Question

我正在尝试将Duo Web 2FA与我的ColdFusion应用程序集成。我的Coldfusion Server是运行Lucee 4.5.2.018 final的Windows Server 2012。我正在按照described here的GitHub方法进行操作。我收到以下错误消息，我不知道这是什么意思，或者从哪里开始进行故障排除：

invalid call of the function listGetAt, second Argument (posNumber) is 

invalid, invalid string list index [2]

The error occurred in C:\inetpub\wwwroot\serviceticket\test.cfm: line 82

80: <cfset request_sig = DuoWeb.signRequest(IKEY, SKEY, AKEY, USER)>
81: 
82: <cfset valid_app_sig = ListGetAt(request_sig, 2, ":")>
83: 
84:

这是我的测试页代码：

此实现的文档不多，但看起来很简单。此时，我只是想使此测试页正常工作，然后将其完整集成。

有人可以帮助我检测我在做什么错吗？这是我的错误的屏幕截图：

在我的CFC中将cftry / cfcatch替换为：

 <cfset duo_sig = signVals(arguments.sKey, arguments.username, arguments.iKey, variables.DUO_PREFIX, variables.DUO_EXPIRE)>
 <cfset app_sig = signVals(arguments.aKey, arguments.username, arguments.iKey, variables.APP_PREFIX, variables.APP_EXPIRE)>

这是它引发的错误：

Answer 1

cfifs太多了，您不需要它们（我了解您是从他们的测试页上获取的，但在这种情况下没有帮助）。

只需在创建对象后立即执行<cfdump var="#DuoWeb#" >，并希望它将揭示signRequest方法的签名。

如果可行，请一次分配request_sig并执行<cfdump var="#request_sig#" >

<h2>Test signRequest()</h2>

<cfset DuoWeb = CreateObject("component", "cfcs.DuoWeb")>
<cfdump var="#DuoWeb#" label="DuoWeb Object" />
<hr />

<cfset request_sig = DuoWeb.signRequest(IKEY, SKEY, AKEY, USER)>
<cfdump var="#request_sig#" label="request_sig" />

如果request_sig看起来不像其中包含:的字符串，则ListGetAt(request_sig, 2, ":")将引发错误。

希望对您有所帮助。

更新

cftry/cfcatch中有一个DuoWeb.cfc部分，因此您看不到真正的问题。

打开DuoWeb.cfc并暂时删除cftry/cfcatch，然后再次运行测试页。它应该在出现问题的地方抛出错误并提供更多信息。

在DuoWeb.cfc中替换为：

    <cftry>
        <cfset duo_sig = signVals(arguments.sKey, arguments.username, arguments.iKey, variables.DUO_PREFIX, variables.DUO_EXPIRE)>
        <cfset app_sig = signVals(arguments.aKey, arguments.username, arguments.iKey, variables.APP_PREFIX, variables.APP_EXPIRE)>
        <cfcatch>
            <cfreturn this.ERR_UNKNOWN>
        </cfcatch>
    </cftry>

与此：

        <cfset duo_sig = signVals(arguments.sKey, arguments.username, arguments.iKey, variables.DUO_PREFIX, variables.DUO_EXPIRE)>
        <cfset app_sig = signVals(arguments.aKey, arguments.username, arguments.iKey, variables.APP_PREFIX, variables.APP_EXPIRE)>

更新2

我已经尝试使用Lucee，但它不能按原样工作。看起来Lucee不喜欢"cookie"的{{1}}方法这一节中的DuoWeb.cfc一词。

在signVals中进行以下更改：

DuoWeb.cfc

对此（我的建议是<cfset var cookie = arguments.prefix & "|" & ToBase64(value)> <cfset var sig = hmacSign(arguments.key, cookie)> <cfreturn cookie & "|" & sig>）：

cookie__

应该可以解决问题。
