Question

File “F:\大四\毕业设计\设计\DSOnline\users\views.py”, line 18, in post
mobile=send_sms_form.cleaned_data[“mobile”]
TypeError: list indices must be integers or slices, not str
Views.py代码如图示

from django.shortcuts import render
from django.views.generic.base import View
from django.contrib.auth import authenticate,login,logout
from django.http import HttpResponseRedirect,JsonResponse
from django.urls import reverse  #通过名称定为Url

from users.forms import LoginForm,DynamicLoginForm
from utils.YunPian import send_single_sms

from DSOnline.settings import yp_apikey

    def post(self,request,*args,**kwargs):
        send_sms_form=DynamicLoginForm(request.POST)
        re_dict={}

                return HttpResponseRedirect(reverse("index"))
            else:
                return render(request, "login.html", {"msg":"用户名或密码错误","login_form":login_form})

        else:
            return render(request, "login.html", {"login_form":login_form})

forms.py代码

from django import  forms
from captcha.fields import CaptchaField

class LoginForm(forms.Form):
    username=forms.CharField(required=True,min_length=2)  #与前端html input名字保持一致
    password=forms.CharField(required=True,min_length=3)


class DynamicLoginForm(forms.Form):
    captcha = CaptchaField()
    mobile = forms.CharField(required=True,min_length=11,max_length=11)

这里报错看来send_sms_form.cleaned_data这个对象是一个list对象 而不是一个dict对象 你可以在这行代码打个断点 然后看看这个对象是什么类型的
