Question

我正在针对我转换为哈希的API XML响应编写测试。然而，哈希是嵌套的，所以它似乎表现得像“提供”是关键，其他一切都是值。（如下所示）

我希望能够访问此哈希中的键值对，以便我可以使用针对“Id”，“Count”等的rspec测试进行断言。谢谢

{"Offer"=>
  {"href"=>"http://xyz",
   "links"=>nil,
   "Id"=>"1501507",
   "Count"=>"5",
   "Collected"=>"3",
   "Status"=>"INPROGRESS"}}

Answer 1

还有#dig http://ruby-doc.org/core-2.3.0_preview1/Hash.html#method-i-dig

hash = {
  "Offer"=> { 
    "href"      => "http://xyz",
    "links"     =>  nil,
    "Id"        => "1501507",
    "Count"     => "5",
    "Collected" => "3",
    "Status"    => "INPROGRESS" 
  } 
}

puts hash.dig("Offer", "href")
# => http://xyz

Answer 2

如果

hash = { "Offer"=> { "href"      => "http://xyz",
                     "links"     =>  nil,
                     "Id"        => "1501507",
                     "Count"     => "5",
                     "Collected" => "3",
                     "Status"    => "INPROGRESS" } }

然后你可以使用这种表示法：

hash["Offer"]["href"] #=> "http://xyz"

或定义新哈希并使用常规哈希访问：

new_hash = hash["Offer"]
new_hash #=>
# { "href"      => "http://xyz",
#   "links"     => nil,
#   "Id"        => "1501507",
#   "Count"     => "5",
#   "Collected" => "3",
#   "Status"    => "INPROGRESS" }

new_hash["href"] #=> "http://xyz"

使用Ruby访问散列内哈希中的键值对
