Ruby 如何分别打印我的CLI项目的名称和URL

我在做吉他。我将吉他的名称和URL放在一个哈希数组中：

def self.get_electric
        doc = Nokogiri::HTML(open("https://reverb.com/c/electric-guitars"))

        electrics = []
        counter = 0

        while counter < doc.css("h2:contains('Popular Electric Guitars')+div.overflowing-row_items    ul.tiles.tiles--single-row.tiles--grow.tiles--three-wide li.tiles_tile").length
        electric = {
            name: doc.css("h2:contains('Popular Electric Guitars')+div.overflowing-row_items ul.tiles.tiles--single-row.tiles--grow.tiles--three-wide li.tiles_tile")[counter].text,
            url: doc.css("h2:contains('Popular Electric Guitars')+div.overflowing-row_items ul.tiles.tiles--single-row.tiles--grow.tiles--three-wide li.tiles_tile a.marketing-callout__inner")[counter]["href"]
        }
        counter += 1
        electrics << electric
        end
        electrics
    end

    def self.get_acoustic
        doc = Nokogiri::HTML(open("https://reverb.com/c/acoustic-guitars"))

        acoustics = []
        counter = 0

        while counter < doc.css("h2:contains('Popular in Acoustic Guitars')+div.overflowing-row_items ul.tiles.tiles--single-row.tiles--grow.tiles--three-wide li.tiles_tile").length
            acoustic = {
                name: doc.css("h2:contains('Popular in Acoustic Guitars')+div.overflowing-row_items ul.tiles.tiles--single-row.tiles--grow.tiles--three-wide li.tiles_tile")[counter].text,
                url: doc.css("h2:contains('Popular in Acoustic Guitars')+div.overflowing-row_items ul.tiles.tiles--single-row.tiles--grow.tiles--three-wide li.tiles_tile a.marketing-callout__inner")[counter]["href"]
            }
            counter += 1
            acoustics << acoustic
        end
        acoustics
    end

当我输入

.name

时，我得到：

/Users/tlreigns/RoyalTerminal/hi_strung/lib/hi_strung/cli.rb:43:in `block in menu': undefined method `name' for #<Hash:0x00007fab93b96a40> (NoMethodError)

{:name=>"Fender Telecaster", :url=>"https://reverb.com/marketplace/electric-guitars?query=telecaster"}
{:name=>"Gibson Les Paul", :url=>"https://reverb.com/marketplace?query=les%20paul"}
{:name=>"Fender Stratocaster", :url=>"https://reverb.com/marketplace/electric-guitars?query=stratocaster"}
{:name=>"Gibson SG", :url=>"https://reverb.com/marketplace?query=sg"}
{:name=>"Fender Jazzmaster", :url=>"https://reverb.com/marketplace?query=jazzmaster"}

如何分别获取名称和URL？

electrics的每个元素都是散列。您只需要值，而不是键值对

所以，我相信你只需要

puts electric[:name]

及

（如Amit Patel在评论中指出的那样，不使用字符串插值可以获得所需的输出。

Ahhh成功了，谢谢！还没有真正使用哈希，所以这对我来说是个新手！谢谢你！！字符串插值

“#{}”

不是必需的

put

可以打印任何类型的对象。所以，

put electric[：url]

足够打印字符串了。@AmitPatel啊，是的，你当然是对的。我只是复制和修改OP的格式，没有真正思考。谢谢

puts electric[:name]

puts electric[:url]
