Uploading file to a different web platform using ASP.NET/VB.NET

[brianinbox@gmail.com]

Hi,
I've been trying to upload file using webclient.uploa dfile method
from my IIS webserver to an Apache webserver without any success. On
the Apache server (server that receives the incoming file) I have a
simple php script, getFile.php to receive the file. The script look
like this:

<?php
$uploadDir = '/var/www/Incoming/';
$uploadFile = $uploadDir . $_FILES['userfile']['name'];
print "<pre>";
if (move_uploaded_ file($_FILES['userfile']['tmp_name'], $uploadFile))
{
print "File is valid, and was successfully uploaded. ";
print "Here's some more debugging info:\n";
print_r($_FILES );
}
else
{
print "Error receiving file:\n";
print_r($_FILES );
}
print "</pre>";
?>

I know this script work perfectly if I use a standard html with <input
type="file"> method. However, file needs to be sent from an
asp.net page instead of html. People on the newsgroup have been
suggesting me to use webclient.uploa dfile method, however, I just could
not get it to work.

Perhaps there is something wrong with my php script or maybe there
something else needs to be done to the webclient. If anybody has came
across with the similar situation, can you show me how to do it both on
the ASP.NET side and php side (or perl)


Thanks
Brian

This aspect of the question would best be suited in a php
newsgroup/community. If you have related ASP.NET code using the
UploadFile method then you can post that here.

It might be a php and ASP.NET question and that's why I have it posted
here.

In my asp.net form I have

wc as new webclient
wc.uploadfile(" http://sample.com/getFile.php", "POST",
"c:\temp\text.t xt") and I also tried
wc.uploadfile(" http://sample.com/getFile.php", "c:\temp\text.t xt"),
non of them returned any error, however the file never get uploaded.

thanks

i haven't tested (use an network sniff or create a dump page), but suspect
the name is not correct. the standard format is

-----------------------------7d01ecf406a6
Content-Disposition: form-data; name="myfile";
filename="C:\In etpub\wwwroot\U pload\myFile.tx t"
Content-Type: text/plain

this is some test data

-----------------------------7d01ecf406a6

name equals the the name of the input file control in the html version

<input type=file name="myfile>

filename is the name of the file selected.

as the webclient control does not allow to to specify the formdata name, it
is either leaving it out or making one up. but your php script probably
requies it.

This is a bug in WebClient.Uploa dFile() that exists since .NET 1.0. It
does not create a syntactically correct multipart/form-data request.
You'll have to use WebRequest instead and build your own
multipart/form-data request.

Cheers,
