New submission from Ent:
Use of http.server.BaseHTTPRequestHandler for exploratory or simple usage,
SimpleHTTPRequestHandler provides a good platform to start on. However, the
current code in SimpleHTTPRequestHandler's send_head is tightly coupled
together as a single unit.
This patch aims to break send_head down into composable parts so that any
developer can subclass SimpleHTTPRequestHandler to create one's own
HTTPRequestHandler class with their own custom behaviour without having to
rewrite a lot of repeated code.
For example consider a developer wanting to address two usecases
* Use SimpleHTTPRequestHandler, but use index.html from a different directory.
* For certain GET urls, call on a specific function to response.
* Use custom html page instead of index.html
class CustomHTTPRequestHandler(SimpleHTTPRequestHandler):
def do_GET(self):
if self.path =='/':
f = self.home_head()
elif self.path in self.custom_paths:
f = self.special_head()
else:
f = self.send_head()
# ...
# Standard Code
As a result of the patch, in above scenario instead of copy-pasting logic for
browser redirection, getting object for file or directory and, applying headers
upon success; Developer can use methods redirect_browser,
get_dir_or_html_dir_path and, apply_headers to reduce the code.
Basically, applying DRY principle.
Note: Since this is but refactoring of existing code without any new
functionality being added, no test cases are provided.
