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

  2. location / {
  3. : ssi  on;
  4. }

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:

  1. : <!--#  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:
    : : 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: ~~~


    1. <!—# 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.
  2. : <!--# include file="footer.html" --> :
  4. - *virtual* — include a request, e.g.
  6. <!--# include virtual="/remote/body.php?argument=value" -->Multiple requests will be issued in parallel. If you need them issued sequentially, use the "wait" option.
  8. - *stub* — The name of the block to use as a default if the request is empty or returns an error.
  10. <!--# block name="one" --> <!--# endblock --><!--# include virtual="/remote/body.php?argument=value" stub="one" -->
  12. - *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.
