### HttpSSI模塊 此模塊處理服務器端包含文件(ssi)的處理. 列表中的命令當前并未完全支持. __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 **語法:***ssi [ on | off ]* **默認值:***ssi off* **作用域:***http, server, location* 在location作用域中將啟用SSI文件處理. ### ssi_silent_errors **語法:***ssi_silent_errors [on|off]* **默認值:***ssi_silent_errors off* **作用域:***http, server, location* 在處理SSI文件出錯時不輸出錯誤提示:"[an error occurred while processing the directive] " ### ssi_types **語法:***ssi_types mime-type [mime-type ...]* **默認值:***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 **語法:***ssi_value_length length* **默認值:***ssi_value_length 256* **作用域:***http, server, location* 定義SSI允許使用的參數長度 ### 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 command `include`. Inside the block there can be commands `SSI`. - *name* — the name of the block. For example: : <!--# block name="one" --> : the silencer : <!--# endblock --> : - `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: : <!--# echo var="name" default="no" --> : </code> is the same as <code> : <!--# if expr="$name" --><!--# echo var="name" --><!--# else -->no<!--# endif --> : - `if / elif / else / endif` — conditionally include text or other directives. Usage: .........Only one level of nesting is possible. - *expr* — the expression to evaluate. It can be a variable: ~~~ ~~~ <!--# if expr="$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: ~~~ ~~~ <!--# include virtual="/remote/body.php?argument=value" wait="yes" --> - `set` - assign a variable. - var — the variable. - value — its value. If it contains variable names, these will be evaluated. ### 內置變量 ngx_http_ssi_module 支持兩種內置變量: - `$date_local` - 當前的本地時區時間.配置選項"timefmt"控制格式. - `$date_gmt` - 當前的GMT時間. 配置選項"timefmt"控制格式. ### 參考 [Original Documentation](http://sysoev.ru/nginx/docs/http/ngx_http_ssi_module.html "http://sysoev.ru/nginx/docs/http/ngx_http_ssi_module.html")
