一、GET请求
举例
article.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>article页面</title> </head> <body> <form action="/vote/result/" method="get"> <h1>文章录入！！！</h1> 文章标题:<input type="text" name="title"/> 文章标题:<input type="text" name="content"/> <br> <input type="submit" value="提交"/> </form> </body> </html>
views.py
def article(request): return render(request,"article.html") def result(request): print(request.method) print(request.GET[‘title‘]) print(request.GET[‘content‘]) return HttpResponse("提交成功")
urls.py
url(r"^article",views.article), url(r"^result",views.result),
浏览器输入：http://127.0.0.1:8000/vote/article
输入内容并提交
GET

二、POST表单提交
注册页面 register.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>注册页面</title> </head> <body> <h1>新用户注册！！！</h1> <form action="/vote/register/" method="post"> {% csrf_token %} <p> 用户名：<input type="text" name="username" required="required">*{{ rename }} </p> <p> 密 码：<input type="text" name="password" required="required">* </p> <p> 手机号码：<input type="text" name="phone"> </p> <p> <input type="submit" value="注册"> </p> </form> </body> </html>
登录页面 login.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>登录页面</title> </head> <body> <h1>欢迎登录</h1> <form action="/vote/login/" method="post"> {% csrf_token %} <p> 登录名：<input type="text" name="username" required="required">* </p> <p> 密 码：<input type="text" name="password" required="required">* </p> <p> <input type="submit" value="登录"> </p> {{ info }} {% if info == "用户未注册！请注册" %} <a href="http://127.0.0.1:8000/vote/register">跳转至注册</a> {% endif %} </form> </body> </html>
models.py
新增User表
class User(models.Model): username = models.CharField(‘登录名‘,max_length=20) password = models.CharField(‘登录密码‘,max_length=100) phone = models.CharField(‘手机号‘,max_length=20)
views.py
注册
def register(request): if request.method == "POST": # 获取用户输入 username = request.POST.get("username",None) password = request.POST.get("password") phone = request.POST.get("phone") # 先从数据库查询是否已经注册过了 user = User.objects.filter(username=username) print(user) if user: res = "%s用户名已经被注册，请更换一个" % username return render(request,‘register.html‘,{‘rename‘:res}) else: se_user = User() se_user.username = username # 密文存储密码 se_user.password = make_password(password) se_user.phone = phone # 保存到数据库 se_user.save() return render(request,"login.html") return render(request,"register.html")
登录
def login(request): if request.method == "POST": username = request.POST.get("username",None) password = request.POST.get("password") user = User.objects.filter(username = username).first() if user is None: return render(request,"login.html",{‘info‘:"用户未注册！请注册"}) if user.username == username: result = check_password(password,user.password) print(result) if result: return HttpResponse("登录成功！") else: return render(request,"login.html",{‘info‘:"用户名或者密码错误！"}) else: return render(request,"login.html",{‘info‘:""})
