Object 合并Coldfusion中的两个对象（使用openBD）问题

我有以下代码块：

{
   "docs":[
      {
         "content":"I am",
         "ida":"23",
         "solrid":"23_solrid",
         "title":"Aaaaa",
         "dochighlighted":"I need"
      },
      {
         "content":"the most",
         "ida":"1",
         "solrid":"1_solrid",
         "title":"Bbbb",
         "dochighlighted":"to read"
      },
      {
         "content":"crap coder",
         "ida":"7",
         "solrid":"7_solrid",
         "title":"Cccc",
         "dochighlighted":"a lot of"
      },
      {
         "content":"in the whole universe!",
         "ida":"39",
         "solrid":"39_solrid",
         "title":"Dddd",
         "dochighlighted":"programming books!"
      }
   ]
}

第二个对象

是否可以将这两个对象合并为一个（从第二个复制到第一个）：

{
   "docs":[
      {
         "content":"I am",
         "ida":"23",
         "solrid":"23_solrid",
         "title":"Aaaaa",
         "dochighlighted":"I need"
      },
      {
         "content":"the most",
         "ida":"1",
         "solrid":"1_solrid",
         "title":"Bbbb",
         "dochighlighted":"to read"
      },
      {
         "content":"crap coder",
         "ida":"7",
         "solrid":"7_solrid",
         "title":"Cccc",
         "dochighlighted":"a lot of"
      },
      {
         "content":"in the whole universe!",
         "ida":"39",
         "solrid":"39_solrid",
         "title":"Dddd",
         "dochighlighted":"programming books!"
      }
   ]
}

我尝试了structAppend函数，但没有结果。此函数无法附加深嵌套元素。可以保留订单吗？这是因为上面的对象都是搜索引擎的结果，所以保持原始顺序非常重要。是否可以通过键引用合并两个对象？我这样问的原因是第一个对象是以特定的顺序从搜索引擎中出来的（注意solrid），但第二个对象可能不是。例如：

 *First object*

{
   "docs":[
      {
         "content":"I am",
         "ida":"23",
         "solrid":"23_solrid",
         "title":"Aaaaa"
      },
      {
         "content":"the most",
         "ida":"1",
         "solrid":"1_solrid",
         "title":"Bbbb"
      },
      {
         "content":"crap coder",
         "ida":"7",
         "solrid":"7_solrid",
         "title":"Cccc"
      },
      {
         "content":"in the whole universe!",
         "ida":"39",
         "solrid":"39_solrid",
         "title":"Dddd"
      }
   ]
}

 *Second object*

{
   "docs":[
      {
         "solrid":"39_solrid",
         "dochighlighted":"programming books!"
      },
      {

         "solrid":"7_solrid",
         "dochighlighted":"a lot of"
      },
      {
         "solrid":"1_solrid",
         "dochighlighted":"to read"
      },
      {
         "solrid":"23_solrid",
         "dochighlighted":"I need"
      }
   ]
}

是否有可能达到与上述相同的合并结果？

{
   "docs":[
      {
         "content":"I am",
         "ida":"23",
         "solrid":"23_solrid",
         "title":"Aaaaa",
         "dochighlighted":"I need"
      },
      {
         "content":"the most",
         "ida":"1",
         "solrid":"1_solrid",
         "title":"Bbbb",
         "dochighlighted":"to read"
      },
      {
         "content":"crap coder",
         "ida":"7",
         "solrid":"7_solrid",
         "title":"Cccc",
         "dochighlighted":"a lot of"
      },
      {
         "content":"in the whole universe!",
         "ida":"39",
         "solrid":"39_solrid",
         "title":"Dddd",
         "dochighlighted":"programming books!"
      }
   ]
}

非常感谢,

荣幸地

这会让你走得更远：

<cffunction name="ArrayOfStructsMerge" returntype="array" access="public" output="yes">
  <cfargument name="left"  type="array"  required="yes">
  <cfargument name="right" type="array"  required="yes">
  <cfargument name="id"    type="string" required="yes">

  <cfset var result = Duplicate(arguments.left)>
  <cfset var element = "">
  <cfset var key = "">
  <cfset var currentId = "">
  <cfset var lookup = StructNew()>

  <cfloop array="#result#" index="element">
    <cfif IsStruct(element) and StructKeyExists(element, arguments.id)>
      <cfset currentId = element[arguments.id]>
      <cfset lookup[currentId] = element>
    </cfif>
  </cfloop>

  <cfloop array="#arguments.right#" index="element">
    <cfif IsStruct(element) and StructKeyExists(element, arguments.id)>
      <cfset currentId = element[arguments.id]>
      <cfif StructKeyExists(lookup, currentId)>
        <cfloop collection="#element#" item="key">
          <cfset lookup[currentId][key] = Duplicate(element[key])>
        </cfloop>
      <cfelse>
        <cfset ArrayAppend(result, Duplicate(element))>
      </cfif>
    </cfif>
  </cfloop>

  <cfreturn result>
</cffunction>

它以非破坏性方式运行（不修改原始对象）。可以这样称呼：

<cfset result = ArrayOfStructsMerge(obj1.docs, obj2.docs, "solrid")>
<cfdump var="#result#">

也是。很代码。你认为你能把你的问题“一般化”并把它缩减到原来的10分之一吗？@Tomalak你好，代码不是重点。它只是作为参考。你认为包括这些“意大利面”会让这篇文章乏味吗？是的，有点多。据我所知，您正在询问如何合并两个简单结构。@Tomalak。谢谢您的回复。我已经测试了你的代码，但它不起作用。循环中的index=“i”出现问题。我找不到哪里出了问题，因为我是新手。任何帮助都将不胜感激。Tom@anarchos78功能是固定的。我对

的记忆有些混乱。我不知道该如何感谢你。你的回答是分析性的。做得好。竖起大拇指。最后一个问题：为了达到您的编码技能，我必须做什么？很荣幸。Tom@anarchos78谢谢，那太好了我有将近20年的经验，仅此而已。所以我想你要做的就是保持下去
