"""HTTP request handler base class.
|
|
|
|
|
|
|
|
|
|
The following explanation of HTTP serves to guide you through the
|
|
|
|
|
code as well as to expose any misunderstandings I may have about
|
|
|
|
|
HTTP (so you don't need to read the code to figure out I'm wrong
|
|
|
|
|
:-).
|
|
|
|
|
|
|
|
|
|
HTTP (HyperText Transfer Protocol) is an extensible protocol on
|
|
|
|
|
top of a reliable stream transport (e.g. TCP/IP). The protocol
|
|
|
|
|
recognizes three parts to a request:
|
|
|
|
|
|
|
|
|
|
1. One line identifying the request type and path
|
|
|
|
|
2. An optional set of RFC-822-style headers
|
|
|
|
|
3. An optional data part
|
|
|
|
|
|
|
|
|
|
The headers and data are separated by a blank line.
|
|
|
|
|
|
|
|
|
|
The first line of the request has the form
|
|
|
|
|
|
|
|
|
|
<command> <path> <version>
|
|
|
|
|
|
|
|
|
|
where <command> is a (case-sensitive) keyword such as GET or POST,
|
|
|
|
|
<path> is a string containing path information for the request,
|
2002-03-17 18:37:22 +00:00
|
|
|
and <version> should be the string "HTTP/1.0" or "HTTP/1.1".
|
|
|
|
|
<path> is encoded using the URL encoding scheme (using %xx to signify
|
|
|
|
|
the ASCII character with hex code xx).
|
1995-08-04 04:00:20 +00:00
|
|
|
|
2003-02-03 15:21:15 +00:00
|
|
|
The specification specifies that lines are separated by CRLF but
|
|
|
|
|
for compatibility with the widest range of clients recommends
|
|
|
|
|
servers also handle LF. Similarly, whitespace in the request line
|
|
|
|
|
is treated sensibly (allowing multiple spaces between components
|
|
|
|
|
and allowing trailing whitespace).
|
1995-08-04 04:00:20 +00:00
|
|
|
|
|
|
|
|
Similarly, for output, lines ought to be separated by CRLF pairs
|
|
|
|
|
but most clients grok LF characters just fine.
|
|
|
|
|
|
|
|
|
|
If the first line of the request has the form
|
|
|
|
|
|
|
|
|
|
<command> <path>
|
|
|
|
|
|
|
|
|
|
(i.e. <version> is left out) then this is assumed to be an HTTP
|
|
|
|
|
0.9 request; this form has no optional headers and data part and
|
|
|
|
|
the reply consists of just the data.
|
|
|
|
|
|
2002-03-17 18:37:22 +00:00
|
|
|
The reply form of the HTTP 1.x protocol again has three parts:
|
1995-08-04 04:00:20 +00:00
|
|
|
|
|
|
|
|
1. One line giving the response code
|
|
|
|
|
2. An optional set of RFC-822-style headers
|
|
|
|
|
3. The data
|
|
|
|
|
|
|
|
|
|
Again, the headers and data are separated by a blank line.
|
|
|
|
|
|
|
|
|
|
The response code line has the form
|
|
|
|
|
|
|
|
|
|
<version> <responsecode> <responsestring>
|
|
|
|
|
|
2002-03-17 18:37:22 +00:00
|
|
|
where <version> is the protocol version ("HTTP/1.0" or "HTTP/1.1"),
|
1995-08-04 04:00:20 +00:00
|
|
|
<responsecode> is a 3-digit response code indicating success or
|
|
|
|
|
failure of the request, and <responsestring> is an optional
|
|
|
|
|
human-readable string explaining what the response code means.
|
|
|
|
|
|
|
|
|
|
This server parses the request and the headers, and then calls a
|
|
|
|
|
function specific to the request type (<command>). Specifically,
|
1999-09-15 15:28:25 +00:00
|
|
|
a request SPAM will be handled by a method do_SPAM(). If no
|
1995-08-04 04:00:20 +00:00
|
|
|
such method exists the server sends an error response to the
|
|
|
|
|
client. If it exists, it is called with no arguments:
|
|
|
|
|
|
|
|
|
|
do_SPAM()
|
|
|
|
|
|
|
|
|
|
Note that the request name is case sensitive (i.e. SPAM and spam
|
|
|
|
|
are different requests).
|
|
|
|
|
|
|
|
|
|
The various request details are stored in instance variables:
|
|
|
|
|
|
|
|
|
|
- client_address is the client IP address in the form (host,
|
|
|
|
|
port);
|
|
|
|
|
|
|
|
|
|
- command, path and version are the broken-down request line;
|
|
|
|
|
|
|
|
|
|
- headers is an instance of mimetools.Message (or a derived
|
|
|
|
|
class) containing the header information;
|
|
|
|
|
|
|
|
|
|
- rfile is a file object open for reading positioned at the
|
|
|
|
|
start of the optional input data part;
|
|
|
|
|
|
|
|
|
|
- wfile is a file object open for writing.
|
|
|
|
|
|
|
|
|
|
IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING!
|
|
|
|
|
|
|
|
|
|
The first thing to be written must be the response line. Then
|
|
|
|
|
follow 0 or more header lines, then a blank line, and then the
|
|
|
|
|
actual data (if any). The meaning of the header lines depends on
|
|
|
|
|
the command executed by the server; in most cases, when data is
|
|
|
|
|
returned, there should be at least one header line of the form
|
|
|
|
|
|
|
|
|
|
Content-type: <type>/<subtype>
|
|
|
|
|
|
|
|
|
|
where <type> and <subtype> should be registered MIME types,
|
|
|
|
|
e.g. "text/html" or "text/plain".
