我的问题是代码行'$encyptedRow=$rowP->decryptRow($row(；'
在那里我会收到一条错误消息，类似于：
'Uncaught TypeError:传递给ParagonIE\ConstantTime\Binary:：safeSubstr((的参数1必须是字符串类型，给定null，在C:\Users中调用。。。\vendor\progonie\ciphersweet\src\Backend\FIPSCrypto.php在第95行，并在C:\Users中定义。。。\vendor\paragonie\constant_time_encoding\src\Binary.php：67堆栈跟踪：#0 C:\Users。。。\vendor\pragonie\ciphersweet\src\Backend\FIPSCrypto.php(95(：paragonie\ConstantTime\Binary:：safeSubst(NULL，0，5(#1 C:\用户。。。\vendor\pragonie\ciphersweet\src\EncryptedRow.php(334(：paragonie\ciphersweet\Backend\FIPSCrypto->解密(NULL，对象(ParagonIE\CipherSweet\Backend\Key\SymmetricKey(#2 C:\用户。。。\partials\cherTEST.php(94(：ParagonIE\CipherSweet\EncryptedRow->decryptRow(数组(#3 C:\用户…'
也许有人能帮我。
非常感谢。
我得到了它。我的错误是通过将select语句的结果作为索引数组
$row = $result->fetch_row();
但函数decryptRow需要一个带有字段名的关联数组。所以代码必须像一样
$row = $result->fetch_assoc();
现在函数decryptRow将获得用于处理代码行的字段名
$plaintext = $backend->decrypt($row[$field], $key);
最后，它运行得很好。
异常是由于null在此处传递给decrypt()：https://github.com/paragonie/ciphersweet/blob/f73aaea31f743dad8145f344d93503c4d9f950a8/src/EncryptedRow.php#L334。要么$row[$field]包含null，要么$row中没有这样的元素。
使用调试器对其进行检查，或者在catch(例如var_dump($rowP, $row)(中添加一些调试语句，然后检查$row中包含的数据是否符合您的预期。还值得检查$rowP->fieldsToEncrypt中的字段列表。
