Ruby - URL编码

Question

我有一个URL字符串,其中有换行符和回车符.例如

http://xyz.com/hello?name=john&msg=hello\nJohn\n\rgoodmorning&note=last\night I went to \roger

我的实际msg字符串是:

hello
john
goodmorning

和note字符串是

last\night I went to \roger

为了正确发送它我必须urlencode这个

 http://xyz.com/hello?name%3Djohn%26msg%3Dhello%5CnJohn%5Cn%5Crgoodmorning%26note%3Dlast%5Cnight%20I%20went%20to%20%5Croger

但这个编码搞乱\n和\ r.虽然我希望\n应该转换为%0A和\ r转换为%0D

我写的代码是ruby.我试图帮助Addressable::URI但没有帮助.其他方式可以分别手动将\n和\ r \n替换为%0A和%0D.但是,置换能代替有效的字符,如last\night到last%0Aight,我不想要的.有谁能建议更好的解决方案？谢谢.

Answer 1

关于什么 CGI::escape

您只需要编码参数.

url = "http://xyz.com/hello?"
params = "name=john&msg=hello\nJohn\n\rgoodmorning&note=last\night I went to \roger"

puts "#{url}#{CGI::escape(params)}"
# => "http://xyz.com/hello?name%3Djohn%26msg%3Dhello%0AJohn%0A%0Dgoodmorning%26note%3Dlast%0Aight+I+went+to+%0Doger"
