Upload File with CURL into Website - batch-file

Question

I try to Upload a File into a Website with cURL on Windows CMD. The html-code looks like this:
<form enctype="multipart/form-data" action="/Filebrowser?Path=/S71500/" method="POST" onsubmit="return checkUploadFile()">
<td><input id="filebrowser_upload_filename" type="file" name="filename" size="30" maxlength="80" style="background-color: transparent;"></td>
<td><input type="submit" value="Datei laden"></td>
</form>
The command i am using is:
curl -F "filename=#/Users/Me/FILE.so" http://localhost:8080
The fail-message is:
Warning: setting file FILE.so failed!
curl: (26) read function returned funny value
What am I doing wrong?

Answer 1

for me, it was a permissions thing. Curl wasn't able to read my file because it wasn't readable. try:
sudo chmod a+r /path/to/your/file
also, make sure to verify that you are logged in as either root or the owner of the file
ls -l /path/to/your/file
will give you info about permissions, ownership, and group for example:
-rw-r--r-- 1 me users 792139 Jul 2 11:23 file.txt
file.txt is readable by root, "me" and members of the group "users" - writable only by root, and not executable by anyone. it contains 792139 bytes

Answer 2

I had the exact same error, while trying to upload with curl:
Warning: setting file testimage.png’ failed!
It comes out to be because my curl command line contained spurious invisible characters from a copy/paste from browser. I copied the command line into a text editor like Sublime Text and then back into terminal: suddenly everything worked.
Probably some UTF8 / ASCII issue.

Answer 3

Instead of -F, we have to use --form-string. Then it will work.

You should place a PHP code in the root directory of your server as below
upload.php
<?php
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['filename']['name']);
if(move_uploaded_file($_FILES['filename']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['filename']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
?>
keep in mind that you must use the argument a capital F (for Form). Lowercase f is for fail
