Я пытаюсь использовать Django с вызовами AJAX, и это дает мне HTTP 500 даже MultiValueDictKeyError, хотя нет ничего плохого?Ошибка HTTP 500 с Django Ajax
Я послал 3 переменные: SendEmail, имя пользователя, ошибка
Я был в состоянии использовать request.POST на 3 переменных, и получить следующий вывод:
SendEmail = True
имя пользователя = someUserName
ошибка = Войти
Тем не менее, веб-страница возвращается с HTTP 500
View.py:
def loginUser(request):
username = ""
type = ""
logger = logging.getLogger('views.logger.login')
try:
username = request.POST['username'];
logger.info("User:" + username + " in Login Page")
except MultiValueDictKeyError:
logger.info("Cannot Identify User")
try:
type = request.POST['submit']
logger.info("User:" + username + " requests:" + type)
except MultiValueDictKeyError:
logger.info("Cannot Identify User's Request")
if(type=="Login"):
try:
username = request.POST['username']
password = request.POST['password']
logger.info("UserName:" + username + " is trying to login")
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request, user)
logger.info("User is active, and logged in")
return redirect('index.html')
else:
logger.info("User is not active, and will not be logged in")
return redirect('disabled.html')
else:
logger.info("User:" + username + " is not valid");
context = {'Status': "Please sign in", 'Error': "Invalid", 'username':username}
return render(request, 'webapp/login.html', context)
except MultiValueDictKeyError:
logger.info("The user have missing forms")
context = {'Status': "Please sign in", 'Error': "Null"}
return render(request, 'webapp/login.html', context)
except Exception as e:
context = {'Status': "Please sign in", 'Error': "Null"}
return render(request, 'webapp/register.html', context)
logger.error("Error occured in Registering user");
logger.error("Error:" + str(e.args))
elif(type == "Register"):
logger.info("Redirecting user to Register Page")
return redirect('/webapp/register.html')
else:
logger.info("Startup Login Page");
context = {'Status': "Please sign in", 'Error': "Null"}
return render(request, 'webapp/login.html', context)
def ajax_sendMail(request):
logger = logging.getLogger('views.logger.sendEmail')
sendEmail = request.POST['email']
username = request.POST['username']
error = request.POST['error']
logger.info("Sending email to admins, sendEmail:" + sendEmail + ", username:" + username + ", error:" + error)
if(sendEmail == "true"):
mail_admins("User:" + username + " failed to " + error, "The time of error is at:" + datetime.datetime.now())
return HttpResponse("Success in Sending Email")

Я смог успешно отправить вызовы AJAX POST, а в моих view.py функции Ajax_sendEmail я смог получить свои данные. Это детали регистратора:
2014-09-04 16:04:20,901 [INFO] views.logger.login: User:adfafasdfa requests:Login
2014-09-04 16:04:20,901 [INFO] views.logger.login: UserName:adfafasdfa is trying to login
2014-09-04 16:04:21,124 [INFO] views.logger.login: User:adfafasdfa is not valid
2014-09-04 16:04:22,095 [INFO] views.logger.sendEmail: Sending email to admins, sendEmail:true, username:adfafasdfa, error:login
я смог SendEmail, имя пользователя и ошибки, однако он до сих пор называет HTTP 500 MultiValueDictKeyError.
MultiValueDictKeyError at /webapp/sendMail/
"'email'"
Request Method: GET
Request URL: http://127.0.0.1:8000/webapp/sendMail/
Django Version: 1.6.5
Exception Type: MultiValueDictKeyError
Exception Value:
"'email'"
Exception Location: C:\Python27\lib\site-packages\django\utils\datastructures.py in __getitem__, line 301
Python Executable: C:\Python27\python.exe
Python Version: 2.7.6
Кто-нибудь знает, почему это произойдет? Очень странно ...
Что более странно, является хром инспектировать элемент инструмента,
Скриншот Chrome Осмотреть Element инструмент:
Он говорит, что это POST, однако , когда вы идете внутрь:
Это показывает GET
Очень длинный выстрел: есть ли у вас какие-нибудь причудливые посредники? – frnhr
Нет, все стандартные средние – user1157751
