Question

我正在尝试实施SayHello应用页面。这是我的urls.py内容

from django.urls import path
from hello.views import myView
urlpatterns = [
   path('admin/', admin.site.urls),
   path('sayHello/',myView),
]

将此应用添加到URL后，“ http://127.0.0.1:8000/sayHello/”可以正常工作。

但是'http://127.0.0.1:8000/'向我报告了以下404错误页面。

Page not found (404)
Request Method:    GET
Request URL:    http://127.0.0.1:8000/
Using the URLconf defined in editdojo_project.urls, Django tried these URL patterns, in this order:

admin/
sayHello/
The empty path didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

如何解决此错误？

Answer 1

这是因为您没有与首页相匹配的路由（urls.py文件中为空字符串），例如，如果您这样做，您将在'http://127.0.0.1:8000/中看到相同的HelloWorld '

<button type="button" class="btn btn-primary" 
        data-toggle="modal" data-target="#modal-body-id">

Answer 2

bcoz django首先在urls.py中找到相应的url模式，然后从views.py文件中启动视图... path（'admin /'，admin.site.urls）将u移至http://127.0.0.1:8000/admin，path（'sayHello /'，myView）将u移至http://127.0.0.1:8000/sayHello 但是在urls.py中，您没有与http://127.0.0.1:8000/匹配的网址-通常是索引页或首页，添加索引做到这一点->

urlpatterns = [ 
   path('admin/', admin.site.urls),
   path('sayHello/',myView),
   path('',view),
]

Answer 3

尝试

<nav class="pagination col-md-12">
    <ul class="pagination__list">
        <li><a rel="prev" href="#" class="pagination__previous btn-squae disable">&#8249;</a></li>
        <li><span class="pagination__page btn-squae active">1</span></li>
        <li><a href="#" class="pagination__page btn-squae">2</a></li>
        <li><a href="#" class="pagination__page btn-squae">...</a></li>
        <li><a href="#" class="pagination__page btn-squae">14</a></li>
        <li><a rel="next" href="#" class="pagination__next btn-squae">&#8250;</a></li>
    </ul>
</nav>
