前端Vue3

<template>
  <div>
    <el-form :model="form" label-width="100px">
      <el-form-item label="用户名">
        <el-input v-model="form.username" placeholder="请输入用户名"></el-input>
      </el-form-item>
      <el-form-item label="密码">
        <el-input v-model="form.password" type="password" placeholder="请输入密码"></el-input>
      </el-form-item>
      <el-form-item>
        <el-button type="primary" @click="handleSubmit">登录</el-button>
      </el-form-item>
    </el-form>
  </div>
</template>

<script setup>
import { ref } from 'vue';
import axios from 'axios';

const form = ref({
  username: '',
  password: ''
});

const handleSubmit = () => {
  axios.post('http://127.0.0.1:8000/user/login/', form.value)
    .then(response => {
      if (response.data.status === 'success') {
        alert('登录成功');
        // 登录成功后的逻辑，例如跳转到主页
      } else {
        alert(response.data.message);
      }
    })
    .catch(error => {
      console.error('登录失败', error);
      alert('登录失败，请检查用户名和密码');
    });
};
</script>

后端Django
models.py
用于mysql

# Create your models here.
from django.contrib.auth.models import AbstractUser
from django.db import models

class CustomUser(models.Model):
    # 添加自定义字段
    name = models.CharField(max_length=100, verbose_name="姓名")
    password = models.CharField(max_length=100, verbose_name="密码")

views.py
处理

from django.contrib.auth import authenticate
from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
from django.views.decorators.http import require_http_methods
from .models import CustomUser

@csrf_exempt
@require_http_methods(["POST"])
def user_login(request):
    import json
    data = json.loads(request.body)
    print(data)
    username = data.get('username')
    password = data.get('password')
    password_mysql = CustomUser.objects.get(name=username)
    if password_mysql is not None:
        if password_mysql.password==password:
            return JsonResponse({'status': 'success', 'message': '登录成功'})
        else:
            return JsonResponse({'status': 'error', 'message': '用户名或密码错误'})
    else:
        return JsonResponse({'status': 'error', 'message': '用户名不存在'})

应用的urls.py
路由

from django.urls import path
from . import views

urlpatterns = [
    path('login/', views.user_login, name='login'),
]

项目的urls

from django.contrib import admin
from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('user/', include('myapp.urls')),
