HttpSSI模块
此模块处理服务器端包含文件(ssi)的处理. 列表中的命令当前并未完全支持.
配置示例
location / {
: ssi on;
}
Directives
- [#ssi ssi]
- [#ssi_silent_errors ssi_silent_errors]
- [#ssi_types ssi_types]
- [#ssi_value_length ssi_value_length]
ssi
语法:*ssi [ on | off ]*
默认值:*ssi off*
作用域:*http, server, location* 在location作用域中将启用SSI文件处理.
ssi_silent_errors
语法:*ssi_silent_errors [on|off]*
默认值:*ssi_silent_errors off*
作用域:*http, server, location*
在处理SSI文件出错时不输出错误提示:"[an error occurred while processing the directive] "
ssi_types
语法:*ssi_types mime-type [mime-type ...]*
默认值:*ssi_types text/html*
作用域:*http, server, location*
Enables SSI processing for MIME-types in addition to "text/html" types.
ssi_value_length
语法:*ssi_value_length length*
默认值:*ssi_value_length 256*
作用域:*http, server, location*
定义SSI允许使用的参数长度
SSI 命令
格式示例如下:
: <!--# command parameter1=value parameter2=value... -->
支持的SSI 命令如下:
block
— command describes the block, which can be used as a silencer in commandinclude
. Inside the block there can be commandsSSI
.- name — the name of the block. For example:
: : the silencer : :
config
— assigns some parameters with working SSI.- errmsg — the line, which is derived with the error during the SSI processing. By default, this string is used: "[an error occurred while processing the directive] "
- timefmt — the time formatting string, as used in strftime(3). By default, this string is used:
: "%A, %d-%b-%Y %H:%M:%S %Z" : To include time in seconds use the format "%s" as well.
echo
- print a variable- var — the name of the variable
- default - if the variable is empty, display this string. Defaults to "none". Example:
: : </code> is the same as : no :
if / elif / else / endif
— conditionally include text or other directives. Usage:
.........Only one level of nesting is possible.
- expr — the expression to evaluate. It can be a variable: ~~~
<!--# if expr="$name" --></code> A string comparison: <code><!--# if expr="$name = text" --><!--# if expr="$name != text" --></code> Or a regex match: <code><!--# if expr="$name = /text/" --><!--# if expr="$name != /text/" -->Если в text встречаются переменные, то производится подстановка их значений.
- <code>include — include a document from another source.
- *file* — include a file, e.g.
: <!--# include file="footer.html" --> :
- *virtual* — include a request, e.g.
<!--# include virtual="/remote/body.php?argument=value" -->Multiple requests will be issued in parallel. If you need them issued sequentially, use the "wait" option.
- *stub* — The name of the block to use as a default if the request is empty or returns an error.
<!--# block name="one" --> <!--# endblock --><!--# include virtual="/remote/body.php?argument=value" stub="one" -->
- *wait* — when set to yes, the rest of the SSI will not be evaluated until the current request is finished. Example:
~~~
set
- assign a variable.- var — the variable.
- value — its value. If it contains variable names, these will be evaluated.
内置变量
ngx_http_ssi_module 支持两种内置变量:
$date_local
- 当前的本地时区时间.配置选项"timefmt"控制格式.$date_gmt
- 当前的GMT时间. 配置选项"timefmt"控制格式.
