Apache Module mod_example
| Описание: | Illustrates the Apache module API |
|---|---|
| Статус: | Experimental |
| Идентификатор модуля: | example_module |
| Исходный файл: | mod_example.c |
Summary
The files in the src/modules/example directory
under the Apache distribution directory tree are provided as an
example to those that wish to write modules that use the Apache
API.
The main file is mod_example.c, which
illustrates all the different callback mechanisms and call
syntaxes. By no means does an add-on module need to include
routines for all of the callbacks - quite the contrary!
The example module is an actual working module. If you link it into your server, enable the "example-handler" handler for a location, and then browse to that location, you will see a display of some of the tracing the example module did as the various callbacks were made.
Compiling the example module
To include the example module in your server, follow the steps below:
-
Uncomment the "AddModule modules/example/mod_example" line
near the bottom of the
src/Configurationfile. If there isn't one, add it; it should look like this:AddModule modules/example/mod_example.o - Run the
src/Configurescript ("cd src; ./Configure"). This will build the Makefile for the server itself, and update thesrc/modules/Makefilefor any additional modules you have requested from beneath that subdirectory. - Make the server (run "
make" in thesrcdirectory).
To add another module of your own:
mkdir src/modules/mymodulecp src/modules/example/* src/modules/mymodule- Modify the files in the new directory.
- Follow steps [1] through [3] above, with appropriate changes.
Using the mod_example Module
To activate the example module, include a block similar to
the following in your srm.conf file:
<Location /example-info>
SetHandler example-handler
</Location>
As an alternative, you can put the following into a .htaccess file
and then request the file "test.example" from that location:
AddHandler example-handler .example
After reloading/restarting your server, you should be able to browse to this location and see the brief display mentioned earlier.
Пример Директива
| Описание: | Demonstration directive to illustrate the Apache module API |
|---|---|
| Синтаксис: | Пример |
| Контекст: | server config, virtual host, directory, .htaccess |
| Статус: | Experimental |
| Модуль: | mod_example |
The Пример directive just sets a demonstration
flag which the example module's content handler displays. It
takes no arguments. If you browse to an URL to which the
example content-handler applies, you will get a display of the
routines within the module and how and in what order they were
called to service the document request. The effect of this
directive one can observe under the point "Example
directive declared here: YES/NO".
