3Note: BaseHTTPRequestHandler doesn't implement any HTTP request; see
4SimpleHTTPRequestHandler for simple implementations of GET, HEAD and POST,
5and CGIHTTPRequestHandler for CGI scripts.
6
7It does, however, optionally implement HTTP/1.1 persistent connections,
8as of version 0.3.
9
10Notes on CGIHTTPRequestHandler
11------------------------------
12
13This class implements GET and POST requests to cgi-bin scripts.
14
15If the os.fork() function is not present (e.g. on Windows),
Amaury Forgeot d'Arccb0d2d72008-06-18 22:19:22 +0000[diff] [blame]16subprocess.Popen() is used as a fallback, with slightly altered semantics.
Georg Brandl24420152008-05-26 16:32:26 +0000[diff] [blame]17
18In all cases, the implementation is intentionally naive -- all
19requests are executed synchronously.
20
21SECURITY WARNING: DON'T USE THIS CODE UNLESS YOU ARE INSIDE A FIREWALL
22-- it may execute arbitrary Python code or external programs.
23
24Note that status code 200 is sent prior to execution of a CGI script, so
25scripts cannot send other status codes such as 302 (redirect).
26
27XXX To do:
28
29- log requests even later (to capture byte count)
30- log user-agent header and other interesting goodies
31- send error log to separate file

56# Here's a quote from the NCSA httpd docs about log file format.
57#
58# | The logfile format is as follows. Each line consists of:
59# |
60# | host rfc931 authuser [DD/Mon/YYYY:hh:mm:ss] "request" ddd bbbb
61# |
62# | host: Either the DNS name or the IP number of the remote client
63# | rfc931: Any information returned by identd for this person,
64# | - otherwise.
65# | authuser: If user sent a userid for authentication, the user name,
66# | - otherwise.
67# | DD: Day
68# | Mon: Month (calendar name)
69# | YYYY: Year
70# | hh: hour (24-hour format, the machine's timezone)
71# | mm: minutes
72# | ss: seconds
73# | request: The first line of the HTTP request as sent by the client.
74# | ddd: the status code returned by the server, - if not available.
75# | bbbb: the total number of bytes sent,
76# | *not including the HTTP/1.0 header*, - if not available
77# |
78# | You can determine the name of the file accessed through request.
79#
80# (Actually, the latter is only true if you know the server configuration
81# at the time the request was made!)

142
143 The following explanation of HTTP serves to guide you through the
144 code as well as to expose any misunderstandings I may have about
145 HTTP (so you don't need to read the code to figure out I'm wrong
146 :-).
147
148 HTTP (HyperText Transfer Protocol) is an extensible protocol on
149 top of a reliable stream transport (e.g. TCP/IP). The protocol
150 recognizes three parts to a request:
151
152 1. One line identifying the request type and path
153 2. An optional set of RFC-822-style headers
154 3. An optional data part
155
156 The headers and data are separated by a blank line.
157
158 The first line of the request has the form
159
160 <command> <path> <version>
161
162 where <command> is a (case-sensitive) keyword such as GET or POST,
163 <path> is a string containing path information for the request,
164 and <version> should be the string "HTTP/1.0" or "HTTP/1.1".
165 <path> is encoded using the URL encoding scheme (using %xx to signify
166 the ASCII character with hex code xx).
167
168 The specification specifies that lines are separated by CRLF but
169 for compatibility with the widest range of clients recommends
170 servers also handle LF. Similarly, whitespace in the request line
171 is treated sensibly (allowing multiple spaces between components
172 and allowing trailing whitespace).
173
174 Similarly, for output, lines ought to be separated by CRLF pairs
175 but most clients grok LF characters just fine.
176
177 If the first line of the request has the form
178
179 <command> <path>
180
181 (i.e. <version> is left out) then this is assumed to be an HTTP
182 0.9 request; this form has no optional headers and data part and
183 the reply consists of just the data.
184
185 The reply form of the HTTP 1.x protocol again has three parts:
186
187 1. One line giving the response code
188 2. An optional set of RFC-822-style headers
189 3. The data
190
191 Again, the headers and data are separated by a blank line.
192
193 The response code line has the form
194
195 <version> <responsecode> <responsestring>
196
197 where <version> is the protocol version ("HTTP/1.0" or "HTTP/1.1"),
198 <responsecode> is a 3-digit response code indicating success or
199 failure of the request, and <responsestring> is an optional
200 human-readable string explaining what the response code means.
201
202 This server parses the request and the headers, and then calls a
203 function specific to the request type (<command>). Specifically,
204 a request SPAM will be handled by a method do_SPAM(). If no
205 such method exists the server sends an error response to the
206 client. If it exists, it is called with no arguments:
207
208 do_SPAM()
209
210 Note that the request name is case sensitive (i.e. SPAM and spam
211 are different requests).
212
213 The various request details are stored in instance variables:
214
215 - client_address is the client IP address in the form (host,
216 port);
217
218 - command, path and version are the broken-down request line;
219
Barry Warsaw820c1202008-06-12 04:06:45 +0000[diff] [blame]220 - headers is an instance of email.message.Message (or a derived
Georg Brandl24420152008-05-26 16:32:26 +0000[diff] [blame]221 class) containing the header information;
222
223 - rfile is a file object open for reading positioned at the
224 start of the optional input data part;
225
226 - wfile is a file object open for writing.
227
228 IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING!
229
230 The first thing to be written must be the response line. Then
231 follow 0 or more header lines, then a blank line, and then the
232 actual data (if any). The meaning of the header lines depends on
233 the command executed by the server; in most cases, when data is
234 returned, there should be at least one header line of the form
235
236 Content-type: <type>/<subtype>
237
238 where <type> and <subtype> should be registered MIME types,
239 e.g. "text/html" or "text/plain".
