Django中，运行出现错误 "OSError: [Errno 22] Invalid argument: "F:\\DjangoProgram\\CampusCounselingSyste
m\\user\\templates\\<WSGIRequest: GET '\\user\\login'>"

解决方案：

views.py

from django.shortcuts import render_to_response
from django.http import HttpResponse
# Create your views here.
def index(request):
    print("ok entered!")
    return HttpResponse("You Entered!")
    # return render_to_response(request,"index.html")
def login(request):
    print("You enter the method of login")
    return render_to_response(request,"login.html")

将render_to_response函数改成render函数

from django.shortcuts import render_to_response
from django.shortcuts import render
# Create your views here.
def index(request):
    print("ok entered!")
    # return HttpResponse("You Entered!")
    return render(request,"index.html")
def login(request):
    print("You enter the method of login")
    return render(request,"login.html")

在PyCharm中也能看到，渲染视图HTML的时候会出现图标，问题成功解决。
