Failed HTTP GET
Community Forums/General Help/Failed HTTP GET
| ||
| Hi everyone, I'm currently trying to wrap my head around some of the HTTP methods to write an online high score table with Blitz and PHP. Here's the general plan: 1. Scores sent to the script using HTTP POST 2. Scores managed by script, update data base, echoed to screen 3. HTTP GET the page with the echoed data 4. Parse and display in program The PHP script is working as planned, but I'm having issues getting the Blitz program to access the script. My problem is I can't seem to perform a GET on my script, currently located at home.fuse.net/csauer_9781/test.php. I used Mark's example in the code archives just to be sure it wasn't a code issue. Also, I can't ping that location or get any IP info. Is this because it doesn't have a domain name associated with it? Any advice? Thanks, |

| I can ping it: dan@Babylon:~$ dan@Babylon:~$ ping home.fuse.net PING php.fuse.net (66.161.131.50) 56(84) bytes of data. 64 bytes from php.fuse.net (66.161.131.50): icmp_seq=1 ttl=52 time=122 ms 64 bytes from php.fuse.net (66.161.131.50): icmp_seq=2 ttl=52 time=122 ms 64 bytes from php.fuse.net (66.161.131.50): icmp_seq=3 ttl=52 time=122 ms 64 bytes from php.fuse.net (66.161.131.50): icmp_seq=4 ttl=52 time=121 ms ^C --- php.fuse.net ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 121.203/122.113/122.476/0.679 ms dan@Babylon:~$ |

| Ok I just tried pinging it, and got it to work, however I didn't receive any of the packets. So I'm guessing the problem was that I was trying to ping the file itself, which has no IP of its own. Makes sense. So how would I access the contents generated by the PHP script if I cannot preform a GET on the file? Thanks, |

| Too bad I don't own and know little about BMax :) Is the executing the script within (for lack of a better word) BMax? And what could I do with B+? |

| Is the executing the script within (for lack of a better word) BMax? It's a C library for URL data transfers (like HTTP and FTP), which is compiled into the BlitzMax application. And what could I do with B+? I imagine you should be able to do it via raw TCP calls too - but of course then you run into some of the problems you have done. I'm surprised the example from the code archives isn't working for you though. That's why I prefer 3rd-party libraries written by people who know what they're doing - so that I don't need to know :-) |
| ||
| written by people who know what they're doing I believe Mark Sibly wrote that example :) I guess if what you were using is a C library then theoretically I could use it with B+ using DLL's, right? |

| I guess if what you were using is a C library then theoretically I could use it with B+ using DLL's, right? I believe so. I wouldn't know where to start with that in BlitzPlus though... but I'm sure there are plenty of people around here who know how to wrap a third party library for it. |

| There was someone on here that made a game in B3D (I think) where you shot birds, and it was really gory (yet fun) and they had an online score table. I guess I should ask them. Now to find out who that was... |
| ||
| I remember now, it was Devil's Child "Bloody Mess 2nd Shot". I re-read the thread and he mentioned something about "passing a video via URL" which would suggest he's using a similar method that I'm trying to do. He doesn't seem to be around much though... but at least I know it's possible. I wonder how he got his data. His comes from http://www.dev-ch.de/server/bm2/viewhigh.php |

I can "wget" it too.dan@Babylon:~$ dan@Babylon:~$ dan@Babylon:~$ wget home.fuse.net/csauer_9781/test.php --2009-10-25 21:52:53-- http://home.fuse.net/csauer_9781/test.php Resolving home.fuse.net... 66.161.131.50 Connecting to home.fuse.net|66.161.131.50|:80... connected.

Also, what about firewalls? Perhaps the program is blocked from downloading it. |

| Firewall turned off, still fails to connect from Blitz. Here's the code I'm using, from marksibly's code archive entry:
www=OpenTCPStream( "http://home.fuse.net/csauer_9781/test.php",80 )
If Not www RuntimeError "Failed to connect"
WriteLine www,"GET / HTTP/1.1"
WriteLine www,"Host: www.yahoo.com"
WriteLine www,"User-Agent: BlitzBrowser"
WriteLine www,"Accept: */*"
WriteLine www,""
While Not Eof(www)
Print "RECV: " + ReadLine(www)
Wend
CloseTCPStream www
It will work when I just try to get the server, home.fuse.net, but how do I access the file itself? |

You're basically making the request incorrectly. You pass the host name to OpenTCPStream (no "http://" or filename), write the host name in the Host: field (you've stuck Yahoo in there for some reason!) and pass the filename (with starting "/") in the GET field. (Passing just "/" asks for the default file, usually "index.html" or similar.) This works for me:
www=OpenTCPStream( "home.fuse.net",80 )
If Not www RuntimeError "Failed to connect"
WriteLine www,"GET /csauer_9781/test.php HTTP/1.1"
WriteLine www,"Host: home.fuse.net"
WriteLine www,"User-Agent: BlitzBrowser"
WriteLine www,"Accept: */*"
WriteLine www,""
While Not Eof(www)
Print "RECV: " + ReadLine(www)

CloseTCPStream www

You might also find this of interest, unless you just want the very basics as above: BlitzGet Deluxe |

| Hey thanks BlitzSupport, I figured I was just misunderstanding something. Makes sense now; connect to the server (home.fuse.net) with a TCP stream, and call a GET to the path of the file. Thanks again, should have it all together now. I'll take a look at BlitzGet Deluxe too. |
