django 邮箱校验

环境：

方法一: validate_email

def ValidateEmail( email ):
from django.core.validators import validate_email
from django.core.exceptions import ValidationError
try:
validate_email( email )
return True
except ValidationError:
return False

方法二：EmailField

froms.py

class RegisterForm(forms.Form):
'''
注册
'''
username = forms.EmailField(widget=forms.TextInput(attrs={"class": "form-control", "placeholder": "请输入邮箱账号", "value": "", "required": "required",}),
max_length=50,error_messages={"required": "用户名不能为空",})
password = forms.CharField(widget=forms.PasswordInput(attrs={"class": "form-control", "placeholder": "请输入密码", "value": "", "required": "required",}),
min_length=8, max_length=50,error_messages={"required": "密码不能为空",})

def clean(self):

# 用户名
try:
username=self.cleaned_data['username']
except Exception as e:
print 'except: '+ str(e)
raise forms.ValidationError(u"注册账号需为邮箱格式")

return self.cleaned_data

在cleaned_data会校验username的是否为邮箱格式以及是否符合定义时的格式，如果不符合则抛出异常
