【已解决】Base64编解码不准确，求解！
本帖最后由 xowen 于 2017-3-29 15:37 编辑#include <ACN_HASH.au3>
$var='cn=测 试,ou=gsphonebook,dc=sz,dc=com'
ConsoleWrite(_Base64Encode($var))运行完成后输出的字符串为：Y249suIgytQsb3U9Z3NwaG9uZWJvb2ssZGM9c3osZGM9Yw==
通过http://www1.tc711.com/tool/BASE64.htm网站进行Base64编解码时，
cn=测 试,ou=gsphonebook,dc=sz,dc=com输出为：
Y2495rWLIOivlSxvdT1nc3Bob25lYm9vayxkYz1zeixkYz1jb20=
使用网站上的Base64编码后，Openldap可以正常识别，但通过AutoIT生成的Base64无法识别。
另外，将网站成本的Base64通过Autoit解码后为：
cn=娴?璇?ou=gsphonebook,dc=sz,dc=com=>中文乱码。
论坛中看到如下使用方法：
_Base64Encode(StringToBinary($var))
但编码后还是和网上不一致。
AutoIT带的函数库有问题么？如果和网上的同步编解码出同样的字符串？ MsgBox(0,"",base64('cn=测 试,ou=gsphonebook,dc=sz,dc=com'))

其实做一下编码转换就好了，懒得写。直接调用js吧
RE: Base64编解码不准确，求解！【已解决】
回复 2# gto250明白了，使用StringToBinary时，标志参数使用4即可转码。谢谢！ 编码不一致吧！
