simple HTTP server for linux

zvivered · 02-17-2017, 12:42 PM

Hello,

I have to develop a very simple HTTP server running under embedded Linux.

The server gets HTTP requests, reads information from the target and send it back to the client.

Security/Encryption is not required.

Can you provide a simple code sample ?

Thank you,
Z.V

I saw one http server written in Bash recently. However, writing a web server is kind of the "Hello, World!" of networking. Have you tried searching for http servers in your favorite search engine? Here's an old list:

https://gist.github.com/willurd/5720255

But rather than cargo-culting it, you might want to read the HTTP specification and just implement that.

Why? Is there a gun to your head? Do "they" have your children?

Python has a couple examples.

Simple http server:

Code:

python2 -m SimpleHTTPServer 8000

Code:

python3 -m http.server 8000

Open web browser to http://127.0.0.1:8000/

This is a request to write a custom program for you. No one is going to do that. You should hit up a freelancer site.

Unless you mean to use simple python http server or Netcat or something.

You've been here TEN YEARS now; you should have read the LQ Rules and "Question Guidelines" at this point, and know that this isn't the place to come for handouts. We will be happy to HELP you if you have an actual problem, but don't ask us to write your code or look things up for you....Google can give you links to many samples.

Further, you've received answers and been asked questions over the years, but haven't followed up in many of your threads.

i've seen op's*other thread and understand the suspicions.
however this question here i find valid (assuming they're asking existing software).
but it also has been answered already: click the gist in post #2.

I don't think its really answered though -

That is a bit more than running apache, simplehttp, or anything like that. In my mind, to do it correctly, that is going to require a program. AND its going to require explaining what the user means by 'information', 'target', and 'client'.

If the request was 'serving up a text file' or 'serving up the directory' then I would agree that those small web servers in the gist would be good answers.

ok i guess this is above my paygrade.
i assumed that this:

is the definition of server:
get request from me: hey, i want website.
read information from target - the target being an html document.
send it back to the client - send the content of the html doc back to the client.

i guess i'm wrong then.

I might look to the distro packages for solutions first. Some dependencies may be huge.

Lighttpd might be used but there are some command line ones out there. https://www.linux.com/news/which-lig...rver-right-you

nweb.c might work.

Wonder if netcat (nc) or even ftp would do??

You could use node: https://www.npmjs.com/package/node-http-server
