Thank you, This is a very useful program.

great

THANK YOU!!! Awesome code and really helped ! will always use this when i need to quickly upload stuff to my server! really appreciate it!

gwokae commented Jan 16, 2015

Thanks! And this command can upload file by curl command curl -X POST -F file=@<path-to-file> http://<host-ip>:8000

Hi,

I've forked this gist to port it to Python 3
see: https://gist.github.com/touilleMan/eb02ea40b93e52604938

I've forked this gist and added basic authentication
https://gist.github.com/wonjohnchoi/a4cc44be5dd2f47fd97f

Is there any upload limit ?

Thank you for this. Excellent.

amdei commented Jan 29, 2016

I've forked gist and fix an issue, so absence of 'Content-Type' do not lead to stripping first line of posted data.
https://gist.github.com/amdei/7a83e61373a040697e48

mind adding <meta name='viewport' content='width=device-width,initial-scale=1.0,minimum-scale=1.0'> after each </title> so devices can easily tap the upload form? P.S. thanks for the hand/no-brainer script

mjeff7 commented Feb 19, 2016

Thanks! This helped in a pinch.

I used this scirpt,it works well except one place:
from line 100 to line 104
"line = self.rfile.readline()
remainbytes -= len(line)
line = self.rfile.readline()
remainbytes -= len(line)"

by debugging,I removed first two lines and things go well again.

Hi
I would like to leverage your code.
Can I redistribute your code? What license do you use for the code?

thanks
Louie

非常非常好! 可以,这很python

简直太好了,这很python ~

This script expecting referer from header at line 73
So you have to send referer while upload using curl.

curl -F 'file=@some-data.tar.gz' -H 'referer: http://localhost/' http://localhost:8090/ -v

My fork has that validation https://gist.github.com/arulrajnet/af376482bbe95346824e419b7c9cbdd0

There is a rather strange bug where if the user clicks "upload" without first selecting a file it prints out the permissions error:

try:
            out = open(fn, 'wb')
        except IOError:
            return (False, "Can't create file to write, do you have permission to write?")

Simple fix is to change the error message to include "or did you remember to select a file?"

The bug isn't strange and it's to be expected. An IOError exception is thrown when there is no existing file for python to read, or it can't find it. The same happens when python doesn't have permissions to read it, you can say it just doesn't see it. A simple solution would be a client-side verification with javascript.

Great work!
Here is another simple one-file server python script, with uploading, downloading, ssl, and lots of command line arguments.

..having trouble using it to send an image via javascript, ..my question on stackoverflow

http://stackoverflow.com/questions/41305710/simplehttpserverwithupload-py-post-image-via-javascript

how can i change port?

poplarch commented Apr 1, 2017

@bakaiadam python SimpleHTTPServerWithUpload.py port

How not to list SimpleHTTPServerWithUpload.py file itself ?

fake-name commented May 14, 2017 edited

Please sanitize the upload filename, to prevent parent directory issues. This is as simple as assert os.path.abspath(fn ).startswith(os.path.abspath(self.path)), inserted after line 100.

os.path.abspath() has the effect of collapsing ../ or // in the path, to result in a canonical file-path.

gehaxelt commented May 14, 2017 edited

As @fake-name said, the upload functionality contains a vulnerability, which has been discussed here 0 and here 1.

it will be great if these vulnerabilities are closed.

any suggestion how to delete a file ?
