我有一個連接到Red Hat Satellite API的腳本。它列出了自提供日期以來發布的勘誤表。一旦生成列表，它會對接收到的每個勘誤再次調用API，以創建需要它的服務器列表。無法使用.emtpy？在Ruby腳本的數組中
#!/usr/bin/ruby
require "xmlrpc/client"
require "openssl"
require "ap"
# These are the parameters we use to create our XMLRPC client
params = {
# Dev
#host: "satellite-dev.example.com",
# Prod
host: "satellite.example.com",
path: "/rpc/api",
use_ssl: "true",
user: "user",
pass: "pass"
}
# Create our client using the parameters above
client = XMLRPC::Client.new(params[:host],params[:path])
# We don't want to bother with validating the Satellite SSL cert
# since it is self-signed; Disable this option in the client
client.instance_variable_get(:@http).instance_variable_set(:@verify_mode, OpenSSL::SSL::VERIFY_NONE)
# Create our Satellite API session
session = client.call("auth.login",params[:user],params[:pass])
channels_5 = ["rhel-x86_64-server-5","rhn-tools-rhel-x86_64-server-5"]
channels_6 = ["rhel-x86_64-server-6","rhel-x86_64-server-ha-6","rhel-x86_64-server-optional-6","rhn-tools-rhel-x86_64-server-6"]
channels_eus = ["rhel-x86_64-server-6.4.z","rhel-x86_64-server-6-rhs-2.1"]
all_channels = [channels_5, channels_6, channels_eus]
date = ARGV[0]
errata = Array.new
if date =~ /^\d\d\d\d-\d\d-\d\d$/
security = 0
puts "\n"
all_channels.each do |channels|
puts "#{channels}"
advisories = Hash.new
channels.each do |channel|
errata = client.call("channel.software.listErrata", session, channel, date)
errata.each do |erratum|
if erratum["advisory_type"] == "Security Advisory"
if advisories.key?(erratum["advisory"])
next
else
advisories[erratum["advisory"]] = {
advisory: erratum["advisory"],
synopsis: erratum["synopsis"],
issue_date: erratum["issue_date"][0..9]
}
end
else
next
end
end
end
advisories.keys.each do |advisory|
puts advisory
servers = client.call("errata.listAffectedSystems", session, advisory)
puts servers.class
# servers.each {|server| ap server} unless servers.emtpy?
end
puts "\n\n"
end
else
puts "Usage: #{$0} YYYY-MM-DD\n"
puts "YYYY-MM-DD is the start date for sought errata.\n\n"
puts " Ex. #{$0} 2014-04-08"
puts " Returns all errata released since 08 April 2014\n\n"
end
# Close the API session
client.call("auth.logout", session)
每個API調用都會返回一個結構數組，其中包含服務器ID號，名稱以及上次檢入Satellite的時間。
在上面的代碼中，我有一個塊，它顯示每個結構的內容，除非它是空的。不幸的是，這失敗了。我所得到的回報是
["rhel-x86_64-server-5", "rhn-tools-rhel-x86_64-server-5"]

Array
./sat_qa_patching.rb:88:in `block (2 levels) in <main>': undefined method `emtpy?' for []:Array (NoMethodError)
from ./sat_qa_patching.rb:83:in `each'
from ./sat_qa_patching.rb:83:in `block in <main>'
from ./sat_qa_patching.rb:60:in `each'
from ./sat_qa_patching.rb:60:in `<main>'
如果我打印出每個servers陣列我得到emtpy迴應：
["rhel-x86_64-server-5", "rhn-tools-rhel-x86_64-server-5"]

我敢肯定，他們是爲我所用servers.class並得到Array正在被返回的數組在每一個。
爲什麼它在.empty?方法錯誤，如果我回來應該支持它？
空拼寫爲「空」，而不是「emtpy」 – meagar
