Optimize client calls to server interfaces to reduce request data capacity
Optimize client calls to server interfaces to reduce request data capacity
Due to project needs, it is necessary to record the user's reservation time in the next three days, and each reservation period is 1 hour.
For example: 00:00:00～00:59:59 or 01:00:00～01:59:59 etc. is a reservation period
The front-end code is as follows:
nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<meta>
<title> 提交预约日期 </title>
<style>
.title{color:#FF0000;}
.topic{font-size:18px; font-weight:bold;}
</style>
<script></script>
<script> function fsubmit(){
var timetable = [];
$("#myform input[type=checkbox]").each(function(){ if(this.checked){
timetable.push($(this).val());
}
}); if(timetable.length==0){
alert('请选择预约时间');
return false;
}
$.post("http://localhost/server.php",{timetable:timetable}).done(function(data){ if(data['success']==true){
alert('提交成功');
}else{
alert('提交失败');
}
});
}
</script>
<p>请选择预约时间：</p>
The back-end code is as follows:
<?php $data = $_POST['timetable']; file_put_contents('timetable.log', json_encode($data)); header('content-type:applicaiton/json;charset=utf8');echo json_encode(array('success'=>true));?>
For example, to submit a user's 3 Day reservation data, reservations for all time periods (select all)
The request data received by the backend is as follows:
["2015-05-28 00:00:00","2015-05-28 01:00:00","2015-05-28 02:00:00","2015-05-28 03:00:00","2015-05-28 04:00:00","2015-05-28 05:00:00","2015-05-28 06:00:00","2015-05-28 07:00:00","2015-05-28 08:00:00","2015-05-28 09:00:00","2015-05-28 10:00:00","2015-05-28 11:00:00","2015-05-28 12:00:00","2015-05-28 13:00:00","2015-05-28 14:00:00","2015-05-28 15:00:00","2015-05-28 16:00:00","2015-05-28 17:00:00","2015-05-28 18:00:00","2015-05-28 19:00:00","2015-05-28 20:00:00","2015-05-28 21:00:00","2015-05-28 22:00:00","2015-05-28 23:00:00","2015-05-29 00:00:00","2015-05-29 01:00:00","2015-05-29 02:00:00","2015-05-29 03:00:00","2015-05-29 04:00:00","2015-05-29 05:00:00","2015-05-29 06:00:00","2015-05-29 07:00:00","2015-05-29 08:00:00","2015-05-29 09:00:00","2015-05-29 10:00:00","2015-05-29 11:00:00","2015-05-29 12:00:00","2015-05-29 13:00:00","2015-05-29 14:00:00","2015-05-29 15:00:00","2015-05-29 16:00:00","2015-05-29 17:00:00","2015-05-29 18:00:00","2015-05-29 19:00:00","2015-05-29 20:00:00","2015-05-29 21:00:00","2015-05-29 22:00:00","2015-05-29 23:00:00","2015-05-30 00:00:00","2015-05-30 01:00:00","2015-05-30 02:00:00","2015-05-30 03:00:00","2015-05-30 04:00:00","2015-05-30 05:00:00","2015-05-30 06:00:00","2015-05-30 07:00:00","2015-05-30 08:00:00","2015-05-30 09:00:00","2015-05-30 10:00:00","2015-05-30 11:00:00","2015-05-30 12:00:00","2015-05-30 13:00:00","2015-05-30 14:00:00","2015-05-30 15:00:00","2015-05-30 16:00:00","2015-05-30 17:00:00","2015-05-30 18:00:00","2015-05-30 19:00:00","2015-05-30 20:00:00","2015-05-30 21:00:00","2015-05-30 22:00:00","2015-05-30 23:00:00"]
Request data content- length:2879
Using this method to request a larger data capacity will affect the response time.
Improvement method 1: Convert the DateTime format time to a timestamp and then submit
The front-end code is modified as follows: Modify the javascript fsubmit method
<script type="text/javascript">
function fsubmit(){
var timetable = [];
$("#myform input[type=checkbox]").each(function(){
if(this.checked){ // 把时间转为时间戳
var time = $(this).val(); var timestamp = Date.parse(new Date(time));
timestamp = timestamp / 1000;
timetable.push(timestamp);
}
}); if(timetable.length==0){
alert('请选择预约时间'); return false;
}
$.post("http://localhost/server.php",{timetable:timetable}).done(function(data){
if(data['success']==true){
alert('提交成功');
}else{
alert('提交失败');
}
});

After receiving it, the backend can convert the timestamp into datetime format for use
starting from right to left: 00:00, 01:00, 02:00 ,03:00 and so on, if there is a selected time period, it will be 1, otherwise it will be 0

The front-end code is modified as follows: Modify the javascript fsubmit method
<script type="text/javascript">
function fsubmit(){
var timetable = []; var tmp = {};
$("#myform input[type=checkbox]").each(function(){
if(this.checked){ // 拆分日期与时间
var datetime = $(this).val(); var datetime = datetime.split(' '); var day = datetime[0]; var time = parseInt(datetime[1].substring(0,2)); // 创建日期与时间数组
if(typeof(tmp[day])=='undefined'){

}); // 合拼数据，转换格式
for(day in tmp){ // 根据数据集合，合拼，创建10进制数据
var time = tmp[day]; var timeint = 0; for(var i=0; i<time.length; i++){

});
} </script>The request received by the backend The data is as follows:

Use this Method, no matter how many reservation time periods are selected in a day, there will only be one record, which greatly reduces the size of submitted data.
Backend method of converting decimal to time: 1. Convert decimal to binary and reverse
2. Loop through each bit and record the value of 1
3. Save the record
The code is as follows:
<?php$datetime = '2015-05-28 1398016';list($day, $time) = explode(' ', $datetime);$bintime = decbin($time);$bintime = strrev($bintime);$result = array();for($i=0,$len=strlen($bintime); $i<$len; $i++){ if(substr($bintime, $i, 1)==1){ $result[] = $day.' '.str_pad($i, 2, '0', STR_PAD_LEFT).':00:00';
}
}
print_r($result);?>Output:
Array(
[0] => 2015-05-28 08:00:00
[1] => 2015-05-28 10:00:00
[2] => 2015-05-28 12:00:00
[3] => 2015-05-28 14:00:00
[4] => 2015-05-28 16:00:00
[5] => 2015-05-28 18:00:00
[6] => 2015-05-28 20:00:00)Summary: This article provides a method that can convert large amounts of data into small-capacity data transmission, but it requires adding more operations. Therefore, in actual development, it is necessary to judge whether the algorithm of exchanging time for space or space for time is suitable based on actual needs.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
