Rails通过API XML响应遍历哈希

本文介绍了Rails通过API XML响应遍历哈希的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述我使用Httparty从API获得了这个散列。响应是一个XML，但是httparty显示它是一个散列。但它太深了，得到这些值会令人困惑。 { air_search_result => {xmlns=> http://www.cleartrip.com/air/ ， onward_solutions => { solution => [{index=>1， pricing_summary => {base_fare=>3350.0 =>7828.55，total_fare=>11178.55}，航班=> {航班=> {=> {段=> [{index=>1，departure_airport=>BOM，arrival_airport=>BLR，departure_date_time =>2014-07-06T09：15：00，arrival_date_time=>2014-07-06T10：50：00，flight_number=>639，airline=>AI， operating_airline=>AI，stops=>0，equipment=>319，duration=>5700}，{index=>2 =BLR，arrival_airport=>DEL，arrival_terminal=>3，departure_date_time=>2014-07-06T20：10:00，arrival_date_time=>2014-07 -06T22：40：00，flight_numb er=>404，airline=>AI，operating_airline=>AI，stops=>0，equipment=>320，duration=> 9000}]}}}， pax_pricing_info_list => { pax_pricing_info => {pax_type=>ADT strong>=> { pricing_info => {index=>1，fare_basis_code=>SAP30，SAP30，........ 我需要进入并显示航空公司，departure_airport等。 flights=> {flight= > {segments=> {segment=> <％@flight [air_search_result] [onward_solutions ] [solution]。each do | h | ％GT; <％= h [pricing_summary] [total_fare]％> - <％= end％> 当我包含[airline]时，rails 4方便地说不能转换String整数。但我可以得到[pricing_summary] [total_fare] 我尝试了许多变化，嵌套循环但可惜，它不起作用。我也想知道是否有任何宝石或方法，可以直接给出结果而不是如此深的遍历编辑 <％@flight [air_search_result] [onward_solutions] [solution ] .map do | h | ％GT; <％= h [pricing_summary] [total_fare]％> - <％h [航班] [航班] [航段] [航段]。％GT; <％= s [航空公司]％> <％end％> < HR> <％end％> 解决方案查看 BroiSatse ：h [flights] [flight] [segments] [segment]是一个数组，不是散列。 $ p> <％@flight [air_search_result] [onward_solutions] [solution]。each do | h | ％GT; <％= h [pricing_summary] [total_fare]％> - <％= end％> 或第一个 <％h [flights] [flight] [segments] [segment]。first [airline]％> 或全部显示airline H [ 航班] [ 飞行] [ 段] [ 段]地图{|。S | s [airline]} ＃return：[AI，AI] 或显示连接分隔符 h [flights] [flight] [segments] [segment ] {.MAP | S | s [airline]}。join（'，'）或显示更多数据 <％@flight [air_search_result] [onward_solutions] [solution]。each do | h | ％GT; <％= h [pricing_summary] [total_fare]％> - <％=＃{s ['airline']}（＃{s ['flight_number']}）％> <％end％> <％= end％> 您可以在导轨控制台中检查。部分来自API响应： h = {flights=> {flight=> {segments=> {segment=> [{equipment=>319，stops=>0，duration=>5700，departure_date_time =2014-07-06T09：15：00，index=>1，airline=>AI，flight_number =639，arrival_date_time=>2014-07-06T10：50：00，arrival_airport=>BLR，departure_airport =>BOM，operating_airline=>AI}， {equipment=>320，stops=>0 ，duration=>9000，departure_date_time=>2014-07-06T20：10:00，arrival_terminal=>3 ，index=>2，airline=>AI，flight_number=>404，arrival_date_time =>2014-07-06T22：40：00，arrival_airport=>DEL，departure_airport=>BLR，operating_airline => 中AI}] }}}，index=>1，pricing_summary=> {taxes=>7828.55，base_fare=>3350.0，total_fare=>11178.55}} h [首先[航空公司]＃'AI' h [航班] [航段] [航段] [航段 ] [segment] [0] [airline]＃AI h [flights] [flight] [segments] [segment]。map { | S | s [airline]}。join（'，'）＃AI，AI h [flights] [flight] [segments] [segment]。each {| s | （639）＃AI（404） I have this hash that I received from an API, using Httparty. The response was an XML but httparty showed it as a hash. But it is soo deep, it gets confusing to get the values.{"air_search_result"=>{"xmlns"=>"http://www.cleartrip.com/air/", "onward_solutions"=>{"solution"=>[{"index"=>"1", "pricing_summary"=>{"base_fare"=>"3350.0", "taxes"=>"7828.55", "total_fare"=>"11178.55"}, "flights"=>{"flight"=>{"segments"=>{"segment"=>[{"index"=>"1", "departure_airport"=>"BOM", "arrival_airport"=>"BLR", "departure_date_time"=>"2014-07-06T09:15:00", "arrival_date_time"=>"2014-07-06T10:50:00", "flight_number"=>"639", "airline"=>"AI", "operating_airline"=>"AI", "stops"=>"0", "equipment"=>"319", "duration"=>"5700"}, {"index"=>"2", "departure_airport"=>"BLR", "arrival_airport"=>"DEL", "arrival_terminal"=>"3", "departure_date_time"=>"2014-07-06T20:10:00", "arrival_date_time"=>"2014-07-06T22:40:00", "flight_number"=>"404", "airline"=>"AI", "operating_airline"=>"AI", "stops"=>"0", "equipment"=>"320", "duration"=>"9000"}]}}}, "pax_pricing_info_list"=>{"pax_pricing_info"=>{"pax_type"=>"ADT", "pricing_info_list"=>{"pricing_info"=>{"index"=>"1", "fare_basis_code"=>"SAP30,SAP30", ........I need to get inside and show airline, departure_airport, etc."flights"=>{"flight"=>{"segments"=>{"segment"=><% @flight["air_search_result"]["onward_solutions"]["solution"].each do|h| %><%=h["pricing_summary"]["total_fare"] %> - <% h["flights"]["flight"]["segments"]["segment"] %><%= end %>When I include ["airline"], rails 4 conviniently says can't convert String into Integer.
