当 def login() 函数调用和 redirect 到 def index() 函数时,我的 url 在浏览器中发生变化,看起来像 http://127.0.0.1:8000/error500index 这个 url。但逻辑上 url 看起来像 http://127.0.0.1:8000/index 这个。但是当我使用重定向功能时,url中显示了error500,error500是我在Project urls.py和APP urls.py中的最后一个url。
有人帮我看看发生了什么事吗?
view.py
from django.shortcuts import render, redirect
from django.contrib import messages
from django.http import HttpResponse
from .models import WebUser
def index(request):
return render(request, 'index.html')
def login(request):
if (request.method == 'POST'):
login_email = request.POST['email']
login_password = request.POST['password']
# Compare with Database where input email exist!
try:
CheckUser = WebUser.objects.get(email=login_email)
except:
return HttpResponse("User Dosen't Exist!")
if (login_email == CheckUser.email and login_password == CheckUser.Password):
#When redirect function call my url change and pick the last url from project urls.py and this url appears in the browser http://127.0.0.1:8000/error500index
return redirect(index)
else:
return HttpResponse("Email or Password are wrong!")
else:
return render(request, 'login.html')
项目 URL.py
from django.contrib import admin
from django.urls import path,include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('SIS_APP.urls')),
path('index', include('SIS_APP.urls')),
path('login', include('SIS_APP.urls')),
path('register', include('SIS_APP.urls')),
path('settings', include('SIS_APP.urls')),
path('weather', include('SIS_APP.urls')),
path('error404', include('SIS_APP.urls')),
path('error500', include('SIS_APP.urls')),
]
APP urls.py
from django.contrib import admin
from django.urls import path
from . import views
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.index, name='index'),
path('index', views.index, name='index'),
path('login', views.login, name='login'),
path('register', views.register, name='register'),
path('settings', views.settings, name='settings'),
path('weather', weatherAPI.weather, name='weather'),
path('error404', views.error404, name='error404'),
path('error500', views.error500, name='error500'),
]
您的网址中缺少斜杠“/”。 URL 是串联的,所以如果你有,即
path('index', views.index, name='index'), ## this will give ..indexsome-sub-route
path('index/', views.index, name='index'), ## this will give ..index/some-sub-route
我认为您没有正确定义 URL。来自 Django 文档。
您将看到重定向可以与硬编码链接一起使用,即:
redirect("/index/")
由于您没有在 URL 中添加斜杠,我们有:
redirect("index")
因此它会将值索引传递给您的 URL。要修复此问题,请将
/
添加到您的 URL 定义中。
