First Assumption: That an extra slash was being added for some reason

 Array ( 
      [10] => stdClass Object ( 
           [term_id] => 10 
           [name] => Mozilla 
           [slug] => mozilla 
           [term_group] => 0 
           [term_taxonomy_id] => 11 
           [taxonomy] => company 
           [description] => 
           [parent] => 504 
           [count] => 8 
           [object_id] => 37085 
           [filter] => raw 
       ) 
 )

这些新知识帮助我得出了一个新的假设。

Second & Correct Assumption: That there was something missing between the two slashes.

前面：示例。com/category/company/mozilla之后：示例。com/company/（缺少父项）/mozilla为了测试这是否是问题所在，我更改了数据库值[parent] => 504 到[parent] => 0 要删除任何父关联并按预期工作以创建正确的url，请执行以下操作：

http://example.com/company/mozilla

如果没有其他人会搜索相同的。要解决此问题，请检查register\\u taxonomy（）重写语法。不应该有尾部斜杠。请注意下面的代码示例中的“/产品类别”不带结尾斜杠：

register_taxonomy(
    \'product-category\',
    array(\'product\', \'post\'), array(
        \'label\' => __(\'Product Categories\'),
        \'rewrite\' => array(\'slug\' => \'/product-category\'),
        \'hierarchical\' => true,
        \'show_admin_column\' => true,
    )
);
