1. 注册页面的渲染
使用render_template来渲染，注意这里的前端网页使用jinja2模板
详情大家可以参考jinja2介绍
注意每个网页上方都有导航条，大家可以使用jinja2的继承功能，写一个base.html,其他网页都可以继承这个网页，在其上面扩展
2.邮箱的注册验证
使用falsk-mail库完成
制作一个邮箱服务器，我们这里使用QQ邮箱
在config.py中完成配置即可
再创建一个邮箱的模板，进行数据库交互
验证前端输入的邮箱密码是否输入正确，增加一个forms.py
python">import wtforms
from wtforms.validators import Email, Length, EqualTo, InputRequiredfrom exts import db
from models import UserModel, EmailCaptchaModel# Form :主要验证用来验证前端提交的数据是否符合要求
class RegisterForm(wtforms.Form):email = wtforms.StringField(validators=[Email(message="邮箱格式错误！")])captcha = wtforms.StringField(validators=[Length(max=4, min=4, message="验证码格式错误")])username = wtforms.StringField(validators=[Length(min=3, max=20, message="用户格式错误")])password = wtforms.StringField(validators=[Length(min=6, max=20, message="密码格式错误")])password_confirm = wtforms.StringField(validators=[EqualTo("password", message="两次密码不一致")])# 自定义验证# 1、 邮箱是否被注册def validate_email(self, field):email = field.datauser = UserModel.query.filter_by(email=email).first()if user:raise wtforms.ValidationError(message="该邮箱已经被注册！")# 2、 验证码是否正确def validate_captcha(self, field):captcha = field.dataemail = self.email.datafilters = {'email': email, 'captcha': captcha}captcha_model = EmailCaptchaModel.query.filter_by(**filters).first()# print(email,captcha,captcha_model.email)if not captcha_model:raise wtforms.ValidationError(message="邮箱或者验证码错误")# tode 可以删除 captcha_modelelse:# 使用完毕可以删除 或者 定义是否使用 # False是0,true是1# db.session.delete(captcha_model)# db.session.commit()captcha_model.used = 1db.session.commit()class LoginForm(wtforms.Form):email = wtforms.StringField(validators=[Email(message="邮箱格式错误！")])password = wtforms.StringField(validators=[Length(min=6, max=20, message="密码格式错误")])class QuestionForm(wtforms.Form):title = wtforms.StringField(validators=[Length(max=100, min=4, message="标题格式错误")])content = wtforms.StringField(validators=[Length(min=6, message="内容格式错误")])class AnswerForm(wtforms.Form):content = wtforms.StringField(validators=[Length(min=4, message="内容格式错误")])question_id = wtforms.IntegerField(validators=[InputRequired(message="必须要传入问题id")])
获取从前端输入的邮箱密码
python"># GET :从服务获取数据
# POSt ：将客户端的数据提交个服务器
@bp.route("/register", methods=["POST", "GET"])
def register():if request.method == "GET":if g is None:return redirect("/")log.info("Registering")return render_template("register.html")else:# Post 去请求# 验证用户提交邮箱和验证是否正确# 表单验证：flask-wtfform = RegisterForm(request.form)if form.validate():username = form.username.datapassword = form.password.dataemail = form.email.datauser = UserModel(email=email, username=username, password=generate_password_hash(password))db.session.add(user)db.session.commit()log.info(f"用户： {username} 邮箱地址： {password} 已经注册成功")return redirect(url_for("auth.login"))else:print(form.errors)log.info(f"用户注册验证不通过，即将返回注册页面")return redirect(url_for("auth.register"))3.登录页面的渲染
python">@bp.route("/login", methods=["POST", "GET"])
def login():if request.method == "GET":if g is None:return redirect("/")return render_template("login.html")else:form = LoginForm(request.form)if form.validate():email = form.email.datapassword = form.password.datauser = UserModel.query.filter_by(email=email).first()if not user:return jsonify({'code': 200, 'message': '用户不存在'})if check_password_hash(user.password, password):# return jsonify({'code': 200, 'message': '用户登录成功'})# cookie 不适合存储太多数据，只适合存储少量的数据# seesionsession["user_id"] = user.idflash(f"用户：{user.username} 登录成功")return redirect("/")else:return redirect(url_for("auth.login"))else:log.error(form.errors)return redirect(url_for("auth.login"))
