本篇文章重点为大家讲解一下flask框架修改密码和免密登录具体方法，有需要的小伙伴可以参考一下。
修改密码功能
数据库部分：
#重置密码
def reset_pass(phone,password):
conn,cursor=get_conn()
sql="update userdata set userpass='"+password+"' where userphone='"+phone+"'"
try:
print("正在修改密码...")
resetflag=cursor.execute(sql)
conn.commit()
close_conn(conn,cursor)
if(resetflag==1):
print("修改成功")
return 1
else:
print("修改失败！")
return 0
except:
print("系统错误...修改密码失败！")
return 0
路由部分：
#用户修改密码
@app.route('/resetpass',methods=['GET', 'POST'])
def resetpass():
userphone=request.values.get('userphone')
resetpass=request.values.get('resetpass')
print("路由获得手机号："+userphone+"\n")
print("路由获得新密码：" + resetpass + "\n")
flag=sql.reset_pass(userphone,resetpass)
if(flag==1):
return jsonify({"data":1})
else:
return jsonify({"data":0})

Python路由
#免密登录
@app.route('/web_login/',methods=['GET', 'POST'])
def web_login():
userphone = request.values.get('userphone')
password=request.values.get('password')
cb=request.values.get('cb')
print("是否记住密码： "+cb) #cb的返回值类型是 str 字符串
# print(type(cb))
print("登录账号："+userphone+" "+"密码："+password)
res=sql.web_login(userphone,password)
if(res==True):
session['userphone'] = userphone
if(cb=="1"):
print("开始存储cookie登录账号：" + userphone + " " + "密码：" + password)
resp = make_response('储存cookie')
resp.set_cookie('cookphone', userphone, max_age=3600 * 24 * 15)
resp.set_cookie('cookpass', password, max_age=3600 * 24 * 15)
print("登录成功且用户选择记住密码，返回response")
return resp #登录成功且用户选择记住密码，返回response
else:
print("登录成功 返回 1 状态码")
return jsonify({"data": 1}) # 登录成功 返回 1 状态码
else:
print("登录失败 返回 0 状态码")
return jsonify({"data":0}) #登录失败 返回 0 状态码数据库验证登录
# 用户（web）登录验证
def web_login(userphone, password):
cursor = None
conn = None
res=[]
if(userphone==None or password==None):
return False
conn, cursor = get_conn()
sql = "select userphone,userpass from userdata where '"+userphone+"'=userphone and '"+password+"'=userpass "
res=query(sql)
conn.commit()
if(len(res)==0):
print("登陆失败（WEB）")
close_conn(conn, cursor)
return False
else:
close_conn(conn, cursor)
print("登陆成功（WEB）")
return True
