驗證更改密碼的表單 ``` class ResetpwdForm(BaseForm): oldpwd = StringField(validators=[Length(6,20,message="請輸入正確格式的密碼")]) newpwd = StringField(validators=[Length(6,20,message="請輸入正確格式的密碼")]) newpwd2 = StringField(validators=[EqualTo("newpwd")]) ``` 判斷更改密碼的信息 ``` def post(self): form = ResetpwdForm(request.form) if form.validate(): # 獲取密碼信息 oldpwd = form.oldpwd.data newpwd = form.newpwd.data # 獲取全局對象g的用戶屬性 user = g.cms_user # 判斷原密碼是否一致 if user.check_password(oldpwd): # 修改密碼 user.password = newpwd # 提交到數據庫中 db.session.commit() # 返回數據 return jsonify({"code":200,"message":""}) else: return jsonify({"code":400,"message":"舊密碼錯誤"}) else: message = form.get_error() return jsonify({'code':400,"message":message}) ```
