在散列中选择值

Question

我从Ripe得到了这个JSON输出。

[ 
    {"name"=>"organisation", "value"=>"ORG-MI1-RIPE"}, 
    {"name"=>"org-name", "value"=>"Mira Internetsolutions ApS"}, 
    {"name"=>"org-type", "value"=>"LIR"}, 
    {"name"=>"address", "value"=>"Mira Internetsolutions ApS Nybovej 19 DK-7500 Holstebro Denmark"}, 
    {"name"=>"phone", "value"=>"+45 9610 1510"}, 
    {"name"=>"fax-no", "value"=>"+45 9610 1511"}, 
    {"name"=>"admin-c", "value"=>"MIA3-RIPE", "referenced-type"=>"person-role", "link"=>{"xlink:type"=>"locator", "xlink:href"=>"http://apps.db.ripe.net/whois/lookup/ripe/person-role/MIA3-RIPE"}}, 
    {"name"=>"admin-c", "value"=>"MIA3-RIPE", "referenced-type"=>"person-role", "link"=>{"xlink:type"=>"locator", "xlink:href"=>"http://apps.db.ripe.net/whois/lookup/ripe/person-role/MIA3-RIPE"}}, 
    {"name"=>"mnt-ref", "value"=>"rh-mira", "referenced-type"=>"mntner", "link"=>{"xlink:type"=>"locator", "xlink:href"=>"http://apps.db.ripe.net/whois/lookup/ripe/mntner/rh-mira"}}, 
    {"name"=>"mnt-ref", "value"=>"RIPE-NCC-HM-MNT", "referenced-type"=>"mntner", "link"=>{"xlink:type"=>"locator", "xlink:href"=>"http://apps.db.ripe.net/whois/lookup/ripe/mntner/RIPE-NCC-HM-MNT"}}, 
    {"name"=>"mnt-by", "value"=>"RIPE-NCC-HM-MNT", "referenced-type"=>"mntner", "link"=>{"xlink:type"=>"locator", "xlink:href"=>"http://apps.db.ripe.net/whois/lookup/ripe/mntner/RIPE-NCC-HM-MNT"}}, 
    {"name"=>"source", "value"=>"RIPE", "comment"=>"Filtered"} 
] 

我不能依靠它每次都在相同的顺序。我有大约200.000个IP来检查。我如何搜索：

"name" => "address" 

，然后得到：

"value" => "Mira Internetsolutions ApS Nybovej 19 DK-7500 Holstebro Denmark" 

Answer 1

使用Array和Enumerable方法。在这种情况下，find：

data.find { |datum| datum['name'] == 'address' } 
# > {"name"=>"address", "value"=>"Mira Internetsolutions ApS Nybovej 19 DK-7500 Holstebro Denmark"}
