这篇教程flask框架实现修改密码和免密登录功能写得很实用，希望能帮到您。
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})html页面： <!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>树懒电影---重置您的密码</title> <style type="text/css"> #resetform{ margin-top: 350px; margin-left: 750px; } </style></head><body> <form method="post" id="resetform"> <tr> <td><input type="text" id="userphone" value="" placeholder="输入您的手机号码"></td> </tr><br> <tr> <td><input type="password" id="resetpass1" value="" placeholder="输入您的新密码"></td> </tr><br> <tr> <td><input type="password" id="resetpass2" value="" placeholder="再次输入您的新密码"></td> </tr><br> <tr> <td><input type="reset" value="清空"></td> <td><input type="button" id="resetbtn" onclick="resetpass()" value="提交"></td> </tr> </form></body></html><script src="../static/js/jquery.min.js"></script><script type="text/javascript"> function resetpass(){ var userphone=document.getElementById("userphone").value var resetpass1=document.getElementById("resetpass1").value var resetpass2=document.getElementById("resetpass2").value var submit_flag=1 //判空 if((userphone.length==0)||(resetpass1.length==0)||(resetpass2.length==0)){ submit_flag=0 alert("请把信息填写完整！") } //判断密码一致性 if(resetpass2!=resetpass1){ submit_flag=0 alert("两次填写的密码不一致") document.getElementById("resetpass1").focus(); } //判断手机号 if(userphone.length!=11){ submit_flag=0 alert("手机号码应为11位！") document.getElementById("userphone").focus(); } var regu = /^1[3456789]/d{9}$/ if(!(regu.test(userphone)) ){ submit_flag=0 alert("手机号码格式有误！") document.getElementById("userphone").focus(); } //判断密码格式 if(!((resetpass1.length>=6)&&resetpass1.length<=18)) { submit_flag=0 alert("密码长度应该为6-16位!") document.getElementById("resetpass1").focus(); } var regex = new RegExp('(?=.*[0-9])(?=.*[a-zA-Z]).{6,18}'); part_pass=resetpass1.split(" ") if((!(regex.test(resetpass1))) || part_pass.length!=1) { submit_flag=0 alert("密码为数字+英文字母 且不可以包含空格！") document.getElementById("resetpass1").focus(); } //发起请求 if(submit_flag==1) { $.ajax({ url:"/resetpass", data:{userphone:userphone,resetpass:resetpass2}, success: function (data) { if (data.data==1) { alert("密码修改成功！") window.open("/",'_self') } else { alert("修改密码失败！请重试") } }, error: function (xhr, type, errorThrown) { // print("ajax请求失败！") } }) } // alert(submit_flag) }</script>
