決議哈希時丟失了位，實際上我想檢索"HTTP get traffic"在這種情況下的 id 9.? 誰能幫忙？
gettest = {
"Groups" => [
{
"GroupName" => {"TextId" => "Hardware"},
"Tests" => [
{"Description"=>{"TextId"=>"ODU current measurement"}, "Id" => 0}
]
},
{
"GroupName"=>{"TextId"=>"LAN"},
"Tests" => [
{"Description" => {"TextId" => "Ethernet status"}, "Id" => 2},
{"Description" => {"TextId" => "Number of TCP Sessions"}, "Id" => 3}
]
},
{
"GroupName" => {"TextId" => "Satellite connection"},
"Tests" => [
{"Description" => {"TextId" => "Physical layer status"}, "Id" => 4},
{"Description" => {"TextId" => "Data link layer status"}, "Id" => 5},
{"Description" => {"TextId" => "Network layer status"}, "Id" => 6}
]
},
{
"GroupName" => {"TextId" => "Software"},
"Tests" => [
{"Description" => {"TextId" => "Software"}, "Id" => 1}
]
},
{
"GroupName" => {"TextId" => "Traffic"},
"Tests" => [
{"Description" => {"TextId" => "Ping traffic"}, "Id" => 7},
{"Description" => {"TextId" => "DNS traffic"}, "Id" => 8},
{"Description" => {"TextId" => "HTTP get traffic"}, "Id" => 9}
]
}
]
}
uj5u.com熱心網友回復：
像這樣的東西？
traffic_group = gettest['Groups'].find do |group|
group['GroupName']['TextId'] == 'Traffic'
end
if traffic_group
http_get_traffic = traffic_group['Tests'].find do |test|
test['Description']['TextId'] == 'HTTP get traffic'
end
if http_get_traffic
http_get_traffic_id = http_get_traffic['Id']
puts "HTTP get traffic id: #{http_get_traffic_id}"
else
puts 'no http get traffic node found'
end
else
puts 'no traffic group found'
end
