如何使用符号访问HTTParty的JSON响应?

扰流板警告: 最好的选择是#3

选项1: 你可以打电话 .with_indifferent_access 在哈希上,可以使用 'link' 或 :link

{'a' => 1}[:a]
# => nil
{'a' => 1}.with_indifferent_access[:a]
# => 1
{'a' => 1}.with_indifferent_access['a']
# => 1

选项2: 呼叫 .symbolize_keys (或 .deep_symbolize_keys 如果您也想对嵌套键进行符号化),请将所有键转换为符号:

hash = { 'name' => 'Rob', 'address' => { 'postal_code' => '92210' } }
hash.symbolize_keys
# => {:name=>"Rob", :address=>{'postal_code'=>'92210'}}
hash.deep_symbolize_keys
# => {:name=>"Rob", :address=>{:postal_code=>'92210'}}

使用 symbolize_names 选项设置为 true

JSON.parse(string, symbolize_names: true)

通过深入搜索,我找到了一种更简洁的方法来解决这个问题。符号化_键!,例如:

order_status = JSON.parse(order.body).symbolize_keys![:status]
