如果您写login/，它将匹配companies视图。实际上，'login'被str路径转换器接受，因此该视图将被触发。
您可以将login/模式放在首位：
urlpatterns = [
path('', home, name='home'),
path('<b>login/</b>', loginUser, name='login'),
path('logout/', logoutUser, name='logout'),
path('<str:year>/', companies, name='company'),
path('<str:year>/<str:company>', experience, name='experience'),
]
但可能您希望将year变得更具体，并且仅接受数字序列：
urlpatterns = [
path('', home, name='home'),
path('<int:year>/', companies, name='company'),
path('<int:year>/<str:company>', experience, name='experience'),
path('login/', loginUser, name='login'),
path('logout/', logoutUser, name='logout'),
]
英文:
If you write login/ it will match the companies view. Indeed, 'login' is accepted by the str path converter, and thus that view will fire.
You can put the login/ pattern first:
<pre><code>urlpatterns = [
path('', home, name='home'),
path('<b>login/</b>', loginUser, name='login'),
path('logout/', logoutUser, name='logout'),
path('<str:year>/', companies, name='company'),
path('<str:year>/<str:company>', experience, name='experience'),
]</code></pre>
but likely you want to make the year more specific, and only accept a sequence of digits:
<pre><code>urlpatterns = [
path('', home, name='home'),
path('<<b>int:</b>year>/', companies, name='company'),
path('<<b>int:</b>year>/<str:company>', experience, name='experience'),
path('login/', loginUser, name='login'),
path('logout/', logoutUser, name='logout'),
]</code></pre>
