结果是8421877dd9cdf7235eec47765821998c结果是，无论客户机在做什么，都会导致数据本身发生更改，从而使其具有“\c\n”行结尾，并且在散列后，还会通过填充（末尾的空格）使文件中的行大小相同。一旦我们让客户端停止向我们提供坏数据，我们就能够复制散列。谢谢你的帮助 你能用Oracle中的函数在UTF-8中编码AL32UTF8字符吗？我猜你误解了这篇文章。UTF8有点奇怪，但与您的问题无关。Oracle的AL32UTF8在其他地方被称为UTF-8。请显示您的代码并显示一个示例。ASCII和UTF-8中的相同字符之间没有字节对字节的差异。@Ben-我们自己没有oracle。它来自一个使用oracle的客户机。Codo-I添加了代码和示例
