Apache httpd 从 2.0 之后,已经不仅仅局限于一个 http 的服务器,更是一个完善而强大,灵活而健壮,且容易扩展的开发平台。开发人员通过定制 Apache 模块,可以几乎无限制的扩展 Apache httpd,使其更好的与实际应用场景匹配,而又无需考虑底层的网络传输细节。这样既可以提高开发效率,节省开发成本,又能充分利用 Apache 本身的健壮性及可靠性

0x1: Apache httpd 开发平台简介

Apache httpd 自 2.0 之后,针对 1.0 做了大量的改进,包括对自身内核的改造,扩展机制的改进,APR(Apache Portable Runtime) 的剥离(使得 Apache 成为一个真正意义的跨平台服务器)。Apache 2.0 成为一个很容易扩展的开发平台

Apache 中包含了大量的扩展模块(module),如 mod_cgi 用以处理 cgi 脚本、mod_perl 用以处理 perl 脚本,将 perl 的能力与 Apache httpd 结合起来等等。用户可以通过一定的开发标准(接口规范)来开发符合自己业务场景的模块,并动态的加载到 Apache 中,Apache 会根据配置文件中的规则来定位,调用模块,完成客户端请求,简单来说,apache的扩展编写可以分类一下几类

. apache httpd 模块: 编写模块往往要比编写过滤器要复杂一点,可以看成是一种原始的apache扩展编写方式,但是灵活性更高
. 输出过滤器: apache在模块的基础上进行了API封装,使得过滤器的代码编写变得更简单
. 输入过滤器

0x2: Apache httpd 模块机制

Apache httpd 由一个内核和大量的模块组成,包括用以加载其他模块的功能单元自身也是一个模块,模块是Apache扩展的基础机制(理论上模块可以实现任何功能)。一般而言,一个 HTTP 服务器的工作序列是这样的

. 接受客户端请求
可能是请求一个部署在 HTTP 服务器程序可访问的文件,读取该文件作为响应返回,我们在浏览器的地址栏中输入类似这样的 URL:http://host/index.html,浏览器将会尝试与 host 指定的 HTTP 服务器的 80 端口建立连接,如果成功,则发送 HTTP 请求,获取 index.html 页面。如果成功,则在浏览器中解析该 HTML 文件
这种工作方式在静态页面的场景下没有任何问题。但是实际应用往往会与数据库交互,动态生成页面内容。如服务端较为流行的 cgi/php 脚本等。这就需要更高级,更灵活的内容生成器做支持 . 预处理
) 权限校验
) HTTP 头信息识别等 . 内容生成
通过与操作系统其他资源交互 ( 如文件读写,数据库访问等 ) 来完成动态内容的生成 . 其他善后操作等
进行日志记录,资源释放等操作

通常注册模块以处理配置文件中的特殊文件类型或其它此类标准

AddHandler cgi-script .cgi
//php、python都是通过配置指定特定后缀扩展名的处理模块

Apache 为每个请求调用所有处理程序,因此每个处理程序应该迅速决定请求是否是冲着它来的。因此,大多数头文件都从类似下面的语句开始

if (!req->handler || strcmp(req->handler, "target-module"))
return DECLINED;

0x3: Apache 2.0之后的过滤器机制

在大多数时候,apache扩展开发者并不需要很复杂的收包/发包逻辑,而仅仅需要对HTTP Header、Body进行检测,为了提高效率,apache开发者对模块代码进行了API封装
Apache 2.0 有专门的 API 用于开发模块,这些模块只需修改对用户响应的内容,或者只需修改用户的 HTTP 请求的详细信息。这些 API 分别被称为

. 输出过滤器
输出过滤器最为常见,一个好的示例是标准 Apache 2.0 模块,它被用于计算返回给用户的内容的长度以便更新适当的头和日志项。另一个示例是用于对出站内容进行自动拼写检查的模块 . 输入过滤器
典型的WEB WAF

从严格意义上来说,基于WEB SERVER的Mod(扩展模块)WAF是一种HTTP全生命周期的检测/过滤/拦截/记录机制,它需要综合利用"输出过滤器"、"输入过滤器"

1. windows下开发apache模块

0x1: windows下安装apache

http://apache.dataguru.cn//httpd/binaries/win32/
//一定要custom全部安装,否则就不会有include和lib目录

0x2: 安装Perl

将要使用的apx包要用到perl解析编译,所以,需先安装perl

http://www.activestate.com/activeperl  

0x3: 安装apxs

When this happens, these fields are used to chain the subrequests into a linked list.
1. The next field points to the more recent request (or NULL, if there is none),
2. and the prev field points to the immediate ancestor of the request.
3. main points back to the top-level request.

The value of this field may not correspond to the canonical name of your server or the current virtual host but can be any of its DNS aliases.

Ordinarily you will not want to change this directly but will allow Apache to set it based on the return value from your handler.

* handler like this the handler should set r->allowed to the list
* of methods that it is willing to handle. This bitvector is used
* to construct the "Allow:" header required for OPTIONS requests,
* and HTTP_METHOD_NOT_ALLOWED and HTTP_NOT_IMPLEMENTED status codes.
*
* Since the default_handler deals with OPTIONS, all modules can
* usually decline to deal with OPTIONS. TRACE is always allowed,
* modules don't need to set it explicitly.
*
* Since the default_handler will always handle a GET, a
* module which does *not* implement GET should probably return
* HTTP_METHOD_NOT_ALLOWED. Unfortunately this means that a Script GET
* handler can't be installed by mod_actions.

2. mod进阶: 接收客户端数据的 echo 模块

如果Apache模块只能产生内容,那么使用普通的HTML文件(即使用httpd默认的内容生成器)也可以完成。模块存在的意义在于,它可以轻松地处理客户端传递的数据,并将这些数据加工,然后响应客户端请求

**
** $ apxs -c -i mod_helloworld.c

** for the URL /helloworld in as follows:
**

**

3. mod进阶: 可配置的 echo 模块

我们继续扩展上例中的 echo_post 模块,我们将 echo_post 扩展为可配置的模块,通过修改配置文件 httpd.conf 中设置 ConvertType 的值,可以使得模块在运行时的行为发生变化

0x1: 配置信息读取

typedef struct{
int convert_type; // 转换类型
}cust_config_t;

这个结构体仅有一个成员,convert_type, 表示转换类型,如果在配置文件中该值被设置为 0,则将客户端 POST 的数据转换为大写,如果为 1,则转换为小写。这样即可通过配置信息修改模块运行时的行为

//create_config 函数用以创建一个用户自定义的结构体
static void *create_config(apr_pool_t *pool, server_rec *server); //set_mod_config 函数用以设置配置结构体中的成员,这个函数注册在 command_rec 数组中
static const char *set_mod_config(cmd_parms *params, void *config, const char *arg); //而 command_rec 数组则保存在模块声明结构体中: 定义一个 command_rec 结构体类型的数组
static const command_rec cust_echo_cmds[] =
{
AP_INIT_TAKE1("ConvertType",
set_mod_config,
NULL,
RSRC_CONF,
"convert type of post data"),
{}
}; //注册模块回调函数
/* Dispatch list for API hooks */

4. mod进阶: 过滤器

过滤器事实上是另一种形式的模块,Apache对通用的数据结构都做过一些封装,并以库的方式提供(即APR(Apache Portable Runtime))。在过滤器中,有两个比较重要的数据结构

. apr_bucket
. apr_bucket_brigade: apr_bucket_birgade 相当于一个环状队列,而 apr_bucket 是队列中的元素

所有的过滤器形成一个长链,数据从上一个过滤器流入,进行过滤,然后将加工过的数据流入下一个过滤器,处理一个 HTTP 事务期间可能会多次调用某个过滤器,就象不同的块通过“桶队列”。对于所有最普通的过滤器来说,这意味着过滤器必须能够在两次调用之间保存某种上下文
我们的过滤器非常简单,从上一个过滤器中读到数据,将数据中的字符串转换为大写,然后将桶 (apr_bucket) 传递给下一个过滤器。Apache 提供了丰富的 API 来完成这一系列的操作

0x1: 大小写转换过滤器

static apr_status_t case_filter(ap_filter_t *filter, apr_bucket_brigade *bbin)
{
request_rec *req = filter->r;
conn_rec *con = req->connection; apr_bucket *bucket;
apr_bucket_brigade *bbout; //create brigade
bbout = apr_brigade_create(req->pool, con->bucket_alloc); //iterate the full brigade
APR_BRIGADE_FOREACH(bucket, bbin)
{
if(APR_BUCKET_IS_EOS(bucket) || APR_BUCKET_IS_FLUSH(bucket))
{
APR_BUCKET_REMOVE(bucket);
APR_BRIGADE_INSERT_TAIL(bbout, bucket);
return ap_pass_brigade(filter->next, bbout);
}
char *data, *buffer;
apr_size_t data_len; //read content of current bucket in brigade
apr_bucket_read(bucket, &data, &data_len, APR_NONBLOCK_READ);
buffer = apr_bucket_alloc(data_len, con->bucket_alloc);
int i;
for(i = ; i < data_len; i++)
{
//convert
buffer[i] = apr_toupper(data[i]);
} apr_bucket *temp_bucket;
temp_bucket = apr_bucket_heap_create(buffer, data_len, apr_bucket_free, con->bucket_alloc); APR_BRIGADE_INSERT_TAIL(bbout, temp_bucket);
} return APR_SUCCESS;
}

0x2: 注册过滤器

static void filter_echo_post_register_hooks(apr_pool_t *p)
{
ap_register_output_filter(filter_name, case_filter, NULL, AP_FTYPE_RESOURCE);
}

0x3: 运行过滤器模块

对过滤器的配置要稍微复杂一些,在 httpd.conf 中,不但要使用 LoadModule 指令加载过滤器模块,还要使用 SetOutputFilter 指令来指定过滤器的应用场景

LoadModule filter_echo_post_module modules/mod_filter_echo_post.so
AddOutputFilter CaseFilter .cf
//指令中指定,CaseFilter 这个过滤器仅对扩展名为 .cf 的 URL 请求做过滤,其他请求则不过滤
