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，我正试图访问它的属性：

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

但我无法理解为什么打印

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

为什么我无法访问：带有响应的响应属性[：respose]？

P.S。响应[response.keys.first]有效，但这是非常奇怪的解决方案

Answer 1

下面有一个拼写错误：

puts response.has_key?(:respose)

has_key?(:respose)应为has_key?(:response)。

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