A simple HTTP Server supporting put (python3)

SimpleHTTPPutServer.py

# python3 -m SimpleHTTPPutServer 8080

from http.server import HTTPServer, SimpleHTTPRequestHandler

class PutHTTPRequestHandler(SimpleHTTPRequestHandler):
    def do_PUT(self):
        print(self.headers)
        length = int(self.headers["Content-Length"])
        path = self.translate_path(self.path)
        with open(path, "wb") as dst:
            dst.write(self.rfile.read(length))
        self.send_response(200)
        self.end_headers()


def run(server_class=HTTPServer, handler_class=PutHTTPRequestHandler):
    server_address = ('', 8000)
    httpd = server_class(server_address, handler_class)
    httpd.serve_forever()

if __name__ == '__main__':
    run()

Python 2 is end of life. Why not align to Python 3? If there is something built into Python 3 that could be used instead, would be worth mentioning this here.

Yes this would be great!

Thanks @orgads. That is what I was looking for. It works fine for me.

hello i have a question how can i make simpleHTTPServer work it give error when i use it give it print self.headers
^^^^^^^^^^^^^^^^^^^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?
i use prython 3

Hello @stefanstruik. Check the code that @orgads shared here. If you want to run the first code (of @fabiand ) you need to install python 2.7

I can do you ok in a zip existence for me I still have it for my education

het works thanks jou wel

Crazy how old this snippet is by now.

help i have a question how can i make simpleHTTPServer work it give error when i use it give python: can't open file SimpleHTTPPutServer': [Errno 2] No such file or directory i use Python 3.10.8
gr stefan

I made a few changes to @orgads' implementation --- thank you! --- that suit my needs. The GET method didn't work, because the file content was already binary while _send_response expected the message to be still a string. If you want to read it binary for optimal efficiency, just edit _send_response instead.

Also, I used it in a web-browser, where multiple files where being retrieved. It made me wait for 2 minutes before axios fetched it and I never saw it in the log. This is because the non-threaded version of the previous authors will simply not see the request coming in and ignore it, until axios tries another time (apparently, that is after 2 minutes). I solved it by using a threaded server from the same http.server library.

The disclaimer still holds:

DISCLAIMER: I added protection for access outside the running directory, but I don't guarantee it cannot be bypassed.

I recommend looking at the script --- it's not hard. But for those who don't have the time, the directory being served is expected to be the current working directory of the script (cwd = os.path.normcase(os.getcwd())), so either move to the directory and execute the script from there, or configure it so you can pass a parameter and share your updated version here ;-) I did the former with one of my scripts ("serve": "cd data; python3 ./server.py 8756")

I've updated the gist to stay minimal, but be python3 based.
