ruby-on-rails - Ruby - 哈希、符号和字符串

Question

我有返回下一个哈希对象的 gem

{:response=>"There was an error authenticating the sender account.", :status_code=>401}

在我的 rake 任务中，我试图访问它的属性：

response = my_gem.execute
puts response
puts response.has_key?(:respose)
puts response[:respose]

但我不明白为什么会打印

{:response=>"There was an error authenticating the sender account.", :status_code=>401}
false

为什么我不能使用 response[:respose] 访问 :response 属性？

PS response[response.keys.first] 有效，但这是非常奇怪的解决方案

Answer 1

There is a typo in the below :

puts response.has_key?(:respose)

has_key?(:respose) should be has_key?(:response).

response = {:response=>"There was an error authenticating the sender account.", :status_code=>401}
response.has_key?(:response)
# => true
