我怎样才能访问这个哈希？

Question

我有这个哈希：

{
  "EnviarInstrucaoUnicaResponse"=>{
    "xmlns:ns1" => "http://www.moip.com.br/ws/alpha/",
    "Resposta" => {
      "ID"=>"201504171610223590000007515979",
      "Status"=>"Sucesso",
        "Token"=>"Y2F0P1R5G0D4Y1E7A196I1T0O252Z325U9H040M0E0G0Y0V7F581457957X9"
    }
  }
}

如何访问里面的"Token"？

我试过了<%= @token[EnviarInstrucaoUnicaResponse] %> ....

Answer 1

让

Your_Hash = {
  "EnviarInstrucaoUnicaResponse"=>{
    "xmlns:ns1" => "http://www.moip.com.br/ws/alpha/",
    "Resposta" => {
      "ID"=>"201504171610223590000007515979",
      "Status"=>"Sucesso",
        "Token"=>"Y2F0P1R5G0D4Y1E7A196I1T0O252Z325U9H040M0E0G0Y0V7F581457957X9"
    }
  }
}

然后

Token = Your_Hash['EnviarInstrucaoUnicaResponse']['Resposta']['Token']

所以你需要做的是：<%= @token[EnviarInstrucaoUnicaResponse]['Resposta']['Token'] %>

Answer 2

就像你使用哈希一样：

@token["EnviarInstrucaoUnicaResponse"]["Reposta"]["Token"]

您的示例是无效的 Ruby 代码。您需要将键指定为字符串。其他语言会自动为您转换，例如 Perl，但不会 Ruby.
