检索存档文章页的分页链接。
paginate_links( string|array $args = ” )说明（Description）
从技术上讲，该函数可用于为任何区域创建分页链接列表。“base”参数用于引用url，该url将用于创建分页链接。然后使用“format”参数替换页码。但是，在默认情况下，它很可能用于存档日志页。
“type”参数控制返回值的格式。默认值是’plain’，它只是一个由换行符分隔的链接字符串。其他可能的值是“array”或“list”。“array”值将返回分页链接列表的数组，以提供对显示的完全控制。“list”值将把所有分页的链接放在无序的HTML列表中。
“total”参数是总页数，是整数。“current”参数是当前页码，也是整数。
“base”参数的一个例子是”http://example.com/all_posts.php%“%”是必需的。“%”将被“format”参数中的内容替换。“format”参数的一个例子是“？页=%#%”和“%#%”也是必需的。“%#%”将替换为页码。
通过将“prev_next”参数设置为true（默认为true），可以在列表中包含上一个和下一个链接。可以使用“prev_text”参数设置上一个文本。可以通过设置“next_text”参数来设置下一个文本。
如果“show_all”参数设置为true，则它将显示所有页面，而不是当前页面附近的简短页面列表。默认情况下，“show_all”设置为false，并由“end_size”和“mid_size”参数控制。“end U size”参数是开始列表边和结束列表边上的数字数目，默认为1。“mid_size”参数是当前页两边有多少个数字，但不包括当前页。
可以使用“add_args”参数向链接添加查询变量，有关详细信息，请参阅add_query_arg（）。
“before_page_number”和“after_page_number”参数允许用户自己扩展链接。通常，这可能是将上下文添加到编号的链接，以便屏幕阅读器用户了解链接的用途。文本字符串在页码前后添加–在锚定标记内。
返回（Return）
（string|array|void）页面链接的string或页面链接的数组，具体取决于“type”参数。如果总页数小于2，则无效。

/**
* Retrieve paginated link for archive post pages.
*
* Technically, the function can be used to create paginated link list for any
* area. The ‘base’ argument is used to reference the url, which will be used to
* create the paginated links. The ‘format’ argument is then used for replacing
* the page number. It is however, most likely and by default, to be used on the
* archive post pages.
*
* The ‘type’ argument controls format of the returned value. The default is
* ‘plain’, which is just a string with the links separated by a newline
* character. The other possible values are either ‘array’ or ‘list’. The
* ‘array’ value will return an array of the paginated link list to offer full
* control of display. The ‘list’ value will place all of the paginated links in
* an unordered HTML list.
*
* The ‘total’ argument is the total amount of pages and is an integer. The
* ‘current’ argument is the current page number and is also an integer.
*
* An example of the ‘base’ argument is “http://example.com/all_posts.php%_%”
* and the ‘%_%’ is required. The ‘%_%’ will be replaced by the contents of in
* the ‘format’ argument. An example for the ‘format’ argument is “?page=%#%”
* and the ‘%#%’ is also required. The ‘%#%’ will be replaced with the page
* number.
*
* You can include the previous and next links in the list by setting the
* ‘prev_next’ argument to true, which it is by default. You can set the
* previous text, by using the ‘prev_text’ argument. You can set the next text
* by setting the ‘next_text’ argument.
*
* If the ‘show_all’ argument is set to true, then it will show all of the pages
* instead of a short list of the pages near the current page. By default, the
* ‘show_all’ is set to false and controlled by the ‘end_size’ and ‘mid_size’
* arguments. The ‘end_size’ argument is how many numbers on either the start
* and the end list edges, by default is 1. The ‘mid_size’ argument is how many
* numbers to either side of current page, but not including current page.
*
* It is possible to add query vars to the link by using the ‘add_args’ argument
* and see {@link add_query_arg()} for more information.
*
* The ‘before_page_number’ and ‘after_page_number’ arguments allow users to
* augment the links themselves. Typically this might be to add context to the
* numbered links so that screen reader users understand what the links are for.
* The text strings are added before and after the page number – within the
* anchor tag.

* @param string|array $args {
* Optional. Array or string of arguments for generating paginated links for archives.
*
* @type string $base Base of the paginated url. Default empty.
* @type string $format Format for the pagination structure. Default empty.
* @type int $total The total amount of pages. Default is the value WP_Query’s
* `max_num_pages` or 1.
* @type int $current The current page number. Default is ‘paged’ query var or 1.
* @type bool $show_all Whether to show all pages. Default false.
* @type int $end_size How many numbers on either the start and the end list edges.
* Default 1.
* @type int $mid_size How many numbers to either side of the current pages. Default 2.
* @type bool $prev_next Whether to include the previous and next links in the list. Default true.
* @type bool $prev_text The previous page text. Default ‘« Previous’.
* @type bool $next_text The next page text. Default ‘« Previous’.
* @type string $type Controls format of the returned value. Possible values are ‘plain’,
* ‘array’ and ‘list’. Default is ‘plain’.
* @type array $add_args An array of query args to add. Default false.
* @type string $add_fragment A string to append to each link. Default empty.
* @type string $before_page_number A string to appear before the page number. Default empty.
* @type string $after_page_number A string to append after the page number. Default empty.
