Question

这是我的url.py代码：

urlpatterns = [
    url(r'^test/', views.test, name='test'),
]

这是我的views.py代码：

def test(request):

    print  ("++++++++++++++++++++++++++++++++++++++++++++++++")


    return render(request, 'my_app/index_test.html')

这是我从控制台输出的

Django version 1.10.6, using settings 'some_project.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.

我重新加载页面后或只是去了它，你可以看到它打印++++++++++++++++++++++++++++++++++两次。

我该怎么办？

Answer 1

从日志输出中，我们可以看到第二次调用您的视图函数是由URL /test/images/favicon.ico触发的。你的模板中可能有这样的一行：

<link rel="shortcut icon" href="images/favicon.ico">

请注意，images之前没有斜杠，这意味着该网址将被视为相对于当前网页网址/test/。您应该更改此行以指向您的favicon的正确位置（可能类似于/static/img/favicon.ico），或者如果您没有，则将其完全删除。

网址/test/images/favicon.ico正在触发您的查看功能，因为模式r'^test/'匹配以/test/开头的所有网址。如果您希望仅匹配特定网址/test/，则该行应为：

url(r'^test/$', views.test, name='test'),

Django两次调用view方法
