简单例子：
1 #自定义验证类
2 class Check_form1(forms.Form):
3 #user就是要验证的字段,这里对应前端name <input type=‘text‘ name=user>
4 user = fields.CharField()
5 pwd = fields.CharField()
6 email = fields.EmailField()

10 def test_form1(request):
11 if request.method == ‘GET‘:
12 return render(request,‘form1.html‘)
13
14 elif request.method == ‘POST‘:
15 obj = Check_form(request.POST)
16
17 #obj.is_valid()表单验证,全通过返回True,有错误就false
18 result = obj.is_valid()
19 if result:
20
21 #{‘pwd‘: u‘12311‘, ‘user‘: u‘12311‘, ‘email‘: u‘[email protected]‘}
22 print(obj.cleaned_data)
23 else:
24 #打印错误字段
25 #如:<ul class="errorlist"><li>pwd<ul class="errorlist"><li>最小4位</li></ul></li></ul>
26 #返回json格式错误:obj.errors.as_json()
27 # {"pwd": [{"message": "\u6700\u5c0f4\u4f4d", "code": "min_length"}]}
28 print(obj.errors)
29 return HttpResponse("ok")
