Hi to All,
I want to access a web page and its database from my symbian client with RSocket for connection with my server i write a code but it fails on socket connect method, Please tell me what is wrong over there,

///Code For HTTP;

TUriParser url;
RSocket sockfd;
RSocketServ sess;
RHostResolver iHostResolver;
TNameEntry iNameEntry;
TNameRecord iNameRecord;
TInt err;
_LIT(KMyServer, "http://72.156.123.253:7001/weblogic6/filechek1");

User::LeaveIfError(sess.Connect());
url.Parse(KMyServer);
User::LeaveIfError(sockfd.Open(sess,KAfInet,KSockStream, KProtocolInetTcp));
if (url.Extract(EUriScheme).Compare(_L("http")) != 0)
{
// Invalid URL - didn't start with "HTTP://"
User::Leave(KErrArgument) ;
}
err = iHostResolver.Open(sess,KAfInet,KProtocolInetTcp);
User::LeaveIfError(err);
iHostResolver.Close();
iMyresolveServ.Copy(url.Extract(EUriHost));
TRequestStatus iStatus;
iHostResolver.GetByName(KMyServer, iNameEntry, iStatus);
TInetAddr address ;
address = iNameEntry().iAddr;
address.SetPort (80) ;
sockfd.Connect(address, iStatus);// fails here

sockfd.Close();
sess.Close();

Also I m interested to access authenticated pages with user name and passward. please tell me how can i do this it will be a great help.

Thanks in Advance

Re: Help In HTTP via RSocket

I would recommend you to use an ActiveObject (AO) in your case. Or at least a User::WaitForRequest() (but that is not always preferable). Check any of the socket help on SDK, or search in this forum or FN.Wiki/DIBO for the implementations/tutorials.

Re: Help In HTTP via RSocket

I also think you need to use an Acrive Object (AO). During the setup of the connection control has to be taken away from your code, and other active objects need to be sheduled, which cannot happen when you use something like WaitForRequest(), I might be confusing it with establishing a secure connection. So you can change to an AO as last resort.

I see you call iHostResolver.Close(), before calling iHostResolver.GetByName(KMyServer, iNameEntry, iStatus), you cannot call this on when it is closed, think of iHostResolver as a file, it must be open to read.

_LIT(KMyServer, "http://72.156.123.253:7001/weblogic6/filechek1"); gives an ip address "72.156.123.253" you don't need a dns lookup, it specifies a port "7001" which you overide/ don't use with address.SetPort (80) .
Try code below.

TRequestStatus iStatus;
err = iHostResolver.Open(sess,KAfInet,KProtocolInetTcp);
User::LeaveIfError(err);
iMyresolveServ.Copy(url.Extract(EUriHost));
TInetAddr address ;
err = address.Input(iMyresolveServ);
if( err != KErrNone )  // something other than an ip adress, a dns name maybe? (www.example.com)
{
    iHostResolver.GetByName(iMyresolveServ,iNameEntry,iStatus) ; //do a dns lookup, get ip address
    User::WaitForRequest(iStatus);
    User::LeaveIfError(iStatus); // leave if the name coudn't be resolved
    address = TInetAddr(iNameEntry().iAddr);
}
else // we have a valid IP address (ex. 72.156.123.253)
{
    iHostResolver.GetByAddress(address,iNameEntry,iStatus) ; //do a reverse dns lookup, not really necesary
    User::WaitForRequest(iStatus);
}
iHostResolver.Close();

address.SetPort (7001) ;
sockfd.Connect(address, iStatus);
User::WaitForRequest(iStatus);

Re: Help In HTTP via RSocket

Once connected to the server you make a HTTP GET request with the path "weblogic6/filechek1". There is an HTTP API as well as a webbrowser API, which should make things easy, but I have never used them.

Maybe someone else can help you out with that.

Good luck!

Don't know if this will be of use but take a look at Symbian_OS_End-to-End_Sockets_API_Example_v1_3_en
and Symbian_OS_End-to-End_HTTP_API_Example_v1_3_en
