My Life My Style
自从使用WP以来，为了迎合Search Bot的检索，通常都直接将固定链接从默认的“/?p=postid”改为“/%postname%”，也就是直接显示文章的名称。
个人觉得这样挺好，这样的链接形式比较直观。不过不确定之前的版本有没有类似这样的问题，就是当我的文章名为数字时（见上篇博文《2012》），固定链接即为“domain.com/2012”—-点击访问均跳到404页面~其他的文章没有问题，初步排错结论是纯数字的文章标题解析bug~
由于之前很少有全为数字标题的文章，所以也没发现类似的问题。为此再次翻阅官方说明：
%year%
The year of the post, four digits, for example 2004%monthnum%
Month of the year, for example 05%day%
Day of the month, for example 28%hour%
Hour of the day, for example 15%minute%
Minute of the hour, for example 43%second%
Second of the minute, for example 33%postname%
A sanitized version of the title of the post (post slug field on Edit Post/Page panel). So “This Is A Great Post!” becomes this-is-a-great-post in the URI (see Using only %postname%). Starting Permalinks with %postname% is strongly not recommended for performance reasons.. *** Note – this has been changed and is ok to do since ver. 2.0%post_id%
The unique ID # of the post, for example 423%category%
A sanitized version of the category name (category slug field on New/Edit Category panel). Nested sub-categories appear as nested directories in the URI. Starting Permalinks with %category% is strongly not recommended for performance reasons.%tag%
A sanitized version of the tag name (tag slug field on New/Edit Tag panel). Starting Permalinks with %tag% is strongly not recommended for performance reasons.%author%
A sanitized version of the author name.
可以看到官方其实不推荐单独使用%postname%，大概跟服务器mod-rewrite模块的限制有关，为了稳妥起见，官方还是推荐组合使用。比如：“/%category%/%postname%”
也有很多网友推荐其他的固定链接设定方案，常用的有：
1. /y/m/d/post-name/
写法：/%year%/%monthnum%/%day%/%postname%/2. /y/m/d/post-name.html
写法：/%year%/%monthnum%/%day%/%postname%.html3. /post-id.html
写法：/%post_id%.html4. /post-name/
写法：/%postname%/5. /post-name.html
写法：/%postname%.html6. category/post-name.html
写法：/%category%/%postname%.html7. category/post-id.html
写法：/%category%/%post_id%.html
个人推荐以下两种：
domainname.com/%postname%.html
or
domainname.com/%category%/%postname%.html
加上伪装的.html之后纯数字的文章名称也可以照常访问咯~
以上仅供有需要的朋友参考，如遇问题建议翻阅官方文档，恕本人不负责解答~thx~
