urlpatterns = [ url(r\\\’^captcha/\\\’, include(\\\’captcha.urls\\\’)), ] 添加驗(yàn)證嗎在app.form中建立register_form表單，定義好注冊需要的字段（form可自動生成input框）【form實(shí)現(xiàn)了后臺與前端的交互】

class RegisterForm(forms.Form): Email = forms.EmailField(required=True) Password = forms.CharField(required=True,min_length=5) captcha = CaptchaField() 將form加入RegisterView視圖中，并將form數(shù)據(jù)傳入Template中

class RegisterView(View): def get(self,request): register_form = RegisterForm() return render(request,\\\’register.html\\\’,{\\\’register_form\\\’:register_form}) #將register_form數(shù)據(jù)傳遞給Template 通過Template將register_form傳入html中，生成驗(yàn)證碼（form數(shù)據(jù)可通過Template自動生成input框）

<div class=”form-group marb8 captcha1 “> <label>驗(yàn) 證 碼</label> {{ register_form.captcha }} </div> 完成注冊的后臺邏輯，get方法用于刷新，post方法用于接受用戶信息并進(jìn)行存儲

class RegisterView(View): def get(self,request): register_form = RegisterForm() return render(request,\\\’register.html\\\’,{\\\’register_form\\\’:register_form}) #將register_form數(shù)據(jù)傳遞給Template def post(self, request): register_form = RegisterForm(request.POST) #將post上來的數(shù)據(jù)傳遞給RegisterForm if register_form.is_valid(): #上傳的數(shù)據(jù)符合form表要求，有效 user_name = request.POST.get(\\\’username\\\’,\\\’\\\’) if UserProfile.objects.filter(email=user_name): return render(request, \\\’register.html\\\’, {\\\’register_form\\\’:register_form，\\\’msg\\\’: \\\’用戶已存在\\\’}) # 該邏輯用戶判斷用戶是否已注冊存在 pass_word = request.POST.get(\\\’password\\\’,\\\’\\\’) user_profile = UserProfile() user_profile.username = user_name user_profile.email = user_name #明文數(shù)據(jù)需要經(jīng)過加密后傳入數(shù)據(jù)庫,利用make_password方法加密 user_profile.password = make_password(pass_word) user_profile.save() else: return render(request, \\\’register.html\\\’, {\\\’register_form\\\’: register_form}) # 將register_form數(shù)據(jù)傳遞給Template 注意html中相同的、多余的input會影響文本輸出將value傳回Template中

<input type=”text” id=”id_email” name=”email” value=”{{ register_form.email.value }}” placeholder=”請輸入您的郵箱地址” /> <input type=”password” id=”id_password” name=”password” value=”{{ register_form.password.value }}” placeholder=”請輸入6-20位非中文字符密碼” /> 通過郵箱發(fā)送驗(yàn)證鏈接進(jìn)行注冊激活 Django 使用 QQ / 新浪郵箱發(fā)送郵件配置創(chuàng)建utils文件夾，用于存放工具函數(shù)/類
