ruby-on-rails - 如何在 Ruby 中对字符串进行 URL 编码

Question

我如何URI::encode一个像这样的字符串:

\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>'

还有:

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"
ArgumentError: invalid byte sequence in UTF-8
    from /usr/local/lib/ruby/1.9.1/cgi/util.rb:7:in `gsub'
    from /usr/local/lib/ruby/1.9.1/cgi/util.rb:7:in `escape'
    from (irb):126
    from /usr/local/bin/irb:12:in `<main>'

我在互联网上搜索了所有内容，但还没有找到执行此操作的方法，尽管我几乎可以肯定前几天我完全没有遇到任何问题。

str = "\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a".force_encoding('ASCII-8BIT')
puts CGI.escape str


=> "%124Vx%9A%BC%DE%F1%23Eg%89%AB%CD%EF%124Vx%9A"
