python本地html服务器_如何使用Python设置本地HTTP服务器

I am trying to do some basic D3 programming. All the books I am reading talk about setting up a local http server and that is where I am finding myself stuck. I typed the following

python -m http.server

to host the local server. Now, my problem is how to open my html file in this local server? I don't even know how to find the file in the command prompt. Any help will be appreciated. The following is my html file code on aptana. I also have put the d3.js file in the aptana.

D3 Page Template

//D3 codes will go here

When I am running aptana, the html file is opening in a regular firefox page. I want it to open in the locally hosted http server page. Any hints.

The answer is provided when you start the server. In the same directory where you have your HTML file, start the server:

$ python -m http.server

Serving HTTP on 0.0.0.0 port 8000 ...

(Or, the Python2 incantation)

$ python -m SimpleHTTPServer

Serving HTTP on 0.0.0.0 port 8000 ...

In this message, Python tells you the IP address (0.0.0.0) and the port number (8000).

So, if the file is named d3_template.html, you can get to this page via http://0.0.0.0:8000/d3_template.html

On most machines you should also be able to use

http://localhost:8000/d3_template.html

or

http://127.0.0.1:8000/d3_template.html

If you get an error like this:

socket.error: [Errno 48] Address already in use

You want to use a different port:

$ python -m http.server 8888

And to load the file:

http://0.0.0.0:8888/d3_template.html

To understand why all of these work, you'd want to learn a fair bit about networking (ports, DNS, loopback interface, how multiple network cards behave on the same machine and, if things aren't working as expected, firewalls, restricted ports and who knows what else).
