源文件 | mod_autoindex.c |
The index of a directory can come from one of two sources:
index.html
. The DirectoryIndex
directive sets the
name of this file. This is controlled by
mod_dir
.AddIcon
, AddIconByEncoding
和AddIconByType
are
used to set a list of icons to display for various file types;
for each file listed, the first icon listed that matches the
file is displayed. These are controlled by
mod_autoindex
.The two functions are separated so that you can completely remove (or replace) automatic index generation should you want to.
Automatic index generation is enabled with using
Options +Indexes
. See the
Options
directive for
more details.
If the FancyIndexing
option is given with the IndexOptions
directive,
the column headers are links that control the order of the
display. If you select a header link, the listing will be
regenerated, sorted by the values in that column. Selecting the
same header repeatedly toggles between ascending and descending
order. These column header links are suppressed with
IndexOptions
directive's
SuppressColumnSorting
option.
Note that when the display is sorted by "Size", it's the actual size of the files that's used, not the displayed value - so a 1010-byte file will always be displayed before a 1011-byte file (if in ascending order) even though they both are shown as "1K".
Apache 2.0.23 reorganized the Query Arguments for Column
Sorting, and introduced an entire group of new query options.
To effectively eliminate all client control over the output,
the IndexOptions
IgnoreClient
option was introduced.
The column sorting headers themselves are self-referencing hyperlinks that add the sort query options shown below. Any option below may be added to any request for the directory resource.
C=N
sorts the directory by file nameC=M
sorts the directory by last-modified
date, then file nameC=S
sorts the directory by size, then file
nameC=D
sorts the directory by description, then
file nameO=A
sorts the listing in Ascending
OrderO=D
sorts the listing in Descending
OrderF=0
formats the listing as a simple list
(not FancyIndexed)F=1
formats the listing as a FancyIndexed
listF=2
formats the listing as an
HTMLTable FancyIndexed listV=0
disables version sortingV=1
enables version sortingP=pattern
lists only files matching
the given pattern
Note that the 'P'attern query argument is tested
after the usual IndexIgnore
directives are processed,
and all file names are still subjected to the same criteria as
any other autoindex listing. The Query Arguments parser in
mod_autoindex
will stop abruptly when an unrecognized
option is encountered. The Query Arguments must be well formed,
according to the table above.
The simple example below, which can be clipped and saved in a header.html file, illustrates these query options. Note that the unknown "X" argument, for the submit button, is listed last to assure the arguments are all parsed before mod_autoindex encounters the X=Go input.
<form action="" method="get">
Show me a <select name="F">

AddAlt
provides the alternate text to
display for a file, instead of an icon, for FancyIndexing
.
File is a file extension, partial filename, wild-card
expression or full filename for files to describe.
If String contains any whitespace, you have to enclose it
in quotes ("
或'
). This alternate text
is displayed if the client is image-incapable, has image loading
disabled, or fails to retrieve the icon.

File is a file extension, partial filename, wild-card
expression or full filename for files to describe.
String is enclosed in double quotes ("

AddDescription "The planet Mars" /web/pics/mars.gif
The typical, default description field is 23 bytes wide. 6
more bytes are added by the IndexOptions SuppressIcon
option, 7 bytes are
added by the IndexOptions SuppressSize
option, and 19 bytes are
added by the IndexOptions SuppressLastModified
option.
Therefore, the widest default the description column is ever
assigned is 55 bytes.
See the DescriptionWidth IndexOptions
keyword for details on overriding the size
of this column, or allowing descriptions of unlimited length.
Descriptive text defined with AddDescription
may contain HTML markup, such as tags and character entities. If the
width of the description column should happen to truncate a tagged
element (such as cutting off the end of a bolded phrase), the
results may affect the rest of the directory listing.

where alttext
is the text tag given for an icon for non-graphical browsers.
Name is either ^^DIRECTORY^^

模块 | mod_autoindex |
HeaderName
directive sets the name
of the file that will be inserted at the top of the index
listing. Filename is the name of the file to include.
HeaderName HEADER.html
Both HeaderName and ReadmeName
now treat
Filename as a URI path relative to the one used to
access the directory being indexed. If Filename begins
with a slash, it will be taken to be relative to the DocumentRoot
.
HeaderName /include/HEADER.html
Filename must resolve to a document with a major
content type of text/*
(例如,text/html
, text/plain
, etc.). This means
that filename may refer to a CGI script if the script's
actual file type (as opposed to its output) is marked as
text/html
such as with a directive like:
AddType text/html .cgi
Content negotiation
will be performed if Options
MultiViews
is in effect. If filename resolves
to a static text/html
document (not a CGI script) and
either one of the options
Includes
或IncludesNOEXEC
is enabled,
the file will be processed for server-side includes (see the
mod_include
documentation).
If the file specified by HeaderName
contains
the beginnings of an HTML document (<html>, <head>, etc.)
then you will probably want to set IndexOptions
+SuppressHTMLPreamble
, so that these tags are not
repeated.

to emit XHTML 1.0 code instead of HTML 3.2.Apache 1.3.3 introduced some significant changes in the
handling of IndexOptions
directives. In
particular:
IndexOptions
directives for a
single directory are now merged together. The result of:
<Directory /foo>
IndexOptions HTMLTable
IndexOptions SuppressColumnsorting
</Directory>
will be the equivalent of
IndexOptions HTMLTable SuppressColumnsorting
+
或-
).Whenever a '+' or '-' prefixed keyword is encountered, it
is applied to the current IndexOptions
settings (which may have been inherited from an upper-level
directory). However, whenever an unprefixed keyword is processed, it
clears all inherited options and any incremental settings encountered
so far. Consider the following example:
IndexOptions +ScanHTMLTitles -IconsAreLinks FancyIndexing
IndexOptions +SuppressSize
The net effect is equivalent to IndexOptions FancyIndexing
+SuppressSize
, because the unprefixed FancyIndexing
discarded the incremental keywords before it, but allowed them to
start accumulating again afterward.
To unconditionally set the IndexOptions
for
a particular directory, clearing the inherited settings, specify
keywords without any +
或-
prefixes.

模块 | mod_autoindex |
IndexOrderDefault
directive is used
in combination with the FancyIndexing
index option. By default, fancyindexed
directory listings are displayed in ascending order by filename; the
IndexOrderDefault
allows you to change this
initial display order.
IndexOrderDefault
takes two
arguments. The first must be either Ascending
或Descending
, indicating the direction of the sort.
The second argument must be one of the keywords Name
, Date
, Size
, or Description
,
and identifies the primary key. The secondary key is
always the ascending filename.
You can force a directory listing to only be displayed in a
particular order by combining this directive with the SuppressColumnSorting
index option; this will prevent
the client from requesting the directory listing in a different
order.
