上面显示的字符串是为我的供应商编写的应用程序定制的 XML 文件的一部分。我可以访问 XML 但我不知道如何解码 file.Is 节点中包含的此类字符串 有一种方法可以对其进行解码 and/or 以了解应用了哪种编码是吗？
它是 64 进制数。
在 unix 上，您可以使用 base64 解码。
在 Windows，您可能需要编写脚本。
use strict;
use warnings;
use MIME::Base64 qw ( decode_base64 );
my $stuff = <DATA>;
open( my $output, ">", "something.out" );
#print decode_base64($stuff);
foreach ( split( //, decode_base64($stuff) ) ) {
printf( "%02x ", ord($_) );
print "\n" if $_ eq "\n";
}
根据您提供的内容，它解码为某种二进制数据类型。我不知道 that 应该是什么文件格式。
以字节模式开头：
1f 8b 08 00
其中指的是：http://www.garykessler.net/library/file_sigs.html
表示它是一个 gzip 压缩文件。
简单的方法就是将 something.out 另存为 something.gz 并使用您拥有的任何 gzip 工具。 （你也许可以用 IO::Uncompress::Gunzip 之类的东西来 perl 它）
我有这个字符串应该包含 XML 信息，但我不知道它是如何编码的。

上面显示的字符串是为我的供应商编写的应用程序定制的 XML 文件的一部分。我可以访问 XML 但我不知道如何解码 file.Is 节点中包含的此类字符串 有一种方法可以对其进行解码 and/or 以了解应用了哪种编码是吗？
它是 64 进制数。
在 unix 上，您可以使用 base64 解码。
在 Windows，您可能需要编写脚本。
use strict;
use warnings;
use MIME::Base64 qw ( decode_base64 );
my $stuff = <DATA>;
open( my $output, ">", "something.out" );
#print decode_base64($stuff);
foreach ( split( //, decode_base64($stuff) ) ) {
printf( "%02x ", ord($_) );
print "\n" if $_ eq "\n";
}
根据您提供的内容，它解码为某种二进制数据类型。我不知道 that 应该是什么文件格式。
以字节模式开头：
1f 8b 08 00
其中指的是：http://www.garykessler.net/library/file_sigs.html
表示它是一个 gzip 压缩文件。
简单的方法就是将 something.out 另存为 something.gz 并使用您拥有的任何 gzip 工具。 （你也许可以用 IO::Uncompress::Gunzip 之类的东西来 perl 它）
