如何在 Coldfusion 中将 Active Directory objectGUID 转换为 UUID

Question

我有一个 CFLDAP 查询 returning objectGUID。如何在 ColdFusion 中将其转换为 8-4-4-4-12 模式的有效 UUID 字符串？

我已经指定了 returnAsBinary="ObjectGUID"，但是 toString(getLDAP.ObjectGUID) 没有 return 想要的结果。

更新：

我试过 binaryEncode():

<cfset guid = binaryencode(getLDAP.objectguid,"HEX")>

其中 return 个：

18E0CE3388B79C4EA4D73894AE8CD8F6

但我期待这个（由另一个我看不到它们的转换步骤的过程提取和提供）。

3cee018-b788-4e9c-a4d7-3894ae8cd8f6

嗯嗯……虽然不相配，但后半句是一样的。 a4d7-3894ae8cd8f6。

Answer 1

hummm... the last half is the same

有意思。 link 来自 this thread explains why. Apparently, it is more involved than just converting the binary into hex, in one shot:

First, know the sequence of the byte index that forms the Dashed String: [3] [2] [1] [0] - [5] [4] - [7] [6] - [8] [9] - [10] [11] [12] [13] [14] [15]

Next, apply bit masking to each and every single byte value accessed in the array.

Follow by converting to the Hex representation of the value.

Just make sure that the Hex value is a double digit value, meaning instead of "A", it should be "0A"

由于CF的数组是从1开始的，所以只需在位置上加上+1。这会以正确的顺序构建解码后的字符串（没有破折号，您可以使用字符串函数轻松添加它）。

 // Get GUID binary
 bin = yourQuery.objectGUID[rowNumber];
 // Extract bytes in this sequence
 order = [4,3,2,1, 6,5, 8,7, 9,10,11,12,13,14,15,16];
 // Stores converted bytes
 hex = [];

 for (pos in order) {
    // Apply mask to current byte and convert to hext 
    arrayAppend(hex, formatBaseN(BitAnd(bin[pos], 255), 16));
 }

 writeOutput("Hex string = "& arrayToList(hex, ""));

是的...我在一个旧的 CF post 中找到了它，它对我有用：

<CFLDAP ACTION="query" NAME="getLDAP" START="DC=info,DC=sys" SCOPE="subtree" STARTROW="1" maxRows="1"
SERVER="#domainCONTROLLER#" USERNAME="#USERNAME#" PASSWORD="#PASSWORD#" PORT="389" TIMEOUT="60"
ATTRIBUTES="sAMAccountName,mail,name,givenName,middleName,sn,title,department,ObjectGUID"
FILTER="sAMAccountName=#session.username#"
returnAsBinary = "ObjectGUID">

<cfset hexguid = BinaryEncode(getLDAP.objectguid,"Hex")>
<cfset sthex = toString(hexguid)>

<cfset GuidStr = mid(sthex,7,2)>
<cfset GuidStr = GuidStr & mid(sthex,5,2)>
<cfset GuidStr = GuidStr & mid(sthex,3,2)>
<cfset GuidStr = GuidStr & mid(sthex,1,2)>
<cfset GuidStr = GuidStr & mid(sthex,11,2)>
<cfset GuidStr = GuidStr & mid(sthex,9,2)>
<cfset GuidStr = GuidStr & mid(sthex,15,2)>
<cfset GuidStr = GuidStr & mid(sthex,13,2)>
<cfset GuidStr = GuidStr & mid(sthex,17,18)>
<cfset guid = left(GuidStr,8) & "-" & mid(GuidStr,9,4) & "-" & mid(GuidStr,13,4) & "-" & mid(GuidStr,17,4) & "-" & mid(GuidStr,21,18)>

你的更多 eloquent。谢谢！

这是我为 Pentaho Kettle "Modified Javascript" 步骤所做的 javascript 实现。

从Java接收objectGUID作为byte[16]数组，继续使用Java类进行处理

var b = objectGUID; // JavaArray

// the byte order is: [3] [2] [1] [0] - [5] [4] - [7] [6] - [8] [9] - [10] [11] [12] [13] [14] [15]
var theByteOrder = [3,2,1,0,5,4,7,6,8,9,10,11,12,13,14,15]; 

var ordered = new java.io.ByteArrayOutputStream(16);
theByteOrder.forEach(function(i) {
    ordered.write(b[i]); 
});

var bb = java.nio.ByteBuffer.wrap(ordered.toByteArray());
bb.order(java.nio.ByteOrder.BIG_ENDIAN);
var uuid = new java.util.UUID(bb.getLong(), bb.getLong());

var GUID = uuid.toString();

它不是 coldfusion 方言，是的，但希望它对扫描网络以解决类似任务的人有用。
