Rails通过API XML响应遍历哈希 [英] Rails traverse hash from API XML response
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=>< a href =http://www.cleartrip.com/air/ =nofollow> 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;
< strong><％= h [pricing_summary] [total_fare]％>< / strong> -
<％h [航班] [航班] [航段] [[[航段]]％>
<％= 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

查看 BroiSatse ：h [flights] [flight] [segments] [segment]是一个数组，不是散列。 $ p> 或第一个 或全部显示airline 或显示连接分隔符 或显示更多数据 您可以在导轨控制台中检查。部分来自API响应： 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"=> When I include ["airline"], rails 4 conviniently says can't convert String into Integer. But I can get ["pricing_summary"]["total_fare"] I am also wondering if there is any gem or method which can directly
give the result instead of such deep traversing EDIT
see the comment from "BroiSatse": "h["flights"]["flight"]["segments"]["segment"] is an array, not a hash." or with first or show all "airline" or show join separator or show more data You can check in the rails console. Part from API response:
