从 Ruby MAP 获取键和值

Question

我想使用 Ruby MAP 来获取数据：

PAYMENT_TYPE_TO_CURRENCY_AND_COUNTRY_MAPPING = {
zimpler:              { 'EUR' => ['FI'], 'SEK' => ['SE'] },
qiwi:                 { 'EUR' => ['RU', 'KZ'], 'RUB' => ['RU'], 'KZT' => ['KZ'], 'USD' => ['UA'] },
payu:                 { 'CZK' => ['CZ'], 'PLN' => ['PL']},
entercash:            { 'EUR' => ['AT', 'DE', 'FI'], 'SEK' => ['SE'] },
carulla:              { 'USD' => ['CO'] }
}

我想使用MAP中的上述数据创建存根：

GirogateRequestBuilder::PAYMENT_TYPE_TO_CURRENCY_AND_COUNTRY_MAPPING.keys.each do |payment_method|
stub_request(:post, /.*/).
with(:body => "<?xml version="1.0" encoding="UTF-8"?>n
<payment_transaction>n  
<transaction_type>#{payment_method.key}</transaction_type>n  
<transaction_id>/.*/</transaction_id>n  
<usage>New iPad</usage>n  
<currency>#{payment_method.get here currency}</currency>n  
<billing_address>n    
<first_name>Barney</first_name>n    
<country>#{payment_method.get here country}</country>n    
<state/>n  
</billing_address>n           
:headers => {'Accept'=>'*/*', 'Authorization'=>/.*/, 'Cache-Control'=>'no-cache', 'Content-Type'=>'application/xml'})
.to_return(status: 200, body: successful_response_file)
end

如何从地图中获取正确的值？

Answer 1

只需使用PAYMENT_TYPE_TO_CURRENCY_AND_COUNTRY_MAPPING.each do |key, value|：

PAYMENT_TYPE_TO_CURRENCY_AND_COUNTRY_MAPPING.each do |key, value|
# key = :zimpler
# value = { 'EUR' => ['FI'], 'SEK' => ['SE'] }
