"Introduction"
msgstr
""
#:
library/cgi.rst:47
msgid
""
"A CGI script is invoked by an HTTP server, usually to process user input "
"submitted through an HTML ``<FORM>`` or ``<ISINDEX>`` element."
msgstr
""
#:
library/cgi.rst:50
msgid
""
"Most often, CGI scripts live in the server's special :file:`cgi-bin` "
"directory. The HTTP server places all sorts of information about the request "
"(such as the client's hostname, the requested URL, the query string, and "
"lots of other goodies) in the script's shell environment, executes the "
"script, and sends the script's output back to the client."
msgstr
""
#:
library/cgi.rst:56
msgid
""
"The script's input is connected to the client too, and sometimes the form "
"data is read this way; at other times the form data is passed via the "
"
\"
query string
\"
part of the URL. This module is intended to take care of "
"the different cases and provide a simpler interface to the Python script. "
"It also provides a number of utilities that help in debugging scripts, and "
"the latest addition is support for file uploads from a form (if your browser "
"supports it)."
msgstr
""
#:
library/cgi.rst:63
msgid
""
"The output of a CGI script should consist of two sections, separated by a "
"blank line. The first section contains a number of headers, telling the "
"client what kind of data is following. Python code to generate a minimal "
"header section looks like this::"
msgstr
""
#:
library/cgi.rst:68
msgid
""
"print(
\"
Content-Type: text/html
\"
) # HTML is following\n"
"print() # blank line, end of headers"
msgstr
""
#:
library/cgi.rst:71
msgid
""
"The second section is usually HTML, which allows the client software to "
"display nicely formatted text with header, in-line images, etc. Here's "
"Python code that prints a simple piece of HTML::"
msgstr
""
#:
library/cgi.rst:75
msgid
""
"print(
\"
<TITLE>CGI script output</TITLE>
\"
)\n"
"print(
\"
<H1>This is my first CGI script</H1>
\"

Hello, world!

"Using the cgi module"
msgstr
""
#:
library/cgi.rst:85
msgid
"Begin by writing ``import cgi``."
msgstr
""
#:
library/cgi.rst:87
msgid
"When you write a new script, consider adding these lines::"
msgstr
""
#:
library/cgi.rst:505
msgid
""
"import cgitb\n"
"cgitb.enable()"
msgstr
""
#:
library/cgi.rst:92
msgid
""
"This activates a special exception handler that will display detailed "
"reports in the web browser if any errors occur. If you'd rather not show "
"the guts of your program to users of your script, you can have the reports "
"saved to files instead, with code like this::"
msgstr
""
#:
library/cgi.rst:97
msgid
""
"import cgitb\n"
"cgitb.enable(display=0, logdir=
\"
/path/to/logdir
\"
)"
msgstr
""
#:
library/cgi.rst:100
msgid
""
"It's very helpful to use this feature during script development. The reports "
"produced by :mod:`cgitb` provide information that can save you a lot of time "
"in tracking down bugs. You can always remove the ``cgitb`` line later when "
"you have tested your script and are confident that it works correctly."
msgstr
""
#:
library/cgi.rst:105
msgid
""
"To get at submitted form data, use the :class:`FieldStorage` class. If the "
"form contains non-ASCII characters, use the *encoding* keyword parameter set "
"to the value of the encoding defined for the document. It is usually "
"contained in the META tag in the HEAD section of the HTML document or by "
"the :mailheader:`Content-Type` header. This reads the form contents from "
"the standard input or the environment (depending on the value of various "
"environment variables set according to the CGI standard). Since it may "
"consume standard input, it should be instantiated only once."
msgstr
""
#:
library/cgi.rst:114
msgid
""
"The :class:`FieldStorage` instance can be indexed like a Python dictionary. "
"It allows membership testing with the :keyword:`in` operator, and also "
"supports the standard dictionary method :meth:`~dict.keys` and the built-in "
"function :func:`len`. Form fields containing empty strings are ignored and "
"do not appear in the dictionary; to keep such values, provide a true value "
"for the optional *keep_blank_values* keyword parameter when creating the :"
"class:`FieldStorage` instance."
msgstr
""
#:
library/cgi.rst:122
msgid
""
"For instance, the following code (which assumes that the :mailheader:"
"`Content-Type` header and blank line have already been printed) checks that "
