谁能看懂JS这个代码帮我实现下API POST

},
});
$('#rootwizard').bootstrapWizard('disable', 2);

$('.buy_card_btn').click(function() {
$('#rootwizard').find("a[href*='tab2']").trigger('click');
window.open(key_url, "_blank", "height=600,width=800,scrollbars=yes,resizable=1,modal=false,alwaysRaised=yes");
});

$(".recharge-btn").click(function () {
var _this = this
$(".card_msg").hide()
var cardno = $.trim($("input[name='cardno']").val())
if (cardno === ''){
$(".card_msg").show()
return false;
}
$(_this).find("span").text("充值中...")
$(_this).prop("disabled", true);
$('#rootwizard').bootstrapWizard('enable', 2);

}

})

谁能看懂，我有token，卡密，想通过API post GET等方式进行充值

该怎么写PHP代码来写

第一步要先调用/user_get_recharge_key?token=。。。获取ticks

第二步才是调用user_recharge_wallet接口，并且调用接口还少了个signature参数，最好能发对方网站出来，里面有个js方法$.md5，不知道是否和php的md5加密一致，如果是的用md5计算签名后附加上才行

你的key不知道从哪里来的，这个key是调用第一个接口后返回的，不知道是否会变，最好是通过接口重新获取key，代码大概如下，就差$.md5加密后的值是否和php的md5一致，一致应该就没什么问题了

如果你确认key没有问题可以去掉第一步接口调用

<?php error_reporting(0);
$token=$_GET['token'];
$cardno=$_GET['cardno'];


$ticks=file_get_contents("http://adm.fxtcvip.com/user_get_recharge_key?token=$token");//先获取ticks
$o=json_decode($ticks);
if($o->code!==0)die("ticks获取出错<br>".$ticks);

$ticks=$o->data;
$signature =$ticks . $token . $cardno;

$signature =md5($signature);//计算签名


$contents =file_get_contents("http://adm.fxtcvip.com/user_recharge_wallet?token=$token&cardno=$cardno&key=$ticks&signature=$signature");
 
echo $contents;
?>

以下肯定不成功，以上是对方网站的JS文件，我看不懂，对照以上JS文件， 以下这个PHP应该怎么提交，这些参数才是正确的 


<?php error_reporting(0);

$token=$_GET['token'];

$cardno=$_GET['cardno'];

$key=$_GET['key'];

$handle = fopen ("http://adm.fxtcvip.com/user_recharge_wallet?token=$token&cardno=$cardno&key=$key", "rb");

$contents = "";

do {

$data = fread($handle, 1024);

if (strlen($data) == 0) {

break;

$contents.= $data;

} while(true);

fclose ($handle);

echo $contents;

/**
* jQuery MD5 hash algorithm function
* 
* <code>
* Calculate the md5 hash of a String 
* String $.md5 ( String str )
* </code>
* 
* Calculates the MD5 hash of str using the 禄 RSA Data Security, Inc. MD5 Message-Digest Algorithm, and returns that hash. 
* MD5 (Message-Digest algorithm 5) is a widely-used cryptographic hash function with a 128-bit hash value. MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of data. The generated hash is also non-reversable. Data cannot be retrieved from the message digest, the digest uniquely identifies the data.
* MD5 was developed by Professor Ronald L. Rivest in 1994. Its 128 bit (16 byte) message digest makes it a faster implementation than SHA-1.
* This script is used to process a variable length message into a fixed-length output of 128 bits using the MD5 algorithm. It is fully compatible with UTF-8 encoding. It is very useful when u want to transfer encrypted passwords over the internet. If you plan using UTF-8 encoding in your project don't forget to set the page encoding to UTF-8 (Content-Type meta tag). 
* This function orginally get from the WebToolkit and rewrite for using as the jQuery plugin.
* 
* Example
* Code
* <code>
* $.md5("I'm Persian."); 
* </code>
* Result
* <code>
* "b8c901d0f02223f9761016cfff9d68df"
* </code>

jquery.md5.js

对我也看了最后是个 signature 这个好像是

var signature = $.md5(ticks + token + cardno); 需要这个3个=MD5 =signature

不知道我这样理解得对不对

http://adm.fxtcvip.com/user_get_recharge_key?token=6Mi5YBNWcTXBWtgE1616181050589 这里能得到一个

{"code":0,"data":"1616230814363713","msg":"\u6210\u529f"}   发现这个码是动态的，一会要变的，好像需要每次及时调用，不知道我理解错没，，大哥你帮我看下这个该怎么写，！！！还是你能理解我，感激！！！！！！！！！！！

第一步要先调用/user_get_recharge_key?token=。。。获取ticks

如果你确认key没有问题可以去掉第一步接口调用
