基于django框架开发登录接口的四个方法
文件路径user/login
一、登录接口;get请求 username password url参数传递
二、登录接口:post请求,username password url-encode表单传递
意思实现的功能是 :
①、实现一:用户名和密码都是admin 显示 home.html 提示欢迎登录
②、实现二:用户面和密码错误或者不写 显示error.html 提示参数错误
前端页码 templates添加home.html页面
<html lang="en"><head> <meta charset="UTF-8"> <title>测试平台</title></head><body> <h3>欢迎登录测试平台 ,{{ username}}</h3> <a href="/userapi/logout/">注销</a>></body></html>
代码实现:
@api_view(["GET","POST"])def login(request): if request.method =="GET": username = request.GET.get("username") pwd = request.GET.get("password") elif request.method == "POST": username = request.POST.get("username") pwd = request.POST.get("password") else: return render(request,template_name="error.html",context={"msg":"请求方法错误"}) if username is not None and pwd is not None: if username ==‘admin‘and pwd == "admin": return render(request,"home.html",context={"username":username}) else: return render(request, "error.html", context={"msg": "用户名和密码错误"}) else: return render(request,"error.html",context={"msg":"用户名和密码必填"})第二个实现:前端有完整的登录页面:前端有个登录页面 后端有个登录接口 user/login有用户名和密码前端的 后端user/api/login后端真正的登录接口路由修改:
urlpatterns = [ path(‘hello/‘, views.hello), path(‘login/‘,views.login),#只有一个后端登录接口 path(‘home/‘,views.home), path(‘api/login/‘,views.api_login),#前后端都有的登录接口 path(‘api/logout/‘,views.api_logout)]后端接口层:
def login(request): return render(request,‘login.html‘)
@api_view(["POST"])#有页面返回了所以去掉getdef api_login(request): username = request.POST.get("username") pwd = request.POST.get("password") is_login =request.POST.get(‘is_login‘) if username is not None and pwd is not None: if username ==‘admin‘and pwd == "admin": res = render(request,"home.html",context={"username":username})
else: return render(request, "error.html", context={"msg": "用户名和密码错误"}) else: return render(request,"error.html",context={"msg":"用户名和密码必填"}前端页码 templates添加login.html页面
<html lang="en"><head> <meta charset="UTF-8"> <title>用户登录</title></head><body> <form action="/user/api/login" method="post">#前端提交数据到form表单的action属性,action存实际的请求地址,以post形式 <label>用户名:</label><input name="username"> <br> <label>用户名:</label><input name="pwd"> <br><br> <button type="submit" name="登录">登录</button> </form>></body></html>验证结果:浏览器请求url地址127.0.0.1:8000/user/login->输入用户名和地址调api_login接口 验证逻辑返回相应的页面
