错误:在 URL php api 脚本中发现非法字符

Question

最近我升级了我的VPS服务器，以增加RAM和存储空间

升级后，我注意到我的付款 api 开始出现错误

Error: Illegal characters found in URL

我以前从未遇到过的，我的API用于处理付款已经运行多年，在我升级后仅在三月份停止

这是我目前使用的代码

<?php 
                /* $myparams = array();
                $myparams['subpdtid'] = #### ;

                $myparams['submittedamt'] = $_SESSION['amt4hash'] ;
                $myparams['rettxref'] = $_POST['txnref'] ;
                $myparams['retpayRef'] = $_POST['payRef'] ;
                $myparams['retretref'] = $_POST['retRef'] ;
                $myparams['retcardnum'] = $_POST['cardNum'] ;

请问谁能开导我？

Answer 1

这是因为您在字符串后附加不需要的n

将代码更改为

 $ponmo = http_build_query($parami);
        //$url = "https://stageserv.interswitchng.com/test_paydirect/api/v1/gettransaction.xml?$ponmo";// xml
        $url = "https://webpay.interswitchng.com/paydirect/api/v1/gettransaction.json?$ponmo"; // json
