Question

我正在尝试使用Ruby解析复杂的JSON对象：

"data": [{
    "resourceId": 381,
    "resourceName": "Admin.Config",
    "resourceDesc": "Correspondence Admin -> Configuration",
    "permissions": [{
        "id": 1081,
        "operation": "Update",
        "assignedToRoleFlag": false
    }, {
        "id": 1071,
        "operation": "Read",
        "assignedToRoleFlag": false
    }],
    "productName": "Doc"
}, {
    "resourceId": 391,
    "resourceName": "Admin.Usage",
    "resourceDesc": "Correspondence Admin -> Usage",
    "permissions": [{
        "id": 1091,
        "operation": "Read",
        "assignedToRoleFlag": false
    }],
    "productName": "Doc"
}, ......................................     }

问题是，我想解析一下，以['data']['permissions']['id']为例['data']['resourceName'] = Admin.Config和['data']['permissions']['operation'] = Read。

我正在尝试获取此值（perm =上面的JSON响应）：

#!/usr/bin/env ruby
 require 'json'

perm = response.body
file = perm
data_hash = JSON.parse(file)
data_you_want = data_hash["data"].detect do |h|
h["resourceName"] == "Admin.Config" and h["permissions"][0]["operation"] == "Read"
end
permid = data_you_want['permissions'][0]['id']
puts permid

更简单的解决方案：

 guidz=[]
file = perm
data_hash = JSON.parse(file)
data_you_want = data_hash["data"].detect do |h|
puts h['permissions']
   if h["resourceName"] == "Admin.Config"
       h["permissions"].each do |permisiune|
           guidz << permisiune['id'] if permisiune['operation'] == 'Read'
           guidz << permisiune['id'] if permisiune['operation'] == 'Update'
      end
 end
    if h["resourceName"] == "Admin.Usage"
         h["permissions"].each do |permisiune|
           guidz << permisiune['id'] if permisiune['operation'] == 'Read'
        end
    end
end
puts guidz.inspect

如何在key1 = value1和key2 = value2的地方获取JSON值
