texte = Okay, for the 5.2 release, it is now again possible to fetch a binary file, via [writefile] wrapped around [TCPSend]. And the TCPSend code is still using the improved method of receiving large 'chunks' of data per socket read. Better yet, in combination with the 'skipheader' option for TCP send, the resulting file should be an exact copy of the source. Example: [tcpconnect host=[host]] [writefile file=test.jpg][tcpsend skipheader=T]GET /[path_to_jpg] HTTP/1.0[unurl]%0D%0A[/unurl][!] [/!]Host: [host][unurl]%0D%0A%0D%0A[/unurl][!] [/!][/tcpsend][/writefile] [/tcpconnect] -----Original Message----- From: Scott Anderson [mailto:Sanderson@smithmicro.com] Sent: Thursday, January 22, 2004 10:47 AM To: WebDNA-Talk@talk.smithmicro.com Subject: Re: TcpConnect get files on ver. 5.x BUG BUG BUG Well...let me backup a step... The TCPSend code was updated to receive larger chunks of data, over the open socket, per 'read', and appended to a new temp buffer. After receiving all the data, the temp stream is copied to the return buffer. The old method read the socket one character at a time and appended it directly to the return buffer (which in the case of a wrapping [writefile], appended the character directly to the output file). So I can see how this worked before. Question for Morten: Given your sample code: [!]---------- GET A FILE FROM A GIVEN DOMAIN AND PATH -----------[/!] [text]host=www.domain.com[/text] [text]path=/path_to_file_location/on_the_webserver[/text] [text]filename=filename.jpg[/text] [TCPConnect host=[host]] [writefile file=incoming/[filename]][TCPSend]GET [path]/[filename][unurl]%0D%0A[/unurl][/TCPSend][/writefile] [/TCPConnect] The resulting file (as Alain also pointed out), would contain the HTTP resonse headers. Would this not corrupt the image file? -----Original Message----- From: Scott Anderson [mailto:Sanderson@smithmicro.com] Sent: Thursday, January 22, 2004 9:45 AM To: WebDNA-Talk@talk.smithmicro.com Subject: Re: TcpConnect get files on ver. 5.x BUG BUG BUG Actually, taking a second look at these posts, I do not think you can use TCPConnect/TPSend to retrieve binary data. The internal buffers only handle ASCII data and will truncate after the first NULL character. Which is probably why you only get the gif header. It has always been like this. I do not see how this could have worked for any WebDNA version. -----Original Message----- From: Gary Krockover [mailto:gary@garykrockover.com] Sent: Thursday, January 22, 2004 9:01 AM To: WebDNA-Talk@talk.smithmicro.com Subject: Re: TcpConnect get files on ver. 5.x BUG BUG BUG I don't have 4.x installed here anywhere to test, but can confirm the same issue in 5.1e developer on Win2k.
