How to make Socket Server understand Get ,Post request? Please

[alicenan88]

Hello everyone,

I am a newbie on symbian development.Now, my boss asked me to implement a function like that ,we need to build a socket server,but on the client side, there is a javascript programming to send request in format of HTTP or (restful) , such as Get http://127.0.0.1:8080/data/name of user, then the server need to reply the information of the user to the javascript .

I just don't know is it possible? and if so, how to implement the socket server part, is there anyone can give me some example or useful link? thank u so much!!

Waiting for ur great help.

Faithfully yours

Easier way would be to take the actual HTTP eample and use it, othervise you would need to make the headers etc. by yourself when sending teh request.

where I can find a server example, what I found is all http client,that connected to a server already existed . do u have any suggestion?Thank u so much

Check the menu on top of the page, tools, docs & code --> Code examples might be a good place to start looking from..

yes,I know, I have checked a long long time,but all are about how to set up a client part to connect the existed server part

I´m not a Nokia Expert but as far as I know there isn´t any open source implementation of such basic thing.

You know what?
Here is my single-shot "web server":

void MainL()
{
    _LIT(KHelloWorld,"Hello World");
    _LIT(KFormat,"%d\n");

    CConsoleBase *console=Console::NewL(KHelloWorld,TSize(KConsFullScreen,KConsFullScreen));
    CleanupStack::PushL(console);
    
    RSocketServ sockserv;
    User::LeaveIfError(sockserv.Connect());
    CleanupClosePushL(sockserv);
    
    RConnection connection;
    User::LeaveIfError(connection.Open(sockserv));
    User::LeaveIfError(connection.Start());
    CleanupClosePushL(connection);
    
    RSocket servsock;
    User::LeaveIfError(servsock.Open(sockserv,KAfInet,KSockStream,KProtocolInetTcp,connection));
    CleanupClosePushL(servsock);
    
    TSoInetInterfaceInfo ifinfo;
    TPckg<TSoInetInterfaceInfo> ifinfopkg(ifinfo);
    
    TSoInetIfQuery ifquery;
    TPckg<TSoInetIfQuery> ifquerypkg(ifquery);
    
    TInetAddr addr;
    
    TUint32 iap;
    _LIT(KIapId,"IAP\\Id");
    User::LeaveIfError(connection.GetIntSetting(KIapId, iap));

    User::LeaveIfError(servsock.SetOpt(KSoInetEnumInterfaces, KSolInetIfCtrl));
    while(KErrNone==servsock.GetOpt(KSoInetNextInterface, KSolInetIfCtrl, ifinfopkg))
    {
        ifquery.iName = ifinfo.iName;
        if(KErrNone!=servsock.GetOpt(KSoInetIfQueryByName, KSolInetIfQuery, ifquerypkg))
            break;
        if (ifquery.iZone[1] == iap)
        {
            if(ifinfo.iAddress.Address() > 0)
            {
                addr = ifinfo.iAddress;
                break;
            }
        }
    }

    {
    TBuf <100> buf;
    addr.Output(buf);
    
    _LIT(KNewLine,"\n");
    buf.Insert(0,KNewLine);
    buf.Append(KNewLine);
    console->Printf(buf);
    }
    
    RSocket socket;
    User::LeaveIfError(socket.Open(sockserv));
    CleanupClosePushL(socket);
    
    TRequestStatus status;
    User::LeaveIfError(servsock.SetLocalPort(80));
    User::LeaveIfError(servsock.Listen(4));
    servsock.Accept(socket,status);
    User::WaitForRequest(status);
    User::LeaveIfError(status.Int());
    
    CBufFlat *flat=CBufFlat::NewL(20);
    CleanupStack::PushL(flat);
    TBuf8<100> buf8;
    TSockXfrLength x;
    
    _LIT8(KDoubleNewLine8,"\r\n\r\n");
    
    while(status==KErrNone)
    {
        socket.RecvOneOrMore(buf8,0,status,x);
        User::WaitForRequest(status);
        flat->InsertL(flat->Size(),buf8);
        console->Printf(_L("%d %d\n"),buf8.Length(),flat->Size());
        if(flat->Size()>=4 && flat->Ptr(flat->Size()-4).Compare(KDoubleNewLine8)==0)
            break;
    }
    
    flat->ResizeL(flat->Size()*2);
    TPtr8 ptr8=flat->Ptr(0);
    ptr8.SetLength(ptr8.Length()/2);
    TPtr ptr=ptr8.Expand();
    console->Write(ptr);
   
    _LIT8(KResponse,"HTTP/1.1 200 OK\r\nConnection: close\r\nContent-Type: text/html\r\nContent-Length: 5\r\n\r\nHello");
    socket.Write(KResponse(),status);
    User::WaitForRequest(status);
    
    CleanupStack::PopAndDestroy(5); // flat,socket,servsock,connection,sockserv
    
    CleanupStack::PopAndDestroy(); // console
}

It says 'Hello' to anyone who asks.
