# POST屬性
* QueryDict類型的對象
* 包含post請求方式的所有參數
* 與form表單中的控件對應
* 表單中的那些控件會被提交
* 控件要有name屬性，則name屬性的值為鍵，value屬性的值為鍵，構成鍵值對提交
* 對于CheckBox控，name屬性一樣為一組，當控件被選中后會被提交，存在一鍵多值的情況
* 值是可變的
* 定義視圖login
```text
def login(request):
return render(request,'myapp/login.html')
```
* 配置路由url
```text
url(r'^login/$',views.login),
```
* 創建模板login.html
```text
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form method="post" action="/main/">
姓名: <input type="text" name="name"/><br />
密碼: <input type="password" name="pwd"/><br />
性別: <input type="radio" name="sex" value="1" />男
<input type="radio" name="sex" value="0"/>女<br />
愛好: <input type="checkbox" name="hobby" value="c/c++"/>c/c++
<input type="checkbox" name="hobby" value="python"/>python
<input type="checkbox" name="hobby" value="java"/>java
<input type="checkbox" name="hobby" value="C#"/>C#
<input type="submit" value="value"/>
</form>
</body>
</html>
```
* 創建視圖main接收請求的數據
```text
def main(request):
name = request.POST['name']
password = request.POST['pwd']
sex = request.POST['sex']
hobby = request.POST.getlist('hobby')
context = {'name':name,'password':password,'sex':sex,'hobby':hobby}
return render(request,'myapp/main.html',context)
```
* 配置路由urls.py
```text
url(r'^main/$',views.main),
```
* 創建模板main.html
```text
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{{ name }}
{{ password }}
{{ sex }}
{{ hobby }}
</body>
</html>
```
* 注意:使用表單提交，注釋掉settings.py中的中間件crsf
```text
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
# 'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
```
