我如何URI::encode
像这样的字符串:
\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a
以如下格式获取它:
%124Vx%9A%BC%DE%F1%23Eg%89%AB%CD%EF%124Vx%9A
根据RFC 1738?
这是我尝试过的:
irb(main):123:0> URI::encode "\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a"
ArgumentError: invalid byte sequence in UTF-8
from /usr/local/lib/ruby/1.9.1/uri/common.rb:219:in `gsub'
from /usr/local/lib/ruby/1.9.1/uri/common.rb:219:in `escape'
from /usr/local/lib/ruby/1.9.1/uri/common.rb:505:in `escape'
from (irb):123
from /usr/local/bin/irb:12:in `<main>'
也:
irb(main):126:0> CGI::escape "\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a"

我四处寻找有关互联网的信息,但还没有找到解决方法,尽管我几乎肯定地说,前几天我做到了这一点,没有任何麻烦。
