如何使用Django(python)实现android的服务器端_python_

python manage.py startapp Login_sever

DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'androidsevers', 'USER': 'root', 'PASSWORD': '123456', 'PORT': 3306, 'HOST': '', } }

from django.db import models # Create your models here. class Login(models.Model): ID=models.AutoField(primary_key=True) username=models.CharField(max_length=25,verbose_name='用户名') password=models.CharField(max_length=25,verbose_name='密码') adminname=models.CharField(max_length=25,verbose_name='用户姓名')

python manage.py makemigrations

python manage.py migrate

from django.contrib import admin from django.urls import path from Login_sever import views urlpatterns = [ path('admin/', admin.site.urls), path('login/',views.login_view) ]

from django.core.exceptions import ObjectDoesNotExist from django.http import HttpResponse from django.shortcuts import render from Login_sever.models import Login import json def login_view(request): if request.method=='POST': username=request.POST.get('username') password=request.POST.get('password') date_error={ 'username': username, 'adminname': '', 'code':'错误，用户不存在', 'Status Code': 404 } try: user=Login.objects.get(username=username) if user.password==password: data={ 'username':user.username, 'adminname':user.adminname, 'code': '成功', 'Status Code': 200 } return HttpResponse(json.dumps(data), content_type='application/json') else: date_error = { 'username': username, 'adminname': '', 'code': '密码错误', 'Status Code': 404 } return HttpResponse(json.dumps(date_error), content_type='application/json') except ObjectDoesNotExist: return HttpResponse(json.dumps(date_error),content_type='application/json') else: return HttpResponse('GET请求无效') 

ipconfig
