Apache模块 mod_example

说明 一个很简单的Apache模块API演示模块
状态 实验(X)
模块名 example_module
源文件 mod_example.c

概述

Some files in the modules/experimental 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.

mod_example

configure with --enable-example option.
  • Make the server (run "make").

    • To add another module of your own:

    1. cp modules/experimental/mod_example.c modules/new_module/mod_myexample.c
    2. Modify the file.
    3. Create modules/new_module/config.m4.
      1. Add APACHE_MODPATH_INIT(new_module).
      2. Copy APACHE_MODULE line with "example" from modules/experimental/config.m4.
      3. Replace the first argument "example" with myexample.
      4. Replace the second argument with brief description of your module. It will be used in configure --help.
      5. If your module needs additional C compiler flags, linker flags or libraries, add them to CFLAGS, LDFLAGS and LIBS accordingly. See other config.m4 files in modules directory for examples.
      6. Add APACHE_MODPATH_FINISH.
    4. Create module/new_module/Makefile.in. If your module doesn't need special build instructions, all you need to have in that file is include $(top_srcdir)/build/special.mk.
    5. Run ./buildconf from the top-level directory.
    6. Build the server with --enable-myexample

    mod_example

    .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.

    mod_example

    说明 Demonstration directive to illustrate the Apache module API 语法 Example 作用域 server config, virtual host, directory, .htaccess 状态 实验(X) 模块 mod_example

    Example 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".
