Known Subclasses:

Handler that's just initialized with streams, environment, etc.

This handler subclass is intended for synchronous HTTP/1.0 origin servers, and handles sending the entire response output, given the correct inputs.

Usage:

   handler = SimpleHandler(
       inp,out,err,env, multithread=False, multiprocess=True
   )
   handler.run(app)

Method Details

get_stdin(self)

Override in subclass to return suitable 'wsgi.input'

Overrides: BaseHandler.get_stdin: (inherited documentation)

get_stderr(self)

Override in subclass to return suitable 'wsgi.errors'

Overrides: BaseHandler.get_stderr: (inherited documentation)

add_cgi_vars(self)

Override in subclass to insert CGI variables in 'self.environ'

Overrides: BaseHandler.add_cgi_vars: (inherited documentation)

_write(self, data)

Override in subclass to buffer data for send to client

It's okay if this method actually transmits the data; BaseHandler just separates write and flush operations for greater efficiency when the underlying system actually has such a distinction.

Overrides: BaseHandler._write: (inherited documentation)

_flush(self)

Override in subclass to force sending of recent '_write()' calls

It's okay if this method is a no-op (i.e., if '_write()' actually sends the data.

Overrides: BaseHandler._flush: (inherited documentation)
