登录/ MultiValueDictKeyError / "uname，
提问于 2020-03-24 22:26:40
我正在用python mysql和django开发一个电子商务网站。在登录期间，我在/ MultiValueDictKeyError /处获得登录。有人能检查一下这个吗？
这是我的登录页面，“uname”出现错误：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<center>
<form action="/login/" method="POST">
{% csrf_token %}
<input type="text" name="uname" placeholder="username"><br><br>
<input type="text" name="pass" placeholder="password"><br><br>
<input type="submit" value="Login">
</form>
</center>
</body>
</html>这是我使用POST方法的views.py：
from django.shortcuts import render, redirect, HttpResponse
from django.http import HttpResponse
from . models import *
def home(request):
return render(request,'index.html')
def fn_login(request):
v_username = request.POST['uname']
v_password = request.POST['pass']
try:
login_obj = Login.objects.get(username=v_username,password=v_password)
if login_obj.password == v_password:
return render(request,'index.html')
return HttpResponse('incorrect password')
except Exception as e:
print(e)
return HttpResponse('invalid username')这是我的应用程序urls.py：
from django.contrib import admin
from django.urls import path
# importing views from views..py
from .import views
urlpatterns = [
path('index/',views.home),
path('login/',views.fn_login,),
] 我的错误是这样的：

Django Version: 3.0.4

你能试着换一下吗？
v_username = request.POST['uname']
v_password = request.POST['pass']请看下面的
v_username = request.POST.get('uname')
v_password = request.POST.get('pass')页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
