Re: [twsocket] HttpSvr send picture stream
Thank you for the code. I have solved the problem. It was caused by other
modules which are not thread safe. The bug ate up HttpSvr's memory space.
Best regards,
Kyin

Hello,
I have developed something similiar to your needs on my application, I have
an HttpSrv that should send an internal stored JPEG to the clients over an
GET request to this JPEG, and it is working just fine, please check this
code, this should be implemented on CommandGET event (ICS 6) (Actually, my
source is written in Delphi, but should be easy to port to C++):
//Create the stream to send the data
StreamImg := TMemoryStream.Create;
try
//Read the data from my internal JPEG buffer
Cam.Comunicacao.HTTPImg.ReadImage(StreamImg);
//Fill the file data and send
AResponseInfo.ContentType :=
FHTTP.MIMETable.GetFileMIMEType('.jpg');
AResponseInfo.ContentLength := StreamImg.Size;
AResponseInfo.WriteHeader;
AContext.Connection.IOHandler.Write(StreamImg);
finally
StreamImg.Free;
end;

Subject: [twsocket] HttpSvr send picture stream
Hello!
I am trying to send a JPEG stream stored in memory to HttpCli. Below is my
code. It worked well for first few days and then the server (I mean the
HttpSvr , not the application) just stopped responding to any http request
until I restart the application.
The cause seems to be related to server load. Because I can expediate the
process by open a few clients requesting pictures at half second
interval -
which can kill the http server over one night. I have been trying very
hard
to find out what's wrong here with no luck. The source file is similar to
theHttp Svr demo project - except I replaced the Time portion with JPEG
stream.
Here is what I put in OnGetDocument:
String URL = ((THttpConnection *)Client)-Path;
if(URL.SubString(1, 6)==/frame)
{
Flags = hgWillSendMySelf;
frame[0]-Position = 0; //frames[0] is where the jpeg file stream
stored. If saved to disk, you can get a jpeg file.
String Header = HTTP/1.1 200 OK\r\n
Content-Type: image/jpeg\r\n
Content-Length: + IntToStr(frame[0]-Size)+
\r\n\r\n;
TMemoryStream *Stream = new TMemoryStream;
Stream-Write(Header.data(), Header.Length());
Stream-CopyFrom(frame[0], 0);
Stream-Seek(0, 0);
Flags = hgWillSendMySelf;
((TMyHttpConnection *)Client)-DocStream = Stream;
((TMyHttpConnection *)Client)-SendStream();
}
Thanks - kyin

[twsocket] THttpServer POST data
Anybody knows where I can find a web server demo that can process posted data? For example, I want to get all data posted from a web form and save to database. The current one came with ICS components only shows how to process a GET request. Any help is appreciated.

Thanks Francois. You are right. I didn't use the latest version. I managed to solve the problem by downloading the latest beta version. Thank you.

Be sure to use the latest ICS (V5 or V5) available from my website. Another idea: maybe the camera software use cookies.

[twsocket] HttpCli user authentication whent get()
I tried to set the Username and Password field in my HttpCli component when accessing password protected IP camera without any success. I always get 401 error. But in IE I can enter the same user name and password in the pop=up window to access. I am wondering whether I did anything wrong. My code is: HttpCli1-Username=; HttpCli1-Password=; HttpCli1-URL+192.168.1.98/image.hpg; HttpCli1-Get(); Any help is appreciated!
