django验证码框架（django-simple-captcha）

github详情：

http://django-simple-captcha.readthedocs.io/en/latest/usage.html

安装：

pip install  django-simple-captcha==0.4.6

将captcha添加到setting的app中：

以下添加到urls中：

url(r'^captcha/', include('captcha.urls')),

register.html中，调入下面：

{{ register_from.captcha }}

自动生成验证码图片和input输入框

forms.py

# 验证码from captcha.fields import CaptchaField

# form对注册表单的验证class RegisterForm(forms.Form):    email = forms.EmailField(required=True)    password = forms.CharField(required=True, min_length=5)    # 验证码,参数：错误信息    captcha = CaptchaField(error_messages={'invalid': '验证码错误啊'})

view.py

# 密码 加密from django.contrib.auth.hashers import make_password

class RegisterView(View):    def get(self, request):        register_from = RegisterForm()        return render(request, "register.html", {'register_from': register_from})    def post(self, request):        register_from = RegisterForm(request.POST)        if register_from.is_valid():            user_name = request.POST.get('username', '')            pass_word = request.POST.get('password', '')            user_profile = UserProfile()            user_profile.username = user_name            user_profile.password = pass_word            # 对密码加密            user_profile.password = make_password(pass_word)            user_profile.save()  # 保存到数据库            pass        return render(request, "register.html", {'register_from': register_from})

若报403错误：

</form>前添加：

{% csrf_token %}
