我正在处理一个需要比较两个哈希值内的值的项目。哈希键＆＃39;标题＆＃39;有一个数组作为其值，其中包含两个问题的标题。 我想要实现的是，如果在issue_yaml中的标题存在于fwparse_issues中，则将标题保存在issue_yaml（哈希中的数组）中，否则删除它＆＃39;。
示例代码：
fwparse_issues = [
{:section_title=>"Security Audit",
:ref=>"FILTER.LOG.DROP",
:title=>"Filter Drop Rules Were Configured Without Logging"},
{:section_title=>"Security Audit",
:ref=>"LOGGING.SYSLOG.NO.ENCRYPTION",
:title=>"Syslog Logging Configured With No Encryption"},
{:section_title=>"Security Audit",
:ref=>"FILTER.RULE.EENE",
:title=>"Filter Rules Allow Packets To A Network Destination"},
{:section_title=>"Security Audit",
:ref=>"FILTER.RULE.EEER",
:title=>"Filter Rules Allow Packets To A Port Range"},
{:section_title=>"Security Audit",
:ref=>"BANNER.NO.POST.LOGON.MESSAGE",
:title=>"No Post Logon Banner Message"},
{:section_title=>"Security Audit",
:ref=>"LOGGING.SYSLOG.SEVERITY",
:title=>"Weak Syslog Severity Level Configured"},
{:section_title=>"Security Audit",
:ref=>"FILTER.RULE.NEEE",
:title=>"Filter Rules Allow Packets From A Network Source"}]
issue_yaml = {"ABC-1234"=>
{"title"=>["No Pre-Logon Banner Message", "No Post Logon Banner Message"],
"desc"=>"some text",
"rec"=>"recommendations go here",
"ref"=>"references"},
"ABC-5678"=>
{"title"=>"SSH Protocol Version 1 Supported",
"desc"=>"some text\nwhich spans\nmultiple lines\n",
"rec"=>"recommendations go here",
"ref"=>"references"}}
fwparse_issues.each do |issue|
issue_yaml.keys.each do |key|
if issue_yaml[key]["title"].is_a?(Array)
unless issue_yaml[key]["title"].include?(issue[:title])
issue_yaml[key]["title"].delete(issue[:title])
end
end
end
end
我最终需要的是：
{"ABC-1234"=>
**{"title"=>["No Post Logon Banner Message"],**
"desc"=>"some text",
"rec"=>"recommendations go here",
"ref"=>"references"}}
但相反，粗线最终成为：
{"ABC-1234"=>
{"title"=>["No Pre-Logon Banner Message", "No Post Logon Banner Message"],
"desc"=>"some text",
"rec"=>"recommendations go here",
"ref"=>"references"},
本质上，除非比特不起作用。我花了这么长时间看待它的那种情况之一我甚至不能再思考了。如果我改变了＆＃39;除非＆＃39;如果＆＃39;如果＆＃39;它会删除＆＃34;没有后登录横幅消息＆＃34;来自issue_yaml所以反过来似乎有效！

这应该可以满足您的需求。
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.UI;
public class SearchThroughCards : MonoBehaviour {
public int size;
// Use this for initialization
void Start () {
StartCoroutine(GetCards());
}
// Update is called once per frame
IEnumerator GetCards()
{
UnityWebRequest www = UnityWebRequest.Get("https://www.ygohub.com/api/all_cards");
yield return www.Send();
if (www.isNetworkError)
{
Debug.Log(www.error);
}
else
{
// Show results as text
Debug.Log(www.downloadHandler.text);
RootCardList cardList = JsonUtility.FromJson<RootCardList>(www.downloadHandler.text);
size = cardList.card.Count;
Debug.Log(cardList.card);
foreach (string str in cardList.card)
{
Debug.Log(str);
}
}
}
}
编辑：改为使用就地回答。
哪个收益率：

using System.Collections.Generic;
using UnityEngine;
[System.Serializable]
public class RootCardList
{
public string status;
public List<string> card;

假设fwparse_issues在示例中给出，issue_yaml定义如下。
issue_yaml =
{"ABC-1234"=>
{"title"=>["No Pre-Logon Banner Message",
"No Post Logon Banner Message"],
"desc"=>"some text",
"rec"=>"recommendations go here",
"ref"=>"references"},
"ABC-5678"=>
{"title"=>"SSH Protocol Version 1 Supported",
"desc"=>"some text\nwhich spans\nmultiple lines\n",
"rec"=>"recommendations go here",
"ref"=>"references"},
"ABC-5679"=>
{"title"=>"Weak Syslog Severity Level Configured",
"desc"=>"some text\nwhich spans\nmultiple lines\n",
"rec"=>"recommendations go here",
"ref"=>"references"},
"ABC-1230"=>
{"title"=>["No Post Logon Banner Message",
"No Post Logon Banner Message"],
"desc"=>"some text",
"rec"=>"recommendations go here",
"ref"=>"references"}
}
我们首先从fwparse_issues构建一个标题数组。
titles = fwparse_issues.map { |h| h[:title] }
#=> ["Filter Drop Rules Were Configured Without Logging",
# "Syslog Logging Configured With No Encryption",
# "Filter Rules Allow Packets To A Network Destination",
# "Filter Rules Allow Packets To A Port Range",
# "No Post Logon Banner Message",
# "Weak Syslog Severity Level Configured",
# "Filter Rules Allow Packets From A Network Source"]
我们现在可以构造所需的哈希值。
issue_yaml.each_with_object({}) do |(k,v),h|
keepers = [*v["title"]].select { |s| titles.include?(s) }
h[k] = v.merge("title"=>keepers.size==1 ? keepers.first : keepers) unless keepers.empty?
end
#=> {"ABC-1234"=>{"title"=>"No Post Logon Banner Message",
# "desc"=>"some text",
# "rec"=>"recommendations go here",
# "ref"=>"references"},
# "ABC-5679"=>{"title"=>"Weak Syslog Severity Level Configured",
# "desc"=>"some text\nwhich spans\nmultiple lines\n",
# "rec"=>"recommendations go here", "ref"=>"references"},
# "ABC-1230"=>{"title"=>["No Post Logon Banner Message",
# "No Post Logon Banner Message"],
# "desc"=>"some text",
# "rec"=>"recommendations go here",
# "ref"=>"references"}
# }
如果s = v["title"]是字符串，则[*v["title"]]会返回[s]。如果arr = v["title"]是数组，则[*v["title"]]会返回v。例如，如果v = "hi"，[*v] #=> ['hi'];如果v = ['hi', 'ho']，[*v["title"]]返回['hi', 'ho']。
让我们更仔细地检查所执行的计算。我们首先创建一个枚举器。
enum = issue_yaml.each_with_object({})
#=> enum=#<Enumerator:0x00000000e5be38>
我们可以通过将枚举器转换为数组（或执行enum）来检查枚举器enum.entries将生成的值。
enum.to_a
#=> [[["ABC-1234", {"title"=>["No Pre-Logon Banner Message",
# "No Post Logon Banner Message"],
# "desc" =>"some text",
# "rec" =>"recommendations go here",
# "ref" =>"references"}], {}],
# [["ABC-5678", {"title"=>"SSH Protocol Version 1 Supported",
# "desc" =>"some text\nwhich spans\nmultiple lines\n",
# "rec" =>"recommendations go here",
# "ref" =>"references"}], {}],
# [["ABC-5679", {"title"=>"Weak Syslog Severity Level Configured",
# "desc" =>"some text\nwhich spans\nmultiple lines\n",
# "rec" =>"recommendations go here",
# "ref"=>"references"}], {}],
# [["ABC-1230", {"title"=>["No Post Logon Banner Message",
# "No Post Logon Banner Message"],
# "desc"=>"some text",
# "rec"=>"recommendations go here",
# "ref"=>"references"}], {}]]
enum生成一系列元素，这些元素传递给块并分配给块变量。生成并传递给块的第一个元素如下。
(k,v), h = enum.next
#=> [["ABC-1234", {"title"=>["No Pre-Logon Banner Message",
# "No Post Logon Banner Message"],
# "desc"=>"some text",
# "rec" =>"recommendations go here",
# "ref" =>"references"}], {}]
Ruby消除了这个数组的歧义，并为块变量赋值。
k #=> ABC-1234
v #=> {"title"=>["No Pre-Logon Banner Message",
# "No Post Logon Banner Message"],
# "desc"=>"some text",
# "rec" =>"recommendations go here",
# "ref"=>"references"}
h #=> {}
我们现在可以执行块计算。
a = v["title"]
#=> ["No Pre-Logon Banner Message", "No Post Logon Banner Message"]
b = [*a]
#=> ["No Pre-Logon Banner Message", "No Post Logon Banner Message"]
keepers = b.select { |s| titles.include?(s) }
#=> ["No Post Logon Banner Message"]
keepers.empty?
#=> false
keepers.size == 1,
#=> true
c = keepers.first
#=> No Post Logon Banner Message
h[k] = v.merge("title"=>c)
#=> {"title"=>"No Post Logon Banner Message",
# "desc"=>"some text",
# "rec"=>"recommendations go here", "ref"=>"references"}
h #=> {"ABC-1234"=>{"title"=>"No Post Logon Banner Message",
# "desc" =>"some texte",
# "ref"=>"references"}}
其余的计算方法类似。
创建键"titles"数组（字符串）的所有值可能更方便，即使这些数组只包含一个字符串。
