1. 登录的完整示例
复习:
form表单往后端提交数据需要注意哪三点: 五一回来默写 <-- 谁写错成from谁就请大家吃雪糕
1. form不是from,所有获取用户输入的标签都应该放在form里面, 并且必须要有name属性
2. action属性控制往哪儿提交,method一般都设置成post
3. 提交按钮必须是type=submit,不能是别的类型
2. GET请求和POST请求
GET请求:
1. 浏览器请求一个页面
2. 搜索引擎检索关键字的时候
POST请求:
1. 浏览器向服务端提交数据,比如登录/注册等
点击登录后：
以上详细程序：
urls.py
1 from .views import yimi, xiaohei, login, baobao 2 #保存路径和函数的对应关系 3 urlpatterns = [ 4 url(r'^yimi/', yimi), #路径，函数 5 url(r'^xiaohei/', xiaohei), 6 url(r'^login/', login), 7 url(r'^baobao/', baobao) 8 ]
views.py
1 from django.shortcuts import HttpResponse, render 2 3 # 函数在views 4 def yimi(request): 5 # request参数保存了所有和用户浏览器请求相关的数据 6 # return HttpResponse('hello yimi!') #不用自己设置状态码，响应头 7 8 #################################################################### 9 # with open("templates/yimi.html", "r", encoding="utf-8") as f: 10 # data = f.read() 11 # return HttpResponse(data) 12 ####################################################################### 13 '''上下方法一样''' 14 return render(request, "yimi.html")#只需写yimi.html,自己会去templates下找 15 16 def xiaohei(request): 17 # request参数保存了所有和用户浏览器请求相关的数据 18 return HttpResponse('hello xiaohei!') 19 20 def login(request): 21 if request.method == "GET": 22 # get请求 ， 想要获取网页，引擎搜索关键字时 23 return render(request, "login.html") 24 else: 25 # 如果是POST请求，向后端提交数据 登录，注册等等 26 email = request.POST.get("email", None) 27 pwd = request.POST.get("pwd", None) 28 print(email, pwd) 29 return HttpResponse("shit hole") #页面显示 30 31 # post请求 32 def baobao(request):# login的表单 action 传到 baobao 33 print(request.POST) #终端打印 34 email = request.POST.get("email", None) 35 pwd = request.POST.get("pwd", None) 36 print(email, pwd) 37 return HttpResponse("shit hole") #页面显示
