How can I upload a file (using MooSock)?

[pinacoladaxb]

I'm almost positive that MooSock is what I would use to do this, but I have no idea how. I want the user to be able to upload a screenshot to a directory (more specifically, www.flufferfluff.com/games/battles/images/). I really hate MooSock, so I can already tell this is going to be hard to do. Can anyone help me?

This would be very interesting to know, anyone.

EDIT: Did a quick search, and Google returned this:

How to upload a file using HTTP Protocol

I'm not convinced that's how the websites do it, but there we go, it's what the article says.

Basically so far as i can tell, you're sending it as a form post, but you're setting the value of a 'file' element to the byte data of the file itself. I'm thinking you'd wanna format that so it's URL safe, and of course you'd need a script on the serverside, to convert the variable into a file.

don't use moosock, the protocol is to confusing.

use ftp.

But isn't FTP really unsecure?

You either need an upload script set up on the server ready to receive the file, or you need to use ftp (in which case you obviously need ftp access to the server).

To send a file to an upload script it's something like:
SENDLINE: "POST /folder/upload.php HTTP/1.1"
SENDLINE: "Host: www.example.com"
SENDLINE: "Content-type: multipart/form-data, boundary=AaB03x@:&%CCCds" (the "boundary" string shouldn't exist in the file you're uploading. It can be quite a pain to make one which definitely isn't in the file, so a random one like this one is often used instead.)
SENDLINE: "" (blank line)
SENDLINE: "--AaB03x@:&%CCCds" (this is "--" + the boundary string)
SENDLINE: "content-disposition: form-data; name=""file""; filename=""filename.jpg""" (name is the name of the form field that the script expects, filename is the filename of what you're uploading)
SENDLINE: "Content-Type: image/jpg" (the type of the file you're uploading. Use application/octet-stream if you don't know. See here for more)
SENDLINE: "" (another blank)
SENDFILE (filename.jpg) (send the file with MooSock's send file or send binary command (I don't remember what it's called offhand))
SENDLINE: "--AaB03x@:&%CCCds--" (this is "--" + the boundary string + "--")

Are they gonna steal his images?

and no it just allows for unsecured 'anonymous' transfers but you can add heeps of security.

I should add that this is strictly a vitalized application. That may help...or not.

don't use moosock, the protocol is to confusing.

use ftp.

FTP has not been vitalized. Sorry for not mentioning that earlier.

SENDLINE: "POST /folder/upload.php HTTP/1.1"
SENDLINE: "Host: www.example.com"
SENDLINE: "Content-type: multipart/form-data, boundary=AaB03x@:&%CCCds" (the "boundary" string shouldn't exist in the file you're uploading. It can be quite a pain to make one which definitely isn't in the file, so a random one like this one is often used instead.)
SENDLINE: "" (blank line)
SENDLINE: "--AaB03x@:&%CCCds" (this is "--" + the boundary string)
SENDLINE: "content-disposition: form-data; name=""file""; filename=""filename.jpg""" (name is the name of the form field that the script expects, filename is the filename of what you're uploading)
SENDLINE: "Content-Type: image/jpg" (the type of the file you're uploading. Use application/octet-stream if you don't know. See here for more)
SENDLINE: "" (another blank)
SENDFILE (filename.jpg) (send the file with MooSock's send file or send binary command (I don't remember what it's called offhand))
SENDLINE: "--AaB03x@:&%CCCds--" (this is "--" + the boundary string + "--")

Is that the script for MooSock or FTP?


EDIT: Here's an idea. When someone wants to send the image, they could send it to an application I always have running on my computer (not vitalized) and then that application would upload it. Would that work?

[Dines]

Dynasoft's post is what you're after. It's for MOOSock, just do that, but you'll need a PHP or ASP script to handle the file afterwards.

With PHP (dunno about ASP or CGI), files sent via POST get stored in a temp folder, and will be deleted if they aren't handled properly. The script you link to (folder/uploads.php in Dynasoft's example) should spot the file, validate it, and then move it to the required location.

Although, are you sure you'll be able to load external images from the hard drive in a Vitalize app? It's very security conscious, you may have trouble doing that.

[pinacoladaxb]

Wow, Dynasoft. I originally had you in the credits as "special thanks," but at this rate I'm going to have to promote you to programmer. Thanks for all of your help. I'll try it out and see what happens.

EDIT: Unfortunitely, it didn't work. Here's the events I made in the events editor:


....and here's what's in the upload.php file:

<?php

$target = "images/";
$target = $target . basename( $_FILES['uploaded']['image']) ;

?>

Any idea what I did wrong? :confused:

EDIT 2: I asked MooSock to return what it received, and here it is:

HTTP/1.1 200 OK

This should help.

Ok, looking at the docs for php's $_FILES, I see that:
$_FILES['uploaded']['image']
is wrong, it should be one of:
$_FILES['image']['name'] for the original filename
$_FILES['image']['tmp_name'] for the temporary uploaded filename

Also, seems I missed something, you need to add a "Content-length: xxx" line after the first "content-type: yyy" line, with the size in bytes of all the data you're sending after the first blank line.
The size should be:
(3x"--")+(2xlength of boundary string)+(length of the content-disposition line)+(4xlength of Moosock's end-line symbols, probably 2, could be 1)+(size of the file)
SENDLINE: "Content-length: "+str$(3*len("--")+2*len("AaB03x@:&%CCCds")+len("content-disposition: form-data; name=""file""; filename="""+EditText$("Edit")+"""")+4*2+filesize)

EDIT: Yup, I just sent the following using telnet:

POST /games/battles/upload.php HTTP/1.1
Host: www.flufferfluff.com
Content-type: multipart/form-data, boundary=AaB03x@:&%CCCds
Content-length: 133

--AaB03x@:&%CCCds
content-disposition: form-data; name="image"; filename="testing.txt"

ABC_TESTING_TESTING
--AaB03x@:&%CCCds--

and your server came back with:

HTTP/1.1 200 OK
Date: Thu, 15 May 2008 09:13:48 GMT
Server: Apache/2.2.8 (Unix) mod_ssl/2.2.8 OpenSSL/0.9.8g DAV/2 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635

"200 OK" means success, it worked.
