProxyParams.ProxyPort := 0;

      Request.ContentLength := -1;

      Request.Accept := 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';

      Request.BasicAuthentication := False;

      Request.ContentType := 'application/x-www-form-urlencoded';

      HTTPOptions :=[hoKeepOrigProtocol, hoInProcessAuth];

      ReadTimeout:=5000;

    end;

    strSend.WriteString(DataMsg);

    result:=IdHttp.Post(sWSDLAddr,strSend);
