Problem with QHttp

[mridulgandhi]

Hi,

I want to send an XML Schema File to a MULTI-PART server running web-service and the server automatically replies back with an XML File.

I have constructed the Http Header as follows.

QFile infile;
	infile.setFileName("Path\\GetInfoSchema.xsd");
	if (!infile.open(QIODevice::ReadOnly)) 
	{
        return;
    }
	QByteArray inputStr(infile.readAll());
 
	outfile.setFileName("Path\\webSrvResult.xml");
    outfile.open(QIODevice::WriteOnly | QIODevice::Truncate);
 
	QUrl url("webserver/PelletTestWebServiceWeb/");
	http->setHost(url.host(), url.port(80));
 
QHttpRequestHeader header("POST", "http://xyzserver:8080/PelletTestWebServiceWeb/XmlQueryInterface");
header.setValue("multipart/mixed", "application/x-www-form-urlencoded");
http->request(header,inputStr, &outfile);

QFile infile;
	infile.setFileName("Path\\GetInfoSchema.xsd");
	if (!infile.open(QIODevice::ReadOnly)) 
	{
        return;
    }
	QByteArray inputStr(infile.readAll());

	outfile.setFileName("Path\\webSrvResult.xml");
    outfile.open(QIODevice::WriteOnly | QIODevice::Truncate);

	QUrl url("webserver/PelletTestWebServiceWeb/");
	http->setHost(url.host(), url.port(80));

QHttpRequestHeader header("POST", "http://xyzserver:8080/PelletTestWebServiceWeb/XmlQueryInterface");
header.setValue("multipart/mixed", "application/x-www-form-urlencoded");
http->request(header,inputStr, &outfile);

But the problem is that I am unable to get back the XML document from the server using this. I am being told that this is due to the fact that the server is Multipart.

But I am unable to solve this.

Can anyone please help?

Thanks!

What do you mean that you are unable to get the xml document back? Don't you receive any response from the server?

Yeah I am unable to get the XML from the server because it is a Multi-part server. I don't know how to send multi-part requests in Qt.
Please Help

So it's not that you can't get something back but rather that you don't know how to send a properly formatted data to the server, right? I suggest you take a network sniffer and intercept a browser connection to the server handling the request and look how the data should be formatted. Alternatively craft an artificial server (like using netcat or a simple hand-written tcp server), get a form that uses multipart formatting, redirect it to your artificial server and use a browser to send such request. Then you'll know how the data should look like. Yet another way is to use a web search engine to find out how multi-part requests are formed.
